All drivers under drivers/video/console. That would be: vgacon dummycon fbcon newport_con sticon promcon mdacon There are perhaps a few more drivers outside this directory, such as sisusbcon or something. <snip> > >You may want to leave out the blink attribute (0x80) from this part. > >Otherwise setterm -blink on|off will produce the opposite effect. > > But 0x80 might be interpreted in a different fashion for some othercon, > yielding for example superbold rather than blinking. That's right. But setting the blink attribute is done with an XOR (^). So 'setterm -blink' on will unset the blink attribute (0x80 ^ 0x80). > I'll have to try this, because usually, setterm operates on TTYs > rather than VCs. Yes, but if the tty driver type is a virtual console, then vt.c is still affected. Well the blink attribute is ignored by most drivers, if I'm not mistaken. So you generally won't see the effect :-). But with fbcon, the blink attribute is interpreted as "change background color from black to light gray".
