I experience a similar crash with intel video hardware. The following has happened for me on two systems, a Dell GX100 and a compaq of similar age.
1) Install using the alternate installer preseeded to pull in the following additional packages: ubuntu-restricted-extras edubuntu-desktop edubuntu-addon-kde edubuntu-addon-science edubuntu-addon-young scribus blender inkscape audacity dia-gnome kompozer stellarium avidemux freecol freeciv-client-gtk freemind thunderbird thunderbird-gnome-support openssh-server 2) Log in with the user created during the installation, and add two mroe users through the Users and Groups tool 3) Start the Login Window manager and click the security tab. 4) The graphical desktop disappears. 5) I manually restart gdm. 6) Whenever I try to login, gdm crashed and restarts. The messages repeated in dmesg are May 18 23:48:01 ubuntu kernel: [ 2670.037487] ^Idriver to use reclaim_buffers_idlelocked() instead.

I haven't seen the crash again, but I haven't used either computer for more than 15 minutes. I will attach files from the Compaq. ** Attachment added: "dmesg" http://launchpadlibrarian.net/14595153/dmesg -- gdm crash at first log in https://bugs.launchpad.net/bugs/216302 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
