|
|
I have been trying to get the Framebuffer to work. I have just recompiled the kernel, and im pretty sure i have all the options neccesary for it to work. I am using GRUB and in menu.lst i put vga=791 in it. I have tried this line right after the kernel, and also at the very end of the line...it still boots at 640x480 and i have no idea why! |

I can't remember the numbers off the top of my head, but youi need to use hex one.
Mine is:
This gives 1280x1024 framebuffer console.
Have a look in /usr/src/linux/documents/... for the framebuffer docs, there are two files, I think one is called fb.tx and the other is vesa.txt.
If you are using an NVidia card then make sure your kernel is only compiled with vesa framebuffer support, don't compile the nvidia framebuffer support. _________________ Troy

My kernel line in /boot/grub/menu.lst looks like this:
Code: | kernel /boot/bzImage-2.4.15-pre5 root=/dev/hda3 video=tdfx:800x600 |
Note the formatting...granted, I'm using a Voodoo3 and I have no exp with other setups.

Try vga = ask
It lets you specify the resolution every time you boot up, it's good for figuring out what modes work well with your video adapter/monitor. |

The why is because you are passing the wrong arguments to get what you want. Try reading through the docs in /usr/src/linux/Documentation/fb/yourvidcard.txt or /usr/src/linux/Documentation/fb/vesafb.txt if your card is not listed. There should be a chart in those documents with values you need to pass to the kernel to enable the resolution and bit depth you want.
Most Important, read relevent files above to find options you need to pass to kernel, and how to configure your kernel. Each fb driver is different.
Here is a very helpful howto:
http://www.tahallah.demon.co.uk/programming/Framebuffer-HOWTO-1.2.html
Please READ all this information before attempting to configure your setup, no need to do it more than once.

I have an NVidia card (GF1 DDR), can I ask why to use the vesafb driver? MPlayer docs say:
Quote: |
NOTE: FBdev video mode changing _does not work_ with the VESA framebuffer, and don't ask for it, since it's not an MPlayer limitation.
|
How can I play a movie file full-screen using MPlayer and framebuffer ?
Anyone who has experience with this? |

I don't know about mplayer, I've never used it, but I've used xine fullscreen without a problem, and I have an nvidia without framebuffer. (X) |

Runs fine in X here; I wanna use fb though, without X. |
