Hi all,
I tried to use DirectFB with an Epia EN box with CN700 chipset.
(Ubuntu Breezy kernel 2.6.12.9)
Here is some results I got:
1) "Official" Via driver "Linux-FBDev-kernel-src_2.6.00.02":
For DirectFB I added the PCI ID of the CN700 (0x3344) in unichrome/uc_probe.h
The "DirectFB-examples" from CVS are working (or seems to) but nothing seems
accelerated.
Needed to add accelerator ID (77?) in the driver ? Hum ..., surely more needed.
Here is some outputs:

2) "linux-viafb" driver from DirectFB CVS:
I added the CN700 PCI ID in via_fbobj (and in unichrome/uc_probe.h).
After I modprobe viafb (I loaded fbcon before), I have "Input Not
Supported" message from the monitor and no display.
Here is the info I got fromm ssh:

After I did "fbset 800x600-60" I still have the "Input not supported"
message and no display.
