Hardware status
Bluetooth
I was able to pair my Headphone and it works. Sometimes no device is listed in GNOME settings and I have to do `bluetoothctl` and then `scan on` for the devices to be shown. To make my keyboard and mouse work I had to do `apk add hidapi` and then `modprobe uhid` (if you have added the device before modprobe, remove and re-pair the device).
HDMI/DP
If I connect an external monitor, it breaks the Desktop showing only a blinking cursor on both device display and external display. If I plug in the monitor before boot, postmarketos boot animation is shown and then a (blinking) cursor on all displays.
I have been able to connect external monitors both directly in the case of a monitor with a USB-C input and via a USB-C with an HDMI output. However, the process to connect is temperamental and involves plugging in the USB-C device and then putting the tablet to sleep and waking it. I've had the same experience with a couple of different monitors so not sure what is causing it.
