fbdev requirement of qemu

[PETER EASTHOPE]

Folk,

I've installed qemu, xserver-xorg-video-fbdev and libggi-target-fbdev
and tried to boot an image.

qemu -m 40 -boot d -cdrom /home/peter/Desk*/AosCD.iso

This error report ensues.
=======================| DirectFB 1.0.1 |=======================
(c) 2001-2007 The DirectFB Organization (directfb.org)

------------------------------------------------------------

(*) DirectFB/Core: Single Application Core. (2008-05-15 14:24)

========================================

qemu has no 'fbdev' option that I can see.
Is another package needed to make fbdev work?

Thanks for any ideas, ... Peter E.

Say me the resolution and colour depth of your screen and I say you
what to add after vga= to the kernel line of your /boot/grub/menu.lst.

Nice greetings

So you have to add the value beginning with "0x" that matches to your video
settings to the kernel line in the /boot/grub/menu.lst.

I'm using vga=0x368 since 8 bits are enough for the console and at 24
it's too slow. Maybe I should try nvidiafb? But I recall some problems
with the non-free module... Maybe someone else has tried this?

Andrei

Hello Richard Möhn and Andrei Popescu,

rm> ... since I cannot answer soon if you will not reply today ...

Sorry. I am not ignoring replies. Work
prevented attention before the weekend.

rm> ... installed hwinfo and that printed this list ...

Many thanks. Will try specifying video modes
when at work in Vancouver this week and try to
report success or failure by the next weekend.

ap> I'm using vga=0x368 ...

Logically, the reason for specifying a video
mode at startup is not obvious. Why can't qemu
and directfb proceed using a default video mode?

Thanks, ... Peter E.
