Bug 493328

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf, if available) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Now that I updated the system, I can't reproduce the bug anymore. I will try to inform you if the bug appears later.

I'll send the Xorg log anyway, though, just in case it is useful anyway.

Can you try fedora 12 livecd ? I think this bug is now fixed.

Fedora 12 beta screenshot with Compiz

I observe the same effect on Fedora 11 -- display artifacts around the menus.  I am using an ATI Radeom 7500.  Unfortunately, unlike Joonas, my system still displays the artifacts even after I apply all F11 updates.  I have attached an Xorg.0.log for F11.

I then installed the Fedora 12 beta, and things seem even worse there.  Compiz does not work at all.  Specifically, all window titlebars disappear and none of the window manager functionality works.  The desktop effects don't show up either (in F11, they did show up, even with the display artifacts).  Screenshot and Xorg.0.log have also been attached.

Neither installation has an xorg.conf file.

Fedora 12 screenshot with nomodeset+XAA

Ok, I conducted some more experiments.  Most of this follows the recommendations in https://fedoraproject.org/wiki/Common_F11_bugs

In both Fedora 11 and Fedora 12 beta, adding "nomodeset" to disable KMS results in Compiz working, however the desktop background becomes black and the nautilus folder icons are inaccessible.

If I add Option "AccelMethod" "XAA" to xorg.conf in addition to disabling KMS, then Compiz works correctly in Fedora 11, and there are no problems with the desktop background or icons.  However, the desktop effects are slow (I cannot quantify this, but it seems slower than on other distributions, with the same hardware).

In Fedora 12 (beta), if I use XAA and nomodeset, Compiz mostly works, except for the occasional appearance of display artifacts near the top of the screen.  I have attached a screenshot showing what I mean.  The artifacts are not as bad as the original menu artifacts, because they go away if you move or refresh the window.

Seeing as how this bug applies to both Fedora 11 and 12, is there any way to change the version number in the bug summary?

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command

yum upgrade --enablerepo='*-updates-testing'

Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD .

Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.

If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.

In reply to the automated message, I have already described above that this bug still exists in F12 (although the details differ).

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Please attach full dmesg when on Fedora 12 with KMS enabled after the bug did occur thanks.

Fedora 12 dmesg output with KMS

As requested, here is the dmesg output for Fedora 12 on boot with the default (i.e. KMS) settings.

can you try with the latest -ati and mesa installed?

http://kojipkgs.fedoraproject.org/packages/<name>/

Thanks,

Compiz with KMS works perfectly and at normal speed on F12 with the latest xorg-x11-drv-ati and mesa-{dri-drivers,libGL,libGLU} packages from koji. Specifically,

xorg-x11-drv-ati-6.13.0-0.15.20091127gita8dbf7c23.fc12.i686
mesa-dri-drivers-7.6-0.17.fc12.i686
mesa-libGL-7.6-0.17.fc12.i686
mesa-libGLU-7.6-0.17.fc12.i686
glx-utils-7.6-0.17.fc12.i686

With KMS turned off, compiz works, but is very slow, and the desktop background is black (and does not change, no matter what you set it to be).

The combination of nomodeset + XAA leads to the same display artifacts as in my screenshot of 2009-11-03.

However, again, using the latest packages above, Compiz together with KMS works perfectly, so I don't see any particular need to worry about the situation without KMS.

Ok closing this bug reopen if you see this issue again with KMS.
