Once all that is done the upstream default DDX should be able to be utilized. It's named modesetting, utilizes KMS, and is newer technology than the reverse-engineered nouveau DDX. NVidia driver installation can leave behind blacklisting and custom libraries that replace standard libraries, so uninstallation instructions from NVidia driver installation must be followed to eliminate those obstacles to utilizing any FOSS DDX offering acceptable performance. Rebuilding initrds after purging proprietary NVidia remnants may be necessary as well.

    Have installed kernel headers however nvidia driver can't find them. Still think something wrong with kernel version installation/update.

    Suse rpms should be purged completely I think. However will check now. Have not installed manual scripts.

    Hi
    You should only need kernel-default-devel and maybe kernel-macros installed. But follow user mrmazda's instructions first.

    I've checked mrmazda's instructions: all is clear there and uninstalled cleanly. Also reinstalled 5.2.5 kernel, re-run grub2-mkconfig - now newsest kernel is running - still no luck. Any other suggestions?

    Hi
    So no nvidia, did you run mkinitrd as well?

    Yes, no nvidia, yes run mkinitrd. Failed to install 430.x, now trying 390.x - seems works: see login screen. What is wrong with nouveau, why it stopped to work? And 430.x definitely does not support my card. Now need to reinstall nvidia driver on every kernel update?

    Hi
    I would suggest a bug report to Nvidia then, or browse their forum for further clues...

    430.x vs 390.x driver is not a big issue and subject of this topic. Good at least 390.x is working now. Why nouveau stopped to work and how to restore?

    Hi
    Perhaps your running Wayland rather than Xorg?

    Code:
    echo $XDG_SESSION_TYPE
    Aside from that you would need input from a Plasma user, I'm a Gnome user
