Dual Monitors Redux

My trusty 1050×1680 portrait monitor began resetting itself, which probably indicates failing capacitors in the power supply or logic board; eBay has¬†capacitor kits, but it may not be worthwhile fixing the poor thing. I snagged a new 2560×1440 Dell U2713HM monitor, added a dual-Displayport PNY NVS310 video card, told Xubuntu 14.04LTS to use nVidia’s binary driver, and, somewhat to my astonishment,¬†It Just Worked.

The xrandr report:

Inexplicably, xsetwacom once again expects the "HEAD-0" parameter that was "DP1" the last time around:

xsetwacom --verbose set "Wacom Graphire3 6x8 stylus" MapToOutput "HEAD-0"
xsetwacom --verbose set "Wacom Graphire3 6x8 eraser" MapToOutput "HEAD-0"

The new display presents crisp characters; seeing 140 source code lines at once is wonderful.
