The report 

Description of problem:

See attache file for details. 

Note I was not offered to report this through SELinux Gui however I was offered to turn off memory protection.

I left the laptop suspended ( closed the lid ) overnight and I think this is the cause for the gui not return after staying suspended for so long ( all I got was a black screen with the mouse pointer keyboard was responding and switching to tty2 work fine and switching back to tty1 ( desktop ) still gave me black screen with only the mouse pointer visible.. then again this all might be a xorg-x11-drv-ati issue note this only seems to happen when the laptop has been suspended for a long period of time..

There is an effort to remove the need for mmap_zero from vbetool.  For now set the boolean and see if suspend/resume works correctly.

Uhum it did return after a while with vbetool hogging the cpu. 

It's been running like that for quite a while now which makes one wonder if vbetool is looping..

Note GPU ATI M22 Mobility Radeon X300 and this with "nomodeset" redoing the test with KMS ON...
Comment 6 Matthew Garrett 2009-10-30 10:27:24 EDT
The supported suspend/resume configuration for intel, nvidia and radeon is with KMS enabled, at which point vbetool won't be run.
