It appears we've lost momentum on getting this bug solved, so I think we should proceed with the backup plan of blacklisting the chip from compiz and kms until we can verify a proper fix to it. For this bug report we'll focus on the compiz blacklisting.
** Summary changed: - [RV200] [lucid] xorg froze after disabled KMS and enabling compiz on ATI Radeon Mobility 7500 + Please blacklist ATI Radeon Mobility 7500 from compiz ** Package changed: xserver-xorg-video-ati (Ubuntu Lucid) => compiz (Ubuntu Lucid) ** Description changed: - Binary package hint: xorg + Please mark the Mobility 7500 (1002:4c57) blacklisted in compiz. In + lucid unfortunately there are some regressions in X for this particular + hardware. We're working with upstream to get them sorted out, but I'm + losing confidence that we'll have a patch in time for lucid. As a + workaround, until a fix is in hand, we need to blacklist the chip from + compiz which will help avoid some of the worst of the issues for now. - In trying workarounds for bug #507148 I disabled KMS by booting with - radeon.modeset=0. I had compiz disabled, then enabled it. I had screen - garbling so tried to take a screenshot. This worked but after double - clicking on the Screenshot.png on my desktop, X froze. I could ssh in, - so I ran 'ubuntu-bug xorg' from there. I do not have an xorg.conf file. + [Original Report] + In trying workarounds for bug #507148 I disabled KMS by booting with radeon.modeset=0.
