Since you are using xorg-edgers I went ahead and uploaded a new kdebase- workspace there containing a fix for this. It's likely to be worked around in natty on the mesa side by reverting a commit since the KDE guys do not want to take the patch but I believe it is more correct to fix it on the kwin side.
http://quickgit.kde.org/?p=kde- workspace.git&a=blob&f=kwin/opengltest/opengltest.cpp On line 85 it says to assume direct rendering works if DRI2 is exposed in the GL renderer string. In mesa on intel, "Intel" can be used in place of the check for "GEM" since Intel is not in the GL renderer string for !DRI2. Intel only supports KMS/DRI2 and swrast would be used instead in the other cases which will not pass the check. The GEM portion that was checked previously was historically added to the string when KMS was used back when intel supported UMS, but that has not been the case for some time now which is why it was removed upstream. Attached is the patch I applied in the PPA cleaned up for distro use in case it's wanted ** Patch added: "lp753370-kdebase-workspace.patch" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/753370/+attachment/2057881/+files/lp753370-kdebase-workspace.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753370 Title: No Desktop Effects in Kubuntu 11.04 Beta1 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
