This is a new oc­ca­sion­al se­ries of posts where I will share ideas for pro­grams that don't ex­ist, but should. The goal is to in­spire de­vel­op­ers to cre­ate use­ful tools that can make our lives eas­i­er. Or, more like­ly, to re­mind me about these ideas so I can cre­ate them my­self. Or even more like­ly, to just get them out of my head so I can stop think­ing about them.

Idea 1: A program that can automatically configure complex machine/monitor setups

My desk­top has mul­ti­ple ma­chines shar­ing mul­ti­ple mon­i­tors via one or more HD­MI switch­es. Those mon­i­tors are land­scape or por­trait, some are built in­to lap­tops and oth­ers are ex­ter­nal. Some are di­rect­ly con­nect­ed, some are not. A com­put­er may have be­tween ze­ro and three mon­i­tors con­nect­ed at any one time.

When they are con­nect­ed, in some cas­es, I want to run bar­ri­er to share the mouse and key­board, but with dif­fer­ent con­fig­u­ra­tions de­pend­ing on what mon­i­tors are con­nect­ed to what (say, is this com­put­er us­ing the mon­i­tor at the left of the one for the com­put­er with the key­board and mouse?).

So:

• I want to be able to con­fig­ure the mon­i­tors and their ori­en­ta­tion­s, and the key­board­/­mouse shar­ing, for each ma­chine.
• This should hap­pen au­to­mat­i­cal­ly when I con­nect a mon­i­tor or switch the HD­MI switch.
• It should start/stop/re­con­fig­ure bar­ri­er on each ma­chine.

Of course this does­n't ex­ist and is pretttt­ty hard to do.

For de­tails on how my set­up works now: mon­i­tors and kb­d/­mouse
