When I reboot my uncles laptop, from time to time (like 20-30% of the time) it will hang in boot on a black screen.
I still can enter into Ctrl-ALT-F1 but executing startx from there will result in another blackscreen (this time with disabled backlight). I could switch to the next console, but I'm unable to start the grafic UI.
After such an event I started the OS sucessfully and imediatly checked the system log for errors. This is what I found when searching for "error" in KSystemLog:

Do you think one of those messages could be the reason for the blackscreen? And what can I do about it?
