Hi Christoper,
I've tried the following options from the page you linked to:
* fglrx-installer from the repository (Login screen fine, but logging in
produces a black page with only white cursor showing)
* fglrx-installer-updates (Login screen fine, but logging in produces a black
page with only white cursor showing)
* Manually installing Catalyst 13.4 - display corrupted massively - unusable
* Manually installing Catalyst 13.4, special case for Intel/AMD hybrid
graphics - display corrupted massively - unusable
Note: None of these were usable enough to determine if display
resolution switching was happening.
** Changed in: xorg-server (Ubuntu)
Status: Incomplete => Confirmed

Title:
[Dell Vostro 3550] Display resolution keeps switching with external
monitor connected
Status in “xorg-server” package in Ubuntu:
Confirmed
Bug description:
A fresh install of Ubuntu 11.10 on a Dell Vostro 3550 with all updates (OSS
only - no proprietary drivers). When connecting the laptop to an external
monitor to extend my desktop the display settings are unstable. I choose to
enable both the laptop panel, and the external monitor setting appropriate
resolutions and apply settings. Sometimes the chosen settings do not "take". If
they do apply, and I confirm that I want to keep the settings, at random
intervals the display settings are auto-changed by the system. This may include:
- Resetting to "mirrored" displays at 1024x768
- Resetting to a single display on the laptop panel
- Resetting to a single display on the external monitor
- Some other weird combination.
E.g. When using my computer in a time range of 10 minutes i could get
through 5 different dispositions and resolutions. It could be both
display working fine, then only one but with wrong resolution, then
the two again but with mirror, then just the second, and so on.
