The eeepc-laptop module does not load by default, nor will it load using modprobe eeepc-laptop using kernel 2.6.32 and 2.6.33-rc8 Reports: http://bugs.archlinux.org/task/17616 http://bbs.archlinux.org/viewtopic.php?id=87316 http://forums.eeebuntu.org/viewtopic.php?f=56&t=5138 Current fix is to add acpi_osi=Linux to boot options
this seems to be a duplicate of bug #15182, in which the ATKD device doesn't work if _OSI(Windows 2009) returns TRUE. Scott, Are you using a eeepc 1005p? If not, please attach the acpidump of your laptop.
Scott, Please try booting with acpi_osi="!Windows 2009" and verify that works the same as bootting with acpi_osi=Linux
When booting using acpi_osi="!Windows 2009" the eeepc_laptop module does not load, and modprobe fails. I am running a 1005HA-PU1X (That is commonly referred to as 1005P, correct?) My uname -a Linux scott-netbook 2.6.32 #1 SMP Thu Feb 18 14:18:07 EST 2010 i686 GNU/Linux Please tell me what information you would like, and Ill add more.

Here is the output, with both the eeepc module loaded and not: http://pastebin.com/DhLyXy8L > maybe you have loaded the asus-laptop first? > > > I am running a 1005HA-PU1X (That is commonly referred to as 1005P, > correct?) > > > I'm not sure, please attach the acpidump.

I believe that the root cause of bug #15182 could be the bug I described here, although I have not had any issues with the backlight. With the eeepc module loaded, the /sys/class/backlight/acpi_video0/actual_brightness value does change, Ill test if it does not without the module later today

Dmesg output: http://pastebin.com/YPLDnYpn And to follow up from my last response, with the module not loaded (eg, booting osi="!Windows 2009"), using the brightness up/down keys changes the /sys/class/backlight/acpi_video0/actual_brightness value by 2. I think this and bug #15182 could very well be dulpicates of each other then. Would you also like me to get some input from another user?

what distribution are you using?

When entered manually, I have the same results. I am running Debian unstable with some Eeebuntu packages. The 2.6.32 kernel had Debian patches and a video fix, I just built .33 today with the same issues. The bootloader is Grub2, Ubuntu Jaunty version 1.96.

I just tested this again using acpi_osi=""!Windows 2009"", and it works. Interestingly, according to dmesg it was booted with this command: BOOT_IMAGE=/boot/vmlinuz-2.6.33 root=UUID=049b51af-a885-4a96-a133-8b80351c15c7 ro acpi_osi= 2009 Full dmesg: http://pastebin.com/rV1WQwTp
