Suse 10.2 i386

Hi,

I just switched to Open Suse 10.2 i386 from Mandriva Linux 2007. On Mandriva, it supported many video modes as well as a vast range of refresh rates that were compatible with my monitor. However, both Ubuntu and Suse are similar in that the only refresh rate they offer for all their video modes, and by that I mean resolutions, is 60 hz. Mandriva and my monitor both allowed me to view a 1152 or something resolution with a comfortable 75 hz. This 60 hz is hurting my eyes.

My graphics card is a AGP Ati Rage 128 (Pro or Ultra, I can't remember), it's 16 MB.

My monitor is a Mag Innovision DJ700.

I don't know what to do.

If anyone could help, I'd be very grateful.

Thanks.

I have the opposite problem. My LCD display won't display anything if the refresh rate isn't 60Hz, so when I startup a new distro it often displays nothing. I have to drag out an old CRT to see what is going on.

The file that controls all this is /etc/X11/xorg.conf, documented at length by the command man xorg.conf. I fixed one system by simply adding the following line. You may be able to do the same but specify 75.0Hz. You may need to change or comment out the VertRefresh entry if it doesn't include 75 in it's range.

Code:

Section "Monitor"
...
        Option      "TargetRefresh" "60.0Hz"
EndSection

As for resolution, look for the Modes lines in the "Screen" section. If your monitor supports it, just add "1152x864" in front of each Modes line (and maybe "1600x1200" and "1280x1024" also).

Another option is to run the xorgcfg or xorgconfig or similar. These commands generate a new xorg.conf file. Though they often don't do a good job.

Be sure to make a copy of your existing xorg.conf before experimenting.
