WideScreen Resolution HowTo

Most of this information has been obtained by searching on net. However, the information
has to be hunted. This is for using 1366x768 (wide screen) resolution on Fedora 5.

After startx, a file /var/log/Xorg.0.log is created. Use your favourite editor (say vim)
to search for "Supported" (part of file is as follows)

(II) I810(0): Supported VESA Video Modes:

Edit /etc/X11/xorg.conf (after saving previous version) to add following line (in red):

Section "Monitor"

### Comment all HorizSync and VertSync values to use DDC:
### Comment all HorizSync and VertSync values to use DDC:
     Identifier   "Monitor0"
     VendorName   "Monitor Vendor"
     ModelName    "WideScreen"
     DisplaySize 410    230
### Comment all HorizSync and VertSync values to use DDC:
     HorizSync    30.0 - 83.0
     VertRefresh 56.0 - 76.0
     ModeLine     "1366x768" 85.5 1366 1436 1579 1792 768 771 774 798
     Option        "dpms"
EndSection

And also add "1366x768" (in blue):

Section "Screen"
     Identifier "Screen0"
     Device     "Videocard0"
     Monitor    "Monitor0"
     DefaultDepth     24
     SubSection "Display"
         Viewport   0 0
         Depth     16
         Modes    "800x600" "640x480"
     EndSubSection
     SubSection "Display"
         Viewport   0 0
         Depth     24
         Modes    "1366x768" "1024x768" "800x600" "640x480"
     EndSubSection
EndSection

Start X one again. If you do not get desired display, then look in /var/log/Xorg.0.log
and search for 1366x768. You may find a line like:

(II) I810(0): Not using mode "1366x768" (no mode of this name)

Search rpm repositories for "915resolution" (maybe old versions are here.)
Install RPM as usual--- using "rpm -i 915resolution*.rpm" (as root) and follow the directions of README there
(As root display the available resolutions :
        # 915resolution -l
Overwrite mode (say 38) as
        #915resolution 38 1366 768 24)

Starting X once again should give the desired resolution. If yes, append (add) the line:
     915resolution 38 1366 768 24
at the end of file "/etc/rc.local"
