The XOrg log shows an error relating to the drm module[2]. At this point, if I close the "low graphics mode" dialog and restart lightdm, everything comes up properly. What's interesting is that if I pass "break=mount" to the kernel and boot into the busybox shell, and then exit the busybox shell without changing anything, X loads the desktop perfectly. I have tried: * Different machines. I get exactly the same result across three different machines running different graphics hardware (intel, nvidia, ati). * Different ISO images (precise daily live CD, precise release DVD, and quantal daily live CD). * Putting the graphics driver modules into the CD initrd, so they're loaded earlier in the boot sequence, all with no effect.
