Fixes #302

Call xrandr with the --current switch, which skips hardware polling and uses the current screen configuration directly. This eliminates a long (~1.6 second) delay that locks up the system.

Benchmark of listDisplays() before:

real    0m1.672s
user    0m0.034s
sys     0m0.013s

After fix:

real    0m0.085s
user    0m0.054s
sys     0m0.033s
