GMA500 (Poulsbo) gma500_gfx

@mpw You can use a similar script to reset the screen brightness on wakeup. It would look something like this:

#!/bin/bash

case "$1" in
        thaw | resume)
        echo X > /sys/class/backlight/acpi_video0/brightness
        ;;
esac

...now, to figure out the X value (unless you already know), change screen brightness with the keybard, and look at outputs of

cat /sys/class/backlight/acpi_video0/brightness

Finally, create a file named 99-brightness in /etc/pm/sleep.d/, make it executable, and you are good to go.

Well, interessting workaround, but no solution. As the brightness is just set to an average value. Thanks anyway, already better.

/edit: Is it possible to set brightness to 50% at boot, too?

[mikewhatever]

Not sure what you mean by 'avarage value'. What value did you choose, and which one do you actually want?

[mpw]

I mean, after every resume it's set to 50%, as I set it like that. Is there any option to store the brightness level before standby and set it back to this level after the wakeup?

Hello,

did anyone of you try the cedarview graphics driver? It shall have 2D acceleration, full hd video playback and poor (by default disabled) 3d acceleration. Which is much more than the gma500_gfx driver.

Looks very good, but works only with Ubuntu 12.04.1, Xorg 1.11 and Kernel 3.2. Anyway, worth a look?

Bye

For the latest work on EMGD driver please take a look at http://ubuntuforums.org/showthread.php?t=2107593 and https://github.com/EMGD-Community/in...s-linux/issues .
I provide a PPA and host all the work at GitHub. EMGD is told as being dead, but there are "just" fixes to the DRM part needed to make it work.
Finally creating good xorg.conf will make it do it smooth.
(The kernel module is currently supporting version 3.10 until 3.15 and I started on make patches for 3.16 which is release candidate)

Hi,

these are interessting news for me as I still use a Sony Laptop with that GMA500.

Do you have any plans to fix VAAPI? Because this is the thing that bothers me the most. I can't watch videos on that device, as the atom processor is too slow to play 720p and linux lacks of the driver capabilities to decode the video on the gpu.

Just mplayer would be amazing.

Hi there,

I hope it is ok to enter this thread. I started my own today (http://ubuntuforums.org/showthread.php?t=2240671&page=2), and it was suggested that I talk to you guys.

Issue:
After the installation of Ubuntu on an ASUS Eee PC, the keyboard is not working in Desktop, but working fine during the installation and in terminal mode, also the CTRL SHIFT F2 combination DID work out of desktop.
When I run Ubuntu from the USB (try ubuntu) the keyboard works fine too.

Just before the system starts I get an error message :
[13.136949] gma500 0000:00:02.0: GPU: Power management timed out.
[13.640528] gma500 0000:00:02.0: trying to get vblank count for disabled pipe
[13.642461] gma500 0000:00:02.0: trying to get vblank count for disabled pipe


This led to the assumption that the GMA500 is involved in the trouble. From the earlier posts - being very new at this - I am not sure how to proceed.

Grateful for any suggestions.

Just to say: I have subscribed to this thread in the interest of sang-gyegmx.de.

where there are solutions

there are no problems

Sorry, that I didn't take care about this thread. I just look frequently at the thread which just about the closed-source driver.

@sang-gyegmx.de : looks like gma500 (opensource driver) is still in use - make sure you've installed emgd-driver which will blacklist this driver for you.

@mpw: Take a look at the other thread. libVA is working with XBMC. Haven't built mplayer so far as I personally use XBMC often on my own. To get libVA working you'll need a downgrade to libva-1.0.16. The quickstart guide at github is just outdated.
