just got my N-2

Unread post by phaseshifter » Thu Mar 14, 2019 12:24 pm

i`d just like to say i have my N-2 ...i did not even know it had developed..

started to just get back to the key-b..however i`m late after everything seems too be done with it ..

i must say the cpu seems more in a fashion to be more in line with a C-2 could have very-well been an C-3 board ..

still after i loaded the desktop gui it seems quite snappy in opening pages.. etc..etc

but still quite a nice board....

Petitboot still awaits. I've been busy with other things, but hope to return to n2 soon as well.

well we have the "spi" onboard so we @maddy were working with the chip i guess i was not always 100% what we were doing..

however it would be nice to utilize the chip since it looks like future boards will have it implemented as a guess"calculated"....

i look forward in participating with the users and the chipset..

Video rendering and decoding is not yet implemented for ubuntu, so performance is not that good yet.

well today i installed kubuntu-desktop boot up time seems a little slower than mate but i did find some nice tweak`s like turning of the screen locker and so on

it is more ram hungry than mate it seems to idle around the 1Gb mark...have not monitored it specifically....

sitting here after a fresh flash on a red 16Gb chip,,so i did from the minimum image ran the usual update ..etc..etc...next step ..

I installed kubuntu-full,,..took about 1/2 an hour to come down the line and install...took another 15 mins to do the setting`s and final install

so sitt`n here playing tunes ..it`s all good ..running sddm as my greeter..seem`s to be ok has not crashed or wanting to send bug reports audio out via the 3.5 phono jack works ok 4 me atm ...

let the games begin..tunes ulla cart odroid...steams nearly as good as my N-1..as per usual
love my tunes..

it`s a little ram hungry varies between 1,2 gb and 1,5 gb...
have not played with the core speeds as yet..next on my list

lets crank it up a bit...need to reboot ...update`s ...

seems a we bit slow at closing windows...i should say they fade it`s noticeable but however being a fan of the kde for many years,,,
ever since i played with red hat days
prolly was there first release as i used to buy the mag`s that came with cd`s..yes cd`s not dvd`s as quite a lot of disk`s i get are dvd`s in the mag`s these days
anyway i await better video drivers as most users are
with the N-2...even my N-1 wont come to the party with the full version of the kde/kubuntu..however you like too look at it...seems the N-2 does out rank the N-1 in many instances ...gabba..gabba..

I have recently switched distros on my desktop PC from Mint Mate 19 to Xubuntu 18.04. It boots to a desktop with only 485MB RAM used. When I open Firefox it more than doubles my memory consumption. ;-) I will try switching my XU4 to it as well. When I get an N2 I'd lik eto see an official Xubuntu image if possible.

The easiest way for me it to use "tasksel". Just do sudo tasksel and then select the tasks you want to install or uninstall. See also:

Since most of the Ubuntu code will stay the same no matter which DE you use there will not be a lot to test. It is good enough to know that it works well and is just as light weight in ARM as it is in x86_64. If you want to keep it installed along side Kubuntu you and choose between them at the log in screen.

XFCE i think it`s called the opp system at present loaded and with this Firefox session open it`s idling around 30 deg`s..now for some yooutube ...

45000

after about 10 mins of full screen utube 80`s rock music playing..so really it did not seem to go much over that mark..

==================================================================================================================

Xubuntu session....all below sentences


35-37000 a couple of windows open utube in full screen..

so with fullscreen does not seem to go over 45000 mark..15 min`s or so i guess it`s around here


===========================================================================================================================


the system up time now is 1:30...and been running multiple windows and utbe 80`s rock..i have not noticed it much over 45000 so i guess there is your heat question..xubuntu..xcfe seems around the same temp`s..passive heat sink only stock with the one it comes with
================================================
uptime now is 2:40 and i have not seen it over 45000

===================

xfce does not seem any different to Xubuntu session..as far as i can tell it maxx`s out approx 45000

@mad_ady was it of your/others opinion`s that xfce and kde and xubuntu and Ubuntu would respond differently temperature wise.. ??????

deskop`s being lighter in weight i guess i gather xfce is the light`st in weight..???. making a difference in processor load would play a part in temperature i guess...

It's my opinion that XFCE will use less RAM than KDE. I don't think you will find a measurable differrence in SoC temps because desktop environments by themselves just don't add enough CPU or GPU usage. You most likely will not even see a measurable temperature change between Firefox and Chrome because the underlying video and audio codecs should be the same.

Yes, I agree. I was curious how hot it would get at unaccelerated media playback. 45 is cool. My C2 idles at 45 and gets close to 80-90 while playing unaccelerated youtube, so quite an improvement to the C2.

Since the N2 should have OpenCL support built in could you test LuxMark and give us the scores? That would be something a few people would like to know,

First do:

Code: Select all

sudo apt install freeglut3 ocl-icd-libopencl1
Then go to http://wiki.luxcorerender.org/LuxMark#Binaries and download the Linux 64 bit package. Extract it and open a command line. Change to the directory you extracted luxmark to. Execute ./luxmark :-)

Aren't those AMD64 binaries? I don't think they are going to work and the source will need to be compiled.

You are right. Those are for AMD64. I guess the only way to do it is to compile from source.

I have tried before, it requires LuxCore/LuxRender to be compiled first before LuxMark. They create a static build and compile all the dependencies from source. After hacking their script and doing some other symbolic links, I got about halfway but couldn't get past one of the dependencies. Still on my list of things to look at but ran out of time. It would be a nice app and benchmark to have but not an easy build on ARM.
