Need help getting LCD display right


I am running SuSE 8.2, and cannot use Sax2 to configure all of my hardware.

Currently my config file I am using for x windows in XF86Config-4.

I have an LCD display whose native resolution is 1280 x 1024 at 60 Hz. However, X windows insists on running at 75 Hz. Now, my monitor can handle this refresh rate fine, but it causes some bluring to run out of its native mode.

I do not know how to change the setting to have the appropriate screen size, frequencies, AND refresh rate.

I am sure some of you out there have LCD screens with the same native resolutions -- have you found a configuration that works I can peek at?

Thanks!

Hey, mate. Take a look at this:


http://wolven.com/export/azazel/XF86Config-4-azazel

Pay special attention to the section where it looks like this:


Section "Monitor"
Identifier "Dell19"
HorizSync 30-96
VertRefresh 50-160
EndSection


That's what you're looking for. If it's not there, you can add it in.

Tell me the model number of your monitor, and I'll see if I can get you the exact timings for it. The problem that you are experiencing is based on you not having the correct refresh rate, so good call on your troubleshooting.
:_)

I do have access to my settings, and have them (I assume) properly programmed (horizontal 31.5-81.1, vertical 56-75). These settings came from the monitor's manual

It is a NEC MultiSync 1760v

However, it still runs at refresh rate of 75; this is via xrandr.

I want to change my refresh rate to 60 -- that's what I need help with.

Try changing the VertRefresh to 59 - 61 and restart X.
You can see some added info by looking at your X log file in /var/log/...

Oh my looking in /var/log/XFree86.0 log yielded some interesting stuff.

I am using fglrxConfig instead of XFree86Config, owing to Radeon 9800 pro drivers.

I did NOT tell this program what monitor type I had (no place to enter it)....

Somehow it is set up for two monitors -- here is a snip:

Sorry for long snippet

The weird thing: it detected my monitor somehow (NEC 1760C multisync), and is listed as a "future video mode", whatever the hell that means. The important part is that is has listed the video mode I want!!! (1280 x 1024 at 60 Hz refresh).

I can post my XF86Config-4 file if you need -- how do I pick this resolution???

(I tried to vert refresh thing already, thanks for the tip though)

Ahem.

I figured it out...the tip was looking once more at the config file and the log file

I simply "uncommented" the line with the appropriate settings in for me in my config file in the module section.

Why the heck it didn't do that when I set it up, I dunoo

Thanks for the assistance guys!
