Hi,
I own an ACER 5051AWXMi. I installed Kubuntu 7.10. I noticed that if I start my laptop with AC power X comes up with no issues.
However, if I run from battery power, as soon as boot completes and the login screen is shown the screen shows white artifacts.
Rebooting with ac power succeeds. This behavior is exhibited with the default video driver as well as the ATi driver (8.37.6).
I can confirm the same behavior on Kubuntu 7.04. I believe it has
something to do with power management. I have also noticed the following lines during boot(grabbed from dmesg):

Please advise as there seems to be no way of running the laptop on battery.
I could run PCLinuxOS(with default video driver) on battery as long as I did not run any OpenGL applications.
Upon installing ATi's driver the same behavior as in the case of Kubuntu was noticed.
This issue confines the use of my laptop to my desk. Please help.
