Crash: _dbus_check_is_valid_bus_name #44

Closed darren-martz closed 4 years ago

I am on Raspbian Lite 2020-02-13 on a Pi4 device. This is a fresh install with all updates completed.

I have run sudo apt-get update && sudo apt-get dist-upgrade -y && sudo apt-get auto-remove -y && sudo apt-get autoclean

Has anyone else run into this? I cannot get it to display. The setup is the default layout modified for 2x2 with new camera names, and RTP paths to (4) HikVision cameras. VLC can view them without an issue, but I'm struggling getting this setup.

I had read the following could help, but it just suppressed the errors.

export DBUS_FATAL_WARNINGS=0 unset XMODIFIERS

Yeah, of course right after spending 1/2 a day on this, posting the ticket, 30 minutes later it starts working. I tried the master branch and it just worked.
