  Xorg - Touch Pad/Screen loses events

Status in xorg package in Ubuntu:

Bug description:
  HP Pavilion Touch-screen Laptop...

  Technically, Xorg isn't completely freezing.  It will just suddenly
  start losing mouse events.  I normally use the Synaptics touchpad and
  it seems these have a history of problems.   Once I start losing
  events, I usually can't click on anything, or I'll move the mouse and
  get the response a few events later.   This has a touch-screen too,
  and it will have the same problem.  It's unclear if the events are
  being lost or delayed or what.   However, the system becomes unusable
  and I end up switching to a text console and killing Xorg (and losing
  everything I was doing).   Xorg restarts and then it will  work fine
  for hours.

  It would seem that moving windows around in the Workspace Switcher
  while its showing the reduced-size views will trigger this bug the
  fastest.   I usually see some Firmware errors when I switch consoles

  [10343.203992] [Firmware Bug]: cpu 0, try to use APIC500 (LVT offset 0) for vector 0xf9, but the register is already in use for vector 0x400 on another cpu
  [10343.203994] [Firmware Bug]: cpu 0, failed to setup threshold interrupt for bank 4, block 1 (MSRC0000408=0xc000000001000000)

  Dmesg also says ...
  [    0.233872] [Firmware Info]: CPU: Re-enabling disabled Topology Extensions Support
  [    0.268901] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored
  [    1.050054] acpi PNP0A08:00: [Firmware Info]: MMCONFIG for domain 0000 [bus 00-3f] only partially covers this bridge

  However, its possible that none of this is related.   I checked the
  Changelog for the latest kernel, and the synaptics driver has a few
  bug fixes (as does my wireless driver).  However, I don't know what
  patches ubuntu puts onto the stock kernel, so I'll wait for further
  instructions before trying the 3.14 kernel.
