In the version of Ubuntu 7.10 and above - framebuffer is turned off by default. To enable it we will conduct described below.

As a text editor, I use the nano, but you can use any other editor.

1. Open the file /etc/modprobe.d/blacklist-framebuffer :

sudo nano /etc/modprobe.d/blacklist-framebuffer

comment out the line:

#blacklist vesafb

and save the file.

2. Open the file /etc/initramfs-tools/modules :

sudo nano /etc/initramfs-tools/modules

add the line:

fbcon
vesafb

and save the file.

3. Rebuild the initramfs image

sudo update-initramfs -u

4. Edit GRUB2

Edit the file /etc/default/grub

At the end of the line GRUB_CMDLINE_LINUX_DEFAULT add the parameter vga=0x31b. Where 0x31b - the code required resolution, which you can find in one of the two options listed below.

GRUB_CMDLINE_LINUX_DEFAULT="splash quiet"

I changed to

GRUB_CMDLINE_LINUX_DEFAULT="splash quiet vga=0x31b"

And if you want that framebuffer worked in recovery mode, then change

GRUB_CMDLINE_LINUX=""

on

GRUB_CMDLINE_LINUX="vga= 0x31b"

You have to GRUB_CMDLINE_LINUX="", in quotation marks may be other options. In such a case, simply append to the existing at the end.

5. Apply changes to Grub:

sudo update-grub

The table of codes permit:

The table of codes permit
640x480 800x600 1024x768 1280x1024
256 0x301 0x303 0x305 0x307
32 тыс 0x310 0x313 0x316 0x319
64 тыс 0x311 0x314 0x317 0x31a
16 млн 0x312 0x315 0x318 0x31b

If you need a different resolution, then use the programme hwinfo:

1. Install the programme hwinfo

sudo apt-get install hwinfo

2. Run it with a key --framebuffer

sudo hwinfo --framebuffer

in the list that appears, select the Mode for your permission to add it to the vga=..., as described above, in the fourth paragraph.

It remains to reboot the computer and you can run in the console the mplayer or links2 (a console browser).

Later I’ll write about that, and with what parameters need to run these programmes.

P.S. For ATI, all the same, but in paragraphs 1 and 2 use radeonfb instead of vesafb.
