Change Screen Resolution

ikw38 · 10-29-2003, 09:19 AM

Hi,
This is a very elementary question How do I change the resolution for RH9.
It is set @ 800X600 and I need it to go higger so I can see my desktop better.
Thanks

You probable want to change resolution of X:

/etc/X11/XFconfig => Screen section => Modes "1024x768" "800x600"

You need to edit/change the Modes line (first entry is used first, so in the above example 1024x768 is your default resolution.

course its possible you could press ctrl+alt++ or ctrl+alt+- to cycle through the modes you have set

Yep it is, but your default res will still be 'wrong' and you must have multiple modes defined in the modes line.

i hv ur problem before, and all guys here just asking u config the Xfree86, but i can tell u if u change the modes in xf86config,
it cant go back X, so u finally need to change back the modes.

the solution to solve this problem is to config ur monitor..
after i config my monitor it can display 1024x768.....
it quite different from windows system.....
it depends on ur monitor... instead of display card..

gd luck

i have changed the mode to "1024x768" "800x600" but the screen still display 800x600 even i type ctrl+alt+ + to change it,the higher resolution still 800x600.

my monitor remains unprobed and i cant find the model for my monitor in the monitor list,my monitor model is acer v551.

any suggestion?

use the cmd redhat-config-xfree86 and choose a generic monitor if still not working try these sites www.hardware.redhat.com/hcl , www.xfree.org and see what is mentioned. Last but not least www.tldp.org

you need to set vertical and horizontal refresh rates for your monitor
when you run xf86config you will eventually be given the option to set these
i recommend google searching your monitor specifactions
this is what i got from searching "acer v551 refresh":
Horizontal Frequency
30-54KHz
Vertical Frequency
50-120Hz
