Today i’ve spent a couple of hours trying to fix my multi-monitor configuration on ubuntu. Note that I use a Radeon HD5830 with two monitors, and an extended desktop.
When you use the Monitors Tool, configure the monitors and then restart X, the X server seems to crash. The same happens if you use Catalyst Control Center.
My recipe to fix this behavior is the following:
- Connect both monitors
- Go to Catalyst Control Center and configure them properly (needs administrative privileges)
- Apply your settings
- Disconnect Monitor 2
- Log out and wait for login screen to appear
- Connect Monitor 2
- Voilá! You got it!
Couldn’t be easier!
