Pressing ctrl-c within a DirectFB application usually doesn't work. It might work using no-vt without the linux-input driver, but switching VTs would still be a bad idea. > Now I'm setting up a system with a Matrox G450 card in it.

I'm wondering why the behaviour differs depending on the graphics card, but using no-vt disables the keyboard driver. But you can use linux-input instead. If you got the keyboard working in DirectFB you can use Meta-Escape that sends a SIGINT to the process, but only with the single application core. In the multi application core the key combination switches from exclusive apps to the desktop. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
