I just got finished installing Fedora 9 on my PC and I was having trouble with the screen resolution. I have a 17" Envision EN-775e monitor and my system has a VIA/S3G UniChrome Pro IGP 64MB onboard video chip. The problem was that the highest resolution I could choose was only 800x600. I detemined that the video card driver was in fact correct (Fedora automatically loaded the openchrome driver) so the problem must be with the monitor. So to configure the monitor I went to System->Administration->Display clicked on the Hardware tab and then clicked on Configure (to the right of Monitor Type). Then I clicked on Generic CRT Display and put a check in the box beside Show all available monitors. After discovering that there are no choices for Envision I clicked on the drop-down arrow next to Generic CRT Display and chose Monitor 1280x1024 because 1280x1024 is the resolution that I was using for Windows on this machine. I then clicked on Ok and then Ok again, logged off and then I got the following message on my monitor: Attention Out of Range
H:74.8KHz V:59.Hz So, I did a little research on another machine and determined that I would have to manually edit the xorg.conf file (/etc/X11/xorg.conf). To do this I first had to get to the command prompt so the pressed Ctrl+Alt+F1 on the keyboard to drop out of graphical mode. Then I logged in as root and edited the xorg.conf file with nano. To do this you would type the following: nano /etc/X11/xorg.conf
I changed the "Monitor" and "Screen" sections to the following, saved and exited the xorg.conf file, rebooted, and Eureka! - I was able to login to the graphical environment again! Section "Monitor"
Identifier "Monitor0"
ModelName "Envision EN-775e"
HorizSync 30.0 - 72.0
VertRefresh 60.0 - 85.0
