modeline ignored

steve_96 · 11-17-2006, 08:53 PM

I used to use a modeline that would shift the image on my monitor. I generated the line using xvidtune and put it in the monitor section of xorg.conf. With my current "radeon" driver in FC6 this line seems to be ignored or at least overridden. My Xorg log shows lots of activity, apparently related to picking a good modeline to use. Unfortunately it's not the one I want.

Can you post your Xorg.conf please?

Thanks for reply. The problem computer is at work, I tried to SSH to it but couldn't find the address. Will post xorg.conf tomorrow -- about 20 hours from now.

The default xorg.conf created with radeon driver didn't have a "Monitor" section. I added one with Identifier and Modeline lines. Also added "Monitor0" to "Screen" section. That didn't work so I added HorizSync, VertRefresh, and Option "dpms" lines (shots in dark as I don't know what any of these do). Still no go on shifting monitor image.

For background, this is what I'm trying to do: http://www.linuxquestions.org/questi...ad.php?t=96702

Here is my xorg.conf. I commented out the modeline because it doesn't seem to do anything.

Code:

I don't know how to configure the radeon driver outside of editing xorg.conf. Unfortunately, I don't really know how to to it there either. What I really want to do is just move the image on my LCD monitor 1/8 inches to the left so the scroll bar and close button are visible on a maximized window. My KVM switch seems to mess this up when I use the linux driver. Using the fglrx driver fixes this but causes other big problems with my Radeon 9250 graphics card.

What *big* problems? In any case have you tried with external controls of your monitor?

steve_96 · 11-20-2006, 07:03 PM

fglrx from livna brings up black screen unless I don't load "dri" (or maybe "glx") then desktop comes up but randomly freezes. At which point top shows some X process consuming 99 percent of cpu. Google - especially recent ubuntu forums - list several unresolved problems with fglrx drivers and graphics cards of my vintage. I'm waiting for these to clear up before I try again because I think it may be a driver bug.
External controls work, but when I use the KVM switch to access another computer it is now moved too far left. Other computer runs a primative proprietary OS with little configurability by user is this area.
