Just like with invoking startx from the console shell, it starts the session just perfectly. Last night this ability to get a text console stopped working.

Once I login, I can use startx(1), to start a gnome session, xinit(1) will NOT work (lack of permission to write (false!).) This is very strange!. This happens in a very tiny font, so small my tired old eyes cannot read the screen. Indeed it does (goes to sleep), Most times, I can do a three-fingers salute 2 or 3 (Ctl-Alt-F2, Ctl-Alt-F2). Within seconds the Philips monitor announces it is going to sleep for lack of signal. The gdm3 worked for a say or so, then this I am running Gnome with several extensions.
