Description Saulo Toledo 2010-09-27 01:49:38 UTC

Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

This happened at any KDE version I tested here.
I have an EEE PC 1005 HA (Netbook). When using KDE, any application, my window go to gray and I need use the shortcuts to Hibernate and return the PC again, or I never see my window again.

But this is a bad problem: I lost my internet connection, my downloads, my copying operations.... and this happens frequently! And don't have time to happen, can be now, can be in 10 minutes or 1 hour...

If I use another monitor connected at my netbook, the other monitor don't go to gray, only the EEE PC window (see, I'm was testing another monitor here, and if this happened when I'm was trying presents something at work or client?

Reproducible: Always

Steps to Reproduce:
It's frequentily, but I'm unable to reproduce, simple happens...

a) is this related to compositing? (press shift+alt+f12 to suspend/resume it)
b) do only (several) windows go "gray" or the entire screen?
c) does "gray" mean "black", ie. does the screen simply turn off for power savings?
d) do you still see the mouse pointer?

The shortcut do not worked here... I think I don't understood exactily... But my compositing is disabled here, I need some more memory and processing at netbook.

b) do only (several) windows go "gray" or the entire screen?

Entire screen.

c) does "gray" mean "black", ie. does the screen simply turn off for power
savings?

No, it's gray. The netbook do not poweroff. Then I use Fn+F1 (shortcut to Sleep him) and here the window goes black (power off the screen). Then I press some shortcut and the window is back.

d) do you still see the mouse pointer?

No.

sorry to say, but w/o compositing KWin is not invoked into the painting process.
Since not only single clients are affected, but also the pointer is gone this is a bug in either
- the kernel (linux)
- X11
- your gpu driver
- your hardware (ewww...)

, sorry

(you should check whether debian already uses KMS. could be the source... *shrug*)

After some upgrades since the report, the bug isn't an issue anymore.
Thanks for your time.
