Right.

In my opinion, on a single-user system (99% of PCs today!), devices like /dev/input/mice and /dev/tty? should be readable by the user and /dev/fb? read/write by the user (as long as it's a local user). It doesn't make any sense to make those devices administrator-only.
(as a matter of fact, locally, I chmod them +rw by the init scripts in order to be able to run linuxfb applications as user)

It did made some sense in the old days because some students with telnet would do stuff like "echo "Teh Admin is BOFH" > /dev/tty0" and that would be printed on the admin's monitor while he was giving a presentation to the board and be very embarassed. But multiuser systems are more rare and their administrators have the knowledge to tune them.

Multi-user systems more rare? Not rare enough! My home system is multi-user - I've got a Phenom X3, and use my old pc as a terminal so both me and my wife can share the main system. I bet there are plenty of systems like that around.

Pretty easy even for a non-BOFH to do ...

Cheers,
Wol

That is still single user. By "multiuser" i wasn't referring to multiple user processes at the same time but rather a system that gives (mostly remote) access to untrusted users.

In other words, i believe that the user sitting on the desktop should be -by definition- priviledged to use the input/framebuffer devices.
