Works with Ubuntu Linux after minor tweaking,
Verified Purchase(What is this?)
This review is from: IOGEAR 2Port USB KVM Switch+cable (Personal Computers)
First off, read the quick start instructions. Duh. Generally, a usb cable can be plugged in anywhere. This is NOT the case for the control box. There are keyboard and mouse icons that specify where to plug-in, but they are on the BOTTOM of the control box; black on black and easy to miss. This is all clear in the instructions however. RTFM.
Next, the default Ubuntu Linux 12.04 video drivers do not seem to work with this kit. I needed to install the proprietary Nvidia drivers to get it all happy. Fortunately this is easy to do from System Settings. Without them, the screens would initialize mirrored, with the common resolution being that of the lower setting. When I tried to un-mirror the screens and set the higher resolution of the external screen, it actually hung the Linux system -- a hard hang -- every time. But as I said, the Nvidia drivers seemed to avoid this issue without further tweaking.
Third, the control box seems to revert to the first position when systems are powered back on. Not a problem, but this might be confusing. Look at the LEDs on the control box before you assume something is messed up.
All in all, if you plug it in properly using the Nvidia drivers and boot up it does work with Ubuntu Linux.
I might add that you can use the switch for only the mouse and keyboard if you prefer. I have an iMac with a large screen and have not yet connected the cable for the iMac monitor to the control box; only the mouse and keyboard, and that works fine -- providing a common keyboard and mouse but two large screens. Note that some Macs may have a mini dvi port to connect to an external monitor, which will require a mini-dvi-to-vga adapter. Inexpensive and probably quite simple but i haven't tried that. Good luck!
