Even though this title suggest it’s for peakago linux, it’s main focus is about how to configure the iio sensor for the correct screen rotation.
Gathering Information:First thing we need to do is gather the information we need to create a string similar to this
sensor:modalias:acpi:[driver name]*:dmi:*:svn[Manufacturer]*:pn[Product Name]:*to find the driver name we need to issue this command
udevadm info -n /dev/iio:device0in our case: BOSC0200 now we will need to find the manufacturer
dmidecode | grep Manufacturerand lastly the product
dmidecode | grep Productwith all that information gathered we can now put things together.
Lets put things together:
we first need to create a file called “61-sensor-local.hwdb” this way we wont accidently edit the 60-sensor file.
sudo nano /lib/udev/hwdb.d/61-sensor-local.hwdb
and in that file we create the string we need
followed by a new line of the correct rotation matrix
now we can issue this command to update the hwdb
sudo udevadm hwdb --update
once everything is in place, we can now reboot.

Firefox touchscreen scrolling fix
For touch scrolling to work with firefox there is a setting we will need to enable “MOZ_USE_XINPUT2=1”. now there are two ways to enable this feature. one is to start the program in termal with
env MOX_USE_XINPUT2=1 firefox
and the second which i recommend is to make it system wide on boot.
add this line
lastly if you want to have two finger scroll instead of one you can change this option inside firefox in the about:config
and edit this
default is 2
