Note that this sees like quite strange bug, Turing should be supported since 8.3 I believe. More info about GPUS: NVIDIA Corporation TU104GL [Quadro RTX 5000] [10de:1eb0] (rev a1) NVIDIA Corporation TU117 [GeForce GTX 1650] [10de:1f82] (rev a1) > conf file was automatically generated and driver for GPU is nouveau.
What automatically generated it? We use the generic modesetting X driver by default for Tesla and newer for NVIDIA, which is like GeForce 8000 and six generations older than Turing, so it's not especially surprising that the nouveau X driver wouldn't work.
xong.conf was generated by Xorg -configure. For this pascal gpu ( GP108 [GeForce GT 1030] ) what is predecessor of turing it works just fine with nouveau inside xorg.conf The nouveau (x.org) driver does not in fact support Turing or newer, you have to use the generic driver named 'modesetting'. We should probably fix X -configure to not configure nouveau at all to be honest. This is an xserver bug if it's anything, nouveau upstream doesn't support Turing or Ampere and we're not likely to use its support even if it did. After evaluating this issue, there are no plans to address it further or fix it in an upcoming release. Therefore, it is being closed. If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened. The needinfo request[s] on this closed bug have been removed as they have been unresolved for 120 days |
Description of problem: Unable to create X session with turing GPU, tested with TU104 and TU117, when using /etc/X11/xorg.conf . conf file was automatically generated and driver for GPU is nouveau. When driver for GPU is set to modesetting or there is no xorg.conf X session will be created and gpu is fully functional. Can be also reproduced on RHEL 8.4 How reproducible: 100% Steps to Reproduce: 1. have turing GPU 2. create xorg.conf 3. try to log into X session from gdm Actual results: you will be returned into GDM Expected results: you will get X session Additional info: (II) LoadModule: "nouveau" (II) Loading /usr/lib64/xorg/modules/drivers/nouveau_drv.so (II) Module nouveau: vendor="X.Org Foundation" compiled for 1.20.1, module version = 1.0.15 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 24.0 (II) NOUVEAU driver (II) NOUVEAU driver for NVIDIA chipset families : RIVA TNT (NV04) RIVA TNT2 (NV05) GeForce 256 (NV10) GeForce 2 (NV11, NV15) GeForce 4MX (NV17, NV18) GeForce 3 (NV20) GeForce 4Ti (NV25, NV28) GeForce FX (NV3x) GeForce 6 (NV4x) GeForce 7 (G7x) GeForce 8 (G8x) GeForce GTX 200 (NVA0) GeForce GTX 400 (NVC0) (II) [drm] nouveau interface version: 1.3.1 (EE) Unknown chipset: NV167
