Since yesterday my window managers don't load completely. There are no window controls or any panels visible. Cinnamon for examplem goes straight to fallback mode; Unity doesn't throw an error but has no panels as well. Programms, even with gui, work if I open them from the terminal.
Here is my .xsession-errors file content as I have the feeling it could have something to do with this: http://pastebin.com/wh4pmcPe
Do you have any idea what could help?
I already tried:
- switch to nvidia-355 driver (instead of 358)
- write a new xconfig-file (had this issue before)
- reinstall the kernel 4.2.0-22
- boot using kernel 4.2.0-21
- fix broken packages with "apt-get -f install", nothing found
- apt-get install --reinstall xorg
I have no idea what to try next. My try probably would be to reinstall Ubuntu after a backup.
New testing results: this has to do with my user account!
I created a new user and everything is working fine if I log in with this new account. What could cause this issue in my settings? What could I delete to force new configurations?
Thank you in advance! Have a nice New Year's Eve and a lucky 2016!
