One Fedora 17 Box up to 16 USB Multiseat Terminals

Fedora 17, as shipped, supports only 7 or 8 plug-and-play USB terminals per machine. The cause is the kernel evdev driver’s limit of 32 input devices.

Fedora 17’s Secret Turbo Boost Button

Fedora 17’s out-of-the-box plug and play USB multiseat is awesome for sharing one system with many users — but there’s a way to dramatically boost performance and scalability, by changing the Fedora defaults.

Howto: DisplayLink USB Single Monitor on Linux

Unfortunately, Linux doesn’t support multiple graphics adapters the way Windows does, which means you can’t just plug in USB graphics adapters and expect them to extend your desktop (the good news is there is progress on this support). What is possible, however, is running a single DisplayLink adapter, or several with a Xinerama or multiseat […]
