I googled about this graphics device and found 3 drivers that I could possibly use:
xf86-video-via
xf86-video-unichrome
xf86-video-openchrome
Which one is the driver I should use? I want a stable xorg with the maximal possible 3d support. |

Thanks for the fast answer.
I could rule out the unichrome driver (xorg doesn't work with it).
Atm I'm using openchrome - it works with glitches now and then.
Xf86-video-via won't emerge. Is this the open source or the closed source package? |
