Hi
I recently want to try the KDE plasma interface and I installed Kubuntu (Ubuntu with plasma interface).
but when I want to start up to install it freeze and just the mouse moves.
I tried to install Kubuntu with safe graphic mode and it was installed.
after I reboot and want to sign in to Kubuntu after I enter my password and hitting enter I see a black screen and nothing works
and after a few seconds, it logs out.
I even tried to update and upgrade from recovery mode but it doesn't change.
and try to install KDE plasma in kali Linux and from normal ubuntu.
what should I do I really like the plasma how I can fix this?

Hi!

Try to login in another tty without Wayland/X and read the errors provided by `journalctl`. Also show the graphic card(s) used and the kernel module loaded.
kali is not ment to be installed, it is a testing system. So stay with Kubuntu if you try to install a daily driver system.

Thanks for replying
I'm a little new at this can you explain more specific.
when I press alt+ctrl+f4 i enter the CLI login screen and i see the tty4.

After pressing ctrl-alt-F4 you can enter your username and password (blind). The login there should work and not result in a relogin-loop. If this happens, you could have an exit-command, loop or another error in a .bashrc/.bash_aliases file or .profile configuration file. If it is the only account on this system the easiest would be to change this using a live-usb-stick.

If the login works you can check permissions in homefolder using

Code: Select all

find $HOME ! -user $USER -ls

No output means no problem. If there are files shown you can change the owner using `sudo chown user:group /path/to/file` where user is your login name and group is optional and on Kubuntu the same as the username.

Finding further errors:

Code: Select all

journalctl -b -xep 0..4

will show warnings and errors since last boot. To show all of them remove the «-b».

Checking the graphics card(s) and driver:

Code: Select all

lspci -nnk | grep -A3 "\[03..\]:"
