Thanks for sharing all the requested logs.
I've got one idea to test out. It looks like there was an input fix for
systemd with v260 for your Goodix device. Obviously it would be a little
bit dangerous to move from v255 to v260. However we can have verify
whether you are hitting the same issue.
1. Open a terminal.
2. Check whether the released device rule is already installed. Copy and paste
this read-only command into the terminal:
grep -R -n -A2 -B2 'b0018v27C6p01E9' /usr/lib/udev/hwdb.d
/etc/udev/hwdb.d 2>/dev/null
3. Please paste whatever the command prints. If it returns to the prompt
without printing anything, let me know. That is still useful because it
suggests the matching rule is not installed in either location.
4. Next, copy and paste this command into the terminal (you may need to install
evtest first via apt):
sudo evtest
5. The command will show a numbered list of input devices. Choose the entry
containing Goodix or the matching device ID.
6. Before testing the touchpad, copy the device information shown by evtest. If
it contains ABS_PRESSURE, please include its minimum and maximum values. A 0 to
0 range would support this lead, while a nonzero range such as 0 to 255 would
help rule it out.
7. Move a finger on the touchpad for a few seconds, note whether any events
appear, and press Ctrl+C to exit.
8. Please share the log out of evtest.
