Hi, I've an issue with a few games not locking the mouse to it's window, for example Dying Light and Don't Starve Together.

Both games are running in fullscreen, but mouse keeps escaping to the secondary screen.

Now, I know that Gamescope has a solution for this, the problem is that Gamescope doesn't work on my laptop and doesn't seem to really work on many laptops, so that's not an option at the moment.

I know Wine has an option for this, but I forgot how it's called, though nevertheless, it doesn't also doesn't help in Dying Light and Don't Starve Together has a native Linux version, so I can't really change Wine settings for it.

Are there any other options, or specific KDE/Hyprland settings I could apply to force the window to grab the mouse? I would like to avoid disconnecting the display if possible.

If you're experiencing graphical issues, crashes, or performance problems in GNOME (similar to what you saw in KDE Plasma), here’s a complete troubleshooting and optimization guide to fix them:

1. Fix Graphics Drivers (NVIDIA/AMD/Intel) For NVIDIA:

bash sudo apt purge *nvidia* && sudo ubuntu-drivers autoinstall sudo reboot - Verify with: bash nvidia-smi # Should show GPU stats

For AMD/Intel (Open-Source Drivers):

bash sudo apt install mesa-utils mesa-vulkan-drivers vulkan-tools vulkaninfo | grep "GPU name" # Check if Vulkan works

2. Disable GNOME Compositor (Fixes Lag & Crashes)

GNOME’s compositor can cause issues with games. Disable it temporarily: ```bash

Disable for current session

killall -3 gnome-shell

Disable permanently (if needed)

gsettings set org.gnome.mutter experimental-features "['x11-randr-fractional-scaling']" ```

3. Optimize Game Performance For Steam Games (Proton):

In Steam → Game Properties → Launch Options, add: PROTON_USE_DXVK=1 PROTON_NO_ESYNC=1 DXVK_ASYNC=1 %command%

For Native Linux Games:

Force OpenGL/Vulkan optimizations: bash export __GL_SYNC_TO_VBLANK=0 # Disable VSync for OpenGL export vblank_mode=0 # Disable VSync for Vulkan

4. Switch from Wayland to X11 (More Stable)

GNOME defaults to Wayland, which can cause issues. Switch to Xorg: 1. Log out. 2. Click the gear icon (⚙️) on the login screen. 3. Select "Ubuntu on Xorg" (not "Ubuntu" or "Wayland"). 4. Log back in.

5. CPU & GPU Performance Tweaks CPU Governor (Performance Mode)

bash sudo apt install cpufrequtils echo 'GOVERNOR=performance' | sudo tee /etc/default/cpufrequtils sudo systemctl restart cpufrequtils

GPU Power Limits (NVIDIA)

bash sudo nvidia-smi -pm 1 # Enable persistent mode sudo nvidia-smi -pl 200 # Set power limit (200W, adjust as needed)

6. Check for Overheating & Throttling

bash sudo apt install lm-sensors sensors # Check CPU/GPU temps - If overheating: bash sudo apt install thermald sudo systemctl start thermald

7. Reset GNOME Settings (If Still Buggy)

bash dconf reset -f /org/gnome/ sudo reboot ⚠️ Warning: This resets all GNOME customizations.

8. Test with a Minimal GNOME Session

bash sudo apt install gnome-session --reinstall Then log in with "GNOME Classic" (simpler, fewer effects).

Final Checks

• Verify GPU is detected: bash glxinfo | grep "OpenGL renderer"
• Check for errors: bash journalctl -xe | grep -i "error\|nvidia\|amd\|gpu"

If Nothing Works...

• Try a different DE (like Xfce or KDE Plasma again).
• Use a gaming-optimized distro (Pop!_OS, Nobara Linux).
• Reinstall latest NVIDIA drivers from the official website.

Expected Results

✅ Smooth gameplay (no lag)
✅ No crashes when Alt+Tabbing
✅ Proper GPU utilization

Here's a complete guide to optimize graphics performance for gaming on KDE Plasma without crashes:

1. Graphics Driver Configuration For NVIDIA:

bash sudo nvidia-settings Configure: - "Performance Mode" → Maximum Performance - "OpenGL Settings" → VSync=Off, Triple Buffering=On - Enable "Force Full Composition Pipeline" if using multi-monitor

For AMD/Intel:

bash sudo apt install mesa-utils mesa-vulkan-drivers vulkan-tools

2. KDE Plasma Optimization

Disable compositor for gaming: bash kwriteconfig5 --file kwinrc --group Compositing --key Enabled false kwriteconfig5 --file kwinrc --group Compositing --key LatencyPolicy high

3. Environment Variables

Add to ~/.profile: ```bash

NVIDIA Optimizations

export __GL_SHADER_DISK_CACHE=1 export __GL_SHADER_DISK_CACHE_PATH="$HOME/.nv" export __GL_THREADED_OPTIMIZATIONS=1 export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json

AMD/Intel Optimizations

export RADV_PERFTEST=aco # Better AMD Vulkan performance export AMD_VULKAN_ICD=RADV ```

Reload: bash source ~/.profile

4. Proton (Steam) Optimization

In Steam game properties > Launch Options: PROTON_USE_DXVK=1 PROTON_NO_ESYNC=1 DXVK_ASYNC=1 %command%

5. CPU/GPU Performance Modes

```bash

Set CPU to performance governor

sudo apt install cpufrequtils echo 'GOVERNOR=performance' | sudo tee /etc/default/cpufrequtils sudo systemctl restart cpufrequtils

Prevent GPU throttling (NVIDIA)

sudo nvidia-smi -pm 1 sudo nvidia-smi -pl 250 # Set power limit (adjust wattage as needed) ```

6. System Tweaks

```bash

Reduce swap usage

sudo sysctl -w vm.swappiness=10

Improve filesystem cache

sudo sysctl -w vm.vfs_cache_pressure=50

Disable mitigations (for raw performance)

sudo nano /etc/default/grub # Add: mitigations=off sudo update-grub ```

7. Game-Specific Optimizations Borderless Window Mode:

• Enable in-game if available
• Or force via: bash xprop -id $(xdotool getactivewindow) -f _NET_WM_STATE 32a -set _NET_WM_STATE _NET_WM_STATE_MAXIMIZED_HORZ,_NET_WM_STATE_MAXIMIZED_VERT

Resolution Scaling:

bash xrandr --output HDMI-1 --scale 0.75x0.75 # For 4K->1080p downscaling

8. Verification Tools

Check your setup with: ```bash

Graphics info

glxinfo | grep -i "opengl renderer" vulkaninfo | grep -i "gpu name"

Performance monitoring

nvidia-smi -l 1 # NVIDIA real-time stats radeontop # AMD real-time stats ```

9. Final Steps

```bash

Update everything

sudo apt update && sudo apt upgrade -y

Reboot to apply all changes

sudo reboot ```

Troubleshooting

If games still underperform: 1. Check for thermal throttling: bash sensors # Monitor temperatures 2. Try different Proton versions (Experimental/GE) 3. Test with barebone window manager: bash sudo apt install openbox openbox --replace & steam

This setup provides: ✅ Maximum FPS with stable performance
✅ Reduced input lag
✅ Proper GPU utilization
✅ Crash-free Alt+Tab functionality

Has anyone also experienced such a bad frametime and lags in Witcher 3 on Linux?
Frametime looks crazy and feels that way, basically unplayable. DX11 mode seems don't have this issue but it stutters too much...

It looks like valve is working on, and close to achieving, wireless VR on linux. They've had it working on windows since forever with what they call "vrlink", but it now seems like that's finally making it to linux.1

I've been working on hacking it together myself, but noticed that they steam had overwritten my driver in the newest update. I looked into it the binaries, and they seem to indicate that they've successfully ported the whole shebang to linux and vulkan.

Currently they're not distributing the necessary spirv shaders. That could be due to some contractual relationship with AMD, since they were using AMD's now deprecated AMF library on windows.

So on Windows when I run eDuke32 it picks up the OGG music files just fine and plays that music instead of the MIDI files. But on Linux when I put the same music folder into the directory, it doesn't detect my OGG music files at ALL and only plays the MIDI music. How do I fix this? I wanna hear the CD music for Duke 3D not the 8 Bit music.

Hey there, -- I'm having some trouble getting R6 Extraction to work. Here's my specs:

Ryzen 7 7800x3d

RTX 3080

Pop!_OS 22.04

Steam is installed on deb not flatpak

I've tried Proton Hotfix, Experimental, and 10.0-1.

I tried looking at ProtonDB and I saw that one report said to make sure Proton BattlEye Runtime is installed, which it is.

It shows the splash screen, opens up Ubisoft connect (which I can even click on the toolbar icon and open up the program, but launching it still isn't working. I'm logged into Ubisoft..

I'm trying to run it through Lutris, and I encountered a separate issue that might help upon solving. I have my steam account linked, but whenever I run the R6 Extraction on there I get this error:

https://preview.redd.it/bi3rqrtsau5f1.png?width=460&format=png&auto=webp&s=be0d9f2166863ac62d408c565c795789aa2d9182

Which also happens when I try to run the app through the ProtonDB website. Is there something off about my Steam install that could be causing this issue?

I'm a Windows user, but after hearing about Windows allegedly favoring certain CPUs and GPUs—and other issues with the platform—I’m thinking of switching to Linux.

That said, I want the transition to be as smooth and unnoticeable as possible. I still want to use all my apps and have fun without problems.

However, I'm worried about messing things up and potentially having to wipe my C: drive.

Can someone recommend a Linux distro that's very user-friendly and has strong community and developer support?

(thanks chat gpt for writting this)

PS GPU : AMD Radeon RX 6500 XT CPU : AMD Ryzen 5 4600G with Radeon Graphics RAM : 16 GB VRAM 4080

I want to be able to play almost any video game, im more into single player games, so games with anti cheats most likely wont be a issue i play alot of minecraft, a bit of roblox I use OBS, brave browser, discord, steam and AMD and small things i dont think will be a issue, i have a bit of experience with linux by hacking my school chromebook with a linux terminal so i know how to install applications.

I think we can agree Linux gaming going mainstream is heavily dependent on Valve doing well with Steam Deck/SteamOS which so far they have been pretty successful with. More people on SteamOS, means more people on Linux, means more developer support, means better ecosystem which means more people. Microsoft has now officially announced a collaboration with Asus for a ROG Ally Xbox handheld and from the looks of it, they just copied SteamOS with an optimized version of Windows and an Xbox interface. I think this could be a real blow to Valve, the one major advantage they had over Windows handhelds was the cleaner interface, optimized software, the ease of use and features like suspend/resume are all gone now, while Windows still retains its one major advantage that being game compatibility.

This was something I've been fearing for sometime now, there was even some speculation from The Phawx that the Xbox series S model was just MS paving the way for a handheld in the future which made a lot of sense to me. Welp, seems like they are all in now, what do you think the impact for Valve, SteamOS and Linux gaming as a whole will be when this thing comes to market?

As per title, I'm new to using Steam on Linux, but what's this Remote Desktop pop-up?

Am I hacked / compromised?

Or does someone just want to see me playing?

It's gone though, after i dismiss it.

I never set up the Remote Desktop feature on my Fedora 42 Workstation.

The game is a simple Counter-Strike 2, no Proton I think, just Linux Runtime.

Hey guys, does anyone has trouble with emotes/spray wheel? When I try to use it both for assigning and emote usage I can't spin it anymore. No matter how much I move the mouse the selector just won't move. It just sticks on the upper left item.

I tried to fix the game through Steam but didn't work. I playing using last Proton-GE. Do anyone has this trouble?

I’m planning to switch to Linux (daily use + gaming) and I read that to get NVIDIA proprietary drivers working with Secure Boot, I need to enroll MOK keys using mokutil.

That’s where I’m getting kinda nervous. It feels like I'd be interfering with low-level BIOS/firmware stuff, and I'm not sure how safe that is. Like, could this open up some firmware-level vulnerabilities or let something like a persistent RAT slip through? Or am I just overthinking it? Would it be safer to just disable Secure Boot instead?

For context: I'm using RTX 3060 and Intel i3-12100F + planning to use KDE (idk what distro yet)

The Archwiki warns against installing the native runtime due to possible compatibility issues. Though I've tested the native version on another PC (where I rarely actually play games) and it's much snappier, so I'm interested in switching. Has anyone actually run into issues using the native version?
