Bug Description

Detailed bug description:
In Ubuntu 16.04.1 [1] on the Toshiba Chromebook 1, if you try to select text by word, by double-
[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://
2) Open a terminal window and type several words.
3) Double-
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 & an updated graphics stack (`sudo apt-get install $(hwe-support-
6) Compare this to the hardware-specific update but with Linux kernel 4.4.0-34-generic removed (`sudo apt-get remove linux-image-
7) On a non-working system, do a double-click drag-select with as fast of a double-click as possible. With this technique, you should be able to successfully double-click drag-select almost every time.
8) Open Gear menu > System Settings... > Mouse & Touchpad. Set Double-click to be as slow as possible. Also install & open GPointing Device Settings, and vary the Tapping tab settings. Neither of these fixes the problem.
Expected results:
Multiple words are selected.
Actual result:
Only the first word is selected, unless you double-click very quickly--much quicker than comfortable for normal use.
Reproducibility:
Appears to be "sometimes reproducible" at normal double-clicking speeds, but this is actually because you must do the double-click very quickly to get it to work.
Workaround:
In applications other than Terminal, can use Ctrl+Shift+
Impact:
Recommend not upgrading to 16.04 if you have a computer where double-click drag-select doesn't work in it.
