Title: [SOLVED] Dark KDE screen
Post by: orca on 2019/11/27, 15:06:42

Hi there
I have a KDE desktop machine, with an NVIDIA graphic card, regularly fully upgraded.It worked seamlessly for several months and practically always turned on, until last Monday morning,: when I tried to use it, the screen was just plain dark (in fact both screens, since I've got two monitors)..I fully upgraded the system and am able to use it from a plain terminal... When I boot it, the GRUB and the SDDM screens show up fine (the bootup messages also do not show any errors).After I type my login and password, sometimrs I can see a glance of my graphical desktop area, but it immediately goes dark :_(
Any suggestions??

I see "nouveau" on the list of unloaded drivers -- did you not remove it before installing the nvidia-driver?  You might try removing the nouveau driver, or blacklisting it.  Also, I'm not sure what the latest driver should be for your GTX 650, but if you don't use the legacy driver, then there are newer drivers.  I also run KDE/Plasma with nvidia graphics -- here is my graphics sedtup:

Code: [Select]

Dear HendrikL,
Purging print-manager, which might have been installed after I changed my printer (from an HP to a Brother) and had used Brother's deb package, DID work!!! And the printer still seems to be working fine.
Thanks a lot!!! What should I do to concretely thank you? I was even considering buying a new machine :-(
Thaks again!!!!!!!! Happy everything!!!!

Dear dibl,
I just use to full-upgrade regularly my system and it just works, including the upgrading of the nvidia drivers, so I guess perhaps I would rather not change other things, since the suggestion by hendrikL did solve my specific problem. Thanks a lot anyway!!
