The Intel GMA500 is actually capable of hardware acceleration for HD video, but it requires some tweaking of the linux driver environment

At “Linux-Tipps“, there is a guide to enable VAAPI (Video Acceleration API) for netbooks with the Intel GMA500 graphics chipsets.

PS : If you are having problems with the display resolution resulting in your monitor/LCD not being to support and showing a blank screen, open terminal mode

Press “Ctrl-Alt-F1″ on your keyboard

Login with your username and password and Stop GDM

sudo stop gdm
or
sudo /etc/init.d/gdm stop

Copy the default-1.xml over to the Aquaria settings/preference folder as usersettings.xml [ overwriting the original]

cp ~/aquaria/default-1.xml ~/.Aquaria/preferences/usersettings.xml

Edit the xml file

nano ~/.Aquaria/preferences/usersettings.xmlusersettings.xml

Edit the video section so that full screen mode is disabled, set to 16bits mode, turn off framebuffer and turn resolution to 1024×768.

<ScreenMode resx=”1024″ resy=”768″ bits=”16″ fbuffer=”0″ full=”0″ vsync=”1″ darkfbuffer=”1″ darkbuffersize=”256″ />

Start GDM again

sudo start gdm
or
sudo /etc/init.d/gdm start

This time the game will run in windowed mode. Change the video settings within the game until it works to your desire.
Or you could also manually adjust the parameters within the ~/.Aquaria/preferences/usersettings.xml file

So what is KMS and Rootless X-Server and why the average linux user should be concerned?

KMS addresses the handling of video hardware which in turn displays the nice graphical user interface to the user. As its name suggests, means the kernel will set up the display’s resolution and depth mode (eg 800×600x32bits).
