[ltp] X60s: Suspend to RAM - KDE v/s Gnome

[Atul Chitnis]

Weird situation:

I use KDE 3.5.6 on FC6 on my X60s (1702-4EA). kernel is 2.6.20-1.2944.fc6, 
2 GB RAM.

I have set the KDE battery applet to suspend to RAM if I close the lid, 
which it does correctly. But when I open the lid again, I dont get my 
display back.

Note - the display *is* there (or I think it is there), because using 
muscle memory, I can still make the machine do what I want (I have set 
alt-F2 to open konsole), but my screen is black (i.e. backlight is off). 
Network and sound and everything else works just fine - I can ssh into the 
resumed machine, for example, play music using mpeg321, etc.

Now for the longest time, I suspected that to be a kernel issue, but this 
evening, a friend of mine asked me to log into Gnome instead from the gdm 
scren, and test suspend from there. And suspend to RAM worked, and so did 
resume - display came back on again.

Back to KDE, and try it again - no go. Once the machine suspends to RAM 
under KDE, NOTHING I do (vbetool dpms on, xset dpms force on) will get the 
backlight back on, not even an X server restart, change to init level 5 to 
3 and back, switch to text console...

And it works everytime in gnome.

I hate to admit this (my friend is a gnome/evolution developer and went 
all "muhahahahahaha" on me), but the problem does appear to be KDE. And no 
- switching to gnome is not the answer I am seeking.

Anyone have a clue about this?

TIA

Atul
