According to Gouwa’s suggestion, creating a topic for my VIM1 related problems with Ubuntu (xfce-bionic_Linux-4.9_armEMMC_V2081030)
Bluetooth not working
unsuccesfully tried BT tethering and connection to the speakers.
connection to speaker sometimes succeeds, but sound is jerky, --> BT totally unusable
Screen rotating not possible
that’s a shame, because VIM would be a perfect digital signage device (portrait mode often needed)
RTC useless - saving time to it is impossible (of course the battery is connected)
Answer to hwclock -rD is either
“No usable clock interface found” or “hwclock: select() to /dev/rtc0 to wait for clock tick timed out”
Have noticed that fake-hwclock is installed and enabled.
That should be disabled, once the real RTC starts working…
