Description Bohan 2007-11-12 00:26:51 EST
Description of problem:

Hibernation results in black screen with blinking cursor in Gnome, while 
attempting to hibernate in kde results in an error message. 

Version-Release number of selected component (if applicable):

0.7.x SVN

How reproducible:

Always

Steps to Reproduce:

1. Install f8, kde and gnome on a nForce 4 mainboard with GeForce 7100 PCIE 
2. hibernate in gnome.
3. hibernate in kde with kpowersave tray icon -> error message
  
Actual results:

error message in KDE:

Title: Error while prepare Suspend to Disk - KPowersave

MsgText:

Could not umount external media before suspend/standby. (Reason: Could not 
call DCOP interface to umount external media.) Would you like to continue 
suspend/standby anyway? (Warning: Continue suspend can cause data loss!)

Buttons: Suspend anyway (black screen, data corruption) or Cancel

in Gnome:

Black screen, filesystems not umounted, orphaned inodes on /home parition 
reported by fsck on next boot

Expected results:

hibernates (dumps RAM to image on swap partition, then powers off)

Additional info:

logging out of X then running '/sbin/pm-hibernate true' does the same thing, 
though there is less risk of data corruption.

Tried vesa, nv and nvidia (from livna) drivers for X, no difference.

Not really a kde bug, but...

afaik, Nvidia (nv X driver in particular) is known to not hibernate properly, so
hal purposely disables the ability to do so.
