Screen Resolution Problem In Ubuntu

xLunatiK · 09-10-2005, 04:08 PM

I'm stuck in something like 800x600 and in the Resolution changer it's the only choice that I'm given. I've found things on the internet telling me to do something with xorg.config but they confuse me.

Any help is appreciated.

i'm a big newbie too, and i just got this fixed for me. I have debian sarge, but apparently ubuntu is based off of it.

anyway, go into the filemanager and get to root.

go in etc, this is where configuration stuff is.

I have a folder called "X11", i don't know what you have, but maybe it'll be "xorg" for you. x.org and x86 are the desktop environments, and since you're trying to configure them, that is the place to look

find a file like xorg.config or something. for me it's "XF86Config-4"

now that you know where it is, it's time to edit it.

unfortunatly you can't edit it as a regular user, so you are going to have to change it as root

open the shell and type 'su' this will change you to root

cd is change directory, so type "cd /etc/X11" or whatever the folder was for you

try kedit XF86Config-4
or whatever the config file you found you wanted

scroll around untill you see some lists of screen resolutions

you might see something like:

Code:

	SubSection "Display"
		Depth		24
		Modes		"800x600" "640x480"
	EndSubSection

just change it to be whatever like this:

Code:

	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" "800x600" "640x480"
	EndSubSection

save it and exit
go to the shell and type exit. this will log you out of the root user, so type exit again.

now, i think i had to restart to get it to work, so try that.

anyway, i don't know if this will work for you seeing as how we have different distros but maybe they're close enough to the same thing.

yes ubuntu is based on debian. i tried debian once i burned the mini and when it booted all i got was command pronpt. i havent tried it since i might go for the full cd downloads and try it that way. i hated ubuntu at first also but out of the 3 distros im running i use ubuntu most ,. i learned to love it i think

The command kedit doesn't work even if I sudo first. How do I edit the xorg.config file?

If you're using Kubuntu, use this command:

Code:

sudo kwrite /etc/X11/xorg.conf

If you're using Ubuntu, use this command:

Code:

sudo gedit /etc/X11/xorg.conf

I'm having a very similar issue -- I have just installed Ubuntu 5.04, and am unable to switch out of 640X480 (60Hz). The xorg.conf file shows a range of possible values (1024X768, 800X600, etc.), and properly indicates my monitor (NEC 1860NX). I've looked at the log file for xorg, and don't see anything that would indicate a problem (though I'm a newbie at all of this -- it's quite likely that I'm missing something). Any guidance you can offer would be most welcome. Thanks!

I have similar problem. My widescreen moniter (1200x800 native) is stuck at 1024x768 and Ubuntu 6.06 LTS doesnt offer me any other options I have tried messing with xorg.conf and to no success. that entire code follows. Sorry about the length of this post.

I was stuck in 640x480, very hard on the eyes.

The thread above contains the post that helped me solve the prob. Also, I've always only been able to run 1024x768 under Ubuntu, and just figured I'd have to deal with it. However when I followed the instructions above, I was able to change my screen resolution to 1280x960, which I prefer over the former...

I just installed Ubunto 8.04.1 Hardy Harron. My screen resolution is at 800x600, i need it to be at 1024x800. I don't have the option of changing it under preferences because 800x600 is as high as it will go. Could someone explain this in VERY VERY VERY simple steps. Thank you in advance.
