I have Ubuntu 11.04 (yep, I know it's old news) on my Lenovo W520. At home, I have a dock with dual monitors. I have a pretty decent setup - things work almost perfectly (hence the reason I'm reluctant to upgrade... that and I'm not 100% sold on Unity).
Anyway, the only annoyance I have is that when I'm on travel, I use the laptop screen. When I un-dock the laptop, I need to manually go into nvidia x-server settings and change the resolution from 'Auto' to 1920x1200, or it will think I have two screens, and my mouse pointer will be able to go way off the left side of the screen. This isn't a big deal, but I need to do it every time I restart the x-server (so if I reboot, or have to kill it, etc...)
What would be really nice is if there was a way for it to automatically detect whether or not there is external monitors (which it seems to do already), and switch into the mode I select, depending on which monitors are connected. Is there any way to accomplish this? I've posted my xorg.conf file for reference.
