Detailed bug description: In Ubuntu 16.04.1 [1] on the Toshiba Chromebook 1, if you try to select text by word, by double-clicking/triple-touchpad-tapping and then dragging the mouse, this only works occasionally. However, selecting text by line with a triple-click/4-tap drag works fine. This bug does not appear when Ubuntu 16.04.1 is run in a VM in VirtualBox. [1] and now Ubuntu 14.04.5 with the hardware-specific update to Linux kernel 4.4.0-34-generic (the same as for 16.04) Steps to reproduce: 1) On a 1st-generation Toshiba Chromebook (and possibly other machines, too), run Ubuntu 16.04.1 from a boot disk (http://releases.ubuntu.com/16.04/ubuntu-16.04.1-desktop-i386.iso). 2) Open a terminal window and type several words. 3) Double-click/triple-touchpad-tap and then drag the mouse to attempt to select multiple words. 4) Compare this to the same boot disk run in VirtualBox, where it works properly. 5) Compare this to Ubuntu 14.04.5 with the hardware-specific update to Linux kernel 4.4.0-34-generic, where it doesn't work. 6) Compare this to the hardware-specific update but with Linux kernel 4.4.0-34-generic removed (downgraded to 3.16.0-77-generic), where it also doesn't work (and is therefore not a kernel problem, but rather relates to other files in the hardware-specific update). Expected results: Multiple words are selected. Actual result: Only the first word is selected. Reproducibility: Double-click drag-select will work occasionally, but most of the time it doesn't. Workaround: In applications other than Terminal, can use Ctrl+Shift+Right-Arrow to select by word (significantly slower for large text blocks). No known workaround for Terminal. Impact: Recommend not upgrading to 16.04 if you have a computer where double-click drag-select doesn't work in it.
