Newbie with laptop resolution prob

pulsersc78 · 09-17-2006, 04:47 AM

Hi I am a newbie to linux. I installed fedora core 5 on my R51 laptop. It detected the Mobility Radeon card but nothing for the screen. Right now its 800x600 resolution and if I put it to 1024x768(which it can very well support) it goes wonky. Can anyone give me a ste-by-step way of solving this?

My laptop(compaq) has the Radeon Mobility. I had to add two lines to the Section "Monitor" section of xorg.conf

Code:

Section "Monitor"
   HorizSync  31.5 - 48.5
   VertRefresh 40-70
EndSection

I can't guarentee it will help, and I don't know if it will have a negative effect on your laptop screen.

Next question where do I go to edit that file?

*Edit*
Nevermind found the file in /etc/x11

Those values are already set though

The file is in

/etc/X11/xorg.conf

and editing it happens using any text editor, either in command line (pico, nano, vi, joe, emacs, ...) or in X (gedit, kate, ...). Though after you've edited that you need to restart your X server for the changes to take effect. This happens most easily by pressing the key combination ctrl+alt+backscape. Rebooting does the same, but it's easier to just restart X.

Not sure how to use those editors but it's ok. I logged in as root and the resolution was 1024x768 (woot!). So then I logged back in as user and when I changed the resolution under Screen Resolution option it actually worked without going messed up. Lucky me I guess :P

Thanks for all the replies guys.
