I also have these symptoms on my Inspiron 1100. When comparing X logs from a successful boot and one that came up blank, I noticed the following difference:
< (II) intel(0): Output VGA connected --- > (II) intel(0): Output VGA disconnected Note that nothing was connected to the VGA output in either case. (anybody know how to configure X so that it ignores the external monitor connector?) As an experiment, another time it came up blank I tried connecting an external monitor and the login screen appeared on the external monitor and I was able to log in! However, there were still problems such as no mouse pointer. I also discovered that it is possible to (eventually) get a virtual console on the laptop display by randomly banging on ctrl-alt-(F1-F6) until one appears. None of this has anything to do with the looping/vertical lines problem. I still observe that as reported in the bug. -- [i845g] Blank screen problem on login, logout, power savings mode, tty switch etc https://bugs.launchpad.net/bugs/578167 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
