Description MDB 2009-02-22 21:12:41 UTC

Version:           KWin: 4.2.00 (KDE 4.2.0) "release 102" (using KDE 4.2.0)
OS:                Linux
Installed from:    SuSE RPMs

Using kde 4.2 from openSUSE Factory release 102

This is happening on multiple machines x86_64 and i586. Both are using the proprietary NVIDIA driver 180-22.

1. Open any application, for instance konsole.
2. Screen goes black.
3. Mouse cursor can be seen and cursor changes to "I" when over location where konsole should be.

Basically, this seems to happen as soon as kwin needs to show a window. I will provide a backtrace.

Actually this is only (as far as I can tell) happening when konsole is launched. Here's a konsole bt. But, konsole seemed to still be working fine. I just couldn't see the screen.

Comment 3 lucas 2009-02-23 02:28:59 UTC

Please add the following to the ServerLayout section of your /etc/X11/xorg.conf:

Option "BackingStore" "False"

Comment 4 Marc Benstein 2009-02-24 17:21:46 UTC

Using Option "BackingStore" "False" did not help. The behavior is the same.
