ATI Radeon 9200 DVI output to Widescreen display
I'm trying to get Linux running on my HTPC. Slackware Linux, kernel 2.6.6, Radeon 9200 with the latest xorg in slackware-current.
First problem was trying to get the widescreen display working. It's native resolution is 1360 x 768, so i made a modeline and tried that, no working screen found. I also tried 1368 x 768 because in windows 1360 doesn't work (I read it was a limitation of the graphics card) but it wouldn't work either. So, I installed the ATI drivers, compiled and installed the modules, made a new config with fglrxconfig. Now, when I startx the screen just goes black. I think the problem is in these two lines: Quote:
So how do i set up xorg.conf/XF86Config to use the dvi display? |
Something else, When i startx I get the message:

To anyone that found this thread by searching:
It doesn't look like DVI works with ATI drivers atm (3.9). Works with the Radeon driver, but the frequency is too high so there's screen flicker. I went and bought a good analog monitor cable that will work. I don't really notice any difference (although it's only from memory, not a proper side by side test). If your using a high res LCD and need DVI, as far as i can tell, don't use ATI. Widescreen works too. I had a look at the settings from powerstrip that work in windows, and using this modeline guide came up with this: (like i said before the Fujitsu HD display is 1360 x 768, but graphics cards can't output that res (except matrox iirc), so the next best thing is 1368x768) In the monitor section of XF86Config or xorg.conf: Modeline "1368x768" 85.47 1368 1436 1548 1792 768 771 777 795 +HSync +VSync I had to chang some of the numbers to centre the image. I logged into X, ran xvidtune, moved the image, and changed the numbers in xorg.conf. |
