A[fter a reinstall of Debian] all looked very fine, and I decided to restart the computer. The first observation was that suddenly all the devices defined and mounted in /etc/fstab appeared as icons on the desktop, and I could not remove them. Next was that all of my settings of Caja file manager were gone. I use to make some personal adaptation: first I prefer one mouse click to open a file from the icon, the list view instead of icon view and a few other options like these. Until now all of these settings has been saved and restored at every login, but now they are lost and has to be redone every time. The same deals with the wi-fi password, I have to write it in at every login.
Next observation is that I can add no program starters to the panel. Well, yes, I can add one starter, but no more, they do not appear there. I can remove the first icon, and add another one, but still just one. Creating them, even more than one, on the desktop causes no problem.
If all these effects come from the same source I do not know, but I suspect they do. Some package might have unintentionally been removed, but if so I have not been able to find out which one. I have made reinstalls of al lot of them, e.g. mate-panel, but without any result.
Could anyone find the common factor, I would appreciate it. If nothing else I will of course make a new reinstall, but it takes a good deal of time, and I feel it ought to be unnecessary.
