Hello!
I have developed an embedded application which uses SDL and linux/framebuffer.
I’d like to disable ctrl-alt-Fn console switching, because actually there are
no consoles at all in the underlying system. Is it possible?
Regards,
Ctirad

If there is nothing running on other ttys, it should be not possible to
switch to them. So, check out your /etc/inittab.
This has nothing to do with SDL.Am Monday, dem 21. Jan 2008 schrieb Ctirad Fertr:

inittab only controls whether something runs by default on any given virtual
terminal. it does not control whether the virtual terminal exists at all
(and thus whether you can switch to it). their existence is solely
controlled by the kernel.

There is no /etc/inittab. In fact there is no init at all. Kernel starts a
little script, which does some basic initialization (e.g. mounts /sys /proc
etc…) and then it starts my application. The only existing console is
redirected to /dev/null.
However, from the appliacation I can switch into black screen via any
combination of ctrl-alt-Fx except ctrl-alt-F1, which is appliaction itself.
Any ideas?

Technically, it is possible. At least X11 does this somehow:
Option “DontVTSwitch” "boolean"
This disallows the use of the Ctrl+Alt+Fn sequence (where Fn
refers to one of the numbered function keys). That sequence is
normally used to switch to another “virtual terminal” on
operating systems that have this feature. When this option is
enabled, that key sequence has no special meaning and is passed
to clients. Default: off.On Monday 21 January 2008 12:52:24 Ctirad Fertr wrote:

You can change SDL_fbevents.c at around line 1016 to disable VT switching.
There’s currently no API or environment variable way to do it.
See ya!

Thank you very much. That is exactly what I needed.
