My ETPS/2 Elantech Touchpad stopped working after an update. Before a few days it worked fine, but now I can't do anything only the buttons are working. It seems to be the same problem as described here: ETPS/2 Elantech Touchpad. Buttons work, cannot swipe
I tried the solution described there, but installing the
modprobe -r psmouse and
modprobe psmouse didn't help.
I rebooted and checked if touchpad is activated in the system-settings.
Has anyone a clue where to look further or another solution?
xinput gives me the following line:
⎜ ↳ ...
⎜ ↳ ETPS/2 Elantech Touchpad id=15 [slave pointer (2)]
so it seems to be recognized.
EDIT: I also tried the solution below, but there is no
serio4 directory, only
serio1. Since the change is not permanent apparently, I tried this command (as root, didn't work with sudo):
echo 1 > /sys/devices/platform/i8042/serio1/reg_07
It executes without an error, but the touchpad still doesn't work.
cat /sys/devices/platform/i8042/serio1/reg_07 gives me
0x07 as output. Is this correct? Shouldn't be there a
1 or at least a change?
EDIT.EDIT: When the screen turns black due power saving options, it gets back to life when I touch the touchpad, but the mouse pointer is still not moving.
