Version of Breezy tested: Colony 3 with all updates applied as of September 2 2005.
Current Issues
Hibernate will make the computer freeze after wake-up and the boot process. The desktop never appears only the boot process followed by a blank screen. The same has been tested many times with Ubuntu Hoary and worked fine.
Unplugging the AC power from the computer will make the computer freeze after about a minute. However, the opposite - going from battery to AC power - is no problem. The bug can be reproduced over and over again. Also, this is true for both Ubuntu Hoary and Breezy!
Noticeably, a test with the Linux distribution "Mandriva Limited 2005" showed that the problem does not exist in Mandriva Linux. The computer will not freeze when unplugged from AC power thereby isolating the problem to Debian/Ubuntu.

Notes
* Only by manually enabling this.
** Turns off screen and when lid is opened the "lock screen" dialogue appears. I suppose the correct behavior would be for the computer to go to sleep or hibernate when lid is closed.
