Have used Airclient on various flavours of Deb6&7/Ubu12&14 and had no problems whatsoever. I have always found mono quite resource intensive, but have just put it down to the nature of beast (portable libs) Since installing a fresh UBU 14.04 with unity default desktop the system (8core16GB) grinds to a halt soon I run client. System become totally unresponsive. Client solders on and eventually connects. Killall mono recovers system stability. Any one had any similar problems with client or mono on Ubuntu 14.04? Cheers Flo
