Guide to Get the Best Performace from the GMA 500

[Mattia]

You would need to compile a custom kernel.

If you scroll up in this thread you will find more specific instructions as well as a link to a custom precise live CD I built.

thanks i like to use your livecd but is based on precise, that is in alpha.

Yes it is an alpha release.

What I have been doing is to use it on a USB with a persistent home. This allows me to save user data across re-boots and the OS has been stable. I am not as interested in updating the system while it is in alpha, but hopefully it will work in 12.04 without too much hassle.

Hello everyone.

I've got an Acer Aspire One
A0751h-52Bb with POULSBO

I'm currently on Xubuntu 11.10
Installed emgd-110 from ppa.
Resolution is OK but I still can't play videos.

I have mplayer from emgd ppa (I had to find libx264-106 somewhere else).

I use the following command :
$ mplayer -va vaapi -vo vaapi Video.avi

I have no error but black window and bad sound.

This video is fine on Windows, in same netbook, so I think Poulsbo should be able to decode it.
Any idea ? Poulsbo really sucks.

Give us output of vainfo command please.

Fedora 14 + psb = 444 frames (in 5.0 seconds) = 88 FPS
Ubuntu 10.10 + psb = 200 frames (in 5.0 seconds) = 36 FPS
Ubuntu 12 alpha + psb-gfx = 300 frames (in 5.0 seconds) = 60 FPS

I really appreciate your efforts. There is still hope.

Fedora 14 + psb = 444 frames
Ubuntu 10.10 + psb = 200 frames
Ubuntu 12 alpha + psb-gfx = 300 frames

interesting.. anyway those 300 frames with psb_gfx are (or should be if I haven't missed anything!) in
mesa software rendering (so they relies on CPU) while the other results are based on GPU opengl (as they should be).

I'm wondering if this conflicts with the resume from suspend:

$ cat /etc/acpi/powerbtn.sh 
#!/bin/sh
# /etc/acpi/powerbtn.sh
# Initiates a shutdown when the power putton has been
# pressed.

[ -r /usr/share/acpi-support/power-funcs ] && . /usr/share/acpi-support/power-funcs

# getXuser gets the X user belonging to the display in $displaynum.
# If you want the foreground X user, use getXconsole!
getXuser() {
        user=`pinky -fw | awk '{ if ($2 == ":'$displaynum'" || $(NF) == ":'$displaynum'" ) { print $1; exit; } }'`
        if [ x"$user" = x"" ]; then
                startx=`pgrep -n startx`
                if [ x"$startx" != x"" ]; then
                        user=`ps -o user --no-headers $startx`
                fi
        fi
        if [ x"$user" != x"" ]; then
                userhome=`getent passwd $user | cut -d: -f6`
                export XAUTHORITY=$userhome/.Xauthority
        else
                export XAUTHORITY=""
        fi
        export XUSER=$user
}

# Skip if we just in the middle of resuming.
test -f /var/lock/acpisleep && exit 0

# If the current X console user is running a power management daemon that
# handles suspend/resume requests, let them handle policy This is effectively
# the same as 'acpi-support's '/usr/share/acpi-support/policy-funcs' file.

[ -r /usr/share/acpi-support/power-funcs ] && getXconsole
PMS="gnome-settings-daemon kpowersave xfce4-power-manager"
PMS="$PMS guidance-power-manager.py dalston-power-applet"

if pidof x $PMS > /dev/null; then
        exit
elif test "$XUSER" != "" && pidof dcopserver > /dev/null && test -x /usr/bin/dcop && /usr/bin/dcop --user $XUSER kded kded loadedModules | grep -q klaptopdaemon; then
        exit
elif test "$XUSER" != "" && test -x /usr/bin/qdbus; then
        kded4pid=$(pgrep -n -u $XUSER kded4)
        if test "$kded4pid" != ""; then
                dbusaddr=$(su - $XUSER -c "grep -z DBUS_SESSION_BUS_ADDRESS /proc/$kded4pid/environ")
                if test "$dbusaddr" != "" && su - $XUSER -c "export $dbusaddr; qdbus org.kde.kded" | grep -q powerdevil; then
                        exit
                fi
        fi
fi

# If all else failed, just initiate a plain shutdown.
/sbin/shutdown -h now "Power button pressed"

note: i'm not able to resume from suspend pressing the power button


it is probably worth opening a new bug report for it with:
ubuntu-bug linux

these pages are useful for debug:

Hi everybody! Long time no post

I have a Viliv S7 (some random brand from Korea I believe). I was able to get EMGD working with 11.04 a while ago thanks to Tista creating me a custom emgd-config file from my xorg.0.log (thanks again tista if you see this!!). Most of the info needed was not detected by emgd config command, and the output of lshw shows "to be filled in by OEM" in all of the important places, so pretty much no documentation.

Anyways, checked back in on this thread and saw that the psb_gfx driver was coming along, so I downloaded and tried the 12.04 live cd (thanks for building that), wanted to report my results. I went as far as testing it and installing to a new partition on my netbook, so here are some tips:

On the live cd, it would boot the gui, but it was halfway off the screen. The half I could see looked great tho. If you run into this issue it is solved by going to tty (ctrl + alt + F2) and running these commands:

sudo killall lightdm

sudo dpkg-reconfigure -phigh xserver-xorg

sudo lightdm

If it does not kick you right into the gui, press ctrl + alt + F7, and you should have it working properly. EVEN MY BRIGHTNESS KEYS WORK. Incredible.

Once I installed to the SSD, I had to repeat the same steps once, blacklist the pulsobo driver, updated using apt-get, reboot and nothing. Just a black screen. So I then went to tty and on a whim tried going back to F7, and the gui had been there the whole time. Not sure why I was unable to access it, and does not select the gui by default, without going to a backend tty first, but it is apparently needed at every boot. So if you do install successfully, and end up with a black screen at boot:

"CTRL + ALT + F2", then release (does not work for me unless I completely release all of the buttons inbetween) then "CTRL + ALT + F7"

So with a few obnoxious quirks I have a completely working 12.04 install with psb_gfx. If anyone needs any config files or logs from an actual install let me know, I would happy to post.

Thanks again for all your great work guys!

Glad you got it working. I posted some additional information

http://blog.bodhizazen.net/linux/ubuntu-gma500-live-cd/

There is some information about persistence as well as settings to use with grub, in particular ...

edit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="poulsbo.blacklist=yes console=tty1"

Alternately, install this kernel (it works out of the box)
