That was quite a surprise, my usual install procedure did not go smoothly as far as languages. When I did a fresh install, I selected the French language by mistake. I prefer to run my system in English, but meh, no problem, I can change it after.. Well, not so easily.
There was an option when I chose English from the Language Support menu to update all my folder names. Which I said OK to. The folder names were properly updated, except that the former “Bureau” remained, in addition to a new “Desktop” file, and some confusion between the two for the system, even after an overnight reboot.
The only way to get it straight was to choose English from the GDM menu, make it default, and choose a GNOME session.
I played around with symbolic links to no avail.
