Glad you found and liked the script =)

I have the solution (although I think you have also stumbled across it yourself). I have acer_wmi blacklisted. I ran a quick test and with this module loaded the backlight keys will not work without a workaround such as bodhi has suggested. If you blacklist it then the backlight keys should work fine.
Hope this helps!
Edit: this link explains what acer_wmi does...

Yes, it helps a lot. Just by removing the module with rmmod it started working
Thank you very much!
PS: It's nice to read in your link that it's blacklisted in Aspire One series
NOTE: The Acer Aspire One is not supported hardware. It cannot work with acer-wmi until Acer fix their ACPI-WMI implementation on them, so has been blacklisted until that happens.
Hi,
I have installed 12.04 from
http://blog.bodhizazen.net/linux/ubuntu-gma500-live-cd/
on my Vaio X11. And it works, except for the fact that gray-tones flicker a bit. (It seems that the Vaio P's has a similar issue, see comments in http://blog.bodhizazen.net/linux/ubuntu-gma500-live-cd/)
I tried to resolve the problem using the following customized xorg.conf:
which is an adapted version of the xorg.conf posted by tista once for EMGD.Code:Section "Device" Identifier "Device0" Driver "fbdev" EndsectionSection "Device" Section "Screen" Identifier "Screen0" Device "Device0" Monitor "VAIO-LVDS" SubSection "Display" Depth 24 Modes "1366x768" EndSubSection EndSection Section "Monitor" Identifier "VAIO-LVDS" ModelName "SNY" Modeline "1366x768" 74.06 1366 1429 1557 1663 768 768 769 775 -HSync +VSync EndSection Section "DRI" Mode 0666 EndSection Section "Extensions" Option "composite" "enable" EndSection
It doesn't help, because the modeline is rejected, because it fails some kind of test. Here is part of the /var/log/Xorg.0.log:
I also tried other modelines, generated with the gtf command. I always get the same result.Code:...

What else can I try?

Well, I've tried http://blog.bodhizazen.net/linux/ubuntu-gma500-live-cd/ on my 1101HA, and the result is still the same. Ever since the psb_gfx module started being added to the kernel (on 11.10) I get kernel panics. Sometimes X starts and works for a minute or two, with a huge screen "wavery effect", equal to what I got with the EMGD drivers and the powersave (underclock) profile. But after that minute or two everything hangs and I end by having to turn the netbook off using the power button, as even the sysreq key isn't recognized.
Hi Juerg..
Yeah I could confirm that today psb_gfx might ignore any special xorg.confs.... My P seems the same.
But one thing.
I didn't experience such "gray-flicker" on any desktop sessions, so let me know that details.. I only have an ugly glitch of "missing mouse pointer" now. IMHO, this would cause GEM "fixed memory object" which must be kept anytime via kzalloc or so, but today this didn't work properly. Then cursor object would be wiped out from gem memory map tackled by any other memory object something like "overlay" object on compositor. So especially on time when "heavy load" comes out, the mouse pointer might be vanished..
Finally, kernel 3.4 would bring the whole new psb_gfx to us.
Cheers,
Tista

Hi,
are there any patches available yet for compiling emgd-dkms 1.8 or 1.10 on Kernel 3.3?
