I have a Lenovo Z570 dual booting Windows 7 and Ubuntu 12.10 very happily. I love it, and I'm fairly sure I want to switch permenantly. The laptop has a 1366x768px built in screen, and is connected to a second monitor, resolution 1680x1050px.
At login, both screens are mirrored, and both screens are set to 1024x768px. On logging in, I can set the laptop screen to the correct resolution, but I had to use xrandr in command line to add the correct resolution for the second monitor. I also set a nice desktop background.
On restarting, I get a window saying "Could not apply stored configuration for monitors". It's back to mirroring at 1024x768, and my desktop background is gone.
How can I get the correct resolution at login, keep my desktop background, and not have to mess around in a terminal window every time I reboot?
Any help greatly appreciated!
