From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Debian 12 Firefox games run terrible when i press buttons or use the mouse (feddit.nl)

Hi all,

I recently installed Debian 12 on my Lenovo Legion 5 Pro, and am using the GNOME desktop (x11). From time to time I play a game called survev.io . It's a browser battle royale game, not hard on graphics.

I have an Nvidia rtx3060 and have the proper drivers installed. I checked using nvidia-smi and Firefox is using the Nvidia gpu.

The issue is that the game runs smoothly until I press a button or move the mouse. Then the framerate decreases significantly and it becomes unplayable.

I already tweaked the following settings in Firefox to no avail:

  • gfx.webrender.all = True
  • enabled hardware acceleration
  • layers.acceleration.force-enabled = TRUE
  • gfx.x11-egl.force-enabled = true

And now I'm out of ideas. The game itself isn't too important to me, but other browser games do the same, so it's a wider issue I want to solve.

Any ideas on how to resolve this?

I just installed a fresh Debian 12 VM and it looks like this on the login screen:

However, I don't have an Nvidia GPU, so maybe their drivers disable Wayland?

There is something in the Debian wiki for Wayland on Nvidia: https://wiki.debian.org/NvidiaGraphicsDrivers#Wayland

It seems indeed the nvidia drivers disable wayland. I played around in Firefox settings a bit more and a setting around input delay seems to have fixed it for now. I hope it stays that way. If not, I'll migrate to chromium
