I installed some new packages on ubuntu and it killed my resolution. My screen is wxga, and thats how it was configured, but then when the new files installed and X was rebooted, the resolution changed to 1024x768 wtf? needless to say everything looks bad. i checked xorg.conf and everything is configured correctly there.

i noticed there is a program if you go System>Prefererances>Screen Resolution lets you change resolutions, and its giving me 1024x768 and 800x600 as options...nothing widescreen?

whats going on? anyone wanna gemme a hand?

ummm maybe if you look in your . files for something that has the same name as your screen resolution app???? IDK that's freaky though. Have you tried uninstalling those apps to see if it comes back to normal?

i think that little resolution changing app is part of the ubuntu package for gnome 2.12 (maybe even part of gnome?) What freaks me out the most is that the xorg.conf is right, yet gnome doesn't want to listen to it for some reason.

Ok I did some experimentation. Is there an entry in your xorg.conf in the mode lines section that actualy says it's for the corresponding refresh rate. Evidently it will scan the mode lines sections for any that match both the refresh rate in the monitor section and the resolution options set in the Screens and display subsection specifically. I quickly looked and found anthother 60Hz refresh rate resolution and added it to my DIsplay subsection and it showed up in the resolution prefs applet. Having just resolution in the display subsection wouldn't work. it had to mach the refresh as well. Good luck.

hm.

I've just have a resolution problem and solved it. It's seems like ubuntu is quite stupid on screen resolution.

First I booted to single user mode by a grub option,
Then I run Xorgconfig or something like that which gives me a text screen wizard inorder to set screen resolution manually. (try to look in /usr/bin/X11/Xorg* xorg x... whatever)

The text wizard gives me an appropriate xorg.conf.

i first edited xorg.conf manually. then i decided what the hell and ran the wizard. the command for that is "sudo upgrade-reconfig xorg-base" i believe . anyway....the wizard ran and configured everything correctly. i rebooted x alt+ctrl+backspc and it is still gay. I figured maybe it was a gnome problem, but no because the login screen is also in the wrong resolution. At any rate i went ahead and installed fluxbox. and what do you know, fluxbox is also a bit fuzzy so its deffinatly not a gnome problem.

I don't know what else to try. Can you post up your xorg.conf, maybe a fresh pair of eyes looking at it could spot something. Is there any thing in the log file about a bad resolution?

This is what I did to get my display looking perfect and to display fonts perfectly: (I had to do the calculations to get my resolution settings)
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

Step 1. Configure X and Gnome to 96 dpi
Code:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
sudo gedit /etc/X11/xorg.conf


Locate Section "Monitor" and add the following lines before EndSection:
Code:

# DisplaySize 270 203 # 1024x768 96dpi
# DisplaySize 338 254 # 1280x960 96dpi
# DisplaySize 338 270 # 1280x1024 96dpi
# DisplaySize 370 277 # 1400x1050 96dpi
# DisplaySize 423 370 # 1600x1400 96dpi
# DisplaySize 444 277 # 1680x1050 96dpi

Uncomment the line corresponding to your current resolution.

To get other values, use the following formula:
displaysize = <pixelsize>/96*25.4

Either restart X or reboot, after which verify the dpi setting is correct:
Code:

xdpyinfo | grep dimensions xdpyinfo | grep resolution

If the resolution is not 96x96 dots per inch slightly adjust the DisplaySize values until correct.

Configure Gnome to run at 96 dpi in System > Preferences > Font > Details
