Hi,

yesterday i switch off my laptop and today morning when i wanted to start it up i discovered that i had a "blank screen".
I did SHIFT+ALT+F1 and in console, i'm able to log in and type startx

At this moment, i can see my GIS applet and my conky windows, however no taskbar from plasma 5 etc...

ALT+F2 works and i was able to run chrome to write this message as you can see.
It seems i have 2 issues:
1. starting X (and not founding my standard user)
2. KDE plasma 5

i tried to kill plasmashell and to restart it but there are some missing, undefined objects.... as you can see

Code: Select all

alain@NTB0001:~/.config$ sudo killall plasmashell
alain@NTB0001:~/.config$ sudo plasmashell &
