Just so I know, is there an xorg.conf equivalent of the "-sharevts" cli parameter? I see (but haven't tested) a "DontVTSwitch" documented, which I assume is the equivalent of "-novtswtich". But I haven't seen anything for "-sharevts".
It's not a huge deal either way. Just a personal preference to have config files vs cli params. Thanks, Lloyd On 01/20/2016 04:57 PM, Lloyd Brown wrote: > Wow, Aaron.
