having the same issue i think.
solution is unclear to me.
the main partitions of my linux disk are not showing up in dolphin because they are of a org.freedesktop.UDisks2.Partition: Type: that is listed in
/usr/lib/udev/rules.d/80-udisks2.rules as
# ------------------------------------------------------------------------
# ------------------------------------------------------------------------
# ------------------------------------------------------------------------
# Devices which should not be display in the user interface
in the section
# special GUID-identified partition types (EFI System Partition, BIOS Boot partition, RAID/LVM)
# see http://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs
these are the offending references in that file
so what is the best path forward to clear them from this list?
