I can't set the resolution higher than 1024x768
 
I've just installed slackware 10... but no matter what I try, i can't seem to set the resolution higher than 1024x768, it's really annoying. I know that my hardware is capable of that setting because I had my resolution set to 1400x1000(roughly) when i was using redhat 9.

Some hardware specs:

I have an ati radeon 7200 (that's what redhat used to detect it as anyway)
my monitor is a compaq S710

Can anybody help? Thanks in advance.

Take a look at your log file (probably /var/log/XFree86.0.log).

First, look at all lines that contain the string "768" for a possible explanation of why your system is defaulting to this resolution.

Second, look at all lines that contain the string "1400" (assuming you are trying to set a resolution of 1400x1000).

If you don't see anything from that, a line by line examination is called for. You can quickly skip over the multitude of lines noting that you are loading various modules. The interesting stuff is likely to be in the bottom half of the file where X is weighing its resolution options.

What exactly have you tried so far ?

It would seem to me that since its a brand new install, your X is running with vesa driver with default vsync and hsync settings for your monitor. If that's the case, you'd need to edit your /etc/X11/xorg.conf, enabling radeon driver and adjusting your hsync and vsync values to reflect your monitor capabilities.

EDIT: Didn't realize he^^ had already basically the same thing.

You probably need to find out the vertical and horizontal sync rates for your monitor, and then fill those sections in with the right numbers in the /etc/X11/xorg.conf file.

Remember to add your desired resolution in

The problem was with the horizontal and vertical sync rates, thanks for the help everybody.
