I did few package upgrades (can't find the log) via gslapt (using the GUI) and after rebooting at the logon screen mouse and keyboard no longer work, and the screen resolution has lowered, althoug you can still see the login fields! weired.
Using SysRescCD choosing "Boot to an existing linux distribution..." I managed to boot it and get the login screen where everything is as it's supposed to be

however after login there is no sound and also problem with playing some video files on internet. I would assume these would get fixed if I manage to do a proper/normal login (not using SysResCD).
Can someone please guide me to fix this?
