Hallo Manfred, man kann im xorg.cfg-File den DDC-Support abschalten (siehe www.X.org), genauer kann ich es Dir aber nicht sagen, Du solltest in den Readme's ebendort nachsehen. Leider leider wird SuSE immer mehr wie M$, wehe dem, der es besser weis als das System zu wissen meint ....
- suse-xfree86 is an english speaking list (unless you wanted to reply privately, of course) - I don't know what SuSE is involved with this 'problem', it exists with upstream Xorg as well, so what's your point
I am using Suse Professional 9.2. I'm trying to run an X Window display on a 37 inch flat screen monitor (Sharp LC-M3700) connected by DVI to a ATI Radeon 7000/VE graphics card.
It works, but not at the highest available resolution. According to the manual, the monitor can display 1366x768 pixels. It works perfectly using an 1024x768 resolution, for example.
- All options that can be used for specifying the monitor are documented (man xorg.conf, search for Monitor, you will need to specify HorizSync, VertRefresh, DisplaySize), those for overriding autodetect could be documented better (this is driver specific, man radeon, you need 'Option "NoDDC"'). You very well may have to add a Modeline for your unusual mode as well. I agree that we would need a better FAQ for Xorg. - Your problem is twofold: - Your monitor is lying to the graphics card This is a common problem (I don't know what's so damn hard to get information values right) and can only be overcome with a large database with the correct values. Appearantly, your monitor is not included. - 1366x768 is no Vesa standard mode You will have to specify a Modeline to tell the Xserver about the timings to use. There are a couple of possibilities, SaX2 can do this for you IIRC. You already tried some if I read you correctly.
If I use the desired resolution, the monitor simply displays "out of range". I've tried both sax2 (also with the --vesa switch with the desired resolution as a parameter) and playing around with XF86Config by hand, even trying different "Modelines".
1366x768 is no vesa mode, no chance.
One problem seems to be that the X Window System does not properly recognize the resolution of the screen.
In /var/log/Xorg.0.log I find a line
(II) RADEON(1): Panel size found from DDC: 1024x768
Please try a 'hwinfo --monitor' from runlevel 3 (!). If the monitor still says its maximum resolution is 1024x768, it is lying.
