ASUS O!Play HD2 playlist handling

So I own an ASUS O!Play HD2 and apart of many small problems, I had a huge one: I couldn't make it to load playlists. I've quite large music collection (20,000+ mp3 files), and listening to full folders at a time is just not what I've bought a media center for.

Matrox G550 problem with xinerama xf86-video-mga-1.5.0

Previously I have had problem with mga driver 1.4.11 and xinerama extension on Arch linux, that I've resolved by manually patching the driver, using Ubuntu folks patch. (if you need xserver-xorg-video-mga-1.4.11, check out my previous post)

After an upgrade to kernel 3.3 the driver stopped working, as new version 1.5.0 has come out, obviously without the patch. It took some time, but finally I've got it working.

You can find the patched driver here.

Matrox G550 xinerama problem on Arch Linux v1.4.11

As I've spent a good few hours researching solution for the problem, I just share the solution as it seems to be rather unobvious:

The Xinerama support for the stock driver is not working, when starting X it comes up with the error

>MGA(0): Unable to map BAR 0. Invalid argument (22)

Some great folks have solved the problem for Ubuntu here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-mga/+bug/292214

Though the patch found there for some slight differences in the structure of the mga driver source from arch and from ubuntu won't work.

I've manully patched the driver (version 1.4.11), and it does work now.

You can download the patched source of 1.4.11 from here.

Also a working xorg.conf is found on the page.

Good luck!
