[Qemu-devel] [Bug 1834113] Re: QEMU touchpad input erratic after wakeup from sleep

[Avi Eis]

Right now it stopped happening, although I did see something briefly
last week that fixed itself on a reboot.

If it happens again I'll check those details.

Title:
  QEMU touchpad input erratic after wakeup from sleep

Status in QEMU:
  Incomplete
Status in libvirt package in Ubuntu:
  Incomplete
Status in qemu package in Ubuntu:
  Incomplete

Bug description:
  Using Ubuntu host and guest. Normally the touchpad works great. Within
  the last few days, suddenly, apparently after a wake from sleep, the
  touchpad will behave erratically. For example, it will take two clicks
  to select something, and when moving the cursor it will act as though
  it is dragging even with the button not clicked.

  A reboot fixes the issue temporarily.
