Normally, it's the last 1, 5 and 15 minutes in most distributions... ;-)

Indeed it does. ;-)

Well, no... There is nothing wrong with any processes. Everything runs
as it should, but the videocard sends a solid color to the monitor.
There is nothing on the screen anymore but this color, from corner to
corner. It just makes you blind at the wheel, so to speak. That's why
I then use my /Ctrl+F12/ shortcut to switch to my root console on the
12th virtual desktop, and then type...
.. blindly. I can manage that without too much of a chance for typos...

No, when I do that, then the screen usually just becomes another fully
solid color. Or else it might stay the same color - it varies,
It really *is* nothing but a hardware failure. Often, the videocard
will also mess up the rest of the system at boot time then by sending
back some incorrect voltage or whatever it does, causing the kernel to
suddenly see three out of seven logical CPU's - my system has four
logical CPU's... :-/

No, passing it on to the wastebin, probably... ;-)
