I'm seeing the same thing after upgrading from 8.04 to 8.10, with a dual monitor setup and Xinerama. I have this in one of the Device sections in my xorg.conf:
Option "RandRRotation" "true" Option "Rotate" "left" Because at one time that's how I finally got rotation to work on one of my monitors and continues to work today. Everything appears to be working just fine, but the same with that error message when I launch GUI programs from the command line. I'm using the proprietary nvidia driver 96.43.11. Not a huge problem, just thought I'd throw my $0.02 in. -- w/ Xinerama enabled, Xlib displays RANDR warning dialog https://bugs.launchpad.net/bugs/295313 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
