how to set monitor resolution

[linuxconfuser]

Hi,

My monitor is dell e248wfp (with 1920*1200 resolution), however i couldn't find it in Suse 10.3. So how should I set the resolution to correct one (1920*1200)?

You can just manually edit your /etc/X11/xorg.conf
see for the 'Modes' section and edit it.

if it doesnt work, boot to terminal and edit it back to the previous.

if you use gtf in a terminal window it will give you the Modeline for your xorg.conf file

gtf 1920 1200 75

You may have to play around with the 75 to get it right. If that's ok for your monitor you should be able to make the new modeline the first choice.
It's fairly easy to follow once you open xorg.conf (as root).

Which Graphics Card do you have?
Execute this

su -
/sbin/lspci | grep -i vga
grep -i driver /etc/X11/xorg.conf

Post output here.

the graphic card is Nvidia 8300GS.

I have used "sax2" and try to set the resolution. I tried twice, both failed, and the WORST of all, the system won't boot (each time after I change the resolution, it ask me to re-boot, and when I try to re-boot, the whole system crashed)

So I have to re-install suse twice.

Now the problem is: if i set the resolution wrong, how can i set it back to the previous one? how can i know i set the resolution right WITHOUT reboot?

All xwindows IO is basically controlled from one file.

/etc/X11/xorg.conf

if you save a backup (actually there normally is one) of this file in a working configuration you can from a terminal copy the backup back to the original name and restart xwindows to get back to a working GUI

some hints

You must be root to edit or change this file

in a terminal here are some useful commands

init 3 will stop the GUI
init 5 will restart the GUI (also startx)

pressing ctrl-alt-FX key where X is 1-7 will take you to terminal X
note 7 is the GUI 'terminal'

pressing ctrl-alt-backspace when in th GUI will stop the GUI

cd /somedir changes directories

cp file1 file2 copies files from one name to another

ls or dir lists the files in a directory.

If you are not comfortable with vi (text editor) try joe

thank you all. But I am very new to linux, and I am not very familiar with editing these files.

can anyone suggest how to use "sax2" or other graphic tools to set resolution? and, how can i know i set the resolution right WITHOUT reboot?

[gogalthorp]

The only way to restore things is what I outlined above. ie copying the xorg.conf file to restore it's previous state. But if the GUI is messed up you must do it from a command line ie a terminal and you must be logged in as root.

You could try selecting a monitor with close specs in Sax2

[linuxconfuser]

i read some other articles, and i think it is probably the driver is not right. The graphic card is Nvidia8300, however, what Sax2 is using right now is "vesa 1280*1024".

How do i know what driver is currently in use? And where to find the right driver for Nvidia8300?

If your seeing versa then your not running the correct driver.
