update after upgrading to lucid: KMS is now getting turned on automatically (I can see it in my dmesg output), and so the bug is fixed from the standpoint that I no longer get a black background and no full screen apps. I do still get artifacts, but so far (a little less than a day) no freezes, so desktop effects are at least usable (before, i had a choice between black background or occasional freezes).
The other, larger problem, is that I now have horrible performance when scaling a video to fullscreen with desktop effects on. With desktop effects off, fullscreen video works, but video performance otherwise (most noticeably moving windows) is terrible. I do not believe I had this problem under karmic when I set both KMS and desktop effects on, but I never tested for it specifically. -- [RV100/RV200] (Needs KMS) Background and full screen apps don't show up when Normal Visual Effects on https://bugs.launchpad.net/bugs/444139 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
