Yes, the xdiagnose utility allows switching on drm debug messages (the first checkbox). You might also experiment with disabling vesafb but I'm doubtful that would do anything in this case. In addition to testing the .39-rc kernel, you can test Intel's experimental tree which we package for Ubuntu now for testers: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next-proposed/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
