Hi,

yesterday i did 2 upgrades of my computers from'ubuntu 17.04 to 17.10.

while my laptop had some issues with nvidia drivers...as usual... now it works great.

my concern is about my desktop comptuer where i use AMD graphic card R7 radeon.
upgrade was good but when i'm on the logging screen, i type my login name and password, KDE start as i see the "plasma 5 made by KDE" text...but kde returns me to login screen and display me error message that ksmserver could not start. please check installation.



i found no information on internet about this issue that could lead me to some solution.
any idea how to solve that?

thx
