I'm aware that others have had a similar problem, but I've tried searching the forums and haven't yet found something that seemed to work well, so I'll try posting the details of my situation and maybe that'll help.

I had Dapper installed on a USB external hard drive for my Dell Inspiron 5150 that uses an ATI Mobility Radeon 9000. I got the laptop in late July 2003.

I didn't have any graphics problems while I was using Dapper, but I wanted to try Hardy, so I used the upgrade (which took a few hours to complete). I'd had this "black screen when trying to log-in" problem when I installed Gutsy on the internal hard drive, but I was hoping that I might be able to fix the problem with Hardy.

The problem appears whenever the bootup sequence tries to load gdm/X/login and display the login screen. The screen usually either fades to gray or just to black and quickly becomes unresponsive. I generally have to shut the computer down by pressing the power button. Oddly, I can still hear the usual log-in sounds from the speaker when I try to log in. Also, the splash screen itself seems to load and display without a problem, although I've tried disabling it (from the kernel boot line) to see if that would help (it didn't).

I'm not sure what the graphics differences are between Dapper and Gutsy/Hardy. I wonder if the visual effects are part of the problem.

I think I've heard that getting a different set of graphics drivers can help? I don't know if that's the best solution, though.

Here's my xorg.conf file:

I'd greatly appreciate any help that can be provided. It's possible that there's a closely related thread somewhere in the forums that I missed, although I tried pretty hard to find helpful threads.

Thanks for your help. If there's any other useful information that I can provide, just let me know.
