** Description changed: 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.
