The name will likely contain snapshot, I think mine is ksnapshot? No, its not on the jessie install, locate is only finding systemd.snapshot, which isn't a screen snapshotter, its a systemd snapshotter > 2. Whats the magic recipe to enable AIGLX rendering on the r-pi 3b's? No such critter exists AFAIK. I'm getting an update rate in the 7 frames a second rate using the framebuffer on that jessie based install, with hdmi drive output at 1920x1024. So the backplot is often just noticeably behind the machine. You tend to get used to it. But don't forget its not running a debian kernel, and what its running is pinned. Its running kernel 4.4.4-rt9-v7+ #7 SMP PREEMPT RT, custom built for close to realtime on armhf hardware. Works ok where there is hardware step generation, and a mesa 7i90HD can supply 8 axis's worth of step generators. That depends on the firmware installed on the 7i90HD and the user can update it. It talks to this card using SPI, writing at 41 megabaud, and reading back the status at 25 megabaud. 32 bit packets per transmission either direction. Needless to say, that SPI cable is very short, nominally 1 inch. > > Thank you all. > > Cheers, Gene Heskett -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
