Problem: Underscore is not Visibile on Ubuntu With: Eclise Luna SR2, Mars 2, Neon 1a on Ubuntu 16.04 LTS After few tests I understand this  is because my Ubuntu has text scaling factor set to 1.05 (from Unity Tweak Tool) Solution #1 text scaling factor set to 1.00, but for me is too small (you need to restart eclipse to see changes when you change Ubuntu text scaling factor) Solution #2 change only the default font in Eclipse with Liberation Mono (text scaling factor set to 1.05 as default) (for me the best solution at the moment, good font, good size, system text scaling factor set to 1.05 is good also for other applications like terminal)

screen è un comando che permette di aprire una shell come fosse un servizio. Utilissimo nelle sessioni SSH quando si vuole lasciare dei comandi attivi anche una volta scollegati. Per iniziare una nuova sessione usare il comando screen a questo punto siete entrati nella console che potrete tenere attiva utilizzando CTRL+A e poi D uscirete dalla console lasciando il comando in esecuzione. potete controllare le console attive con screen -ls Ora per ri-agganciarvi a una console lasciata aperta usate scree -r <nome della console> Maggiori dettagli li trovate qui: http://linux.byexamples.com/archives/86/multiple-workspace-on-single-terminal-with-screen/
