I ran out of crtcs, but I wanted another monitor. I widened a virtual display, and drew the left portion of it on one monitor, like regular. Then I had a crown job that would copy chunks of it into the frame buffer of a USB to DVI-d adapter. It could do 5 fps redrawing the whole screen, but I chose things to put there where it wouldn’t matter too much. The only painful thing was arranging the windows on that monitor, with the mouse updating very infrequently, and routinely being drawn 2 or more places in the frame buffer.
Companies try to maximize green per red. By paying less, and getting the same, they maximize that, year after year until (in a temporary and unforeseeable setback) you leave for… Bluer pastures, apparently.
There are different sorts of companies, and the more they think of employees as a number of years of experience plus a stack of skills, the more susceptible they are to believing that replacing humans with other equally skilled humans is a productive way to spend their time.
