Does not start on Ubuntu 20.10

[llabusch93]

When trying to start VokoscreenNG on Ubuntu 20.10, it does nothing. From a terminal with, it says, there is an error:

vokoscreenNG
[1]    44123 segmentation fault (core dumped)  vokoscreenNG

The system logs have this recorded:

vokoscreenNG[43857]: segfault at 0 ip 00007fa0c8806bc5 sp 00007fffda5a1540 error 4 in iHD_drv_video.so[7fa0c86ed000+348000]

Already tried to reinstall, no success. Any suggestions?

[vkohaupt]

remove the Package intel-media-va-driver-non-free

[vkohaupt]

I see it is gives 2 Versions in "Ubuntu Software"
2.0.5 as Distributions version and 3.0.7 as snap.
Which version crash?

[llabusch93]

Hello @vkohaupt

the package you mentioned is not installed on my system:

Package 'intel-media-va-driver-non-free' is not installed, so not removed

and in fact the version of vokoscreen-ng is currently 3.0.5 in Ubuntu 20.10:

sudo apt show vokoscreen-ng                                                       ok | at 08:05:14 
Package: vokoscreen-ng
Version: 3.0.5-1
Priority: optional
Section: universe/video
Origin: Ubuntu
Maintainer: Ubuntu Developers <ubuntu-devel-discuss@lists.ubuntu.com>
Original-Maintainer: Thiago Andrade Marques <andrade@debian.org>

your log say ... error 4 in iHD_drv_video.so
Normally iHD_drv_video.so is in the package intel-media-va-driver-non-free

You must search on your system in which package the library iHD_drv_video.so is.

If you cant find this package remove vokoscreenNG 3.0.5 and install 3.0.7

Hi all, vokoscreen-ng 3.0.7 is already in Debian unstable and the link is here: (AMD64) http://ftp.br.debian.org/debian/pool/main/v/vokoscreen-ng/vokoscreen-ng_3.0.7-1_amd64.deb (ALL ARCHITECTURES) https://packages.debian.org/sid/vokoscreen-ng Regards

@vkohaupt and @andrade87

thanks a lot, installing Vokoscreen 3.0.7 from the deb package solved it. Works great now.

Cheerio!

Hmm, I am seeing the same issue as @llabusch93 : vokoscreenNG doesn't start from the graphical launcher, and trying to run it from the terminal is no good either:

$ vokoscreenNG 
Segmentation fault (core dumped)

Syslog

pop kernel: [ 8742.651246] vokoscreenNG[42607]: segfault at 0 ip 00007faa763cbbc5 sp 00007ffd6d5bc790 error 4 in iHD_drv_video.so[7faa762b2000+348000]

intel-media-va-driver-non-free is not installed:

$ apt policy intel-media-va-driver-non-free

Using Pop!_OS 20.10 (based on Ubuntu 20.10)

These logs are with vokoscreen-ng 3.0.7 from @andrade87's link (same errors on my system from 3.0.5 as well though)

Any other tricks that could be tried? Was really enjoying this software

[vkohaupt]

I found two package with the library iHD_drv_video.so

intel-media-va-driver
and
intel-media-va-driver-non-free
https://packages.ubuntu.com/search?suite=default&section=all&arch=any&keywords=intel-media-va-driver&searchon=names

what say
apt policy intel-media-va-driver

[jkarstens]

Ah, yes

$ apt policy intel-media-va-driver
intel-media-va-driver:
  Installed: 20.2.0+dfsg1-1
  Candidate: 20.2.0+dfsg1-1
  Version table:

intel-media-va-driver looks like my issue. Will investigate to see if it can safely be removed and try again. Thanks @vkohaupt !

I confirm that on Ubuntu 20.10, it is crashing with segfault when intel-media-va-driver is installed. It works fine when intel-media-va-driver-non-free is installed.

What it interesting is that it happened to be just now. I upgraded to ubuntu 20.10 a month ago and I used vokoscreenNG in the meantime. It even worked ok two days. In the meantime (between then and now), my laptop was not rebooted (it was on or in suspend mode) and I didn't do any software upgrade.

I run sudo apt remove intel-media-va-driver, it also auto-installed intel-media-va-driver-non-free. Then, the issue solved. Thanks everyone.
