Bug Description
SW: Kubuntu Feisty (up-to-date)
HW: HP nw8240 with ATI FireGL V5000 PCIE (x700), 15.4" LCD (1920x1200, 145 DPI)
I update fesity daily, and after the update yesterday afternoon, my X does not start any more. After the boot, when I should get kdm login dialog, I just get blank screen.
When inspecting log file, it looks like that display is not detected any more. After adding sync ranges to the Monitor section, I got X back, but screen size was not detected properly, causing DPI to be set to 75 (instead of 145), making fonts really small. I have fixed this with adding DisplaySize in monitor section. These are all the changes I had to do:

I have looked what have changed recently and it seems to me that recent update of ati driver for bug 22985 might have caused that.
Note: I was one of the reporters of that bug, but it was fixed for me just before Edgy release: https:/
