Can you try

$ cat /proc/sys/vm/swappiness

to see what it is really set to?
Zero, as it has been set.

I've also tried to set /proc/sys/vm/vfs_cache_pressure to 50 (minimal value, default = 100, max = 200) without success.

On Stretch and Jessie this all worked as it should.

How eager or lazy the kernel is about writing to swap can be configured using the swapiness parameter as $ sudo sysctl vm.swappiness= n where n is an integer between 0 and 100 and 0 means no swapping ever. 1 means swap only if necessary. 60 is the standard Linux default. 100 means as much as possib...

Re: Python and Idle

There's a much better solution: install the extension package idlex which has everything which idle is missing including line numbers. And you do not have to upgrade any Python version.

You'll need a shielded USB extension cable for each USB dongle.

Something like OpenWebIf with Enigma2.
