I installed Jaunty on a pretty old box (1.2 GHZ AMD, ATI 9550, 512MB ram.. ).
Everything went OK, installed printer, emesene, skype, radeon driver, ...
At the end, I copied all music/video files from the windows that was previously installed. OFC, all permissions were set (from NTFS). I can't be sure, but this may be relevant since problem started appearing just after system stopped responding in the middle of the file transfer.
System just randomly logs off. In middle of surfing with Firefox or with just terminal working on aptitude. Sometimes programs just closes with no message or whatsoever. Rarely, PC freezes.
I went through dmsg, xsession log and found nothing. I will paste those files if relevant. I also tried disabling screensaver, didn't help.
Does normal user have permission for killing programs and logging off? It may be some plain vanilla virus written by scriptkiddie.
Any idea is welcome, thanks.
EDIT: looks like that's how X crashes. I will be inspecting X logs.
