Hi,
Thanks Doozer and ves for your support.
So, things are not going smoothly:
1. Update to 0.171. I did the update using the
gasetup function. There was no error during the update process. But when I try to start groovymame, here is the output:
groovymame: error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory
I tried to install
qt5-base using pacman, but I get dependencies conflict.
2. The update of the distribution using
pacman -Syyu, the download goes well, but at the end I get this error:
(405/405) checking package integrity [######################] 100%
error: package-query: missing required signature
error: yaourt: missing required signature
error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.
And it stops there.
3. I doubled the RAM, now there 1 GB. I thought 512 MB was necessary, my bad.

4. The video card has no HDMI, only two DVI and one S-Video.
5. I've just tried these options, and there is something! Nothing different with the intel flag (which makes sense, as there are no Intel chip on this board), but with the "nomsi" flag, it's almost running well. Now, I can use Attract Mode. But the performance is still not very good.
Please have a look at this
, to illustrate my point. You can see there is garbage on screen when switching mode, is any of this could be related to the fact I was using the Live DVD and not the installed version?
6. I didn't try to regenerate the kernel yet, could I get some performance boost from it?
Many thanks again guys, I'm feeling it's going forward.
