[Kernel-packages] [Bug 1600371] Re: Gnome freezes for some seconds on simultaneous touch and stylus input (palm rejection fails)
** Package changed: linux (Ubuntu) => gnome-shell (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1600371 Title: Gnome freezes for some seconds on simultaneous touch and stylus input (palm rejection fails) Status in gnome-shell package in Ubuntu: Confirmed Bug description: My notebook (Lenovo Yoga S1) has a capacitive touch screen as well as an inductive screen for styluses. When I rest my palm on the screen and then hover my stylus above the screen so that the stylus is recognized and the mouse pointer follows it, and then move the stylus around Gnome seems to freeze for some seconds. The duration of the freeze is proportional to the time the notebook received simultaneous input from the two methods. "Freeze" means that the screen is not updated.

The bug does not appear with a TWM session nor with a LXDE session. Thus I think that we can safely conclude that this is in fact not a kernel bug. In my case it occurs only with gnome-shell. ** Tags removed: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1600371 Title: Gnome freezes for some seconds on simultaneous touch and stylus input (palm rejection fails) Status in linux package in Ubuntu: Confirmed Bug description: My notebook (Lenovo Yoga S1) has a capacitive touch screen as well as an inductive screen for styluses.

[Kernel-packages] [Bug 1600371] Re: Gnome freezes for some seconds on simultaneous touch and stylus input (palm rejection fails)
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
