Touchpad Error (Cypress PS2) Unable to initalize Cypress absolute mode

I recently purchased a new laptop (the model number probably isn't going to help a great deal here, as it is a South African laptop -- the Mecer A21R).

I installed arch on it, and everything seems to be working fine with the exception of the touchpad, which only  registers attempts at moving the cursor as double or single clicks -- the pad is a Cypress PS2.

dmesg gives the following error repeatedly

  [  345.830621] psmouse serio2: cypress_ps2: Reconnect: Unable to initialize Cypress absolute mode. 

I have synaptics (70-synaptics.conf) installed as well as libinput [(60-libinput.conf). I have attempted to operate the mouse without the synaptics conf file, but I still experience the same problems. Here is my full dmesg output, xinput, Xorg.0.log and xinput query-state.

Any assistance would be very much appreciated!

Re: Touchpad Error (Cypress PS2) Unable to initalize Cypress absolute mode

Make sure are using the latest bios/uefi/firmware as those can contain fixes for weird problems.

Try using only xf86-input-libinput, uninstall every other xf86-input-* if you don't need it. Delete or rename any extra configuration files you may have added in /etc/X11/xorg.conf.d/ then reboot and check if it works.

If it doesn't work read this [1-2], which you could have probably found in less than five minutes if you googled for "psmouse serio2 Trackpad at isa0060/serio2/input0 lost sync at byte 1". Even if the solutions don't work for you they can most probably point you in the right direction. If nothing works and you can't get help here, then you should ask help upstream.

Also make sure to read Code of conduct

Re: Touchpad Error (Cypress PS2) Unable to initalize Cypress absolute mode

Thank you for the reply. I apologise for the negligence on my part -- I did several searches, but overlooked that one for whatever reason.

I have removed all other xf86-input drivers, but this doesn't have any effect on the situation. It would seem that any movement on the touchpad is recognized as either a left or right button click. Here is the libinput-debug-events with movement on the trackpad and then a USB mouse.

event9  POINTER_BUTTON    +7.16s        BTN_RIGHT (273) released, seat count: 0
event9  POINTER_BUTTON    +7.19s        BTN_LEFT (272) pressed, seat count: 1
event7  POINTER_MOTION    +7.96s          3.99/ -2.18
event7  POINTER_MOTION    +7.96s         45.18/-20.85

I have also attempted the modprobe commands suggested in [2] as well as the creation of a .conf file in /etc/modprobe.d with

options mousedev tap_time=0
options mousedev xres=1920
options mousedev yres=1080
options psmouse resetafter=0

This didn't help matters either.

You may have to try passing options to other modules as well, such as the i8042 module. If nothing works and you can't find any clues by searching for people with similar problems and they solutions that worked for them your best bet may be to ask upstream, either on the appropriate mailing list or by opening a bug report on the kernel bug tracker.

Sorry for the delay! I still haven't gotten things working. I may have to contact upstream. I will update everyone if I get a fix!

Thank you for your help!
