Graphics issue on multiseat setup

MangyCat commented 4 months ago

Description

So i got a multiseat setup, seat0 is using Intel IGPU, seat1 is nvidia gpu, the issues only seem to be happening on the nvidia gpu while at the intel gpu's seat everything is fine nothing wrong, both gpus have Mesa loaded (Not using propietary driver). This issue didnt use to happen before on the nvidia gpu when it was just one seat, everything worked fine.

The actual issue happening is the carts being invisible, like only their shadow being visible, like ghost carts. and I cannot even see the powerups other carts are using for example (fly swatters, bubble gum protection)

And the other thing is that the seat1 side is actually very sluggish even though it has a nouveau card and should logically be faster than the intel igpu even on the lowest settings!

Steps to reproduce

Have a multiseat configuration (1 Intel gpu and one nvidia gpu running on nouveau)
Have lightdm desktop enviorment and login to enlightenment wayland (It doesnt matter if wayland or xorg, same thing happens on both)
Get on supertuxkart
Select your ghostly kart?
Race with other ghosts of carts
Be disappointed
Exit game

Configuration

STK release version: 1.4

STK Source (PPA, distribution package, official binary, etc.): Distribution package from pacman

System: Arch Linux

Graphics card: GT630 and Intel HD 2000 (Nvidia gf108 variant, running nouveau)

CPU: Intel I5 2400

Gamepads/keyboards models if related to the issue:

Additional information

I attempted to reset supertuxkart configuration by deleting the supertuxkart folder in .config and the supertuxkart folder in .local/share, it didnt work and resulted in the same bug. Also sometimes the issue disappears but its a hit or miss its like rolling a dice. Even when playing other games i encounter this pattern of the nvidia gpu being slow while the Intel gpu is fast for example minecraft.

try add <card vendor="Mesa" os="linux" disable="TextureBufferObject"/> to the graphics_restrictions.xml

Darin755 commented 2 months ago

I'm not a SuperTuxKart developer but perhaps you could try installing the proprietary Nvidia driver? It sounds like a low level issue and not a bug with the game.

qwertychouskie commented 2 months ago

The Nouveau Gallium3D driver is known to have a number of significant correctness, stability, and performance issues, and is in the process of being deprecated. Unfortunately, your card appears to be Fermi-based, which means it will likely not get NVK support. If the new "NAK" shader compiler ever gets back-ported to the Nouveau Gallium3D driver, it should theoretically fix most issues, but the Mesa developers currently do not have any plans to do so. Please consider testing with the proprietary Nvidia driver, as it will almost certainly give the best possible experience for your particular hardware.

Alayan-stk-2 commented 1 month ago

The needed fixes would have to happen on the driver's end, not on ours. Your best chance is, as suggested by previous posters, to not use the Nouveau drivers. They work too poorly for 3D gaming.

You can use the config setting suggested by Benau to try to fix the issue on your end, but we cannot apply it to the project at large without downgrading graphics for compliant card-driver combos, or investing excessive time in trying to figure out which combos work and which don't.
