Manjaro (KDE) stuck on black screen with cursor before login screen

My manjaro-kde just shows black screen with cursor. I can move the cursor though…GRUB is also working fine and it show me all the options.I basically have 2 kernels installed one is 5.8(default running) and other is 5.4(LTS). I tried to boot using both of them using GRUB advanced option but its just stuck on the black screen.I haven’t updated my system recently and neither did I messed with any of the my system files.

Using an live debian-usb I have some gathered some logs see if it helps

switch to tty and reinstall KDE

Any other option beside this?


Yes there is, Please do a search on this forum, You will find a solution. Just put black screen in search and a plethora of answers will come up.

Could you find a solution?
I have the same error too

Press Ctrl + Alt + F2 to switch to TTY

Then sudo systemctl start sddm
systemctl reboot

I did it in the first place and I also tried reinstalling KDE but it didn’t work.
