Created attachment 32310 [details] Xorg.0.log from no xorg.conf start ATI Technologies Inc RV515 [Radeon X1300] Fedora 12 with latest updates. X.Org X Server 1.7.1 Release Date: 2009-10-23 X Protocol Version 11, Revision 0 Build Operating System: 2.6.18-164.2.1.el5 Current Operating System: 2.6.31.6-166.fc12.i686.PAE Build ID: xorg-x11-server 1.7.1-7.fc12 Module ati: compiled for 1.7.1, module version = 6.12.99 Module radeon: compiled for 1.7.1, module version = 6.12.99 Monitor is capable of 1920x1200 60Hz, as per documentation. And this machine originally ran Windows and was able to drive the monitor at full resolution. I installed Fedora 12 on this box, and it is unable to do better than 1680x1050 60Hz. Attached is the Xorg.0.log from the no xorg.conf run.
Kernel has to boot with nomodeset. Without the nomodeset the DVI port is black. With monitors on both port VGA (monitor can do 1600x1200) and one on DVI port (monitor can do 1920x1200 x 60hz). Initial startup into text mode, both monitors show mirrored text. Starting X via startx, VGA monitor shows desktop, DVI monitor shows black screen. Desktop thinks it streaches across both monitors.
