I'll try to bring my own contribution, as I searched for 2 hours. I think I just figured out how to solve the problem, I just got it. But my solution is a bit more simple I guess:cd /usr/share/arduino/lib
sudo cp librxtxSerial* ../
In case anyone is wandering, the correct incantation is 'systemctl hibernate'.https://wiki.archlinux.org/index.php/Sy … managementPSA: Searching the wiki for 'hibernate' points to https://wiki.archlinux.org/index.php/Pm-utils , which reportedly needs some updating wrt systemd.I know nothing about hibernating, so if someone could help, please contribute.
For me swap is useful: I have 3gb ram and 2gb swap (OCZ SSD),I can still use the system with a bit of lag with the swap almost full (fiefox opera with a lot of tabs,amule,thunderbird,amsn etc... with many days of uptime). HD swap would be deadly slow instead.
