sdr++ very slow to respond on raspberry pi
wptracy opened this issue · comments
I couldn't fine deb file for arch aarch64 on nightly build, so I compiled new.
SDR++ opens and runs, but is very very slow to respond.
I've attached a screenshot of the window, and the commands I used to complie sdr++ (below)
pi@64bit8GramRpiLogitecMediaServer:~ $ arch

I discovered that it works fine if the raspberry pi is not running headless with VNC.
If there is a display terminal attached, it works OK.
I ordered a Micro HDMI to HDMI Adapter to connect a dummy display, and will see if that works.
The micro HDMI to HDMI adapter and dummy display fixed the problem.
