 Posted: Thu Mar 10, 2005 9:31 pm Post subject: ATI drivers ignoring my modelines... [SOLVED] |
 |
|
First, yes, I searched the forums, but comparable problems were not solved in any way 
I've got an Acer Aspire LMi 1501 notebook, which has a Radeon Mobile 9600 (M10) built-in. Gentoo's running fine on it, also Xorg and ATI drivers. But there's still one problem which bothers me since I first used the proprietary ATI drivers. The laptop has an LCD panel with a native resolution of 1400x1050 (SXGA), but sometimes I want to use a lower resolution, e.g. 800x600. I created modelines for every resolution I possibly want to use, but fglrx refuses to use them except for the 1400x1050 native mode line. Xorg.log says:
| Code: | (II) fglrx(0):

I think the problem is that fglrx is "using on-chip RMX" to determine my panel's native resolution. Because it's an LCD display, it naturally just has one native resolution, but it could display other modes (centered or interpolated, I think the "CenterMode" option controls this). Now, my question is: how do I tell fglrx NOT to use this "on-chip RMX", but instead my modelines?
Here's my Xorg.conf (just the display sections):

Aren't the modes usually listed separately? Eg: | Code: | | Modes "1400x1050" "1280x1024" "1280x960" ... |
Might be worth checking if that makes a difference, because it looks like it's treating all of those as a single mode from your log.
