After what must be a recent update (since yesterday), my X resolution had dropped drastically. It's normally around 1200x1024, today it must be 640x480 or 800x600. I have no xorg.conf file, never had. The graphical config utility does not list any usable resolutions, system-config-display launched from vt1 does. I do not want to use an xorg.conf file, I like using automatic detection. Radeon 9100 Iiyama ProLite E2200WS-B1U xorg-x11-server-common-1.4.99.905-1.20080701.fc9.i386
