Plasma/X login interesting issue

English Install/Boot/Login
1

Hi all,

I recently got a new laptop (Lenovo Yoga 520) and I have cloned my \home partition from my old laptop (which runs Leap 42.2 flawlessly) to the new one running Tumbleweed in order to take advantage of the 2-in-1 with stylus functionalities.

Every driver and hardware seems to be working fine, however a rather interesting issue appear when I reboot/shutdow and try to login again. After the splash screen the display keeps black with only the mouse arrow (which moves normally).

What I have tested that didn’t work:
1- I can login to IceWM, but sometimes I’m unable to run any application. However, after logging out and logging in to IceWM 2 or 3 times the applications come back to normal on IceWM environment;
2- Tested multiple kernels 4.9 LTS , 4.11, 4.14 ;
3- Deleted ~/.cache and reset ~/.config to defaults;
4- Tried to “killall plasmashell” and “kstart plasmashell”, but the usual message about exporting to display appears;
5- Tried different variations of poweroff, shutdown and reboot commands ;

The only workaround that has worked until now:
1- On login screen after a reboot/shutdown I log in outside Plasma/X using Ctrl+Alt+F1, then I come back to GUI login screen with Alt+F7 and type my password. It works everytime!

I would like some help here.
Any idea on what might be the cause of this issue/bug?

Thanks,

Try creating a new user and then test the behaviour with that user account. Any different?

1: video driver details?

# inxi -G -c0

2: display manager in use?

# ps -A | grep dm

Hi,

As logging in as a different user worked, I tried to change permissions recursively of \home folder to default.

It seems that some config files was with read/write permission only for the owner and the rest was set as forbidden.
So now I think the problem is solved.

Thank you all :slight_smile:
