Only 640x480 resolution found after update

[Andres Mejia]

With Kubuntu feisty installed, after updating today, 04/14/2007, the only resolution available for my hardware is 640x480. It use to be at 1024x768. I'm using the i810 driver.

Attach here your /etc/X11/xorg.conf

You can also try.. sudo dpkg-reconfigure xserver-xorg

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add your '/etc/X11/xorg.conf' file and your '/var/log/Xorg.0.log' file as attachments to your bug report? Thanks in advance.

that config cannot be from ubuntu.. Please run 'sudo dpkg-reconfigure -phigh xserver-xorg' to see what the xorg.conf looks after that.

I no longer have access to the computer that was having this issue so I'm going to abandon it. I'm posting what computer this affected in the bug description for future reference.

[Andres Mejia (amejia1)]

Nevermind, found another computer this affected. The previous computer was a Gateway GT5404 desktop through its integrated graphics card. It's also affecting a Gateway GM5416E desktop. Going to post xorg.conf and Xorg.0.log.

This much sounds like a dupe of 3731. Ubuntu doesn't recognize your monitor and is picking generic values that don't match your monitor, and the only resolution it can be sure to work is 640x480.

A workaround is to look in your monitor's documentation and lookup the horizsync and vertrefresh rates, and then edit your /etc/X11/xorg.conf file and change those values to the correct ones for your monitor. Presently, the xorg.conf files you attached just show this generic monitor setting.

Hopefully for Gutsy we'll both get the automatic detection working right, and include a gui tool of some sort so folks don't need to hand edit the xorg.conf, but for now the workaround is the best option.

If you have any further trouble, please join the discussion on 3731; I'll mark this one as a dupe.
