Description of problem: KDE session is killed and X window system restarts when I switch to tty and stay there for few minutes. Version-Release number of selected component (if applicable): Fedora 11 How reproducible: Every time. Steps to Reproduce: 1. Login to KDE session. 2. Switch to tty (ALT + CTRL + F2) 3. Login to console. 4. Wait few minutes, X window system should restart Actual results: X window system restarts. Expected results: X window should perform normally after switch and login to tty Additional info: This only happens with KDE and intel driver. I have no such problems on laptop where I use nvidia graphics. Also problem not happens where there is only GNOME installed or both GNOME and KDE (gdm is used on for X window login)
