i'm jealous

Recommended Posts

i'm in the middle of building and testing a new high end but lowish power itx htpc for my daughter, total cost about £1000.

 

some of the parts list here :-

cpu :- i7-6700

motherboard:- gigabyte z170n-wifi

case :- silverstone mlo5b

psu :- silverstone st45sf

memory :- 2x4gb hyperx black

storage :- 2x2TB samsung m9t

boot drive :- samsung 250gb sm951nvm

tv tuner :- tbs 6205

remote :- flirc + oneforall urc-7960

 

now i've only just put it together and am still sorting out updates, software, drivers, etc. etc but am already jealous!!!

 

just ran a hdparm test to see what this new m2 boot drive can do and here's the result

 

timing cached reads: 31748 MB in 2 seconds =15903.83 MB/sec

timing buffered disk reads: 194 MB in 0.11 seconds = 1841.62 MB/sec

 

now to give you an idea how fast that is, here's my 240gb kingston hyperx savage ssd

 

/dev/sda:
Timing cached reads: 19776 MB in 2.00 seconds = 9901.56 MB/sec
Timing buffered disk reads: 812 MB in 3.00 seconds = 270.62 MB/sec

it's held back by my 3GB sata connections but even on 6GB sata i believe it maxes out at about 500 MB/sec

 

never even seen raid 0 setups come close to that 1841 MB speed.

 

going to run a lot more tests on it later to compare it to my old but high end pc but already know i really really want to build myself a new system now even though the one i have does everything that i need and is fast enough anyway. :rofl3:

it's p-ing me off big time at the moment, or i should say the new leap42.1 os is p-ing me off big time, seems to be a bug ridden load of crap to me, no idea what suse are doing but i couldn't recommend leap42 to anyone, going to install 13.2 and see if things work again.

it's supposed to be suse newest and greatest os, but to be honest it's bad enough to make me think about looking for a new operating system. :laughing:

 

going to install 13.2 at least i'm more used to that so if there are any hardware problems i won't have the added frustration of trying to find my way around a new os too.

It is a great OS Terry. Everything you are experiencing I am willing to bet comes down to a video driver. That is the only time I had any issues, and once I installed Nvidia and or AMD drivers, all bugginess goes away.

could well be bruce, after all it is a new skylake intel chip with built in gpu so could definitely be an intel driver problem, always the risk we take when building a pc with the newest hardware/chipsets with linux.

 

going to install 13.2 to check things out and if everything is ok there then i'll probably give leap another shot and see if i can sort out the problems i'm experiencing.

 

can't remember if 13.2 uses a newer kernel than leap 42.1 so might need to check that out too.

You are indeed simply experiencing graphics problems. Going to 13.2 would likely be even worse.

 

You need at least Linux kernel v4.3 to get support for a Skylake CPU, at least if you use built-in Intel graphics.

 

You can add the stable kernel repo, and install kernel 4.4 in leap. http://download.opensuse.org/repositories/Kernel:/stable/standard/

well it's been another frustrating day with nothing resolved. :laughing:

 

anyway to cut a very very long story short i now have a system with 13.2 and leap42 installed, (you wouldn't believe the hassles i've had installing 13.2, no idea what difference there is between 13.2 and leaps grub2 installation but only leaps will boot from the nvme drive.) leap42 is nothing but bugs so far, to many to mention, 13.2 works great EXCEPT!! no sound through tv hdmi connection (only way i can connect this build to any screen i have and is what will be used when round my daughters.) so working on it is a pain to start with, either sitting on the floor in front of the tv or straining to read what's on the screen from my settee. :rofl3:

 

saw a fix for 13.2 for the sound which was to update the kernel from the stable repo like you mention bruce, haven't got around to trying it yet but will definitely try it with leap42 too.

 

must admit i quite like the look of leap if it wasn't for all my problems souring me on it.

 

:b33r:

 

i'm sure i'll get it all sorted eventually. :laughing:

i can't remember getting this frustrated working on any new build before, every time i think 1 problem is fixed another shows up, that kernel update fixed most of the problems i'd seen in leap42 like failing to resume correctly after screen locking bruce but now i'm getting other problems like dolphin crashing every time i try and browse the /dev folder to try and work out why the tv card drivers won't load/work even though they seemed to build and install correctly.

 

i'm going round and round in circles at the moment with leap42. :laughing:

 

as to 13.2 the updated kernel fixed the sound issue but broke everything else (slight exaggeration) eg. no video player will play a dvd they all just crashed but think i'll go back to 13.2 and work on that for a while and see if i can get things working there, leap42 is just giving me a headache at the moment. :rofl3:

Terry, I hate to ask but have you tried wiping the drive and doing a clean install of either or both O/S's??

 

I'd be remiss if I didn't ask...

caintry i've done a clean install of different os' that many times i'm in danger of killing this flash drive before i've got a working problem free system i'm happy with. :rofl3: (not laughing at your question just the amount of times i've clean installed the os.)

last time i did a speed test on it tho. the result was over 2000 MB/s so am still awed by it's performance and want one in my next pc. :mrgreen:

 

bruce what repo's do you have installed for your leap42 system?

 

also what's your reboot time? on this system it takes nearly 2 minutes before it shuts down to start the reboot yet in 13.2 it's only seconds. (by the way using ext4 partitions now not the defaults.)

 

i've tried loads of different things even tumbleweed but can never seem to get everything working for one reason or another (same issues in tumbleweed as there are in leap42.).

 

i keep getting frustrated and walking away before my head hurts to much, gives me time to relax and think of new things to try.

13.2 works with a couple of issues, leap42 works with a couple of issues, issues different in both os so what i really need is to merge both somehow so i have a leap13.2 system where everything works. :laughing:

 

when i get back to it i'm going to add these kde repo's and see if they fix the dolphin crash problem in leap.

Version: Leap 42.1

    Extra: http://download.opensuse.org/repositories/KDE:/Extra/openSUSE_Leap_42.1/
    Applications: http://download.opensuse.org/repositories/KDE:/Applications/openSUSE_Leap_42.1/

I have

packman

libdvdcss

non-oss

 

That is all I use for any computer.

 

My boot times are faster than 13.2

that's all the repo's i usually have to except for the nvidia repo.

 

boot time is not what i'm curious about, even though the boot time is still faster for 13.2 on this system but nothing much in it both boot in seconds, 13.2 is almost instant.

 

it's when i'm rebooting leap42 it takes ages, so it's the shutdown time that is long, well 2 minutes seems long to me. :mrgreen:

i don't remember any previous os taking so long to shutdown or reboot before, at first i thought it was something to do with btrfs but now i'm using ext4 it must have something to do with the os writing files ready for next startup or something.

 

going to add those repo's now and do a dup and see if it fixes things if not then i think i'll start again with 13.2 run some tests find out what does and doesn't work with that distro and see if i can find solutions/drivers to fix that.

 

seems easier to me than starting with leap42 and trying to figure out why dolphin is crashing when entering the dev folder at the moment, wish i could make up my mind and stick to trying to solve one problem at a time instead of getting frustrated and keep swapping. :laughing:

it is the video drivers Terry. It's that simple it really is.

if that's the cause of all my problems bruce then i'm stuck up a river without a paddle coz i really don't know what else i can do to fix an intel driver problem after installing the latest stable kernel. :laughing:

You put a cheap Nvidia card in it. Then a year from now, when Intel does something about their cnstant late driver issues you can go back to the on board junk.

 

I have experienced most of what you are describing, I too thought the new plazma, dolphin, or KDE were at fault, when I installed the proper nvidia and or AMD drivers all issues went away and it ran like a champ. Then I test installed on a two year old laptop with intel, and a five year old desktop with intel and all was fine, as the older intel chips are well supported.

 

When drivers were good the desktop behaved, when using the built in kernel drivers, things were bad.

big problem with that tho. bruce, no room on itx motherboard or in the tiny case for a graphics card because the quad tv tuner is using the only pcie slot.

 

i'll start fresh tomorrow and see what i can accomplish, can't even get the tv tuner drivers to install in leap42 at the moment for some unknown reason, i could live with dolphin crashing just as long as mythtv worked but can't even get around to testing myth until i can get the tuners driver to work, just 1 frustration after another at the moment. :laughing:

ok got everything installed and working that i need on leap42 original kernel (think it's 4.1), still has issues/bugs but nothing that is a show stopper at the moment, so going to let mythtv run for a week and see if there's any issues with that, if not then i'll take it round my daughters.

 

quite impressed with the flirc adaptor too, makes setting up a remote for mythtv really simple and it works great so far.

 

even with all my issues i think i still want to build myself a new skylake system. :laughing:

yes i know i'm a glutton for punishment. :rofl3:

 

to be honest when i do get around to building a new system for myself, skylake will probably be old tech. :mrgreen:
