[G45] [Jaunty alpha3]Compiz issue: change to higher resolution cause distorted screen

[Shaohua]

HW :McCreacy(Desktop)
OS :Jaunty(9.04)_Alpha3_X64

System environment:
-- chipset : McCreacy( Intel Corporation 4 Series Chipset DRAM Controller (rev 03))
-- system architecture : x86_64
-- xf86-video-intel : 2:2.5.1-1ubuntu7
-- xserver : Xorg 1.5.99.3
-- kernel :2.6.28-4-generic
-- Linux distribution :ubuntu-Jaunty-9.04-amd64(alpha3)
-- Machine or mobo model :Intel Desktop-McCreacy
-- Display connector :VGA

Steps to reproduce:

1:OS boot with Compiz launthing :System-->Perferences-->Appearance--->Visual Effects-->Normal(default).
2:set lower resolution "800*600" by GUI mode---"gnome-display-properity".
3:set higher resolution "1152*864" by GUI mode---"gnome-display-properity".
4:repeat step2,step3 3 times.
5:It would induce three quarters screen disorder.

I have the same problem. I cannot move the windows in a part of the screen (the new one). It is related to compiz cause metacity does not have the same behaviour.

[Aaron Roydhouse (aaron-roydhouse)]

There are similar bug reports like this one for 8.04, and 8.10, e.g. #249790.

The common thread appears to be compiz on an Intel card (so presumably Intel X server). It could affect other combinations but the reports I've seen have all been on Intel cards.

If *increasing* the resolution, compiz doesn't notice it, doesn't adjust or redraw the screen. Workaround is to restart compiz after the change ('compiz --replace'), or switch to metacity when making the change.

If *decreasing* the resolution, compiz+X frequently - but not always - crashes and logs you out. The workaround is to switch to metacity while reducing the resolution, then switch back to compiz.

[Aaron Roydhouse (aaron-roydhouse)]

Not sure if this is the same thing but ATI users appear to be reporting similar problems with compiz and resolution changes in both 8.04 Hardy and 8.10 Intrepid, see #206998 and #205085. Again is these cases, switching to metacity makes the problems go away. Not surprisingly, patches to xrandr are implicated; so it might be versions of xrandr+compiz that is the root bad combination rather than the particular X server.

[Aaron Roydhouse (aaron-roydhouse)]

Found a collection of bug reports (#132065 and duplicates) going way back where compiz also doesn't react if xrandr is use to rotate a screen (e.g. for tablets). Again restarting compiz corrects things. Again metacity notices the change and automatically adjusts.

Does this mean compiz is where a fix is needed? Since the problem always involve compiz, occurs across multiple X servers, and since other windows managers (metacity) play fine with xrandr?

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:

  http://cdimages.ubuntu.com/releases/karmic/

If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as
well.

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.

[Bryce Harrington (bryce)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

I have similiar problem
dist: karmic
pkg: latest intel
device: Intel GMA X4500MHD (I'm not sure with MHD :-D)

only if I change lower res to upper (e.g. 800x600 to 1680x1050)

KMS enabled

I've already switched to Karmic and that problem no longer exists. It seems as though the Intel / Compiz issue seems resolved as far as I can see. I'm going to switch to Lucid, however as the USB transfer issue has been unresolved since Jaunty.
