Hi, I tried several distros (Fedora 20, CentOS7, PcLinuxOS, Gentoo) and I had problems with all of them. Simply, I get error message stating that desktop has crashed or AccessViolation while opening files. Could you include exact version of linux that you use? I first try with VirtualBox and Fedora 20 and Lazarus seemed the most stable on this distro. But when I installed on desktop HP dx2400 it crashed.
I'm gonna try OpenSuse and Debian 7.7.
