I couldn't reproduce the problem with this event and other Lightning events are working here, too. This seems not to be related to Lightning, but to https://forums.bitfire.at/topic/1727/nullpointerexception-attempt-to-invoke-virtual-method-void-java-util-calendar-settimezone-java-util-timezone-on-a-null-object-reference. If I only could reproduce it…
Please follow up there.
Those notifications should disappear as soon as the next successful sync is run, which should happen a short time after an I/O error. Can you confirm that these messages go away by themselves?
Maybe we can change them to minimum priority notifications like in DAVdroid…
Output from sudo libinput list-devices | grep Device ...
libinput error: event17 - Network Tablet: libinput bug: missing tablet capabilities: resolution.Ignoring this device.
I tried starting the driver and device in a different order, in case resolution isn't set until the device first connects, but the error remains.
Is there any additional info I can provide to help debug this?
I second this. The ability to hide an app’s icon is already found in apps such as Google’s keyboard. Getting rid of its icon would save precious screen real estate in my launcher.
