Had the same problem. My Acer TravelMate 662 laptop (Intel 855GM) refused to boot with Lucid. Adding boot option i915.modeset=1 fixed this problem.
Afterwards I was experiencing X crashes when playing videos with totem. Installing the mainline kernel 2.6.33.3 provided by Ubuntu finally fixed all my problems, even the X crashes: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33.3-lucid/ -- [i855] X doesn't start with kernel 2.6.32-21 unless passing i915.modeset=1 https://bugs.launchpad.net/bugs/566379 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
