Bug Description

Computer: Acer Aspire 5610Z laptop
OS: Ubuntu 7.10 with all updates
Graphics: Intel, with a widescreen LCD (it is a laptop)

People on pictures and movies were unnaturally fat and short.
I downloaded a package from APT, called 915resolution, to give me the correct resolution: 1280x800.
This worked fine.
If I press Ctrl Alt F1 to go to terminal (works fine), and then go back to Gnome using Ctrl Alt F7, a problem occurs.
It now uses this resolution: 1400x1050.
I can not turn it back to 1280x800 using the "Screen and Graphics" utilities.
The resolution I want is in the list, but pressing OK doesn't change anything.
Has this got anything to do with the 915resolution package?

Control-alt-backspace restarts X, and it works like it should again. So it's not critical, only ANNOYING. I'm sure the fix is simple, but I am such a n00b.

When the computer uses 1400x1050, the desktop works like an old Amiga side scrolling game.
The entire desktop follows the mouse smoothly. If I move the mouse to one corner, the desktop will move so this corner shows up on the screen. The oposite end of the wallpaper is beyond the limits of the LCD panel.

Please attach your file /etc/X11/xorg.conf. I guess you are still using the i810 driver instead of the new Intel driver.
Btw. please attach file '/var/log/Xorg.0.log' and the output of "lspci -vvnn", "sudo ddcprobe" and "xrandr " too.

I am at work now, and the laptop is at home.
I can give you that information in roughly 8 hours from now.

You may be right about the i810 driver, but I am not sure.
I can confirm this in 8 hours from now, when I am back from work.

I thought that Ubuntu kept itself up-to-date.
Where do I find a newer driver than the one I use now?

I am closing this bug report because you are still using the deprecated i810 driver.
Please change the line
Driver "i810"
to
Driver "intel"
in your xorg.conf with the command "gksu gedit /etc/X11/xorg.conf" and save it afterwards. After an X restart you should be able to select the correct resolution with Screen Resolution.

Thanks man, that did solve the problem. And everything works like it should (tuxracer.)

But in Xorg.conf, there were two places where Driver "i810" was mentioned. I changed both into Driver "intel".
Why two?

I don't know where you got the xorg.conf, but it does not look like the one that the configuration scripts generate.
