ubuntu mate touchscreen and popos 22.04 issues

[hxc-gxc]

Hello there

I'm trying to install ubuntu mate on my GPD pocket 3. If I respin an image like 22.04, when I am running the live USB everything works but if I install the distro everything works except touchscreen which seems to be inverted. It is the same with the preset image Impish 21.10. I tried to run umpc-ubuntu script many times after install but it does nothing more. But I have to tell that when I'm using a stylus it's ok, the pointer is calibrated well, the issue is only when using the hand.

Do you have some ideas to help me fiix that please ? thanks for your help !

best regards

Thibault

1. Ditch 99-gpd-pocket3-touch.rules, looks like touchscreen works out of the box and rules are not applied in the live boot.
2. I have tears in Mate as well.

After a lot of searches I found this :

sudo gedit /etc/X11/xorg.conf.d/20-intel.conf

2) Add this:

Section "Module"

Load "dri3"

EndSection

Section "Device"

Identifier "Intel Graphics"

Driver "intel"

Option "DRI" "3"

EndSection

3) Save & Reboot

Tears are not there anymore but it's not usable, performance are awful, gpd pocket 3 is blowing and adding 2 monitors is not working too... I'm still stuck

I found a more easy way to get touchscreen correctly calibrated and working, without tears or performance issues by simply switching from X11 to Wayland on PopOs :

• set WaylandEnable=true in /etc/gdm3/custom.conf
• run systemctl restart gdm.service - note that this will log you out and close all open programs
• at the log in screen, there is a small gear wheel on the bottom right side, choose "Pop on Wayland" instead of "Pop"

If your screen orientation isn't ok, go to settings > screens > orientation and choose "Portrait on left"
