Hey everyone,

I just brought a DN2800mt back to life, only to realize that there doesn't seem to be 2d/3d acceleration support for it.

to summarise:
- R8 32bit LXDE is running and everything is OK.  :)
- X11 is OK to boot with graphical interface, but Xrandr shows a 'default'  value with no hardware info.
- HDMI is OK to auto-detect.
- VGA output is OK but with the 'default' resolution irrespective of resolution of the plugged monitor.
- Video acceleration is (expectedly?) NOK, video up to 320p is playable but with CPU at 100%.
- The machine is an Intel Desktop board DN2800mt (Cedarview), NM10 Chipset, with GMA 3560 on-board graphics (rebrand of  PowerVR SGX 545)

I read through posts on forum for other distros and essentially there doesn't seem to be any consensus if this has or hasn't got a solution.

Any thoughts, advice, solutions?

Thank you in advance!

Anyone with similar experience? should I take it to Xorg?

BiffBaxter will be the best to answer this post. However due to his work and flights he has to make during the week, he is lagged on logging in here.


If you can bear with this thread for a bit, he should be able to help

Hi all...Quick response on this...I do not have the hardware to validate this, but read the thread below as it may help you find a solution.

Very similar to the experience we had with the Poulsbo chipset a couple years back that we eventually worked around.

Hi Biff!

Thank you for your reply on this one, I really appreciate it and I would just like to add that I have been using wattOS on other machines and I really really like it! So yeah, big thank you for your efforts and for making a great (lean!) product.

All of this is certainly out of my depth but if understand currently:

- cdv-gfx-drivers-1.0.3  only works with kernels <3.1
( https://communities.intel.com/thread/38972?start=30&tstart=0 )

- there are experimental git efforts to port it but it seems to only work up to kernel 3.9
(https://github.com/thomas001/cedarview-drm/issues)

- x server will only work with modesetting but won't support accelerated 2d
(https://wiki.archlinux.org/index.php/Intel_GMA3600#Cedarview-drm_module_port)

- a few people made reference to step-by-step instructions on installing the drivers on debian (as a patch?) but it seems to point to a 404 pdf document from Intel's servers
( https://communities.intel.com/thread/29157?start=165&tstart=0 )

It looks like like Imagination Technologies wants to lock this (4yr old!) gfx card's IP in a vault and !ntel sees the cedar trail as old dead wood (pun intended?).

>> Honest question:
Should I try: option a) venture in trying to make this driver work? option b) scavenge for a pcie gfx card that is supported right off the bat?

-----------------------------------------------
For background:
I wanted to use this board because I already had it from an old win xp desktop and from spec it happens to have really tolerant power management.
Effectively I want to hook it to a battery and use it as cheap field-test "not quite hard-real-time embedded" rig  for computer vision experiments (GTK + openCV). So 2d&3d acceleration is needed for it to have acceptable latency otherwise I am probably better off sourcing another target for these field trials.
-----------------------------------------------

As always, any advice/suggestions/ideas are welcome, from Biff, or all the other users.

I look forward to hearing from you guys

Thank you once again in advance.
