Choppy 4k videos and abnormal CPU usage - Nvidia GT 1030

Post by elleeffe » Fri Sep 21, 2018 6:17 am

Hi all,

I've just recently set up a home PC with Mint 19 MATE on a Mini ITX motherboard with integrated graphics and GT 1030 video card, to be used as a workstation and media center. I've had some experience with Ubuntu in the past, but I'm still quite a newbie.

At first I ran into some big problems after installing the nvidia-390 drivers: the screen would not turn on ("no signal"). I managed to solve this by adding the following line to GRUB:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="nouveau.blacklist=1 quiet splash"

Without this line, at reboot the nouveau drivers would be installed every time. I'm not sure this is an ideal solution.

Now everything seems to work fine, besides some tearing when moving the windows around from time to time.
However, I run into major issues when trying 4k videos playback/stream. The video output is very choppy, while there are no audio issues: this happens both on youtube videos and downloaded videos. I tried Firefox, Chromium and media players such as VLC, mpv and SMPlayer: non of these gives great results (VLC is by far the worst media player, with images remaining still fo 10-20s at the time).

I must add that there are some rare youtube videos that give a much better result, though not yet 100% choppiness-free.

Here are some outputs that may help:

The nvidia graphics drivers are loaded and the Nvidia X-server settings configurator works fine, as far as I can tell.

nvidia, 390.48, 4.15.0-34-generic, x86_64: installed
As soon as I play a 4k video (to a much lesser extent this happens also with HD videos), both cores temperature shoots up to around 60°C and CPU usage goes well above 80% (up to 98%). Here is an example of the temperatures increase while playing a downloaded video:

The two peaks are two different tries, with different players.

I searched in the forum, but I could not find a fully comparable situation being described.
Thanks for the help already!

I really don't wish to appear rude, but honestly, what else did you expect out of that nowadays-woefully-inadequate-for-anything-other-than-basic-browsing-and-email machine? That tiny thing is simply not capable of what you're asking of it, so it's no wonder that the CPU spikes the heat up high then goes into cardiac fibrillation.

Well, I got it for free from our IT dept. so I wasn't really expecting anything too fancy from it :D
However, the same machine (without external video card) was able to drive a 70" monitor under Windows 7, so I assumed it would have been capable enough...and consequently imagined something went wrong during Mint's installation. I never had a UHD monitor before, so I'm not fully fully familiar with its hardware requirements.

If you confirm that software-wise there are no issues, I'll be on the market for a more capable MB!

Mint will do what you want, no questions asked, but the limitation is the hardware. You verified that yourself when you said some 'rare youtube videos' played ok but with a bit of choppiness. I'd also verify that the GT1030 video card will support full screen 4k playback.

Cheers.

Will do, thanks! The video card is indeed an entry level one, but from what I read in other forums it should be good enough, except when it comes to gaming.
