[SOLVED] After most recent update, KDE Plasma shows mouse only

Digitalman65 · 2024-10-11 19:39:35

I have three screens and the mouse even moves between the three but does not show my desktop. I have a RTX3060ti graphic card and I'm pretty sure I saw the drivers being updated. But since the mouse shows, maybe not a driver issue. I'm not sure what to do to fix this. I tried to get to a shell by hitting alt-F2 but nothing appeared. I saw this in another post. I even tried to boot in the LTS version but that did help, same issue. I guess I should have expected that. Any help would be appreciated.

I was able to get to a text prompt with ctrl-alt-F3, logged in, updated my system but the problem remains. It doesn't show the login prompt, just the mouse. I keep wondering if it's because I have to keep hitting the reset button on my PC because after sleeping, the desktop doesn't reappear. This happens every time it sleeps. KDE turns the screens off and back on without problems, just happens when the system itself goes to sleep.

i experienced this problem before when i was installing KDE plasma on arch too. I know that if you are using sddm select on top "Plasma (X11)" or something like that to it to run. you installed Arch with the Plasma DE in the right order Archinstall -> xorg -> sddm -> plasma -> kde-apllications ->

 systemctl enable sddm

 systemctl enable NetworkManager

reboot? For me when i did this in the right order Plasma worked just fine. BTW idk about graphics card and i think its not important.

Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Try to add "nvidia_drm.fbdev=0" to the https://wiki.archlinux.org/title/Kernel_parameters
There're also some complaints about plasma 6.2 but w/ "It doesn't show the login prompt, just the mouse" there's possibly somethign wrong w/ SDDM and your reset button habits might have lead to file corruption…

try uninstalling and reinstalling KDE

And what do you suppose this is gonna achieve unless there're corrupted files (in which case re-installing the affacted packages would do, except it's apparently more a SDDM than a KDE issue)?
Common windows tactics tend to be a waste of time and in this case will leave maybe more file corruption behind.

I think that's a thing. I don't get the SDDM login prompt, just the mouse pointer. I've been looking on what files might be involved and how to reset it.

The bootloader will not be relevant to the sanity of the grapical.target
If you see a mouse cursor, the display server started, but if you expect to see some SDDM login screen and don't then the issue is sddm.
Re-installing that might help.
Reverting to the default breeze theme might help.
The journal will most likely contain some sddm error messages that will shed light on this.

That got me thinking. I recalled I changed the theme but didn't associate that change with the issue since it was two days prior. So I found the kde_settings.conf file and removed the value for

[Theme]
Current=

Now I get the SDDM login prompt.

Thanks!

If you want qt5 themes to work you need to install the optional qt5-declarative dependency for SDDM

Arch Linux
