About a week ago, I upgraded my Dell Optiplex GX520 from 10.04 Lucid Lynx to 10.10. Unfortunately, I excitedly ignored all the warnings about how it was a beta release and I'm now stuck with a big problem: the screen resolution is way too small.
Right now, when going to System->Preferences->Monitors, I see 1024x768 listed as the current display setting, with the only higher setting being 1360x768 (which is useless as it just squeezes the screen). Before the upgrade, everything looked fine- I was able to view certain websites without a horizontal scroll bar, but after the upgrade, the entire interface looks oversized and I can't seem to find a way to change it.
Is there some way I can downgrade the OS, or even my version of whatever package manages screen resolutions, so I can "reset" it to how it was working before the upgrade? Or is there any other fix that I can do?
xrandr returns the following:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.0* 800x600 60.3 56.2
640x480 59.9 59.9
This is basically what I saw in System->Preferences->Monitors... except that it looks like with a maximum of res of 4096x4096, I should be able to make it higher.
Thanks for any help in advance.
