I'm using Karmic, non net-book remix. I've looked around google for the past few hours and found nothing, sorry if I missed a fix. When changing the brightness via Fn+f5/f6 the brightness changes randomly. It does the same when moving the slider in gnome power manager. Is there a fix for this somewhere? It makes the dim when idle feature completely useless, since the screen gets brighter. Thanks in advance, Jason

First as last bump. If anyone has any ideas, let me know.
Have you tried this: http://ubuntuforums.org/showthread.php?t=881241
_______________ - anaconda
this will make the brightness keys work: sudo gedit /etc/default/grub Find the line GRUB_CMDLINE_LINUX_DEFAULT and add "acpi_osi=Linux" so it looks like this GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux". Save the file. Now run update-grub2. sudo update-grub2 But gnome power manager still randomly changes the backlight. I disabled it from startup, and start it from the command line when i want to suspend on closing the lid.
Thanks finnk! That works in my asus eee 1005P too.. How did you figure that out? I googled for hours without finding a solution. And I was researching a completely different approach, with using xbacklight and xgamma, which both work too..
Good stuff Finnk. Gnome power manager is still sorta screwy, cycles through the brightness levels 3 times, but at least there some order to it. Thanks a lot! FN keys work perfectly though. Other than having to manually make a fancontrol file and a network issue leaving standby, ubuntu has been nearly flawless on the EEEPC for me. Great job all the devs out there.

@anaconda I got it from this debian wiki: http://wiki.debian.org/DebianEeePC/Model/1005pe @MilitantPotato I haven't thought about the fan control, does it by default run at constant speed? How does your fan control file look like, and where do you put it?
My fan ran at ~3950 rpm constantly, hovering around 54C. here's my /etc/fancontrol /etc/fancontrol: INTERVAL=2 FCTEMPS=hwmon1/pwm1=hwmon0/temp1_input FCFANS=hwmon1/pwm1=hwmon1/fan1_input MINTEMP=hwmon1/pwm1=64 MAXTEMP=hwmon1/pwm1=80 MINSTART=hwmon1/pwm1=10 MINSTOP=hwmon1/pwm1=0 It's not perfect, but it idles with the fan off and saves a noticeable amount of battery. Kicks up to full speed around 67C. I had to make the settings myself since pwmconfig didn't detect any fans. /etc/init.d/fancontrol setup: http://pastebin.com/CRTBwbfe 'sudo ln -s /etc/init.d/fancontrol /etc/rc3.d/S99fancontrol' for it to start at boot 'sudo chmod 0755 /etc/init.d/fancontrol' so it executes. I'm not sure where I got all the scripting for that, found it on google after a few hours of searching.

Excellent ! It solved my 1005PE backlight issue as well
@MilitantPotato You mentioned a network issue leaving standby. I probably have the same problem, but I couldn't find any info to solve it, nor anyone reporting the same issue (so far). In my case, ethernet does not resume correctly. After suspend, the wired network does not work, nor it does the wireless, if I try to turn it on. The ethernet hardware is not recognized any more and it does not show up on a "lshw -C network" command. On the contrary, if I turn the wireless on before suspend, then it is resumed correctly. Did you find any fix to this? Thanks!
