[Bug 1694225] Re: [Thinkpad T450s] Click lock effect on trackpoint left button when touchpad is disabled
Rashi, in order to allow additional upstream mainline kernel developers to examine the issue, at your earliest convenience, could you please test the latest mainline 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 mainline kernel, please comment on which kernel version specifically you tested. If this issue is not reproducible 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 issue is reproducible with the mainline kernel, 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. It is most helpful that after testing of the latest mainline kernel is complete, you mark this report Status Confirmed. Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available.

[Bug 1694225] Re: [Thinkpad T450s] Click lock effect on trackpoint left button when touchpad is disabled
I have the same problem on a ThinkPad Yoga 14 20FY. I can reproduce it with the touchpad disabled as described in this report. However, I find it much easier to reproduce (nearly 100% of the time) with the touchpad enabled, as follows: 1. With my left finger, hold down the trackpoint’s left button. 2. With my right finger, move the pointer with the trackpad. 3. Release my right finger from the trackpad. 4. Release my left finger from the button. The button has become “stuck” down! 5. Put a finger back on the trackpad. Now the earlier button release gets recognized. evtest on the trackpoint (ETPS/2 Elantech TrackPoint) shows that the trackpoint knows the button is pressed at step 1 and released at step 4, but evtest on the touchpad (ETPS/2 Elantech Touchpad) shows that the touchpad thinks another copy of the button has been pressed at step 1 and not released until step 5. The problem is still present in kernel 4.12-rc6 from the mainline archive. (I haven’t been able to figure out if enabling the new drivers in 4.12 is supposed to require manual configuration, but simply booting into the new kernel didn’t fix it.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1694225 Title: [Thinkpad T450s] Click lock effect on trackpoint left button when touchpad is disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1694225/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
