Just have them running, or using the virt-viewer and virt-manager to look at them as well? May be the same problem I'm having here: https://bugzilla.redhat.com/show_bug.cgi?id=541387 Many things would freeze my display, but virt-viewer seemed to provoke it much more frequently. I've now switched from radeon to radeonhd and disabled many video accelerations with options in the xorg.conf file and I haven't crashed in a long time. Here's the relevant bit of my xorg.conf: Section "Device" Identifier "Videocard0" Option "DRI" "off" Option "AccelMethod" "shadowfb" Option "NoRandr" Option "UnverifiedFeatures" "off" Driver "radeonhd" EndSection I also have to specify nomodeset on the kernel options in grub.conf. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
