Well, after today I am ready to rip it back out and go back to an x86 based system. 1. much more so on its own console, but occasionally from here, the keyboard either goes dead for some random amount of time, which I think might be related to mouse pointer position AND somewhere its set for focus follows mouse. Its better from this keyboard than any keyboard attached to it because I don't think the mouse pointer position counts. 2. after setting a root pw so synaptic might work, things are so screwed I'm tired of beating my head and back up over it. 3. After trying a 2nd brand new keyboard and mouse and getting the same results, much worse with x installed, I am convinced that the armhf version of xkb is one busted piece of S---. I just spent much of an hour trying to add 9 lines to the halfile to enable 3 outputs to control the vfd, and failed. At the moment I cannot login from here because I was dumb enough to tell raspi-config to wait for a login before starting the network. And because of the poor keyboard response, its impossible to type my user pw because it will either skip characters, or go wild because it missed a key-up event, and despite setting the repeat for slow and slower, it will go off and put 50 characters of the last key pressed into whatever I an editing before I can react and tap a different key. Continueing at 50 chars a second until I hit another key. Then if I try to backspace over the extra characters, like as not the backspace key will hang and erase not only what I was typing, but 4 or 5 lines of a hal file that was already there. Anyway, its essentially bricked now until the sd card is re-imaged. And I had just added it to amanda's nightly backup duties early this morning, so the backup is no good either since the first one won't be, no network. I might be able to work around it IF the term was terminal-4.8, but its not. I've tried every terminal in the menu's, and none of them are big enough to be usefull as a default, and none have a resize drag border or corner, I tried all 3. Postcard sized doesn't cut it. So, one question, will the udoo service the 7i90HD over an SPI connection? If it will, I might blow another $150 trying it. The extra 60 is like doing an engine swap, where 50 years ago it was a given that you bring the engine, and the adapter kit, the torch with full bottles, and $500 (in 1955 money) for the other stuff it takes to make it all work.

Flooding > them with oil keeps the water out. I know that too haveing soaked my arms in the askarol or whatever pcb was in them, repairing burned up connections 18" under the oil's surface, once in a 250 kw rated box, probably north of 10,000 lbs. 3 times in my broadcasting career. You shower daily, and you still stink for about a month afterwards. I started my youngest while I still had some of the smell on me. Getting him, born deaf and on predigested formula for the 1st 5 years, up to his teen years took quite an effort. Now at about 40, he eats what he wants, and much to the surprise of the docs at the Mayo Clinic, he now hears at least as well as I do. I will always connect the dots on him getting started, and me being contaminated with that crap. > It is only the wire insolation > might care or not about oil. This wire is stranded, so no varnish. Lose the vinyl and its toast. So I'll not putz with this, but work on the hardware until the orangepi gets here. I'll redo the u-sd without x, and see if I can ship the x stuff to the Orange-Pi-3 for rendering. At that point I'll need a fresh recipe for building the u-sd card(s), I still have 2 virgin 32GB cards in the blisterpack. [...] Thanks Chris.
