Hi,
I have no hardware decoding work on linux mint 20.2 cinnamon.
Nvidia Driver version 495.44
NoMachine 7.7.4session log :

there is a problem with Nvidia driver?
Any ideas?
ThanksProblems does not looks like there is some missconfiguration or missing of some system libraries regarding the va libraries.
Strange thing is that from vainfo we have <unknown profile>.
Please can you check what is installed in relation to libva and va-api. You can do that check by executing:
dpkg -l "libva*"dpkg -l “libva*”

Hardware decoding do no work at all under Linux, same errors. With windows and NoMachine theses cards work fine.
Have you any solution? Thanks
Can you check following command
ls -l /dev/drithere should be list of devices, one of them renderD12x will be nvidia (will be renderD129 or some other number)
then run following command
LIBVA_DRIVER_NAME=nvidia vainfo --display drm --device /dev/dri/renderD129In last command we do following:
– we say to vainfo to use nvidia driver with LIBVA_DRIVER_NAME
– we specify that nvidia device should be used by selecting it manually as renderD12x
– the most important part is that it uses DRM, instead of default X11 for display argument – we need to use it that way in our softwarePlease then show us output of the mentioned command.
ls -l /dev/dri
