Plz help me! I have dell optiplex gx260, intel i810 video card, ubuntu lts and my screen resolution doesn't change. I'm using Xorg. I don't know what to do, I have looked for information about that problem for weeks.. But nothing helped me. My current resolution is 640x480 and thats pretty disturbing if you can imagine.. Somebody please help me!

Hi!

Try taking a look at your /etc/X11/xorg.conf. You should try by modifying that file (make backup first) and adding your desired resolution.

To echo what Mega Man X said, I think it is your xorg.conf file. I was having the same problems a while ago, but have since then figured it out. Check out post 10 of this thread to see how it worked. Hope this helps you, and make sure to tell us how it works.

I tried doing what you suggested but i can save the file and when i modified the second backup i made i cant move it to the required folder. I think it is that i dont have root access. how do i change it to mod this file???

Use sudo to execute commands as root. For example, sudo pico /etc/X11/xorg.conf will let you edit the file as root. If you want a pretty GUI, gksudo gedit /etc/X11/xorg.conf is the way to go.

I can do:
dpkg-reconfigure xserver-xorg
and change another resolution

i did as u suggested and edited the file to include my widescreen but saving the file doesnt alter the original but gave me a new one (xorg.conf.save). did i do something wrong?

edit: i got it all the way through the point where I choose what resolutions to add. im stuck as to how to enable the resolution i want.

You think I haven't try that?!! I'm not so 'newbie'.. my problem is something else..

got it to work. edited the file as directed. thanx to all who helped

I am sorry. Since you didn't mention what you have tried to do, I should have used my super powers to read your mind.

I guess if you are not newbie at Linux, you sure are very new to forums. Read this:

Also, remember to thank peoples trying to help you, either if it worked or not. We are not getting paid to answer questions here (nor you paying anything) and it is all done in our spare time. Simple words like "thanks" is the least you should do.

For now... I'm adding you to my ignore list. Since you are so pro (and I'm not), there will be no need for you to use my help.

Regards!

Is it possible to set the desktop to "1600"x"1080"? I have edited the "xorg.conf" file and restarted but it does not show up on the list. I have the hardware capability to do this.

Thank you.

Added the 1400x1050 and 1600x1280 resolutiosn in xorg.conf via dpkg-reconfigure xserver-xorg. The maximum selectable resolution in the X gui is 1280x1024. Any idea why?

Probably a sane default. In the forthcoming X.Org 7.3 they are pretending to make X dynamic so there probably won't be a need for a xorg.conf file. I guess the file will stay but for minor stuff here and there, things like resolution will be autodetected.

How do I force the Ubuntu GUI to allow 1400x1050 resolution then?

Are you using an nvidia card? They provide a really nice GUI for configuring resolutions on their latest binary driver.
