I have just upgraded Centos 7.1x to 7.2.1511 (KDE) and have noticed the following:- 1) nvidia drivers 352.63 (the latest ex elrepo) are not compatible with the previous kernel 3.10.0-229.20.1 - they require kernel 3.10.0.327.3.1 that was installed with the upgrade to 7.2.1511. This means I can't boot into older kernels. 2) When I change the screen energy saving switch off time under Power Management, I get a warning as per screenshot. The screen does however go blank after 15 minutes. Can this be resolved in some configuration ?
Solved. .kde/share/config/powermanagementprofilesrc Removed the entry [AC][DimDisplay] and the line following it:- [AC][DimDisplay] idleTime=900000
