#!/bin/bash # (c) Sean Parkin 13/12/10. xp-proj-enabler # This little enabler is intended to be called by an XP launching script. All it # does is to run an infinite print loop in a hidden dummy xterm. For some reason # this cures the choppy 'proj' rotation problem on the newest versions of X11 on # the Mac. Inclusion of the delay (i.e. the 'sleep' line) prevents this process # from hogging massive amounts of CPU time. Without it, the dummy xterm in which # this script operates wastes roughly 100% of a single CPU's worth of resources, # which gets the processor very hot, causing CPU fans to run at full tilt. With # the 'sleep' delay, CPU time for this process is typically less than ~1%, which # is unnoticeable in normal usage. This workaround is intended to be unobtrusive # and invisible. It is stopped automatically on exit from XP so long as you exit # properly, i.e. by typing 'exit' at the XP>> prompt. If you use XP on a Mac and # you have been frustrated by the poor 'proj' performance, you will be amazed at # how well this simple bit of nonsense works. For what it is worth, 'tput civis' # makes the cursor invisible. This version also writes out the number of seconds # (approximately) that XP has been running. # Note: Much of this script is superfluous - it does not need to count anything # or time anything, or hide the cursor. The only important task is to interrupt # the system periodically so that the xterm launched by XP doesn't suffer a race # condition. I also have a version in (completely trivial) python.
