Screen becomes blank when switching between X11 and console
Last modified: 2019-07-23 10:00:15 UTC
When switching to the console (Ctrl+Alt+F1) and switching back to X11 again, the screen gets blank and whatever is done afterwards, stays blank. This used to work perfectly woth earlier SUSE versions.

Please try again with the new driver on Beta4.
Same behaviour with beta4.

Egbert, any ideas?
Yeah, the Xserver crashed. Works for me on an ICH7 (i945). I don't have an i845.
At least we need the logfile /var/log/Xorg.0.log*
> At least we need the logfile /var/log/Xorg.0.log* I assume that I also need access to the machine. I know we had discussions about this with QA in the past. But without access to the machine I cannot get a clue where to look for a segfault. The log file doesn't contain this information.

You can have access to the machine, it's vogon. But as I also use this machine as workstation, please tell me (by phone or email or whatever) when you intend to test on this machine, so I can logout beforehand.
I will call you within the next few minutes. The Xserver appearantly didn't crash.
Meanwhile a fixed driver is available, a patch is *not*. :-( I think this is sth. for RC2.
What do you mean by 'fixed driver'? This has been available as a test version for quite a while. I don't see a patch in CVS yet. I notified Alan about the success and will ping him again later today if nothing has happened.
Ah. You've meant the binary-only test version by Alan. I thought you did build the driver.
Created attachment 48902 [details] The requested patch Attached is Alan's patch which fixes the problem. This contains some fixes for gamma correction also. Really only the second last hunk is related to the reported problem. Stefan, it's up to you what you do.
package with (complete) patch submitted now.
fixed for RC2.
We need to add one more little thing.
Created attachment 49172 [details] Patch on top of the last one This patch should prevent undesireable side effects when accel is disabled.
I've seen this, but I wonder about the other location in I830BIOSSwitchMode(). Isn't this the same problem? [...] /* Sync the engine before mode switch */ if (!pI830->noAccel) (*pI830->AccelInfoRec->Sync)(pScrn);
Good catch! Thanks!
