Kubuntu 16.04 and Intel Graphics
I have updated my Kubuntu freom 15.04 to 15.10 and finally 16.04. Althoug most of the process went smoothly I encountered some snags, that needed tweaking.
Breeze and Intel graphics do not like to play along
Wehen being presented with the login screen and entering username and password, the fields got grayed out but nothing else happened. So I switched to another console (Ctrl-Alt-F1) to check put what’s happening. As it turned out, switching back to the X-screen (Alt-F7) magically had solved the problem and I was presented with my usual desktop.
After googling around I found some bugs involving Breeze (the thing that manages and displays the splash screen) and Nvidia cards and one here having to do with the acceleration mode. Building on that, I followed the instructions here and that solved the problem.
For completeness:
I created /etc/X11/sorg.conf and added those lines:
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection
Control Panel Over/Under broken on Login
I like to have my KDE Control Panel on the left hand edge of the screen, with no overlap with windows whatsoever. Unfortunately this setting was lost on each and every new login.
The solution was to install the KDE Backports for Xenial Xerus as described here.
