Re: Debian 8, KDE Lockup

[ATrudyjane]

I had the same problem starting up KDE with a new installation of Debian 
8 with gdm as the selected display manager. In addition to that, there 
where GUI error messages that would pop up and disappear, but only when 
switching between desktops. Replacing gdm with LightDM as the display 
manager, uninstalling KDE, and then re-installing KDE from the 
appropriate repository (stretch) solved those problems. Running a 2010 
Samsung laptop with 6G ram, nvidia optimus card. Never figured out what 
caused the problem.
