it dosen't but the same fix works for the video tearing on my bay trail buggy library I guess.

And the bay trail gpu driver in 14.04 is a back port from a newer kernel so It might have something to do with that who knows.

You can plain disable backing store - no need to change libsdl. The only change is anways, that hte backing store environment variable is not read anymore.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

I think 10 EUs are fine for Lanczos 3 - will tell you tonight.

Have you tried that already?
Would be interesting for the HSW Celeron Models with 10 EUs:

Yes 2955U could do it perfectly. 576i and 720p to 1080

It works like a charm out of the box almost.
I updated to the F3 bios.
Installed ubuntu 14.04 and xbmc 13.
It plays everything I have is totally silent runs cool and the xbmc interface is fast.

Had 2 issues that took some time resolving but are now fixed.
The first one was getting my mce remote to work and the second was some tearing in the video.
The remote problem was solved with.
1. Upgrading to mainline kernel
Code:
mkdir -p /tmp/kern && cd /tmp/kern
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-headers-3.14.1-031401_3.14.1-031401.201404141220_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-headers-3.14.1-031401-generic_3.14.1-031401.201404141220_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-image-3.14.1-031401-generic_3.14.1-031401.201404141220_amd64.deb
sudo dpkg -i linux-headers-3.14.1-*.deb linux-image-3.14.1-*.deb
sudo reboot
source http://www.yourownlinux.com/2014/04/inst...linux.html


2. Using the dkms_mceusb module instead of the one builtin the kernel
Code:
sudo apt-add-repository ppa:tikhonov/fixes
sudo apt-get update
sudo apt-get install mceusb-dkms
sudo reboot
source http://ubuntuforums.org/showthread.php?t=2203116

The tearing problem was solved by doing this with-nvidia-331
Code:
sudo apt-add-repository ppa:timo-jyrinki/ppa
sudo apt-get update
sudo apt-get install libsdl1.2debian
source http://askubuntu.com/questions/450593/ho...nvidia-331

the only problem I have left is that the efi boot fails sometimes.
When I shutdown the box and start it up again or reboot I just get the efi shell with no boot options.
Shut it down again and it boots up normally.
Any one having the same problem ?

Just spent over an hour and a half reading this thread and kept thinking in my head these look like real HTPC rather than say Amazon Fire Tv. yet checked the price for one of these boards and they cost around £50. So another £50 for peripherals.

seriously everyone else is talking about arm boards at twice the cost and this for £50Huh what makes firetv more appealing than these boards? is it because it takes more effort to set one up?

Whats the catch why arn't people buying these "boards". I'm a complete noob and if I was to set one up what would I need, I read something about pico psu, I'm guessing some ram. and will a USB be fine to boot ubuntu from? and is it as easy as installing like you do on a laptop. Seriously this sounds amazing and I would appreciate someone giving kind advice. I want to learn the stuff you guys do. this thread is like where the smart folks hang out.

hjolli thankyou for your post I think I will try and buy one. would appreciate if you could do a run down of the parts you used so I know what I need. feel like a kid in a sweetshop. (coming from a guy that only has xbmc running on a pi Sad )

First you need to decide on one of the baytrail boards. Do you want a cheap or expensive one? Do you want the dualcore or the quadcore? Do you need some specific feature?
Then you need the following:

Power supply: Most of the boards require an ATX power supply. You could use a standard one, but they aren't built for this kind of board and waste a lot of power, heat and noise. So I would suggest a pico PSU or similar, which also enables you to use a much smaller case. Some cases even have one built in. Depending on the board, you may need the 90W Pico PSU or another PSU which has the 4pin ATX connector.

RAM: Most of the boards use PC3L SO-DIMMS. Those are the low voltage variants of the kind of RAM you find in laptops. They are slightly more expensive than the standard ones. But there are some boards, which allow Normal SO-DIMMS, or even the desktop kind.

Storage: You could use a USB drive, but it would hurt the performance. I suggest a small SSD which have become rather cheap lately

Case: You don't really need one except for the power button, but they are nice to have anyway. Most boards use a mini ITX design, but there are also bigger ones which are mATX.

So there is a broad range of different builds you could achive, so I will give you two examples, which I have built myself:

The first one, which uses the first available board in Germany and could otherwise be more cost effective if I had known then what I know now:
Gigabyte J1800-D2H: 61,77€
Pico PSU 90W: 29,95€
Crucial CT4G3S1339MCEU Arbeitsspeicher 4GB (1333MHz, CL9) DDR3-RAM: 34,98€
SanDisk SSD-Festplatte SATA-III SDSSDP-128G: 62,13€
Chieftec IX-01B-OP Compact Serie Mini-Tower: 26,38€
Total: 215,21€ ~300$

The second one:
ASRock Q1900-ITX ITX J1900: 77,94€
Inter-Tech E-3002 ITX Tower 60 Watt (case with included PSU): 39,10€
Crucial CT4G3S1339MCEU Arbeitsspeicher 4GB (1333MHz, CL9) DDR3-RAM: 34,98€
SAMSUNG SSD 120GB 840 EVO: 88,99€
Total: 241,01€ ~335$

Those are the prices I paid, sometimes months ago. I bought the SSDs long before I got the baytrail motherboards and used them in different builds. So expect prices to be different now, since at least the SSD prices have dropped.

If I wanted to do a minimal, cheap build, I would get this one:
Biostar J1800NH2: 47€
LC-Power LC-1340mi ITX Tower 75 Watt: 33€
2GB RAM: ~20€
Some USB drive, or harddrive you may be able to scavenge from some old computer: 0€
Total: 100€ (The amount is a complete coincidence btw) ~140$

Thankyou so much Raudi. I want the cheapest build possible. the cheaper the better. the only thing I will be doing is running xbmc and stream through addons nothing else. I think I can get the Ram sorted and the storage. But im confused with the power supply thing. the board I was going to go for was
Gigabyte J1800N-D2H which can be brought for £49
the Biostar J1800NH2 is going for around £48. this board seems to be not much stocked in the UK its mainly from outside england in europe so I dont want to pay vat and tax on top. Out of these boards which is better.

The Gigabyte seems to be more known and even in htis thread they are endorssing it. (thats what got my attention) now the only thing that I'm unsure of is the power supply. Since the only thing attached will be a USB3 for boot. the Ram and maybe a wifi adapter. I will proberly need the cheapest adaptor I can get right.

I mean the thing draws 10watt max. so I wont need anything like 60w adaptor? confused around the power supply. Thankyou so much for helping me with my first build.

One last thing It needs to be completety silent. no fan anywhere. cant I just stick a laptop adaptor in somewhere?

EDIT: just read that if you buy within EU then there is no import tax or vat. So I might consider the Biostar J1800NH2. what are other peoples opionions will it be good enough for my needs or is the Gigabyte worth the extra £5-£10

It doesn't really matter whether you choose one board or another in your case. Just use the cheapest one.
As for the power supply: You don't need the 60W, but it's hard to find something with less power Big Grin
And if you include the 12V external power supply you would need, a case including a PSU is only slightly more expensive than some kind of pico PSU without a case. So I would recommend a case with built in PSU. At least here for me in Germany it is much cheaper that way.

haha still confused will a PSU have a fan? and knowing that I need the least amount of power what am I looknig at in terms of needed watt. and If Its cheaper without a case I was thinking of just leaving it without but I've never brought a case for these boards or anything. Thanks for helping I will do some research before I ask anything else.

If I type Biostar J1800NH2 xbmc into google I dont get any links but if I type Gigabyte J1800N-D2H I get lots.
Also will this do for Ram?
http://www.ebay.co.uk/itm/2-GB-2x-1GB-PC...1c40265a0a

Also if a power supply says 70watts is that how much its doing. like the board says it uses 10 watts so if I got a power supply rated 70 watts. wheres the rest of the 60 watts. excuse me for sounding dumb.

If it takes the same ram as the nuc. I bought this one and it works fine. Although out of stock from Amazon directly. http://www.amazon.co.uk/gp/product/B005L...UTF8&psc=1

May i ask where you are getting the biostar board from. I'm interested in the same
Reply
http://www.heise.de/preisvergleich/biost...09622.html

its €47,29 which works out as £38.80 plus paypals 2-3%. I've sent them an email to ask about shipping cost to UK. I'm hoping it will be like £6 so that puts it at £45 so £5 cheaper than Gigabyte J1800-D2H. If the difference is less than £5 I might just stick with the other board since they are readably available in UK. and no have to worry about shipping it back if something goes wrong

Thanks for the RAM. will the cheap ebay one work then?

Newegg.com has a J2900 motherboard available now:

ECS BAT-I(1.0)/J2900 Intel Bay Trail J2900 Mini ITX Motherboard/CPU/VGA Combo for $119.99.

If you're wondering how the J1900 and J2900 compare:

The only difference is a bit higher xpu frequency, am I right?
But the other drawbacks (only sata3gb/s, no sata6gb/s, 1xusb3.0).
The Amd Am1 platform has more.

You asked why the amazon fire? If you are only doing xbmc, and some addons $100 gets you an amazon fire. I couldn't be more happy with the device, it has wired and wireless, no fan and 2-6 Watts. Pretty hard to beat that with other hardware for $100. It also can be a gaming box for droid games.

Most traditional PSUs have a fan. A pico PSU or similar like the one built into my case are completely fanless, since they only supply such a low amount of energy. They also require an external part which takes the AC current and transforms it to DC, like the ones for laptops, or some computer monitors etc.
The 10 Watt only refers to the TDP and doesn't equal the power intake of the processor alone. In idle, you should be able to go below 10W, but under load you should calculate with much more. And it doesn't hurt to have reserves for a harddrive or two.
