Okay, I got my machine working properly, but I had to go back to a 12.04-based distro (I used Netrunner). Here's how to get things working, without the trial and error that I went through.
1. Install the OS. 2. Disable Desktop effects, and install all patches. 3. Add the Bumblebee and x-swat PPAs. You have to do this because the latest NVidia drivers aren't in the 12.04 repos. 4. apt-get install bumblebee bumblebee-nvidia. This adds the latest NVidia driver to your machine. Unfortunately, it also installs the problematic Mesa 9 libraries. We will fix this in the next step. It's also important that you have desktop effects turned off. If they're still on when you reboot, you'll get really bad system locks. Once this is installed, reboot. 5. Video is configured correctly, but will have all kinds of problems if you enable desktop effects. To get everything working properly, you need to downgrade to Mesa 8.0.4. The following command will do that: sudo apt-get install libglapi-mesa=8.0.4-0ubuntu0.1 libgl1-mesa- glx=8.0.4-0ubuntu0.1 ia32-libs=20090808ubuntu35 ia32-libs- multiarch:i386=20090808ubuntu35 libgl1-mesa-glx:i386=8.0.4-0ubuntu0.1 libglapi-mesa:i386=8.0.4-0ubuntu0.1 libglu1-mesa:i386=8.0.4-0ubuntu0.1 libgl1-mesa-dri=8.0.4-0ubuntu0.1 6. Reboot. When you log back in, hit Alt-Shift-F12 and test that desktop effects are working properly. If they are, you can enable them by default. 7. To prevent constant update notifications, I used ppa-purge to remove the x-swat PPA. 8. Add the kubuntu-backports PPA and install KDE 4.9.2, which is the same version of KDE that 12.10 has. You now have a working system! No package mess, and you're running basically the same software. Since this seems to be a KDE bug, I'm not all that hopeful for a fix here; I'm betting it'll take another KDE release. So for the time being, I'm staying on this set up until either this bug is marked as fixed or the one from KDE is marked as fixed and there's a new release available. I hope this helps somebody! -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1061073 Title: Desktop effects are slow and desktop corruption using mesa 9 To manage notifications about this bug go to: https://bugs.launchpad.net/kdebase-workspace/+bug/1061073/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
