Gutsy Herd 3: Login hangs in a loop

[Kai Springer]

When I try to start the Herd 3 live cd my system gets stuck in a loop while trying to login. First the kind of brownish screen appears, then the mouse hangs and after while xorg restarts. Then a login appears and tells me that the user "Ubuntu" will be logged in 30 secs. Afterwards the same process begins again and again until I restart the machine.

I got a Benq Joybook R22E:
AMD Athlon XP 2800+
512 MB Main Memory
Via Unichrome IGP Pro Rev. 01 on K8M800 Northbridge

Hope that helps.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description didn't include enough information.

Please include the information requested from [WWW] https://help.ubuntu.com/community/DebuggingXAutoconfiguration as separate attachments.

I'm seeing the same behaviour on Tribe 5 of Gutsy, except for the login speaking about the user 'Ubuntu'. I'm running a Fujitsu-Siemens Amilo A1650G:
Chipset: ATI RS480 + ATI SB400
CPU: Mobile AMD Athlon™ 64 3200+
1 GB ram
Graphics: ATI Mobility Radeon Xpress 200g
All specs available at: http://www.fujitsu-siemens.com/Resources/13/225690970.pdf
(Feisty working perfectly)

So basically it is an infinite loop alternating between the default ubuntu brown colour with a movable mouse, freezed mouse on the same screen, black screen, the ubuntu desktop wallpaper, the Gnome menus flashing breifly and then back to the brown colour or black screen. Ctrl-Alt-Backspace does not work, neither does anything else. When the Gnome menus appear they are clickable for a second or so until they disappear again. Switching to another tty doesn't work either.

The information asked for on https://help.ubuntu.com/community/DebuggingXAutoconfiguration is not possible to give since I cannot reach a command prompt to do anything. Ubuntu doesn't respond to anything during this "process".

Marking as dupe of 132207 rather than vice-versa since its comments have a bit better analysis of the issue.
