Managed to solve the problem with getting a blank screen while loading gdm after upgrading a desktop from 6.10 Edgy to 7.04 Fesity Fawn. The desktop has a ATI 9600 graphics card and works fine on 6.10 Edgy, however after the upgrade to 7.04, it starts having this problem. I knew it’s something wrong with the Xorg like many others, after trying a few changes in the xorg.conf without success, I ran the autoconfig for Xorg and that fix the problem, the command is:

sudo dpkg-reconfigure xserver-xorg

What that basically did for me to finding the HorizSync and VertRefresh, most importantly it changes the driver from “ati” to “vesa“! Initially I thought the problem was just that it doesn’t have a correct sync value, however when I changed the driver back to ati it gave me a blank screen again. So will have to use the vesa driver for a while until the problem with Xorg is fixed. Anyway, after configuring your xorg.conf or ran the command above, restart gdm by:

sudo /etc/init.d/gdm restart

everything should be running :).
