The other case might be a mainsteam GPU (radeon, nouveau, intel) and
KMS support built in (or available as module) but disabled by "nomodeset"
cmdline option that did show up in a previous post.
Just booting with "vga=0x31a" (or another value more appropriate for
attached screen -- see Documentation/fb/vesafb.txt for list) might
provide a basic framebuffer device.
lspci for the affected system will certainly help at least indicating
which driver would be the right one.

Check if some frame buffer drivers are installed
in your system, so e.g. run
ls /lib/modules/`uname -r`/kernel/drivers/video
to see if there are any frame buffer driver modules
installed.
Then you have to select the suitable driver for your
graphic card and load it by running
modprobe drivername

Usually the driver should be loaded automatically if
it is installed. Maybe some error happened while loading
the driver. Dump the kernel log messages by running dmesg
and check if there was an attempt to load the driver for
your graphic card.

OK so how do I get a frame buffer driver loaded?
I don't have any backlisted framebuffer drivers, what is stopping me from
loading a frame buffer driver?
Does anyone know what I have to do?

Yes, this is expected since there is no frame buffer
driver loaded in your system.

I'll try to explain my understanding of the issue.
The device node file /dev/fb0 is only an interface to the frame
buffer driver. It can be created by the kernel automatically if
there is a graphic chip in the system and the appropriate frame
buffer driver is loaded and some device filesystem is initialized
and mounted, e.g. devtmpfs device filesystem.
Or /dev/fb0 can be created by the user, but if it has been created
by the user and there is no frame buffer driver running, then the
driver interface cannot be opened since no corresponding driver
responds when an application tries to open the device. This is
the error message that you currently see.
When you create the device node file under /dev at runtime, it will
disappear when rebooting, since the device file system under /dev
will be unmounted. Even if there is a /dev directory on your hard
disk with some existing device nodes, e.g. fb0 existing, there
is still a possibility that you won't see these nodes at runtime.
If the kernel creates device system at runtime and it is mounted
under /dev, the content of this device system will be populated
with device nodes for registered devices. When there is no frame
buffer driver loaded, no fb0 device will be registered, no device
node will be created.
Hope this helps,
Anatolij

The frame buffer driver for your graphic card is not in the
kernel or could not bee initialized properly, so this is one
reason for missing /dev/fb0.
Are kernel modules installed in your system? What is the output
of the command below?
ls -l /lib/modules/`uname -r`/kernel/drivers/video
If you do not know which graphic chip is in your system,
you might want to run
lspci -v | grep VGA
Then you have to install the appropriate frame buffer driver
kernel module or alternatively to build the kernel with frame
buffer driver included.

Hence your kernel is not using a frame buffer device.
Do you have a frame buffer device driver for your hardware in the kernel?

Hello Anatolij,
And when I reboot /dev/fb0 disappears again.
What is very strange to me is that when I run links2 -g the error message
says that /dev/fb0 does not exist, while if I list the file it says that
it is there ls /dev/fb0 says the file is there.
Strange to me.

Shouldn't you first set the voltage level for this regulator before
enabling this?

You have to add write permissions for the group also. Check if
/dev/fb0 can be accessed if you create it by using
sudo mknod /dev/fb0 c 29 0 -m 660
sudo chown :video /dev/fb0

What is the output of following commands on your system?
cat /proc/fb
cat /proc/cmdline
dmesg | grep vesa

Hello Florian,
What I'm trying to do is make a command line distribution with speakup so
that blind people and people who just like the command line can use it. I
still have some sight so occasionally I like to see the pictures that
links2 -g can display.
I have everything working in this system: alpine, mutt, elmo for mail,
emacspeak the complete audio desktop is loaded and running and speaking.
elinks, links2, w3m, and searchraw are all installed. All the console
multimedia stuff is in here, ftp, pdftotext converters, etc.
But the only thing that doesn't work on this is command links2 -g.
So I want this to be card independant - and my previous versions of Debian
command line Vinux (that's the distro) worked fine.
I have no /etc/modprobe.d/fbdev-blacklist.conf file at all.
I also have no /dev/fb0 file.
Here is my /etc/modprobe.d/blacklist.conf file - it doesn't have any fb
blacklisted either.
# This file lists modules which will not be loaded as the result of
# alias expansion, with the purpose of preventing the hotplug subsystem
# to load them. It does not affect autoloading of modules by the kernel.
# This file is provided by the udev package.
# evbug is a debug tool and should be loaded explicitly
blacklist evbug
# these drivers are very simple, the HID drivers are usually preferred
blacklist usbmouse
blacklist usbkbd
# replaced by e100
blacklist eepro100
# replaced by tulip
blacklist de4x5
# replaced by tmscsim
blacklist am53c974
# these watchdog drivers break some systems
blacklist iTCO_wdt
Any suggestions?
I have changed grub to give me a large 640x480 screen and that works but
and it gives me color say if I have bash add color to folders and
executables - and mc comes up in color but no links2 -g in color because
no /dev/fb0.
Any other suggestions?
I made my username member of its own group and also tty and video.
As I said before I tried mknod and that worked but when I rebooted
/dev/fb0 was gone.
I tried the mknod command again and it created /dev/fb0
which is owned by root and in root group. I changed the group to video.
Now root has rwx permissions the group can read and everyone can read.
I run links2 -g and it still says it cannot access /dev/fb0.
If I reboot /dev/fb0 will disappear.
I'm stuck!

what graphic card/chip do you have?
You might have to remove the corresponding framebuffer from

Shouldn't be necessary. If the correct driver is loaded the device should appear
immediately.

I want to make framebuffer work in console only Debian installation.
I find many of the howto's on the web won't work for current Debian
Stable - or I'm just too stupid to figure them out.
< grin >
I want to get fbi and links2 -g working in console.
I tried entering in console:
sudo mknod /dev/fb0 c 29 0
But when I reboot /dev/fb0 does not exist.
I've had links2 -g working before - I've got libdirectfb-dev
libdirectfb-bin and all the files I can find with directfb to install.
I am working on Debian Stable command line only.

Hmmm... you have a valid point, but I'm not keen on the idea of having two
memory blocks. I was even hoping to put mfb_info objects in fsl_diu_info,
but framebuffer_alloc() won't let me.

I can split it out. It will give me the chance to add even more
documentation.

What's going on? I could carry the patch but I'd want an Ack to do so.

In general this looks good to me. Just keep in mind that multiple small patches
are preferred.

The idea to merge multiple DMA objects sounds good. But I think you might want
to have a look at what you put in the DMA area. I think it would be better and
cleaner to put things that should be never accessed by the device, like
fsl_diu_info, irq, reg_lock and so on, in a separate structure.
> Documentation for some affected data structures and variables is added.
You could do this in an separate patch as it's independent of your idea to merge
the DMA objects. Well, I do not care very much in this case.

Okay.
