Via Integraded Unichrome Pro Graphics pc-1 2500 anyone tried?

[tzinternet]

Has anyone tried using the following board from Via as it has Integraded UniChrome Pro graphics??
Could this be used for a Core and/or Media Director interface.

I have seen these around the internet with a 1.5ghz CPU for less than $70.00

Feedback anyone?

I have been testing with a VIA EPIA M10000 but i am not able to get any 3d grapics to work so far i have just been able to get simple flat screens to work.

 The board is supposed to be 2d/3d capable im sure limited it is no super gaming board for sure.

 I know the driver for this chipset is supposed to support DRM and so it should be able to get some good grapics going..

This link also goes over this video chipset and talks about DRM

 The think i still have to deal with in this system is that the ubantu seems to be far behind and so if i can get this dvd install patched to a more current version of xorg and other stuff i can probably get my DRM to work and get better graphics. The kernel build does not worry me much but any building of mesa is a real pain and full of potential pitfalls that could take a working system and mess up the gui.

Well i am trying and so far its been lots of fun...

Fumbeling around using the OpenChrome or the ViaChrome driver rebuilding peices of xorg and the kernel.

I have yet to get my direct rendering working..

Ok i managed to get drm and opengl working on this system but its not very stable yet. I still have my X server crashing or freezing under heavy load.

 I followed the exact procedure as documented on a pdf at viaarena using ubuntu 7.04.

 Be warned this document has some holes and oversights its not exactly a step by step some stuff was just plain wrong so untill i resolve the stability issue i would rather not post any specific processes i changed as they are probably also wrong 

 However if you follow that procedure you should be able to get stuff working.

A few things not on that doc are as follows.

I had to modify my xorg.conf

Section "Device"
Identifier "VIA Technologies, Inc. S3 Unichrome Pro VGA Adapter"
Driver "via"
Option "DisableIRQ" "true"
Option "EnableAGPDMA" "false"
Option "NoXVDMA" "true"
BusID "PCI:1:0:0"
EndSection

Also the Driver "via" is actually "unichrome" i think but i just renambed the custom driver i compiled per the doc to via_drv.so so it works as shown.

If you build the Unichrome Pro installer from the Via sources then Xorg.conf is automatically setup for you

Care to share your xorg.conf

I have this board and I have installed the drivers per the quide.

I can run the avwizard fine, everything is great until the orbiter actually starts drawing the screen it then freezes.
Tried multiple resolutions with ui1 same problem.

I rebuilt the image and tried again ----- same problem

Any thoughts??

It might be your build of the Unichrome Pro drivers... as they are working fine under UI1 here (but not on the Via Mobo you are using it has to be said)
