I did a clean reinstall of Ubuntu 9.10 32-bit on the same machine. On the tenth reboot (after setting up stuff), gdm started to crash again, meaning this issue has nothing to do with 32-bit or 64-bit. No particular action before last reboot before crash that I can correlate to gdm crashing.

Same problem here. Karmic 32 bit, nvidia-185, gdm 2.28.1 and massive crashes at gdm starts.
Starting by hand (startx/startxfce) works nicely. Compositing is working perfectly. Seems to be gdm specific.
(dual screen config in case if it matters)

Same problem here, but

VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]

and Karmic 32 bit.
GDM crashes but startx ist still working.

After karmic to lucid upgrade, I have the same bug. startx and kdm are working fine. Changed my card from nvidia to ATI and get the same problem.

[Håvard Berland (berland)]

Bug confirmed for Lucid here as well. kdm workaround works. Immediate symptoms are changed in that you now get a message that Ubuntu is booting in low resolution instead of an all black screen (but I cannot get into a desktop nevertheless).

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version.Thanks in advance.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
