GDM freezes system?

Before the problem appeared, I had recently switched from KDM to GDM and uninstalled a great deal of kubuntu-desktop. I used
dpkg-reconfigure gdm
to change display managers. The next day after shutting down my HP Pavillion Enterainment PC freezes at "Stopping system V runlevel compatability" or something similar.

I rebooted my Ubuntu system in recovery mode got to a shell prompt and again uninstalled KDM. that allowed me to get to a normal-ish prompt - normal except for the fact that I have lost the framebuffer. I was able to use
but once I used
dpkg-reconfigure gdm
and rebooted my system freezes at a different point. I now am able to write to you after I used
dpkg-reconfigure gdm
but then selecting lxdm (I try out lots of software).

The problems that I have noticed as of now include:
  1. There is no display manager that functions.
  2. The command line framebuffer is gone (text displays unnecessarily large).
  3. Unity (2D I think) uses an inferior display quality (lower resolution)
  4. There is no sound anymore.

I had similar issues with gdm, especially with gdm3. I suspect it has to do with gdm's starting scripts. I would suggest you try slim as your default display manager, and see if tthe problems you mentioned are still there. It's lightweight and I never had any problem with it. LXDM might also be a good choice in the future, but for now it seems to be on early stage of development, and most distributions don't even include it in their repositories.


freeze, gdm, gui, sound, unity
