Rise Vision currently only supports Ubuntu 14.04 LTS. Now that the newest long-time-support Ubuntu version has been released - Ubuntu 16.04 LTS, does Rise Vision currently have any plans to move their development to Ubuntu 16.04 LTS, or even support it concurrently to 14.04?

If there are plans to support Ubuntu 16.04 LTS, do you have a rough timeline?

Hi Nathan,

Testing 16.04 LTS is definitely in our backlog of stuff to do, but since 14.04 LTS is supported until 2019, testing 16.04 is not a priority at this time. We will announce to everyone once testing has started and how it is going in here for sure.

Thanks!

Nathan,

While we haven't begun testing on Linux 16.04 LTS, please feel free to go ahead and install the Player on 16.04 and let us know how you make out!

I'm testing with Ubuntu 16.04 on Intel NUC5i5RYK. The reason for the test is that I experienced kernel freezes serveral times a week with Ubuntu 14.04 and I skipped the idea of upgrading the kernel in 14.04 for proper HW support for my NUC5i5RYK. I can feedback my observations in a couple of weeks from the my testing with 16.04 and a very simple presentation that only includes the image widget and images in the rise vision storage.

Thanks Jocke!

How is the testing of 16.04 going so far? We have 16.04 on our Uptime wall to do some testing with, and so far we haven't had any noticeable issues.

The install shell script installed Rise Player despite some errors that where shown in the terminal window in which the install script was running. At the end didn't the shell script terminate properly but the Rise Player was launched and everything was running fine even after the device had been restarted. The Player is restarted every night a 3.00 AM and it has been up and running fine.

The presentation which we use is very simple. It is only a couple of images that we loop through. The images are pulled from Rise Storage.

The only problem occurred when our WiFi network was down. The Player continued fine even though that there was no network connection, but after the nightly restart was the Player stuck due to no network connection. The Player repeatedly restarted since there was not network connection since Ubuntu failed to re-establish the WiFi connection even after the WiFi network was up. I had manually re-connect to the WiFi network but after a restart the device and then the WiFi connection was re-established fine and Rise Player continued as it should.

Apart from the above is everything so far running fine and kernel freeze we saw with Ubuntu 14.04 is not seen on 16.04.

Hmm...that's frustrating. does the wifi go down every time the device restarts? Or was it just that one time?

Sorry for not being clear on this. The problem to connect to WiFi was only in conjunction with that our WiFi network was down, so it was just that one time. In my experience the problem to connect to WiFi even after the WiFi network was up is an Ubuntu issue.

I however got the impression that the Rise Player was stuck trying to connect when there was no network connection. I thought that the Rise Player would continue and play from cache (but this might be a misunderstanding on my behalf).

Yet another week of the NUC being up and running on 16.04 without any issue :-). I'll simply stick with 16.04 since it appears to be stable enough on the HW that I'm using.

Is there any performance differente by using windows 10 VS Ubuntu 14.04 regarding performance with rise vision on intel compute stick? how about gpu hardware acceleration?
So far I have only used Windows 10 with the intel compute stick and if we decode the mp4 h.264 correctly in 1080p it only uses around 6-7% of the cpu which is extreme good in my opinion.

Linux has a bad habit sometimes of not being on the same level as Windows with graphics drivers, so my only worry is you MIGHT find some video quality degradation when running Linux on the Compute Stick, specifically if the videos are 1080p.

What I would suggest is running Linux 14.04 off a USB Stick that is connected to the Intel Compute Stick. This way you don't need to wipe out Windows, you can try Linux right from that USB stick.
You can see the difference between Windows and Linux hardware acceleration support on your hardware by going to chrome://gpu on each OS.

I've (finally) deployed a test unit on 16.04 as well.

I was also experiencing some kernel freezing on my NUC5i3RYH's pretty frequently (sometimes a couple of times a day) as Jocke has mentioned so I'm also wondering if 16.04 will fix it without having to start building my own hardware!

My test presentations will be moderate - mostly just images and videos but will occasionally have a couple of webpages with some javascript plugins as well.

So far so good, but I'll update here if I have any issues.

Our currently deployed fleet runs on IYE and DYE Intel Nucs and ubuntu 14.04

We are exploring some options with a new generation of hardware for our displays. We do not want to begin deploying 16.04 if it is not supported. On my bench test 16.04 seems to work well with risevision, but I am concerned that it will break with updates until official support is behind it. 

The downside to 14.04 is that it seems to have some issues running on the newer Intel NUCs (SYK), we get a lot of screen tearing on our animated content. We would need to deploy 16.04 to support the graphics of the SYK to take advantage of the newer hardware. 

Is there any news or timeframe on supporting 16.04? 2019 seems much closer now, and we would like support for our next generation.

Hi Alex, we've been running Ubuntu 16.04 on our Uptime wall for 6+ months and Rise Player is stable. I think you are safe to use it, but let us know if you see any issues.

In the coming months we'll evaluate setting 16.04 our officially supported version. 

Thanks!

Alex, when you say Intel NUCs (SYK) ... are you referring to the Skylake line of processors?

I am referring to this NUC in particular. Has incredible GPU power compared to previous NUCs, and the best form factor yet.

Hi, I am not new to Rise vision, just new to the forum.  

I wanted to add my $0.2 on the Ubuntu version topic. I have been running Ubuntu 16.10 for about 4 months.  I have two NUCs and some old HP small form factor units for players on my network.  I also have a few Kangaroos running Windows 10 on the network.  I have not had issues with Ubuntu 16.10 so far and I am pleased with it.
