I've two problems with wakeup from S4:

1.) xbmc start before Networkcard is ready so I get probkems with the libraries on my MySQL server. The xbmc.log told my "unable to open database..."

2.) The VDR can't "find" my DD CineS2 tuner card, So it didn't start. Is it possible to "re-initialize"

I know it's not HowTo relatet but maybe the is something I can change in the startup script...
Both questions aren't related to the topic. Maybe it is a good idea to keep the topics clean and ontopic.
Indeed, the first is related to the network stack being to quickly. You can set wait for network as DDD has mentioned. that works (atleast it does for me). For the second, check if the modules have been loaded and it is recognized (dmesg), if it doesn't work, it is more efficient to open a new thread.
Any issues/reason to upgrade to Ubuntu 14.10?
No - not a single one. I personally will skip 14.10 completely. 14.04 LTS + mesa utopic + kernel mainline + libva wsnipex ppa is more than utopic alone would give us.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Yes you are right, sorry!
Maybe a Mod can separate from this tread...

I've been having random lock ups when using XBMC for the past couple of months (usually a couple of reboots) fixes it. It happens 99% of the time when I start up XBMC

You are running an outdated vaapi driver (see the howto on howto update to 1.4.x). Other than that the logfiles don't show anything.

Which kernel is currently recommended and how do one get mesa from utopic?
Read some pages back - I described howto do it.

Kernel you can use 3.17.1 from ubuntu mainline. This is the version I am currently running.

I upgraded all my machines to 14.10.
He asked for a "reason" :-)

I though I gave one Smile

Edit: actually I misread the question
Hi All,

Awesome thread!

Please forgive my ignorance here. I'm a long time HTPC nut and pretty experienced with XBMC/ Kodi but I'm very new to Linux.

Reading as much of this thread as I can digest it seems that if you have a system with Intel Graphics older than Haswell then you can forget achieving anything near decent deinterlacing quality for video sources (in particular broadcast TV) as you're limited to Bob and on top of that if the source is MPEG2 the results of this are even worse than you would normally expect due to bugs in the drivers?

Is that about right or have I missed something important? Just asking because my main HTPC is pre HSW but I'm achieving pretty decent video quality running Gotham under Windows at present but was hoping to move it to a Linux distro as part of the learning curve (maintaining WAF is a good incentive to learn FAST!)

If my understanding is correct then I'll hold off until I upgrade the hardware however if I've misunderstood I'd be really grateful if some kind soul would correct me.

Many thanks,

If the CPU is fast enough, you can use Yadif deinterlacing (Deinterlace) on the CPU while still decoding on the GPU with VAAPI. Only the "gpu internal" deinterlacers won't work, cause of non working implementation on the intel driver side. Here HSW or newer is needed.

Thanks fritsch!

YADIF never looked that good under Windows (compared to DXVA) but will definately test it using instructions from the first post. Stock install and Bob was terrible (as you would expect Smile ) so if I see an improvement over that at least I know I've understood the instructions/ requirements correctly.

Thanks for responding so quickly. Much appreciated!

I upgraded also to 14.10 and noticed that text scrolling wasn't so smooth anymore. I mean Kodi's filelist's scrolling at page's end where the whole list moves up, long filename horizontal scrolling and in several other places. This was with XBMCbuntu.

I decided to do a reinstall of pure 14.04 with this thread's instructions and scrolling is now smooth again. I'll make a backup and try 14.10 update again sometime later this week.
