Cursor freeze on Mint 19

Post by drwho » Fri Jul 20, 2018 9:49 am

Cursor freeze (only the cursor) -
I have a Lenovo 320 with a Synaptics touchpad.
I am running Linux Mint 19 with Mate desktop. Every day or two, the touchpad stops working. Everything else still works and I can use a USB mouse. I have not noted any commonality between these occurrences - It doesn't seem to matter which apps are open or on focus, whether or not the browser is started, or what I am doing at the time. It has happened in the email program and the e-reader as well as the browser. It doesn't appear to depend on system resources, because ot has happened with only one small application running. A temporary fix to restart the cursor without having to lose any work is ctrl-alt-del This brings up a dialog box with four options: use the left arrow key (which still works along with the rest of the keyboard) to navigate to the "suspend" option, then click it using the keyboard enter key. This suspends it. Tap the power key to resume from suspend, and everything, including your work is back to how it was before the cursor froze. In a nutshell - suspending then unsuspending temporarily fixes the cursor freeze problem.

Just an edit -
The title should be 'Touchpad freeze on Mint 19" since the entire touchpad, including the clicker buttons stops working

Your laptop may be too new for LM 19's default kernel 4.15.

Had the same issue on my Yoga-720. Solved it with the help of the mint release notes https://www.linuxmint.com/rel_tara_cinnamon.php
section Touchpad drivers -> remove the synaptics driver to revert to the libinput default.

The synaptics driver somehow messes up the touchpad.

Yes, I replaced the xorg driver with libinput, and there is improvement, but it still freezes every day or rwo

FYI - This problem is still present after installation of the new kernel 4.15.0-29.

Don't know if this is related, but the earphone jack stopped working. The same (temporary) fix that I use to restore cursor movement (suspend, then unsuspend), also worked for this problem.
P.S. Installing kernel 4.15.0-30 had no effect on the cursor freeze problem.

I have the same problem with the touchpad randomly stopping to work, although I'm still on Linux Mint 18.3 on my Asus N550JV laptop.

I found I can restore touchpad movement by either disabling and reenabling the touchpad with the Fn+F9 hardware keyboard combination, or by switching to another virtual workspace (strg+alt+right/left), although this will not restore the two finger scrolling function. For that I have to suspend the system and wake it up again just as @drwho observed.
