Yes the Nouveau driver is quite buggy and that might never be fixed for older GPUs.
Perhaps a better way forward for the GeForce 9400 is to use a supported configuration with the Nvidia-340 driver. That would require installing Ubuntu 22.04 (the original release, not 22.04.1+) so you have a stable setup where the driver works and the kernel will always support that driver. Just make sure it's the original 22.04 release and not 22.04.1 etc. Download: https://old-releases.ubuntu.com/releases/22.04/ubuntu-22.04-desktop-amd64.iso Checksum: https://old-releases.ubuntu.com/releases/22.04/SHA256SUMS Alternatively, if you want to venture into unsupported territory then you could stay on 25.10 using an old enough kernel to support Nvidia-340 (from https://kernel.ubuntu.com/mainline/) and manually install the Nvidia-340 driver. I'm not sure what other issues that might cause but it's certainly not supported by Ubuntu. Another alternative would be to disable the 'nouveau' driver completely by blacklisting it in one of /etc/modprobe.d/blacklist*.conf -- That would give you a supported, bug-free, but slow 25.10 experience. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2138586 Title: [nouveau] Graphics corruption on GeForce 9400 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2138586/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
