Black screen after changing resolution to 1600x1200


After I change my screen resolutions to 1600x1200, X boots into a black screen.
I have a Dell Latitude C840. I remember setting the HorizSync to 59-85 and VertRefresh 40-90 by google (I couldn't find the information anywhere on my manuals).

Anyway, I can ctr+alt+f1 to console but got no idea what to do next. any help will be greatly appreciated!

Well maybe it's not in your $PATH. Try entering the full path with the command
/usr/X11R6/bin/xf86config

1600x1200 on a laptop? Are you certain it's capable of displaying that resolution? Can you do it in windows?

Try this to get you to a starting point at the cml

XFree86 -configure
XFree86 -xf86Config /root/XF86Config.new
cp XF86Config.new /etc/X11/XF86Config

If you see a blank sceen with an X cursor, type ctrl-alt-backspace to get back to the terminal

or before you do the above, go to /etc/X11/
and see if you have an XFree86Config.* and just copy that file to XFree86Config.
Basically everytime you make an adjustment, the old XFree86Config file is save as XFree86Config.*

Hope this helps

At command line, find and cd to #etc/X11
edit XF86config using vi. (find instructions on using vi) it is very simple, there are four commands you need to know.
to open the file, vi /etc/X11/XF86config

[ i ] inserts text
[ esc ] exits insert mode
[ :q! ] abandons all edits and exits to command line
[ ZZ ] saves all edits and exits to command line
always remember to [ esc ] , and all commands are case sensitive.

change horiz to 49-70
change vert to 49-70
Change size to 1024*768

startx, then if it fails
keep changing these settings until it works.
