So if you want to rely on KMS all you can do is update your kernel and hope that the issue has been fixed there. Rather up-to-date kernels RPMs for openSUSE are available via http://download.opensuse.org/repositories/Kernel:/HEAD/ If this doesn't help you can download, build and install the latest kernel sources from git (http://www.kernel.org/), which is a non-trivial task. Sorry, I can't help here. If the issue isn't there fixed either you can report the issue upstream on bugs.freedesktop.org according to http://intellinuxgraphics.org/how_to_report_bug.html You'll need to register for an account on bugs.freedesktop.org first, in case you don't have one yet. The easiest solution for now. Don't use KMS. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

KMS means that the modesetting is done by the kernel.

So you think that this problem is not related to X. Is there a possibility to change the resolution from console? I would like to start the Live-CD in runlevel 3 and check whether the problem also happens when X is not running at all.

...

all you can do is update your kernel

The Kernel shipped with 11.2RC-1 is quite up to date. There might be only little chance that this problem has changed in the meantime.

...

The easiest solution for now. Don't use KMS.

Exactly that is what I do currently with openSUSE 11.0. But I often use fast user switching which is quite slow with the old method. And sometimes (seldom) also here the graphics crashes after switching the screen resolution. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Mode switching is now done completely in kernel space, if you specifiy i915.modeset=1. As far as I know there is no tool to switch the mode on the console without running X. A bunch of fixes for KMS went into 2.6.32rc. In Factory we still have 2.6.31. So it's still worth a try. Just install one RPM and reboot your machine. We don't have KMS support in 11.0/11.1 at all. User switching means switching between several Xservers. In that case modes needs to be saved/restored, maybe even the graphics chip reinitialized. This takes some time. Is this any better when the kernel is doing that? Maybe. But obviously it's broken when you're trying to change the resolution. Would be interesting to see if changing the resolution works, if only one Xserver/Xsession is active. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

No, the probem is not reated to X. Mode switching is now done completely in kernel space, if you specifiy i915.modeset=1. As far as I know there is no tool to switch the mode on the console without running X.

I've discovered that the sources of the package "libdrm" contain a test program named "modetest". This tool can be found under /usr/src/packages/BUILD/libdrm/tests after installing and building the source package. With "modetest -s <resolution>" I can change the resolution and a test pattern is displayed. This works only from a virtual terminal (not under X), but a X server may although be running on another console. (When the test pattern is shown it's necessary to switch to another console and back in order to get the terminal back.) I've tried this several times with different resolutions without any failures. Under X I've tested again with "krandrtray" and also with "xrandr -s". The results are varying from time to time. Once I had three concurrent X sessions running with 3 different resolutions and there was no problem altering the settings multiple times (at least with xrandr). Another time already the first change (with only one X session) let my graphics crash (only parts of the desktop are visible, flickering, white screen, ...). Because of the varying results it's difficult to come to a clear conclusion. But without KMS (on my current 11.0 system) I'm suffering from similar problems (but not as often as with KMS). Any hints what to do next? How can I assign the problem clearly to X or the Kernel? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Thanks. Didn't know this.

Not really. :-(

Good question. Next question. :-( As already said, best would be to report it upstream. See comment #1. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
