Fldigi under Wayland causes crippling CPU-usage (RPi 8gb) #102

Closed NullVibes closed 1 month ago

On a RPi-8g, Fldigi under Wayland causes CPU-usage to spike significantly, and makes the RPi unusable. To troubleshoot, Conky cron job was #'d and the process killed manually, AND SwapFile was increased from 100M to 1GB, with no effect. A quick Google search mentions this as a known CPU issue and not memory.

The resolution was to use the Xorg window manager, and not Wayland. Use sudo raspi-config, option A6, to revert back to Xorg. Under X, fldigi works great, even if you configure an absurdly large waterfall size (like I do.)

closing issue and leaving documentation label so it can be referenced as needed.
