Thanks for the bug report. You seem to be using an unsupported kernel AND have unsupported Mesa packages installed from a PPA. So it's unsurprising that rotation and hardware acceleration might not work.
If you don't know how to fix this yourself then please just reinstall Ubuntu, and avoid installing PPAs or custom kernels in future. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958852 Title: Auto-rotation does not work anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1958852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
