On KDE Plasma. I was trying to install a legacy nvidia driver. After reboot - first the SDDM theme didn´t load (was replaced by fallback theme) - then after logging in I got BSOD, but dmenu, konsole and gedit opened up. I tried all kinds of thing. I have disabled/re-enabled the nouveau modeset in /etc/default/grub, messed around with mhwd in the terminal. It seems, that I couldn´t install the nvidia driver (I got error messages that make no sense to me). So I believe that the drivers are messed up. I rolled back the kernel to 5.4 and installed kernel-headers and base-devel dkms so that I could install the nvidia driver. System update does nothing. I have reinstalled xorg. After that just BSOD - no greeter. This was the error message that was displayed when I could still see the SDDM greeter: /usr/sharesddm/themes/breeze-ghostpresent-sddm/Main.qml:27:1:plugin cannot be loaded for module “org.kde.plasma.core”: Cannot load library /usr/lib/qt/qml/org/kde/plasma/core/libcorebindingsplugin.so:(/usr/lib/libGLX.so.0: undefined symbol: _glDispatchForceUnpatch)
systemctl status sddm says its active and running. Attempting " startx " results in an error. inxi -G shows …" driver: N/A " so there is neither a nvidia or nouvaeu driver assigned? or configs are screwed up.
So I need help fixing the issue.
When I attempt to start x from the terminal it returns to the terminal with the error … " Could not resolve keysym XF86KbdLcdMenu5Errors ".
I am still on BSOD and no assigned drivers?. Assistance would be greatly appreciated.
