Re: Maus verzögert um 400ms+ und ist langsam

Interferenzen mit WiFi/Bluetooth?
Probier mal, ob umstecken auf einen anderen USB-Anschluss hilft.
Falls Du einen USB-Hub hast oder ein USB-Verlängerungskabel, versuch auch mal ob es hilft, den Dongle nicht direkt in den Raspberry Pi zu stecken.

You should remove all files from your local wiringpi build:
Start with

sudo rm /usr/local/lib/libwiringPi*
if you didn't do this already.
Then post the output of

Code: Select all

You still have shared libraries from a local build of wiringpi in /usr/local/lib... There may be also files below /usr/local/include At your own risk, try something like this: pushd /usr/local && for f in $(dpkg -L wiringpi | sed s'#/usr/##'); do if [ -f "${f}" ]; then echo sudo rm ${f}; fi; done; p...

I would then use my SSD solely as a file server (1 partition only) to my home network. I've never in the past never managed to get PiVPN working so th...
