comment How to find all serial devices (ttyS, ttyUSB, ..) on Linux without opening them?
Too bad HAL was removed from Ubuntu (after 12.04), it had some nice easy to use tools. Does anyone know if there is a replacement to the above? But if you're on a version/distro that has HAL this looks nice.

comment How to find all serial devices (ttyS, ttyUSB, ..) on Linux without opening them?
Great tip! Unfortunately I don't think this will show built in serial ports, only USB serial ports (seen by udev when attached). I don't see anything for /dev/serial in Ubuntu 14 in a VMware VM (with ttyS0/COM1 supplied by the VM), and the udev rules (60-persistent-serial.rules) are looking only at udev devices -- I don't think udev finds out about the "built-in" ttyS* serial ports, they'll have to be tested with ioctl or similar as in the other answers.

comment Disable Mouse Movement in Tap Zones on Synaptics Trackpad
I think on Ubuntu the place to store it seems to be /usr/share/X11/xorg.conf.d/. I put an InputClass section there with MatchProduct "SynPS/2 Synaptics TouchPad" plus the other required directives to set the AreaBottomEdge setting as described in the synaptics X11 man page.
