** Description changed: (also on Linux kernel bug tracker at https://bugzilla.kernel.org/show_bug.cgi?id=153871) 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 (see comment #23 & http://wiki.ubuntu.com/1404_HWE_EOL), 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). + 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-status --show-replacements)`; http://wiki.ubuntu.com/1404_HWE_EOL), where it doesn't work. + 6) Compare this to the hardware-specific update but with Linux kernel 4.4.0-34-generic removed (`sudo apt-get remove linux-image-4.4.0-38-generic linux-headers-4.4.0-38`), where it also doesn't work (and is therefore not a kernel problem, but rather relates to other files in the hardware-specific update). + 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. Reproducibility: - Double-click drag-select will work occasionally, but most of the time it doesn't. + Double-click drag-select works only if you double-click very quickly--much quicker than comfortable for normal use. 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. + In applications other than Terminal, can use Ctrl+Shift+Right-Arrow to select by word (significantly slower for large text blocks). For Terminal, do a double-click drag-select as quickly as possible and it will usually work. Impact: Recommend not upgrading to 16.04 if you have a computer where double-click drag-select doesn't work in it.
