Just upgraded Xubuntu 12.04 to 12.10 (both XFCE and LXDE desktops are being used at this system). Now I have 2 mount points for each partition. It looks like this: It appears this way in both Thunar and PCManFM. However, there are no dupes in Nautilus. $ ls /dev/disk/by-id/ ata-ST320410A_5FB3MA76 ata-ST3250620A_9RT030B0-part3 scsi-SATA_ST320410A_5FB3MA76-part1 scsi-SATA_ST3250620A_9RT030B0-part4 ata-ST320410A_5FB3MA76-part1 ata-ST3250620A_9RT030B0-part4 scsi-SATA_ST320410A_5FB3MA76-part2 scsi-SATA_ST3250620A_9RT030B0-part5 ata-ST320410A_5FB3MA76-part2 ata-ST3250620A_9RT030B0-part5 scsi-SATA_ST320410A_5FB3MA76-part3 scsi-SATA_ST3250620A_9RT030B0-part6 ata-ST320410A_5FB3MA76-part3 ata-ST3250620A_9RT030B0-part6 scsi-SATA_ST3250620A_9RT030B0 scsi-SATA_ST3250620A_9RT030B0-part7 ata-ST3250620A_9RT030B0 ata-ST3250620A_9RT030B0-part7 scsi-SATA_ST3250620A_9RT030B0-part1 scsi-SATA_ST3250620A_9RT030B0-part8 ata-ST3250620A_9RT030B0-part1 ata-ST3250620A_9RT030B0-part8 scsi-SATA_ST3250620A_9RT030B0-part2 ata-ST3250620A_9RT030B0-part2 scsi-SATA_ST320410A_5FB3MA76 scsi-SATA_ST3250620A_9RT030B0-part3 $ ls /dev/disk/by-uuid/ 01CD9E239FDF54F0 5299-430B 8824C9E324C9D3FA b05c582e-77df-4b83-8a75-17db1ab5dbc1 09a9cf9e-6af4-45ed-a9ac-782c764fe8d1 6bbd501e-7601-4ee7-b725-d3ec7f19f149 8B7C-BAF8 f54ee301-4bd4-40e3-a9fb-75ca79c05974 50366CC66E8BA293 8553dc4a-5d63-4078-9be3-ea91a46d8c67 a5be1bcd-b7c6-4273-8ade-eb9cce15504d There are no SCSI drives in this system. What could cause this problem? Is it a bug?
