Thread: Upgraded My Nvidia Driver. Now KDE Looks Like It's Ignoring X11 Config

    Default Re: Upgraded My Nvidia Driver. Now KDE Looks Like It's Ignoring X11 Config

    Nvidia has apparently decided to make their drivers open source and integrate them into the Linux kernel, but from the tiny bits of information about it that I've heard, they're doing it in a staged process where they're splitting it up into smaller components and merging them bit by bit. This 32 bit package could be part of this process, but I honestly don't know. I just know that, like Kieltux said, if I want to run 32 bit software (such as Steam) I need the 32 bit package installed.

    I tried uninstalling the 32 bit package anyway, just to see if it might help, but unfortunately it didn't. My next logical step was to roll back to the G05 packages and see if everything went back to normal after a reboot like I expected it would, but that didn't help either. As things stand now, I'm pretty sure I have the same packages installed as I did when everything was working fine, but I'm still stuck with this stretched out, low resolution setting (presumably 1024×768@76Hz). Here's what inixi and zypper say about the state of the system right now:

    Code:
    home:~ # inxi -G;zypper se -is g05 
    Graphics:  Device-1: NVIDIA GM204 [GeForce GTX 970] driver: N/A  
               Display:server: X.org 1.20.3 driver: nouveau FAILED: nvidia unloaded: fbdev,modesetting,vesa

    i  | x11-video-nvidiaG05       | package | 470.129.06-lp153.50.1
    
    Thankfully, FrankyU2's post gives me a bit of reason to be hopeful. I haven't tried it yet, and I was worried that the conf.rpmsave file might have been overwritten during the process of rolling back to the G05 packages, but there does seem to still be a difference between the files which might dig me out of this hole. I compared the two files with diff, and diff shows that the only difference between the files is a line containing a reference to something that used to break Nvidia drivers years ago:
    Code:
    home:~ # diff /etc/modprobe.d/50-nvidia-default.conf /etc/modprobe.d/50-nvidia-default.conf.rpmsave    
    2d1 
    < options nvidia-drm modeset=1


    I remember that, years ago, I used to need to have (think) "nomodeset" specified on the OS selection menu of Grub, otherwise the Nvidia driver couldn't be loaded. So I'm going to try restoring the rpmsave file and hope for the best. Wish me luck!

    Restored the rpmsave backup, but it made no difference to the low resolution. Inixi says:
    Code:
    home:~ # inxi -G 
    Graphics:  Device-1: NVIDIA GM204 [GeForce GTX 970] driver: N/A  
               Display:server: X.org 1.20.3 driver: nouveau FAILED: nvidia unloaded: fbdev,modesetting,vesa  
               resolution: <xdpyinfo missing>  
               OpenGL:renderer: llvmpipe (LLVM 11.0.1 256 bits) v: 4.5 Mesa 20.2.4


    As far as I know, everything is as it was before I switched to G06 and the driver loading started to fail. Anyone have any suggestions?

    Just read mrmaxda's post again because I didn't quite understands it the first time, and I noticed that he was suggesting to use inxi -Ga, rather than just -G. I did notice that xdpyinfo was missing because I remember I had that in the notes I wrote for myself about getting the driver installed, but then lost. I just avoided installing it to reduce the number of variables in this problem. It's installed now, though, so here's the output of inxi with xdpyinfo installed,

    Hi Ray,

    Sorry, I'm not that sophisticated with these things. If you're back at the same level that has been working before, I'm stuck. nvidia is still not loaded. You may yet make sure that nouveau is blacklisted. Others may be able to give better advice.

    Be sure nomodeset is not set in grub

    That's okay. I'm thankful to anyone who even tries to offer solutions. My knowledge about hardware configuration is negligible. I tend to write little tools and bits of things for friends and family so, to them, I'm their computer guy, but whenever they ask me about computer hardware I always tell them the same thing: "Hardware is Voodoo". Even on Windows, there's just too much that can go wrong with it, and I know that I know far too little about most of it.

    I've installed xdpyinfo and the 32 bit G05 module again, but yeah, as far as I can tell, all of my installed packages are exactly as they were before I installed the G06 modules which caused the problem, but the problem still persists. The only X11 config file I've ever actually changed has remained unchanged throughout the entire process, so I have absolutely no idea where to look for potential problems.

    Given that it won't be long before 15.4 hits the shelves, I'm mostly just interested in getting this solved as more of a learning exercise. It might be helpful to go into the transition the 15.4, armed with a tiny bit more GPU troubleshooting knowledge, especially given that Nvidia is reportedly making significant changes to their drivers.

    I opened /boot/grub2/grub.cfg in Kate and did Ctrl+F nomodeset and nothing was found, is this what you mean?

    I also made a backup of 50-nvidia-default.conf before I overwrote it with the rpmsave version as suggested by FrankyU2. I notice that the backup contains references to modeset, but the /etc/modprobe.d/50-nvidia-default.conf file that I'm using now doesn't contain any references to modeset. Would this be the equivalent of having nomodeset in Grub?

    I can't even remember what modeset is about, it's been so long since I even had to give any thought to whether or not it is in use.

    Please provide output from
    Code:
    # cat /var/log/Xorg.0.log | susepaste
    so we can see what X is and isn't doing.

    When correctly running on FOSS, this is what output from inxi on a supported NVidia GPU should resemble:

    If xf86-video-nouveau is installed, most likely instead of modesetting as above, you would find nouveau in its place as loaded display driver.
    I suggest to try fully purging the proprietary drivers now installed, verifying success by getting the FOSS drivers working similar to above. Once you've reached that state, you should be able to install appropriate NVidia drivers successfully.
