a bit of an annoying problem manifested after my ThinkPad x220 suddenly crashed. Everything worked perfectly before.
Now, every few minutes, an error occurs when using my trackpad/trackpoint. The errors include:
-no function at all -only right click -left click permanent or 'sticky'
When this happens, I enter
sudo modprobe -r psmouse sudo modprobe psmouse
After which, I can use it again... for a few minutes (or longer, if I'm lucky).
I've tried following advice at other forums, including entering
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.proto=exps"
which didn't seem to have an effect (apart from an undesirable one, that I cannot turn off the touchpad to use only the touchpoint 'nipple' in the middle of the keyboard, as they now seem to be treated as identical).
I would very much appreciate any help. Thanks :)
