I have a video card that has the ATI Radeon 9250 chipset. I had connected it to an old Iiyama CRT monitor, but replaced it with a prolite e380s TFT. I could login, but fonts were much too large etc. Eventually I discovered that switching from the 'ati' driver to the 'vesa' driver solved this problem. This is probably not an optimal solution, but works for me (only using this machine for firefox/openoffice.org/etc.). Just wanted to share this information somewhere.. BTW, as the title of this thread says, I am running Kubuntu 7.10 with all the latest updates installed.
