Bug Description
Setup is Lenovo T400 in a docking station with two Samsung SyncMaster 2243BWX monitors.
- ATI video card, with open source drivers only (I did not install the proprietary fglrx drivers)
Steps to reproduce:
- Connect both monitors to docking station
- Power up the laptop
- Login screen appears, I log in normally
- Desktop appears but with no panel and no unity launcher
- Although mouse moves, it is unresponsive to clicks and the keyboard does not respond either - only option is a hard reboot.
Workaround:
- Unplug one of the two Samsung monitors
- Reboot
- Log in normally, unity desktop, panels and launcher appear normally
- Plug in the second Samsung monitor, it connects normally and the system is fine
Regression
- This bug appeared after I installed Natty beta 2
- As of yesterday, using the daily build of Apr 13th, I was using the two monitors just fine
