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

[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.

Are you using a ruby kernel? For the standard 2.4.0-testX kernels you
have:

AT keyboards:

pc_keyb.c -(raw)-> keyboard.c -(raw)-> pc_keyb.c -->
>--(cooked)-> keyboard.c -(chars)-> tty

USB using keybdev:

usb.c -(usb)-> hid.c -(events)-> input.c -(events)-> keybdev.c -->
>--(raw)-> keyboard.c -(raw)-> pc_keyb.c -(cooked)-> keyboard.c -->
>--(chars)-> tty

--------------------------------------------------------------------
For Ruby we do:

AT keybaords:

i8042.c -(raw)-> atkbd.c -(events)-> input.c -->
>--(events)-> keyboard.c -(chars)-> tty

USB keyboards:

usb.c -(usb)-> hid.c -(events)-> input.c -->
>--(events)-> keyboard.c -(chars)-> tty
-----------------------------------------------------------------------

For ruby you don't need keybdev.c. Also USB works great under ruby. Note
for ruby a vidoe terminal is defined as a video output and a keyboard. If
you have 2 keyboards and one monitor it sees it as a single VT. In the
future we will have a userland daemon that will allow wierd combos that
people want.

[Justin C. <jp...@do...>]

I know the documentation dezcribes keybdev as a hack, but I didnt realise
justt how bad it was: I just got a USB keyboard (designed for Mac) and
plugged it in and it works fine, but when I modprobe keybdev it remaps
the keycodes on my other keyboard, making it unuable. Removing the module

Good thing I really only bought it for use with events.

Anyone know why the power buttons on Mac keyboards arent mapped at all

I'll soon be adding serial mouse autodetection to inputattach so that in

For serial everything input. But onlt for serial, yes. It's because the
serial port is a TTY and thus needs an userspace program to change the

I compiled in serial port line displine and serial mouse. I do see the
needed object files in drivers/input. It also doesn't show up at boot time
where as the other mice do.

Both.

I use the Alternative driver (uhci.o). It works for keyboard and mouse. I
might not work for the joysticks. Also I have mistakenly been compiling in
usbmouse.c and usbkeyboard.c. I will give a try without. I might be
selecting the wrong USB controller.

USB or Gameport version? For USB you need

hid.c
[u|o]hci-hcd.o
joydev.o

for gameport you need

ns558.o
grip.o
joydev.o

I tried it with a microsoft serial mouse. It was the only on that didn't
work. I tried a few other serial mice thinking it might be that mouse but
it wasn't. Have you tried any serial mice.

It doesn't even initalize the joysticks at all. They are compiled in and I
have a bunch hooked up. It doesn't appear at at boot time as if it wasn't
compiled in. Also I gave the joystick programs a try. Still nothing.

Synced with test9

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

Hi folks.

  Sorry I have been quite but I was busy moving. Now it is time to get
back to work. The current tree is now against test9. Now that I'm at SuSE
I have alot og hardware at my disposal. With the current CVS code I have
tested it with regualr keyboard, USB keyboard and with a USB mouse, PS/2
mouse and serial mouse. I couldn't get the serial mouse to work :-(
Strange that my serial mouse at home worked. The rest worked fine. Also I
didn't get a gravis exterminator joystick working either. Well something
to work on. 

   Now for the video stuff. BTW Jason I did see your patch posted and will
be taking a look at it soon. Thanks. I'm currently working on working on
the ability to go from vgacon to fbcon and back. This will allow the
ability to debug fbdev drivers very easily. Also one of the main features
missing that will allow the removal of consoel code from fbdev drivers is
the lack of moving from a fbdev driver to vgacon. Once this is done we can
test fbdev drivers on vgacon systems with easy.

[PATH] Boot logo for Linux 2.4.x

[Jason M. <jmc...@li...>]

This patch is for Linux-2.4.x

	This kernel patch will allow you to have a full-screen
boot logo in any FBcon supported video mode, except for
VGA text mode. After applying the patch, you simply need to
answer `Y' to `Custom boot logo' under the Framebuffer Support
options. Then, place your custom boot_logo.ppm into
linux/Documentation/boot_logo.ppm

	When you recompile your kernel, the boot_logo.ppm
file will be reconstructed into a 214 color, 16 color, and
2 color B&W include file in linux/drivers/video/boot_logo.h

	When you boot into the logo-enabled kernel, the
logo will be automatically centered on your framebuffer,
and you will have 2 lines of kernel/init status at the bottom
of your screen. Like the std. ``penguin'' logo, your custom
logo will be repeated horizontally for however many processors
your have on your system, or however many logos will fit - whichever
is smaller. 

	To remove the logo from the screen, simply switch away
from, them back to, the original boot-up VT.

	Comments, suggestions, patches, etc. are welcome.
