WUXGA screen specifications

Question

Hi everybody,

I got a Inspiron 8600 with a WUXGA screen and a Radeon Mobility 9600 Pro. I've installed Mandrake Linux 9.2 and I'd like to know the constructor specifications of the WUXGA screen. The reason is that I can get only two valid resolutions (1920x1200 and 1600x1200), all the others don't work. Especially the games, Enemy Territory doesn't work (due to bad resolution), Quake3 and UT work great 'cause I can fix the resolution in the configuration file (but it's not very convenient).

For your information I'm using XFree 4.3 and the ATI driver v3.7.0.
So, here are some parts of my XF86Config-4:

Section "Monitor"
Identifier "Dell Flat Panel WXUGA"
HorizSync 31.5-110.0
VertRefresh 30.0-90.0
DisplaySize 330 210
Modeline "1920x12000" 162 1920 1984 2176 2480 1200 1201 1204 1250 +hsync +vsync
Option "DPMS"
EndSection

Section "Screen"
Identifier "Main Screen"
Device "ATI Radeon 9600 Pro"
Monitor "Dell Flat Panel WXUGA"
DefaultDepth 24

Subsection "Display"
Depth 24
Virtual 1920 1200
EndSubsection
EndSection

I'm forced to use the virtual mode because if I fix the modes, it doesn't work.

Any experiences are welcomed.

Thanks,
Micha

I don't have an answer to your problem, but I was wondering if you could help me out. I have the exact same card/screen, and so could you post the entire XF86 config file so I can use it for my computer? I'm having a really hard time getting X to work (and yes, I downloaded and installed the new drivers) but I must be picking the wrong options or something because it refuses to work for me. So a detailed explanation on how you got that original config file (mine looks nothing like that after running fglrxconfig) and then just posting it would be incredibly helpful to me. A 1920x1200 resolution is all I want, just as long as it's something.

have you tried doing an 'X -configure' to generate a basic config file? You shouldn't have to specify modelines or dot clocks or other stuff anymore - this should all be auto-detected now.

If it still doesn't work, post you XF86Config and /var/log/XFree86.0.log files to the xfree86 mailing list. Look at www.xfree86.org for details...

I tried X -configure but it fails. There is no interesting information in the XFree86.0.log file.
For the modelines, X doesn't seem to be able to detect them automaticaly (the problem seems to come from the screen). So I have to specify the modeline for the 1920x1200 mode to have a proper image (otherwise the image is not center on the screen).

I'm gonna give a look at the XFree86 mailing list.

Thanks,
Micha

For Banana Fusion, here is my XF86Config-4:

Note that only two resolutions work: 1920x1200 and 1600x1200. I tried a lot of modelines for the screen and they don't work. So I guess the problem comes from the ATI driver.

I'm still having trouble getting anything. It's complaining about not being able to load the flgrx module. Which reading the installation instructions it sounds like all I have to do is run the RPM and it'll install everything I need for me. Any idea what's wrong?

mi-k · Answer

Well, it's hard to tell since you don't give any information.
You need to install the kernel source before installing the ATI driver. Then install the ATI driver rpm and run fglrxconfig to configure your card. Restart X.
If it doesn't work, post your /etc/X11/XF86Config-4 and /var/log/XFree86.0.log files to see what happens.

I have been trying to install Mandrake 9.2, when I download the driver from ATI it gives me errors about conflicts with already installed drivers.  I had selected the ATI fglrx driver during mandrake setup, could this be causing the problem.
