Switch from 17" monitor to 15" monitor. Need to know how to change settings.
My 17 inch monitor took a dump last night, so I replaced it with a 15" monitor that I had laying around. Now whenever I boot up into linux (Red Hat 9) from the bootloader, My screen is scrambled. The boot loader comes up correctly and then all the text that normally comes before you login to the machine is fine. It scrambles when I get to the login screen. I beleive the problem is because the settings on the machine are still set for 1024 X 768. I beleive that the 15 inch replacement is not capable of handling such a high resolution. How can I change this setting before my computer boots into the login screen?
