However, I couldn't make the brightness setting work right, as when I made the text darker, the background on the last page turned dark. By the way, I'm sure there's some place where I can make the page-left default 24 points, but I just haven't found it yet. By default, the mouse under Linux is typically much too slow, requiring large hand movements to move the pointer. This is inconvenient, and although I'm a layman with regard to ergonomics, I personally fear those large hand movements put me at greater risk for repetative motion injuries. Luckily, this problem is easy to fix.
Many people think the fix is to boost the acceleration.
That makes the mouse fast enough, but requires you to move the mouse quickly to traverse large distances, then slowly to zero in on the exact target. Not good for productivity. The problem isn't accelleration. The problem is that the pointer moves too few pixels per inch of mouse travel. You'll notice I use 1600 for the resolution.
