screen resolution

In fiesty it is located in the universe repository.

In gutsy or hardy it is located in the standard repository and can be installed from the terminal

sudo apt-get update
sudo apt-get install displayconfig-gtk

If you are using intrepid this package is not supported. Then to get better help please provide the output of this command from the terminal

lspci | grep -i vga

Hope this helps

i'm using intrepid:

00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03)
02:0b.0 VGA compatible controller: ATI Technologies Inc Rage 128 PP/PRO TMDS [Xpert 128]

now what...

AFAIK displayconfig-gtk is removed from intrepid.

run

applications -> other -> Screens and graphics

or look under

System > Preferences > Screen Resolution

and manually select the resolution

no where can i chose my graphics card or screen model, i know i did it in hardy, but don't know how to do it in intrepid.

Quite. displayconfig-gtk is gone and applications->other->Screens and graphics merely points at that. Has this function been replaced in Intrepid, or do we have to go back to hacking the conf file?

i don't know enough to hack, if you know what to do i'd love to find out.

Maybe I can help, but I don't know what the original problem is! Please explain what you are trying to do.

i recently had to reinstall, and when i reinstalled my monitor was not detected. so it is stuck in lo graphics. that is my problem.

Have you tried to enable the drivers for your graphics card. Please check in System-> Administration-> Hardware Drivers.

Hopefully, there will be a driver listed there that you can enable. The xorg.conf files has largely been deprecated in intrepid so xorg.conf hacks may not be able to solve this problem.

Also it appears you have two graphics cards an integrated Intel and an ATI card. I assume you are using the ATI card.

If it helps, I had a similar problem in Hardy: the monitor wasn't detected because it wasn't there - I was using VNC. Using displayconfig-gtk I ended up with the xorg.conf file which follows. This one has since been modified by the upgrade to 8.10, but it still works for me on a pretty ordinary CRT display. I've commented out the reference to my video card, and you may need the Driver "vesa" line if your video card is not properly detected. If you have a LCD, some of the timings may not work, or may even be dangerous! I read that someone else has re-installed Hardy, generated this sort of xorg.conf file for his monitor/video and then copied it back into Intrepid.

Back up /etc/X11/xorg.conf and copy the following in there as a new xorg.conf and re-boot. Good luck.
