Ubuntu 19.10 (Eoan Ermine)

Nice, I've not heard of Prema BIOS mods until now. One thing I will say is I've not had any weird ACPI issues with my new Fusion IV. Everything works out of the box including the Nvidia GPU. It's the first laptop I've had in over a decade with Nvidia graphics where I haven't had to mess about with all this stuff.
Ubuntu 19.10 (kernel 5.3.0-40) runs fine on the 14" Fusion IV, with one exception: the touchpad
- It sometime (randomly) hangs
- When waking up from sleep, it causes an IRQ storm which causes the battery drains really quickly. If that is the case, you will see the following process consuming a lot of CPU in top:
[irq/130-UNIW000]
The reason is with the i2c_hid driver. So when it hangs, you can solve this by reloading the driver. To do so, open a terminal and typing
sudo modprobe -r i2c_hid
sudo modprobe i2c_hid
For the sleep issue, you can add these commands to the system-sleep hook:
/usr/lib/systemd/system-sleep/00_check_touchpad_status_systemd
My file looks like this:
#!/bin/sh
#copy to /etc/pm/sleep.d
LOGFILE="/var/log/sleep.log"
case $1/$2 in
pre/*)
echo "Going to $2..."
# Place your pre suspend commands here, or `exit 0` if no pre suspend action required
modprobe -r i2c_hid
;;
post/*)
echo "Waking up from $2..."
# Place your post suspend (resume) commands here, or `exit 0` if no post suspend action required
echo "Resume systemd from suspend at `date`" >> "$LOGFILE"
modprobe i2c_hid
/usr/bin/python3 /usr/share/touchpad-indicator/check_touchpad_status.py resume
echo "Touchpad enabled"

And firmware : They developped open firwmare on N141 and N151 with CoreBoot. They are more than just integratorsAfaik System76 are Clevo chassis - what they (claim they) do to add value re Linux is on the software side.

I'm probably going to be getting a new laptop in the new year.
Do you know if 5Ghz wifi is supported on the Intel AX200? Part of the reason I'm getting a new laptop is due to my current one only supporting 2.4Ghz wifi and the interference from other (2.4Ghz) access points in the neighbourhood is getting pretty bad.
yes it is, running stable connection with ax200 @700Mbits 5Ghz
