reason when I boot to a kernel that I have compiled the thing complains
that /dev/fb0 is not a valid device. I've compiled the kernel including with
Y for YES the options for framebuffers and console fb but it still doesn't
work. I even took the stock Debian 64bit 2.6.9 kernel and built it without a
make config. So everything is a module, but it still doesn't work.
I've found something interesting though. I downloaded a piece of software
called fbset which is supposed to allow you to switch fb settings on the fly.
I tried it out on my self-compiled kernel and it gave me this:
# fbset open /dev/fb0: No such device
When it works (on the default kernel) it looks like this: # fbset
mode "1024x768-76" # D: 78.653 MHz, H: 59.949 kHz, V: 75.694 Hz geometry 1024 768 1024 768 32 timings 12714 128 32 16 4 128 4 rgba 8/16,8/8,8/0,8/24 endmode
Now, I thought maybe the other default kernel has extra stuff on it so I booted to it and checked the loaded modules and I saw that it had these installed: vesafb 7480 0 cfbcopyarea 3968 1 vesafb cfbimgblt 3136 1 vesafb cfbfillrect 4224 1 vesafb fbcon 39648 0 font 8960 1 fbcon
So I booted back to my own kernel and loaded these modules (no problems loading) but I still, according to the system, don't have a /dev/fb0. I can do a 'ls /dev/fb*" and see fb0 through fb7 but it still says that they don't exist.
# ls -la /dev/fb* crw-rw---- 1 root video 29, 0 Feb 11 08:22 /dev/fb0 crw-rw---- 1 root video 29, 1 Feb 11 08:22 /dev/fb1 crw-rw---- 1 root video 29, 2 Feb 11 08:22 /dev/fb2 crw-rw---- 1 root video 29, 3 Feb 11 08:22 /dev/fb3 crw-rw---- 1 root video 29, 4 Feb 11 08:22 /dev/fb4 crw-rw---- 1 root video 29, 5 Feb 11 08:22 /dev/fb5 crw-rw---- 1 root video 29, 6 Feb 11 08:22 /dev/fb6 crw-rw---- 1 root video 29, 7 Feb 11 08:22 /dev/fb7
It seems like I need to do something with the kernel but I've tried almost everything in the kernel config options and have been unable to get framebuffers working. Does anyone know how to fix this issue?
BTW: I'm using an Nvidia FX5700 Ultra, though it shouldn't matter cause it works in the default kernel.
Thanks,
