Title:
Toshiba R835-P56X - screen brightness control does not work after
suspend/resume
Status in “linux” package in Ubuntu:
Expired
Bug description:
Toshiba R835-P56X - screen brightness control does not work after
suspend/resume. It works just fine before suspend/resume. After
suspend/resume, the dbus (or whatever) indicator shows the brightness
slider-bar changing, but the screen brightness doesn't actually
change.
Restarting acpid or acpi-support doesn't make any difference. Only
workaround that I've found so far is to reboot the machine.
I'll be happy to perform any tests that you all can suggest, as well
as provide more/deeper debugging information. I've been a Linux
user/sysadmin since 1998, and I'm proficient in
programming/development -- but I'm mostly unfamiliar with the acpi and
Linux's implementation of it.
