[PATCH] fbcon->vgacon->fbcon

[James S. <jsi...@su...>]

Hi!

 Here is a new version of my vga patch. I now have it where you go from
vgacon to fbcon to vgacon again. I have tried this with the vga16fb
driver and it works very well. It needs a little work for a better
vgacon restore mode. Vgacon can even restore the fonts itself :-) 
I tested it with the matrox framebufer with less luck. I assume I'm not
freeing resources properly. I will test it with other fbdev drivers next
week. Thank you.

Matroxfb does not switch hardware to VGA mode on exit. Try doing
'fbset -depth 0 -a' before quitting from matroxfb.

I know. I wanted for vgacon to reset the video mode itself. This way ANY
fbdev driver can go back top vgacon.

That won't be possible because returning to VGA text mode is chip-specific.

when I'm talking to journalists I just say "programmer" or something like that.

From what I see in the XF4.0 tree you can. I will find out today with me
working on the tdfx driver.
