i just installed suse linux pro 9.2 on my machine.firstly i wanted to know how to change my monitor refresh rate to 85Hz.i went to the display options it shows only 60 Hz and no other option.Is it nessecary to install my ati radeon 9800 pro drivers in order to get 85 Hz refresh rate ?
if yes, i do not know which radeon drivers to install from the site.it has following options

XFree86 4.1
XFree86 4.2
XFree86 4.3
X org 6.8

my pc config is amd 2000+, 512 Mb ram
 
Basically, you need to have the exact, correct vertical and horizontal refresh frequencies for your monitor in your xorg.conf file. If it only gives you a 60hz option, but you know the monitor is capable of more, it meanse SuSE incorrectly detected your monitor settings. Google for the specs of your monitor, open up /etc/X11/xorg.conf, and go to the part that has the monitor settings, mine looks like this:

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 30-86
VertRefresh 50-150

Adjust your HorizSync and VertRefresh accordingly, then log out of X and then back in, and you should be able to choose the correct refresh rate.

As for the ATI drivers, SuSE 9.2 includes Xorg 6.8.1, so get the drivers for Xorg 6.8.
 
Let us know if that doesn't work, because there's something else to look at (to do with the graphics card) but it's a bit complex and I don't want to get into it if it's just an issue with the monitor settings :)

(BTW, I bet I'm the only other guy on this board of good ol' American boys who knows who Sachin Tendulkar is...:>)
 
my monitor is syncmaster 753s but it is not there in the list so i made linux detect 750s and now i get 85Hz refresh rate and 1024*768 resolution.Thanks.
also i am having lot of difficulties in installing my ati radeon 9800 pro drivers whenever i install them i get a blue screen saying x-server failed to load with distorted graphics.
 
What you might also try is just commenting out the VertRefresh and HorizSync lines. X has become quite adept at probing the right rates, more so than many tools that write config files for it.

(Even if it's working now, you might want to try. If it works, you never have to think about it again, while you now risk that the information won't be quite right for some other, higher resolution.)
