Package: linux-image-4.19.0-1-amd64 Severity: important Device: Surface Go
Debian Version: Buster with latest updates Summary: In general it is working fine, but it seems that some stuff is missing because device ID is not known and then its loaded in a generic mode and not device specific. E.g. the assumed battery should be remove because it is a touchscreen and also the power control needs adjustement. Please let me know which outputs are needed to get the Elantech toucschreen recognized properly. First: The touchscreen is reporting a battery status in GNOME Settings -> Energy and also in general in the system. This can be seen here: pink@debian:/sys/devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-1/i2c-ELAN9038:00/0018:04F3:261A.0001/power_supply/hid-0018:04F3:261A.0001-battery$ ls capacity model_name
