I had an old installation of Debian 8 (Jessie) on my HDD, kept just as a fallback. I decided to archive it and free the disk space.
So I first made a Clonezilla backup, then I made a bootable full install copy on 32Gb USB drive.
Tested the USB drive with a boot, and it fails to run? Hangs in the gdm Display Manager screen with no mouse pointer.
So I mounted the USB drive from another Linux, and disabled gdm, suspecting that was at fault.
Then boot again, and I get a terminal login prompt, login and everything seems OK… until I try startx… then the same thing… brings up the Gnome screen with no mouse pointer.
Much head scratching and fiddling with /etc/fstab to make sure things are mounting properly. No progress… Then suddenly in one trial boot, a firefox window comes up with a message about dropbox requiring a new authentication or something, and still no mouse pointer…
Here at last is a clue. Mount the USB drive and disable the dropbox daemon. Boot again, and behold It all works, I even have a mouse pointer. Put gdm back , and that works too.
So I am happy with my archive now
can anyone explain why dropbox was perfectly happy in Debian 8 on my HDD, but the moment I moved Debian 8 to a USB drive on the same computer, dropbox complained about some rubbish and disabled my mouse pointer for good measure?
I dont see the link between dropboxd and the mouse pointer?
