    Console broken on laptop [solution]

    I found a fix for the infamous console broken bug on laptop (blank screen or flashing cursor on tty1-6) on the ubuntu forum. Since I haven't found it here I thought I could share it. If it's already posted somewhere well nevermind...

    Tested on Acer 5920g (Core 2 duo, 2 Gb DDR2, 8600M GT) running Gutsy Beta with nvidia proprietary drivers.

    Symptoms: (added vga=791 in defoptions and run update-grub both with sudo) blank screen on all consoles or a flashing cursor.

    Solution:

    Code:
    1. edit as root:
/etc/initramfs-tools/modules

2. add 'fbcon' and 'vesafb'

3. your /etc/initramfs-tools/modules should look like:

fbcon
vesafb

2. sudo update-initramfs -u

3. sudo vi /etc/modprobe.d/blacklist-framebuffer

change the line "blacklist vesafb" to "# blacklist vesafb"
    It worked like a charm on my laptop. Hope it helps you guys.

    Sorry guys, this doesn't work anymore on kubuntu 7.10 final release at least on my computer. So I have no console at the moment.

      Works now!

      - Added 'vga16fb' to /etc/initramfs-tools/modules so it looks like:

      Code:
      fbcon
vesafb
vga16fb
      - Update with:

      Code:
      sudo update-initramfs -u
      - Put a comment mark on vga16fb (along with 'vesafb') so it looks like:

      Code:
      #blacklist vesafb
#blacklist vga16fb
      Works perfectly with vga=791 on my laptop (don't forget to do 'sudo update-grub' if not done already).

      The only thing is usplash was misplaced because the content of /etc/usplash.conf was:

      Code:
      xres=1280
yres=1024
      Which is a resolution I cannot use on my laptop. So I changed it to:

      Code:
      xres=1024
yres=768
      To match the resolution used by the framebuffer with vga=791 (which is 1024x768x16 bits) but it didn't work, usplash logo is still misplaced.

      Anyway, tty1-6 do work now ;-)

        The proposed solution works on my Dell Latitude C610.

        I had to update the "initramfs" after making all changes, not in between.

        Thanks a lot.

          Laptop: DELL5150
          Graphic card: NVidia FX5200
          Videodriver: nvidia (prop.)
          Distro: Kubuntu 7.10

          In addition to your recipe I added to /etc/modules
          these 2 entries before the other entries:
          fbcon
          vesafb

          After logging in without X the video-mode is 1024x768 (vga=791) now.
          Thanks!!
