(Get the code!)
I just installed this kernel and rebooted:
3.12.0-999-generic #201309190446 SMP Thu Sep 19 08:47:59 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Guess what. It worked (for the most part). The USB-VGA monitor showed up in Ubuntu's Display manager and I was able to run all 3 monitors at the same time. However, after adding this third monitor (using the SIIG USB 2.0 to VGA Pro), my second monitor can no longer get 1920x1080 resolution. For them all to work at the same time I had to set the resolution like this:
1440 x 900 - Laptop's Native Monitory
1440 x 900 - Laptop's HDMI Port's External Monitor
1152 x 864 - SIIG USB 2.0 to VGA Pro Monitor
Before adding the SIIG USB 2.0 to VGA Pro Monitor, I had the two monitors set like this:
1440 x 900 - Laptop's Native Monitory
1920 x 1080 - Laptop's HDMI Port's External Monitor
The SIIG USB 2.0 to VGA Pro is capable of higher resolutions, but when I choose them, my other two monitors turn off.
Likewise, if I turn my HDMI monitor back up to 1920 X 1080 it turns off.
