[Bug 300496] New: X uses 100% CPU when using the "intel" xorg driver and the Xen kernel
https://bugzilla.novell.com/show_bug.cgi?id=300496 Summary: X uses 100% CPU when using the "intel" xorg driver and the Xen kernel Product: openSUSE 10.3 Version: Beta 1 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Xen AssignedTo: cgriffin@novell.com ReportedBy: jfunk@funktronics.ca QAContact: qa@suse.de Found By: --- If I boot the Xen kernel, X, with the intel driver, uses 100% cpu and hangs. The cursor still moves, but very slowly. Everything works fine with the default kernel. Unfortunately, there's nothing obvious in the /var/log/Xorg.0.log, but I will attach it anyway, along with the output of hwinfo. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It seems not to be an X problem. The following works: Booting into runlevel 3, login as root, then X & sleep 3 ; DISPLAY=:0 gnome &
No longer authentication is used.
I have a perfect X session without problems. I assume there is a problem withing the session management. Neither startx, nor gdm, nor xdm work.
See my comment above. See also comments #22-24. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I suggest to install all xorg-x11*debuginfo packages, attach gdb to Xorg process (started by startx/gdm/xdm to make sure authentication is in use) and start the sample X11 program. Or start the sample X11 program in gdb first to see where it hangs.
