LCD Brightness resets to lowest on bootup with laptop ubuntu amd64

[Johnny Jelinek IV]

Install Ubuntu Breezy or Dapper AMD64; brightness resets right before hitting Ubuntu boot screen, but after grub.

My laptop is an eMachines M6805 (no longer in production).

See the LaptopTestingTeam page for more details:

Clarification: Brightness resets on EVERY boot of Ubuntu amd64, not just for install.

I have the same issue with my M6805 laptop. Both of those distros do the same thing for me. I have tried different distros also. Mandrake and gentoo both have this issue. It maybe a kernel configuration thing.

it doesn't do it on x86 version, just amd64 :/ dunno why.

It does do it on x86 here ... with Hardy RC.
