Dealing with mouse and touchpad freezes in Linux

Sometimes the desktop in several Linux distributions freezes for no apparent reason; active windows can still be used, and the mouse pointer can be moved around, but clicking is impossible. Furthermore, your touchpad can no longer be controlled; the ‘Touchpad’ tab disappears from the System / Preferences / Mouse menu. Even if mouse functionality eventually returns, the touchpad remains uncontrollable. This extremely annoying bug occurs randomly and may last for a couple of seconds, or until you restart your X server.

If you check your system’s log after such an event (/var/log/messages) you will notice a few entries similar to these:

Sep  9 09:38:15 umbra kernel: [ 4939.006198] psmouse.c: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1
Sep  9 09:38:15 umbra kernel: [ 4939.012220] psmouse.c: DualPoint TouchPad at isa0060/serio1/input0 - driver resynched.

Basically this indicates an IRQ conflict between your mouse and your touchpad. This is a Linux kernel bug (I am currently using 2.6.28) and as such it affects most distributions. An easy way to recover both mouse and touchpad functionality without having to restart your X server is restarting the mouse driver. Run the following commands on a terminal window:

sudo rmmod psmouse
sudo modprobe psmouse

If there is no terminal window open, you can use one of the following:

  • In Gnome or KDE, press Alt + F2, type gnome-terminal and press Enter
  • Press Control + Alt + F1, login with your username and password, type the commands, then press Control + Alt + F7 to get back to X

Hopefully a future kernel release will fix this problem for good.

  12. Hi.. I’ve had the same problem… I was able to take it one step further.. I placed the following in my /etc/rc.local

    modprobe -r psmouse
    modprobe psmouse proto=imps

    this appears to permanently fix the problem….

  17. My keyboard freezes as well. I have a fresh install of Av Linux 6. Does anybody know how I can prevent the freezing? I find this very strange for an operating sustem that gets so many ” hallelujahs” for stability etc…hmmmmm…..a bit disappointing to say the least…

    I hope I get this fixed so that I still can enjoy the supposedly nice OS Linux, especially the Av variant with lots of audio and video stuff…;-)

  22. WORKED, five years LATER. I am using Ubuntu 14.10. Of course, we don’t know the CAUSE of the problem, but this temporary solution does work perfectly, and has been tested more than five times.

  29. My mouse stops working at random times, probably due to broken motherboard i/o controller (keyboard keeps working). On Win 7 mouse starts working after short time but in Linux you have to manually reload the driver. Thanks!
