[OpenIndiana-discuss] How is this possible? (Solved]

[Lou Picciano]

Gentlemen:

This conversation is interesting from a number of perspectives, and none of them related to OI (in my case, though they could be at some point…)

Comments about bad sync connections, lousy DVI adapters, etc. got my ears perked up. With kids forced back home last year, I’d rarely done so much intensive build/install/re-configure cycles in recent memory. Decided to do all this on an ‘easy(?)’, bullet-proof, well-tested(?) OS. Yup, Ubuntu*. Well, turns out Ubuntu is not quite so bullet-proof. And, among the problems which included variable boot results, weird boot loader setup, crazy confusion about latest Wifi hardware, etc. were the worst of all: those related to VIDEO cards and adapters. biggest single symptom was a frequent complete inability for the video adapter to ’sense’ the monitor resolution(s).

Real pain in the ass.

Always productive here, even if sometimes in serendipitous ways.

* (I avoid MS like The Black Death.)

So I am going to crush them with a 20 ton hydraulic press. If there were someone I disliked enough, I'd give them away.
