[Bug 1553811] Re: Thinkpad T460: Trackpoint mouse buttons instantly generate "release" event on press

 

Ryan, thank you for reporting this and helping make Ubuntu better.

In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  Thinkpad T460: Trackpoint mouse buttons instantly generate "release"
  event on press

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When using the trackpoint mouse buttons on the laptop, when any of the
  buttons are pressed a release event immediately follows, even if the
  mouse button is being held down. This prevents moving of windows,
  typical drag & drop operations, selection etc with the mouse.

  Example output from xev for button 1:

  ButtonPress event, serial 40, synthetic NO, window 0x7e00001,
      root 0xb6, subw 0x0, time 1097221, (116,59), root:(116,142),
      state 0x0, button 1, same_screen YES

  ButtonRelease event, serial 40, synthetic NO, window 0x7e00001,
      root 0xb6, subw 0x0, time 1097229, (116,59), root:(116,142),
      state 0x100, button 1, same_screen YES

  Button 2:
  ButtonPress event, serial 40, synthetic NO, window 0x7e00001,
      root 0xb6, subw 0x0, time 1100941, (116,59), root:(116,142),
      state 0x0, button 2, same_screen YES

  ButtonRelease event, serial 40, synthetic NO, window 0x7e00001,
      root 0xb6, subw 0x0, time 1100941, (116,59), root:(116,142),
      state 0x200, button 2, same_screen YES

  Button 3:
  ButtonPress event, serial 40, synthetic NO, window 0x7e00001,
      root 0xb6, subw 0x0, time 1098467, (116,59), root:(116,142),
      state 0x0, button 3, same_screen YES

  ButtonRelease event, serial 40, synthetic NO, window 0x7e00001,
      root 0xb6, subw 0x0, time 1098477, (116,59), root:(116,142),
      state 0x400, button 3, same_screen YES
