Bug Description
Lcd panel brightness adjustment doesn't exist on gnome power manager. I also couldn't find laptop panel from Hardware information. Function keys to adjust screen brightness do work. This applies to Ubuntu 7.10 x86.
On 7.04 the lcd panel is recognized and brightness adjustment does exit in power manager. I checked out this running livecd. I found modules ibm-acpi and backlight loaded (+many others), when on 7.10 only thinkpad-acpi is loaded. Module backlight doesn't seem to exist on 7.10. So this could possibly be a kernel issue.
