Don't run zoom as root, that's just silly. https://en.wikipedia.org/wiki/Principle … _privilege

launching 'zoom' as regular user didn't work at first, but after a system reboot, i was able to launch the app from command line, no additional info was displayed once zoom was started from CLI though.

The issue remains:  live video in full screen mode lags, if i scaled it down, the video quality improves. and the menu as well as fonts display disproportionately large on the screen.

I was able to go into settings to get sound output once i logged in.

The system is a HP desktop with intel i7, 4G RAM, and nvidia 9300 video card.

Also you've truncated the line that gives your PC spec. How much memory do you have? I have 8GiB. Zoom only seems to be using 57 MiB idling but I don't know how much it uses in a live session. I'd expect it would also use quite a bit of graphics memory.

Probably worth checking whether when zoom is active it's not driving you into using swap (disk) memory.

no sound

Do you have PulseAudio installed?

If not, do you use apulse instead?; if so, you ned to launch your binary with apulse binary

The Zoom .debs work fine for me under Debian buster, even when run in a (KVM) virtual machine. I would be surprised if Devuan beowulf behaved differently.

You should probably share the exact URL from which you downloaded the package so that we can confirm you have the correct version.

Do you see any error messages if you start Zoom from a terminal?

this is the link i used to download binary package:

does anyone have similar problem with using Zoom in Beowulf?
