[Openchrome-users] issue on VIA EPIA EX10000EG using openchrome

Tue Nov 20 15:41:12 PST 2012

Installing the Arch package for the "old" driver 0.2.906 fails because
it expects an older version of X.
So I downloaded the source to compile it myself. Alas.
There is a file 'via_accel.c' that expects xaalocal.h, but that file is
not there in the X development files.
I figure this has to do with dropping XAA?
Any clue as to how to work around this error?
Thanks,
Willem
