MIRROR SMARTPHONE USING SCRCPY 2.0

1. Hi Copilot, does my OPPO RENO 5G smartphone support "Miracast mobile phone screen mirroring" function ? THANKS Copilot.

Yes ✅ — your OPPO Reno 5G supports wireless screen mirroring (Miracast/Screencast). OPPO phones running ColorOS 7.0 or later include a built‑in feature called Screencast, which allows you to mirror your phone’s display to a TV, monitor, or other Miracast‑compatible device Tenorshare kingshiper.com omhape.com.

📱 How OPPO Reno 5G Handles Screen Mirroring

Feature name: OPPO calls it Screencast (sometimes referred to as Wireless Display or Screen Mirroring).
Technology: It uses the Miracast protocol, so you can connect to TVs, projectors, or monitors that support Miracast.
Requirements:
- Your Reno 5G must be on ColorOS 7.0 or newer (most Reno 5G units shipped with ColorOS 7 or later).
- The receiving device (TV, monitor, projector, or dongle) must support Miracast/Wireless Display.
Alternatives: If your TV doesn’t support Miracast, you can still mirror using third‑party apps or devices like Chromecast, but that uses Google Cast instead of Miracast.

🛠️ How to Use Screencast on OPPO Reno 5G

Open Quick Settings: Swipe down from the top of your screen.
Find “Screencast” or “Wireless Display”: Tap it.
Select your device: Your Reno 5G will search for nearby Miracast‑enabled displays.
Connect: Tap the target device, and your phone screen will appear on the larger display.

🔎 Comparison: Screencast vs Other Methods

Method	Tech Used	Works With	Notes
Screencast	Miracast	Smart TVs, Miracast dongles	Built‑in, no extra apps needed
Chromecast	Google Cast	Chromecast, Android TV	Requires Google Home app
HDMI Adapter	Wired	Any HDMI display	Stable, but requires cable
Third‑party apps	Varies	PC, TV, projector	May add features like recording

👉 Bottom line: Your OPPO Reno 5G does support Miracast screen mirroring through its built‑in Screencast feature. As long as your TV or display supports Miracast, you can mirror wirelessly without extra apps.

Would you like me to walk you through troubleshooting tips (e.g., if your TV doesn’t show up or the connection fails)?

2. Hi Copilot , when I press Windows + P on my Windows 10 PC/Desktop , I did not get the message that says "Connect to a wireless display" but I get the message that says " PC screen only" and the message that says "Duplicate" and the message that says "Extend" and the message that says "Second screen only" , so Copilot , what do you think that could go wrong here ? Please help ! THANKS.

Got it — thanks for explaining clearly. The fact that you only see PC screen only / Duplicate / Extend / Second screen only but not “Connect to a wireless display” strongly suggests that your Windows 10 PC/Desktop does not support Miracast as a receiver (or the feature is disabled).

🔍 Why This Happens

Hardware limitation:
- Miracast requires both your Wi‑Fi adapter and graphics card/driver to support it.
- Many desktops (especially with Ethernet only or older Wi‑Fi cards) don’t support Miracast.
Drivers not installed/updated:
- Outdated Wi‑Fi or GPU drivers can prevent Miracast from showing up.
Feature not enabled:
- On Windows 10, you need the Wireless Display optional feature installed to act as a Miracast receiver.

🛠️ How to Check if Your PC Supports Miracast

Press Windows + R, type dxdiag, and press Enter.
Click Save All Information → open the saved text file.
Look for Miracast under the “System Information” section.
- If it says Available, with HDCP, your PC supports Miracast.
- If it says Not supported, then your hardware doesn’t support it.

✅ Fixes / Next Steps

Install Wireless Display feature:
- Go to Settings → Apps → Optional features → Add a feature.
- Search for Wireless Display and install it.
Update drivers:
- Update your Wi‑Fi adapter and graphics drivers via Device Manager or manufacturer’s website.
Use alternatives if unsupported:
- If your desktop doesn’t support Miracast, you can still mirror using:
  - HDMI cable (wired connection).
  - Microsoft Wireless Display Adapter (external dongle).
  - Google Chromecast or similar casting devices.

👉 Bottom line: Your OPPO Reno 5G supports Miracast, but your Windows 10 desktop likely doesn’t have Miracast receiver capability enabled or supported. Checking with dxdiag will confirm.

Would you like me to walk you through the step‑by‑step installation of the Wireless Display feature on Windows 10, so you can test if that solves it?

3. Hi copilot , my OPPO RENO 5g DO NOT HAVE "screencast" settings , so , what can i do in order to mirror the image of my OPPO Reno 5G to my Windows 10 Laptop ? THANKS.

Thanks for clarifying — if your OPPO Reno 5G doesn’t show a Screencast option, don’t worry. You still have several ways to mirror your phone’s screen to a Windows 10 laptop:

🔧 Alternative Methods to Mirror OPPO Reno 5G to Windows 10

1. Use Third‑Party Apps (Wireless)

Install apps like ApowerMirror, LetsView, or Vysor on both your phone and laptop.
These apps use Wi‑Fi or USB to mirror your screen.
Advantage: Easy setup, often more stable than native Miracast.
Note: Some advanced features may require a paid version.

2. Google Chromecast / Android TV (Wireless)

Plug a Chromecast into your TV or use an Android TV with built‑in casting.
On your OPPO Reno 5G, open apps like YouTube or Google Home → tap the Cast icon.
This mirrors or streams content to your TV, and you can use your laptop as a secondary display if connected to the same network.

3. USB Cable + Software (Wired)

Connect your Reno 5G to your laptop via USB.
Use apps like Scrcpy (free, open‑source) or Vysor.
Advantage: Very stable, no Wi‑Fi needed.
Scrcpy is lightweight and doesn’t require installation on your phone.

4. Microsoft Your Phone (Phone Link)

Install Phone Link (formerly Your Phone) on Windows 10.
Pair your Reno 5G via Bluetooth/Wi‑Fi.
While it doesn’t fully mirror the screen in all cases, it lets you access notifications, messages, and some apps directly from your laptop.

✅ Recommended Path

Since your Reno 5G doesn’t show Screencast, the most reliable options are:

Scrcpy (USB wired) if you want free, stable mirroring.
ApowerMirror or LetsView (Wi‑Fi wireless) if you prefer wireless mirroring.

👉 Bottom line: Your Reno 5G can still mirror to Windows 10, but you’ll need to use third‑party apps or USB tools since the built‑in Screencast option isn’t available.

Would you like me to give you a step‑by‑step guide for Scrcpy (the free USB method) so you can try it right away?

Windows 10 Operating System _ Disable Password on Wake from Sleep

MICROSOFT Copilot Answer

Optional: Disable Password on Wake from Sleep

If the PC goes to sleep, it may still ask for a password.

Open Settings → Accounts → Sign-in options.
Under Require sign-in, set it to Never.

⚠️ Important Notes

This makes the PC completely unsecured — anyone can access it without a password. Since it’s for your daughter’s casual use, that may be fine, but keep in mind if the PC has sensitive files.
If you ever want to re-enable security, just reverse the steps above.

Would you like me to also show you how to set up a child account with no password at all (so she has her own space but doesn’t need to log in), or do you prefer keeping everything under one account?

Windows 10 Operating System _ Prevent Windows 10 machine FROM GOING TO SLEEP

Copilot , when you say , "the PC goes to sleep" ............. What does it mean ? Does it mean that the PC/Desktop will go BLANK or the screen goes BLANK after a certain period of time ? Is it true that if I set or activate the "screensaver" on my Windows 10 machine , it will prevent my Windows 10 machine FROM GOING TO SLEEP ? Copilot , could you please explain ?

MICROSOFT Copilot Answer

Great question — this is one of those areas where Windows terminology can be confusing. Let’s break it down clearly:

🌙 What “Sleep” Means in Windows 10

Sleep mode is a low-power state.
The PC saves everything you’re working on in memory (RAM), then powers down most components to conserve energy.
The screen goes blank/black, fans usually stop, and the computer looks “off,” but it can wake up quickly when you press a key or move the mouse.
Think of it like “pausing” the computer — not shutting it down, but not fully running either.

🖼️ What a Screensaver Does

A screensaver is just a visual animation (like your “Bubbles”) that runs while the PC is still awake.
It does not prevent sleep. In fact, if your PC is set to go to sleep after a certain period, the screensaver will run for a while, then the PC will still go to sleep.
Screensavers are mostly decorative today — they don’t serve the old purpose of protecting CRT monitors anymore.

⚡ Key Difference

Screensaver = PC is awake, just showing animations.
Sleep mode = PC is in low-power state, screen is blank, waiting to be woken up.

✅ How to Control This

If you want the PC to stay awake and only show the screensaver (never go to sleep):

Go to Settings → System → Power & sleep.
Under Sleep, set both “On battery power, PC goes to sleep after” and “When plugged in, PC goes to sleep after” to Never.
Keep your screensaver enabled — now the PC will show bubbles indefinitely instead of sleeping.

👉 So to answer directly:

Yes, when the PC “goes to sleep,” the screen goes blank and the machine enters low-power mode.
No, setting a screensaver does not stop the PC from sleeping — you must change the Power & sleep settings to prevent that.

Would you like me to also show you how to make the PC wake instantly without asking for a password when it comes out of sleep (similar to what we did for the screensaver)?

Windows 10 Operating System _ Stop Password Prompt After Screensaver

MICROSOFT Copilot Answer

Stop Password Prompt After Screensaver

By default, Windows asks for a password when resuming from screensaver. You can disable that.

Right-click on the desktop → choose Personalize.
Go to Lock Screen → scroll down and click Screen saver settings.
In the Screen Saver Settings window:
- Make sure “On resume, display logon screen” is unchecked.
Click Apply → OK.

Now, when the bubbles screensaver ends, pressing a key will return directly to the desktop.

3. Optional: Disable Password on Wake from Sleep

If the PC goes to sleep, it may still ask for a password.

Open Settings → Accounts → Sign-in options.
Under Require sign-in, set it to Never.

⚠️ Important Notes

This makes the PC completely unsecured — anyone can access it without a password. Since it’s for your daughter’s casual use, that may be fine, but keep in mind if the PC has sensitive files.

The Surprising Psychology Behind People Who Love Staying at Home

The truth about people who prefer to stay home

Many people in modern culture, particularly since the COVID pandemic, do struggle with loneliness. But what can we learn from a certain subset of people who seemingly choose to be alone — and thrive on being so?

How healthy alone time can be good for us

Psychologists are finally turning their attention to “homebodies”: people who feel better when they’re at home, in their own environments.

Although their more extroverted and action-oriented friends and family members might worry that homebodies are lonely, shy, or otherwise fear leaving their home or engaging with others, researchers are now finding that many homebodies are none of those things.

People who prefer solitude or their home environment might, in fact, harbor some of the strongest mental…

Why Some People Refuse to Participate on Social Media

The psychology of people who don’t need likes to feel alive

We’ve all seen them. People who have social media profiles that are very light on details, and which feature only a generic avatar where their profile photograph is supposed to be.

We may wonder: Are these people Luddites who don’t believe in engaging wholeheartedly with technology and social media? Do they just not have the know-how to snap and post a selfie? Why don’t they just get with the times already?

Turns out, people who sit out social media participation may understand the technology just fine. Whether or not they choose to engage with it might be due more to their personalities.

The pros and cons of social media and online interaction

Many people who use social media jumped into it wholeheartedly. During the last twenty years, it has become more normalized for people to share personal details like photographs, travel diaries, and thoughts online, as well as to like, emphasize, or share other peoples’ thoughts.

Recent statistics show that over 1 million selfies are taken on Instagram every single day, while approximately 93 million selfies are “uploaded to Snapchat daily.”

'What do you want the Minister to do? Read prayers?' - Dr Maza declines religious affairs portfolio, calls it his last option

Dr Mohd Asri, better known as Dr Maza, is expressing a firm stance on the kind of ministerial role he believes holds actual influence.

SHAH ALAM – If you thought the Religious Affairs Ministry was the ultimate power move, former Perlis Mufti Datuk Dr Mohd Asri Zainul Abidin (a.k.a. Dr Maza) is here to say, "Think again."

Dr Maza just made it brutally clear that he prefers a position like the Home Ministry or Education Ministry, arguing that the Religious Affairs portfolio carries "little real authority."

In a firm statement on the kind of ministerial role that holds actual influence, Dr Maza asserted that the Religious Affairs Ministry was the one role he absolutely did not want in any country.

Why? Because, in his view, the responsibilities are largely ceremonial rather than impactful.

He threw shade by suggesting that if individuals genuinely want to test their abilities, they should aim for serious portfolios like Home Affairs or Education.

Dr Maza saw limited scope for real policymaking within the religious portfolio, questioning its practical purpose with this iconic line:

“What do you want the Religious Affairs Minister to do? Read prayers? Then you go and perform hajj,” he quipped.

He elaborated that the role, as he understood it, revolves around official duties that simply don't translate into meaningful governance.

"Everything that is discussed cannot be translated into anything else other than attending official functions," he said.

Dr Maza sealed the deal by making it clear that he would decline the position, emphasising he had zero interest in the offer and viewed the Religious Affairs Minister role as his last option, a massive political flex you need to see to believe.

Linux Operating System _ Multiseat on Ubuntu 25.10 using ASTER SOFTWARE _1

Hi Copilot , could you please teach me or give me a step-by-step procedure on how to do "Multiple Concurrent Users on a Single PC using ASTER SOFTWARE" with the help of UBUNTU 25.10 , in other words , "Multiple Concurrent Users on a Single UBUNTU 25.10 PC/Desktop using ASTER SOFTWARE" . Copilot , I hope you could really give me a step-by-step procedure on this interesting project because I am only an average Linux user . THANKS Copilot for your answer.

MICROSOFT Copilot Answer

Multiseat with ASTER on Ubuntu 25.10 overview

You want two or more users working concurrently on one Ubuntu PC, each with their own monitor, keyboard, and mouse. ASTER Multiseat provides a guided UI to create “workplaces” and assign devices, now with official Linux support. Below is a practical, step‑by‑step setup tailored for Ubuntu 25.10, from install to daily use, plus fixes for common issues YouTube dokwiki.ibik.ru.

Requirements and preparation

Hardware:
- Displays: Either multiple outputs on one GPU or separate GPUs; one monitor per user.
- Inputs: One keyboard and one mouse per user; USB hubs help keep pairings consistent.
- Optional audio: USB sound dongles per seat simplify mapping.
System:
- Ubuntu 25.10 desktop, admin account with sudo.
- Stable power settings (avoid USB power‑down and sleep while using multiseat). ASTER recommends high‑performance power plan and disabling monitor sleep and hibernation to prevent device dropouts dokwiki.ibik.ru.
License:
- ASTER requires activation after trial; obtain installer and license from official distributors asterindian.in.

Install ASTER on Ubuntu

Download ASTER for Linux
- Get the Linux installer from the official ASTER/IBIKSoft channels. Verify checksum if provided. Asterindian provides download and requirements, and the ASTER wiki links the download page asterindian.in dokwiki.ibik.ru.
Install the package
- If it’s a .deb:
```
sudo dpkg -i aster*.deb || sudo apt -f install
```
- If it’s a script/tarball: follow the vendor’s README for Linux installation steps and dependencies, then run the installer UI.
Reboot (recommended)
- After install, reboot to ensure services and udev rules initialize cleanly.
Activate ASTER
- Launch the ASTER control app, apply your license or start the trial. The vendor documentation covers activation workflow asterindian.in.

Tip: During installation, ASTER suggests optimizing power parameters and disabling “Fast Boot”/sleep behavior to improve stability with multiple seats dokwiki.ibik.ru.

Create workplaces and assign devices

Open ASTER control center
- Start the ASTER UI from the app menu or via terminal. The Linux tutorial demonstrates the workflow for creating workplaces on Ubuntu YouTube.
Add workplaces (seats)
- Create Workplace 1 (seat0) and Workplace 2 (seat1). Name them clearly (e.g., “Dad”, “Daughter”). ASTER’s UI is designed to guide you through adding seats on Linux YouTube.
Assign displays per workplace
- For each workplace, select the monitor to attach. If you have two GPUs, bind each seat to its GPU; if one GPU, map separate outputs to different workplaces. The ASTER tutorial shows display mapping on Ubuntu YouTube.
Assign input devices
- Plug in each keyboard/mouse pair and assign them to the intended workplace. If identical models appear, use port labels or unplug/replug to identify. ASTER’s Linux UI supports input device mapping per workplace YouTube.
Assign audio (optional)
- Map audio devices per workplace; USB sound cards are easiest to differentiate and assign in ASTER YouTube.
Save and apply configuration
- Apply changes, then enable ASTER multiseat mode. The Linux tutorial demonstrates enabling and testing after configuration YouTube.

Start sessions and daily use

Start ASTER and launch seats
- Enable ASTER. Each connected monitor should show a login screen for its assigned workplace, controlled only by that workplace’s keyboard/mouse YouTube.
Log in separately
- Use distinct user accounts (e.g., you and your daughter). Work independently on the same PC without input/display overlap YouTube.
Stopping ASTER
- Use the control center to stop multiseat when needed; sessions end per workplace. Vendor guidance covers normal start/stop operations YouTube.

Troubleshooting and tips

A monitor shows no greeter:
- Ensure the display is assigned to the correct workplace. Check cables and GPU outputs. Reapply configuration in ASTER’s UI YouTube.
Keyboard/mouse control the wrong seat:
- Reassign devices in ASTER. If devices are identical, label ports/hubs and re‑plug one pair at a time to identify correctly YouTube.
Audio not isolated:
- Prefer USB audio per seat; then assign in ASTER to avoid pulse routing confusion YouTube.
Sleep/USB power issues:
- Disable monitor sleep/hibernation and USB power‑down. ASTER’s installer recommends high‑performance power settings to avoid device dropouts dokwiki.ibik.ru.
Installer or license concerns:
- Use trusted sources for downloads and licensing. Asterindian provides detailed info on safe download and licensing options asterindian.in.

If you tell me your GPU(s), how your monitors are connected, and the brands of keyboards/mice, I can walk you through the exact mapping in the ASTER UI step by step for your hardware.

Linux Operating System _ Multiseat on Ubuntu 25.10 _1

Hi Copilot , the other day you gave me an explanation or you taught me how to do MULTISEAT on a DEBIAN 13 PC/Desktop . But on second thought , I would prefer to do MULTISEAT on a UBUNTU 25 Linux . I guess I feel more comfortable with UBUNTU 25 Linux than DEBIAN 13 , so Copilot , do you think you can teach me or give me a step-by-step procedure on how I can do MULTISEAT on a UBUNTU 25.10 Linux PC/Desktop , so much so that , my daughter is doing his own thing on her UBUNTU 25 PC/Desktop , and at the same time , I am doing my own thing on her UBUNTU 25 PC/Desktop ? THANKS Copilot.

MICROSOFT Copilot Answer

Got it — you want to set up multiseat on Ubuntu 25.10 so that you and your daughter can each use the same PC at the same time, with separate monitors, keyboards, and mice. Here’s a clear step‑by‑step guide tailored for Ubuntu:

🖥️ What multiseat means

Multiseat allows one physical computer to act like multiple independent desktops. Each “seat” has:

Its own monitor (GPU or GPU output)
Its own keyboard and mouse
Optionally, its own audio device

Ubuntu uses systemd‑logind and a display manager (GDM or LightDM) to manage seats.

⚙️ Step‑by‑step procedure

1. Prepare hardware

Connect two monitors (ideally on separate GPUs, or one GPU with multiple outputs).
Connect two keyboards and two mice (USB hubs help keep them grouped).

2. Identify devices

Run these commands to list devices:

ls -l /dev/input/by-id
ls -l /dev/dri

/dev/input/by-id → shows keyboards/mice.
/dev/dri/card0, /dev/dri/card1 → show GPUs.

To get vendor/product IDs for inputs:

udevadm info --attribute-walk --name=/dev/input/eventX

3. Create udev rules for seat assignment

Make a new rules file:

sudo nano /etc/udev/rules.d/90-seat1.rules

Add entries like:

# Assign keyboard to seat1
SUBSYSTEM=="input", ATTRS{idVendor}=="abcd", ATTRS{idProduct}=="1234", ENV{ID_INPUT_KEYBOARD}=="1", ENV{ID_SEAT}="seat1"

# Assign mouse to seat1
SUBSYSTEM=="input", ATTRS{idVendor}=="abcd", ATTRS{idProduct}=="5678", ENV{ID_INPUT_MOUSE}=="1", ENV{ID_SEAT}="seat1"

# Assign GPU card1 to seat1
SUBSYSTEM=="drm", KERNEL=="card1", ENV{ID_SEAT}="seat1"

Replace abcd/1234 with the actual IDs from udevadm.

4. Reload udev and check seats

sudo udevadm control --reload
sudo udevadm trigger
loginctl list-seats
loginctl seat-status seat1

You should see seat1 with its devices.

5. Configure display manager

GDM (default in Ubuntu):
- Edit /etc/gdm3/custom.conf and ensure Wayland is enabled:
```
#WaylandEnable=false
```
- Restart GDM:
```
sudo systemctl restart gdm
```
- Each seat should now get its own login screen.

LightDM (alternative, more control with Xorg):

sudo apt install lightdm
sudo dpkg-reconfigure lightdm

Then edit /etc/lightdm/lightdm.conf:

[Seat:seat0]
xserver-command=X -seat seat0 -sharevts -novtswitch

[Seat:seat1]
xserver-command=X -seat seat1 -sharevts -novtswitch -isolateDevice PCI:1:0:0

Replace PCI:1:0:0 with the BusID of your second GPU.

Restart LightDM:

sudo systemctl restart lightdm

6. Test

Each monitor should show a login prompt.
Each keyboard/mouse pair should only control its assigned seat.
Log in separately and run independent sessions.

🔧 Troubleshooting

Devices not bound correctly: Double‑check vendor/product IDs in udev rules.
Only one greeter appears: Ensure GPU assignment is correct (card1 vs card0).
Inputs overlap seats: Use USB hub path matching in udev if vendor/product IDs are identical.
Audio: Use USB sound cards and assign them to seats with similar udev rules.

👉 If you share your GPU model(s) and how your keyboards/mice are connected, I can refine the exact udev rules for your setup. Would you like me to tailor the config for a single GPU with two outputs, or are you planning to use two separate GPUs?
