I have a strange problem with my new XFree installation. The computer here has a Sapphire Radeon 9600 card with VGA and DVI, and I got X up and running ok using the "radeon" driver (sax2 configured, with Suse 9.0, XFree 4.3.0.1). The monitor is an LCD, so I changed the cable from VGA to a DVI cable. This was no problem on the console and for the "other OS", but for X. startx and Sax2 now both end up with a monitor showing "No Signal Found" and I have to use crtl-alt-backspace to end this. The X logfile shows no error. The only way to get a working X with the DVI cable is by using the vesa driver instead of radeon in XF86Config [...]

After lots of fiddling with various options I finally found out that the Suse radeon driver has some more options than the original xfree 4.3 radeon driver. This did the trick for me:

[...] Section "Device" BoardName "RV350 AP" BusID "1:0:0" Driver "radeon" ##### Option "MonitorLayout" "TMDS,NONE" ##### Identifier "Device[0]" VendorName "ATI" EndSection [...]
