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! -complete noob |
At the command prompt try xf86config
|
I got command not found :(
|
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?
|
Yep, that's my LCD's natural resolution. RH9 refuses to work in 1600x1200. Aggghhhh
|
What chipset does your video use??? Is it the Radeon 7500 series like in the C640???
|
I have the geforce 4 440 go

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. |
