Thanks for your detailed investigation. I think the main problem is incorrect virtual size with panel. When the second monitor is connected, then virtual size is taken from external monitor and X runs perfectly.
You said that after add checkpoints, the X have started correctly (some timing issue?). Could you please check which exactly checkpoint is needed to run X correctly? -- [K8M800] mouse pointer corruptly displayed at the bottom of the X screen https://bugs.launchpad.net/bugs/386740 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
