Tested mga7-64

Installed and built into 5.10 series kernel, using graphical setup, and reboot, seems to be working fine.

Hi,
this was ok for nvidia driver, but now, if i install nvidia340-cuda-opencl, all video.mp4 with h264 cannot be play anymore, urpme nvidia340-cuda-opencl solve the problem.
example with vlc with cuda installed : main decoder error: Codec `hevc' (MPEG-H Part2/HEVC (H.265)) is not supported

when removing cuda, vlc play video, but with lag and freeze :

sorry, that's not an h264 but h265 video

Unfortunately that is out of our control as cuda bits are proprietary binary-only parts of the driver.

And since the 340.108 was released over one year ago (and basically got abandoned since then) and nVidia now officially EOL:ed this driver at end of 2020 you are basically out of luck ...

Closing this report again as it's update has been pushed.

sorry to insist, before you answer i see the folowing solution for the other nvidia driver, perhaps i don"t hunderstand very well, but the solution was only an way of packaging right?
