[Bug 420924] Re: suspend resume fails in kubuntu

[hasi]

I see it on a Dell Latitude E6400 (Intel GMA 4500 graphics). I can
confirm that the problem does not occur when compositing is turned off.

One more observation: the problem seems to progress and get worse after
resume. Initially, I can use the keyboard and mouse to operate what's
left with some functionlity (clicking menus, for instance). However
after doing this for a little while, this doesn't work either, and the
UI freezes completely, to the extent that I can't even bring up a
terminal by doing Ctrl-Alt-F1. I saw this several times.

@Joe: 
If you can live without compositing, just switch off "Desktop Effects", and suspend might work in your case as well. If one wanted to make a fancier workaround, one could change the scripts executed before sleep and after resume to switch compositing off before sleeping and turn in on after resume. For me, compositing is really not that critical. I am happy to use KDE w/o compositing until (hopefully) someone more capable than me is able to find and fix the real problem.
