Qingy&Fbdev problem

I trying to setup qingy using wiki, but qingy works only in text mode. I think that problem in fbdev:

[opt1k@opt1k]$ fbset
open /dev/fb0: No such file or directory

What wrong?

Re: Qingy&Fbdev problem

I think that means that no framebuffer kernel driver is being used. I think the simplest way to use vesafb is to specify 'vga=<something>' as a kernel parameter in your boot loader (usually /boot/grub/menu.lst). That <something> is a numerical code for a mode. The default /boot/grub/menu.lst which comes with the grub package has a list in the comments.

The other possibility is that you'd try to use a driver specific to your graphics card; for instance if you have an intel card, you could try to 'modprobe intelfb' as root to see if it createds /dev/fb0 for you.

Yes, I have intel video card, but

'modprobe intelfb

does not help, fb0 device still not present in /dev
I will try with grub.

Re: Qingy&Fbdev problem

hi, i had the same problem when i tried to start links in graphical mode (links -g) today ... completely forgot to add my user to the video group to be able to have access to the framebuffer-device in /dev/fb0

try

gpasswd -a $user video # $user should be your username :)

It's worth a try, but if OP would have the dev but without proper permissions, the error should have been more like "Permission denied".

At my system after upgrade there is now /dev/fb/0 instead /dev/fb0. Solution is symlink (or fbset do it for you).
