perfect!! Thank you soooo much!
perfect!! Thank you soooo much!
after step 5, the message:
appears.Code:xrandr: screen cannot be larger than 800x600 (desired size 1024x768)
I know that this is not the case as this computer has always used 1024x768 before now, it has just started having these problems in 10.04. my monitor is an old CRT type, so it should support all screen resolutions anyway. sometimes my computer starts up as it should with the 1024x768 option, while sometimes it does not.
any help would be much appreciated as most web pages do not display correctly in 800x600 mode.

After closing some game my display resolution turned into 640x480 so I tried to modify xorg.conf to the following but I noticed that there are disappeared sides (at right & left) in my monitor and fonts appear small and ugly!!!
How can I fix this issue?
----xorg.conf-----

PS
I tried to change display resolution from display settings before modifying xorg.conf but I couldn't find any resolution bigger than 640x480 so I forced to change the resolution manually
Another thing, I tried the tip mentioned above but it didn't work because I got the following error message:

I installed Ubuntu 10.10 Meerkat. Then my screen resolution was 1024x768(19" screen)
It was acceptable.
Now, I updated my system using Update manager and after restarting and now it is 800x600.
I read all the posts in this thread and tried them
saimanoj@saimanoj-desktop:~$ xrandr
xrandr: Failed to get size of gamma for output default

Thanks for the post. I can finally run higher than 1024x768 on a 19" monitor. I have a question that arose when messing with the /etc/gdm/Init file that is a little off topic, maybe someone could help point me towards the answer. It looks like some settings for the initial login (gdm?) are here. Is that correct? If so can they be changed to make the login box look different? I have found ways to change the colors and picture, but I would like to make the box either transparent or just the input box displayed without the rest of the stuff. Thanks again.

I'm using ubuntu 10.10
Today I woke up and turned on my ubuntu desktop to find that my large screen resolution was no longer available.
I've tried the various solutions in this thread but they did not help.
- xrandr says today that the maximum resolution is 1024x768 (yesterday I had a much higher resolution, probably 1920x1200).
- reinstalling gnome.session made no difference
- attempting to install envyng-core using Synaptic Package Manager only leads me to believe that envyng-core does not exist (not found)
- running dpkg-reconfigure xserver-xorg (with gdm stopped) did not help
Yes, it's NVidia. Everything worked fine yesterday, I did not install or alter anything, and today the machine is different.

This is NOT SOLVED for most people here!!!!
Ubuntu and Diabol/Canon- ical are as ***t as ever at dealing with unrecognised monitors. FFS solve this problem properly!
After inserting:
on step 3 I get the following output:Code:xrandr --newmode "1280x800_60.00" 83.50 1280 1352 1480 1680 800 803 809 831 -hsync +vsync
Is there any way to fix this ?Code:xrandr: Failed to get size of gamma for output default
