Public bug reported: When booting ubuntu, once every while a dialog appears with the warning message 'the system is running in low graphics mode'. I haven't found the thing that triggers it, and the occurrence of this dialog is highly irregular. At other times it boots just fine.
When pressing OK on this warning message (which is typically hard to do, as the mouse is not immediately apparent; I have to move the mouse all over the place before a classic Xorg cross-type mouse finally appears on this dialog), I get another menu with a number of options. I choose the option 'run in low graphics mode for just one session' and press OK. the screen then flashes a couple of times, before a dialog appears that says something like 'wait until the display manager resets'. I press the OK button of this dialog and I end up with no graphical interface at all, just a standard shell prompt asking for password and login. After logging in, inspection by ps ax | grep gdm shows that gdm is nonetheless running. Subsequently, when I kill gdm and do sudo gdm, I end up with a working, high resolution, display manager. Why couldn't this happen just directly upon booting? I have a video of the flashing behaviour when choosing for the 'low graphics mode for just one session'. The video is here: http://transgenerational.zoo.cam.ac.uk/CIMG1547.AVI. It will remain there for 2 weeks, ask me if you want to have the video afterwards. In my opinion, when I choose the option 'run in low graphics mode for just one session', I should get low graphics mode regardless of the graphics card. Which is obviously possible given that the warning message itself appears on the screen in a dialog. If I am not mistaken, even for nvidia cards it should be possible to run something in very low resolution without 3d acceleration by default.
