Description of problem: 915resolution sets wrong horizontal and vertical synchronization times if the Bios type is 2 or 3. I modified 915resolution to fix this problem. This occured for a Dell Dimension 3000 with integrated Intel graphics controller 865G, and using the video driver i810. I tried to set the video mode for 1440x900@60 Hz in xorg.conf as Modeline "1440x900" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync and the bios is patched using (/etc/rc.local): 915resolution 1440 900 16 1904 934 It is then possible to select this mode and the screen is clear. However, the screen is shifted by about 50 mm to the right which is too far for some monitors to adjust. (I use a Samsung 940BW monitor). Version-Release number of selected component (if applicable): 915resolution Version 0.5.2 and higher. How reproducible: Steps to Reproduce: 1. use Modeline "1440x900" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync in xorg.conf put 915resolution 1440 900 16 1904 934 and similar into /etc/rc.local reboot. 2. one needs a monitor capable of 1440x900 (widescreen) I used Samsung 940BW 3. Actual results: Image on the screen shifted far to the right, unadjustable. Expected results: crisp image and centered. Additional info: I have a patch for 915resolution.

0.5.3 was just built and released. Does it resolve your problems, by any chance?
Sorry didn't get to this. I'm still using my hacked915resolution. I'm a little hesitant to get into this right now as I'm quite busy with other stuff. However, I had a look at the source of the new version 5.3 just now and see that there are now actual timing calculations in the program replacing my hack by a clean new function gtf_timings() - That's great. At the moment I admit I don't even remember how to go back to using 915resolution. I want to use it when I upgrade to the soon coming FC7.
