Linux screen resolution problem


Hello world....


i got an ATI Rage 128 graphics card, Linux decided to use the "r128" driver with it (which is the corrrect 1 and working fine)

the problem is,,, I know my graphics card can display very high scren resolutions, ive read up on the r128 driver, and know it can also support very high screen resoulutions,, But i cannot get any resolution other that 800x600.

First i tried the Graphical tool, after changing the resolution, it told me to restart the X-server, so i did, and the resolution had set itself back to 800x600.

SO, i opened up my
/etc/X11/XF86Config file, and found a line under the screen part that gave only 2 resolutions

"800x600" "600xwhatever"

and changed it so that it also contained the resolution i wanted,

NOW, when i set this resoultion, and restarted X, the OS said that it was displaying my desired resolution, but obviously was not,

SO again i edited my XF86Config, so that the only available resolution was the 1 i wanted, but this time on rebooting, i get a "0 height not big enough, blah blah blah must be atleast 128"

GRRRR, i know the driver is capable of displaying the desired resolution, and i know the card is capable, and i know my monitor is capable, WHY WILL IT NOT LET ME DO IT !!!!

With this tiny resolution, i cant use KDE properly, as in many windows, the Ok, cancel apply buttons are off the bottom of the screen, also, everything is so damn HUGE and ugly,

thanX for any help.

GRRRRR.

ThanX for any help... if it is important, im using RedHat 9, with the KDE desktop.

all stuff is up to date, thanX

you can use redhat-config-xf86 but make sure u choose the correct setting for your monitor cause when redhat probes my screen i get only 800x600 but when i choose my monitor from the list i get 1024x768 resolution

I have no idea what my monitor type is, got it second hand, and has no company name written on it, all i know is how it works under windows

runlevel 3 ??? sorry, im new to linux.

and i tried executing XConfigurator in the command line, but get Bash: unknown command error's

But thanX for all your reply's, this problem has been bugging me since i got linux, (4 days ago) lol.

Just use the Redhat resolution config utility (in the menus,look for display settings or something). Choose a standard screen type if you don't know what yours is, or enter the refresh rates from the manual

Thanx for all the help.
it turns out ive got some kind of stupid monitor, that rejects all attempts to alter screen resolution unless the perfect horizontal and vertical scan rates are perfect.

linux had probed it and set a value of sumthing like 49.99999999

after i rounded it up to exactly 50, the monitor started cooperating.

thanx for the help.
