This is a bit of a beginner problem I've run into that I'm determined to fix somehow, on Acer Aspire 5732Z with Intel GMA 4500M.
General system info:
[enoch@arch-ACER ~]$ uname -impr
2.6.38-ARCH i686 Pentium(R) Dual-Core CPU T4400 @ 2.20GHz GenuineIntel
[enoch@arch-ACER ~]$ lspci -v | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
When booting without KMS enabled, the backlight brightness works perfectly fine, however this is not how I want to use my laptop.
[root@arch-ACER backlight]# ls
acpi_video0
[root@arch-ACER backlight]# cd acpi_video0
[root@arch-ACER acpi_video0]# ls
actual_brightness brightness max_brightness subsystem
bl_power device power uevent
[root@arch-ACER acpi_video0]# nano actual_brightness
[root@arch-ACER acpi_video0]# nano brightness
[root@arch-ACER acpi_video0]#
However, when booting with KMS enabled, the actual_brightness is 0 (no brightness), and working without light is not a very usable environment.
