Re: [directfb-users] directfb error

Gang,

I found out what the problem was. After searching for two days and recieving help from a few people (thanks Lecca and Attilio), I figured out the problem. I ended up copying over the kernel from the working computer to the one that didn't work (to rule out a module not being loaded correctly or something like that). The computer still ended up booting up with no luck. However (even before copying over the other computers kernel), I would get the error

You passed an undefined mode number,
Press <RETURN> to see video modes available , <SPACE> to continue or
wait 30 seconds.

After doing some searching in google groups for this, I realized Dell's have a problem with directfb and the onboard video card. I changed the video card with another one I had, and bingo! First reboot, it worked like a charm. The fbcon module loaded and everything. To see the post that pointed me to this conclusion, visit:

and see the last message in that post. Thanks again to everyone that tried to help me. I really appreciate your help. Hopefully this post will help anyone looking for a resolution to the same or simliar problem.

Thanks,
Dave

I use grub and have tried the following kernel lines:

kernel         /boot/vmlinuz-2.6.8-2-386 root=/dev/hda1 ro vga=786 append="video=vesa:ywrap,mtrr"

kernel          /boot/vmlinuz-2.6.8-2-386 root=/dev/hda1 ro vga=788 video=vesafb:ywrap,mtrr

kernel          /boot/vmlinuz-2.6.8-2-386 root=/dev/hda1 ro vga=788 video=vesa:ywrap,mtrr

none of them seem to work. On the machine that does work, I have the top line used. I think it might have something to do with the fbcon module not loading, but I can't get it to load.

If you use lilo set

append="video=vesa:ywrap,mtrr"
vga=791                                                /* or any that you want */

if you use grub, use this:

in kernel line: kernel /boot/ ..... video=vesafb:ywrap,mtrr vga=788

Reboot then try cat /dev/fb0

Cheers,

Luis

This is what I get when I cat the device file:

# cat /dev/fb0
cat: /dev/fb0: No such device

I already know this. I am not sure what to do to get it working. Any suggestions?

If you do cat /dev/fb0 you sould see -U-U-U-U-U-U-U-U on your screen when frame buffer device is installed...

IHIH, Cheers,

Luis

Gang,

    I have installed Debian on another computer with a DVD RW drive. I can mount the drive, read the dvd contents, but I can't play the DVD movie. I then tried to play a movie already converted into an AVI, but couldn't play that one either. I figured it might be a problem with X, so I decided to try to use directfb (since this seems to work very well on another computer I am using). I installed the libdirectfb, libdirectfb-bin, libdirectfb-extras packages for Debian, changed the grub boot loader configuration to reflect what is said in the "Configuring the linux framebuffer device" in the readme (as directed by Ville - thanks Ville), but to no avil, still no picture or sound. When I run with directfb, I get the following:

(*) Single Application Core. (with MMX support) (2005-01-31 07:23)
(*) DirectFB/misc/memcpy: using MMXEXT optimized memcpy()
(!) DirectFB/core/fbdev: Error opening `/dev/fb0'!
    --> No such device
(!) DirectFB/Core: Could not initialize 'system' core!
    --> Not supported!
(!) DirectFB/Core: Error during initialization (Not supported!)
vo_directfb2.c <274>:
        (#) DirectFBError [DirectFBCreate (&dfb)]: Not supported!

What am I missing. I have checked that the /dev/fb0 file does indeed exist with permissions 660, but I am still having problems. Any help would be greatly appreciated.

Thanks,
Dave
