Workaround 1

Display Brightness

See latest blog post for 9.10

Original workarounds:

As reported on http://www.mail-archive.com/desktop-bugs@lists.ubuntu.com/msg236918.html the function keys that adjust display brightness are not working.

I found that the screen brightness is too low when booting without AC power. I can, however, adjust the brightness at the GRUB menu on boot using the function keys but I had to disable the auto brightness function in BIOS (hold F2 on boot) to allow this.

*Update* Better workarounds available, see comments!

  1. Has anybody found an App that adjusts the NC10’s display brightness within Ubuntu?

  2. 1. Right click on a blank part of one of your Gnome panels.
    2. Select the “Add to Panel” menu item.
    3. Select “Brightness Applet” from the list.
    4. Click the “Add” button.

    You should now have an icon you can click on to get a brightness slider.

    I’d be interested to hear if this works on the NC10 – I’m thinking of buying one to run Ubuntu.

    Thanks for the blog, by the way!

  3. yes it works! thank you

  4. I’ve been using the Brightness Applet for a while (on other laptops before this), but an alternative is to set it up to use some keys:
    1. sudo apt-get install xbacklight
    2. gconf-editor (if it isn’t installed, use apt-get install)
    3. Select apps->metacity-> global keybindings to assign some keys for increasing and decreasing brightness
    4. Now set those bindings to:
    xbacklight -inc 10
    and xbacklight -dec 10
    If you have ubuntu-tweak, you will still need to download xbacklight, but you can set up the keyboard shortcuts more easily from tweak.
    Works for me (using F11 and F12 keys), and I prefer it to the applet.

  5. I think it’s also worth mentioning the little hack to get full screen brightness at boot-up time (from the Italian guide you linked to elsewhere on this blog)

    1. Set the brightness control to user manual in bios

    2. Use the fn keys to set brightness to full in the grub startup screen

  6. imke – I think that workaround originated here ;o)

  7. Further comments should be made using the forum located at http://nc10ubuntu.forumcircle.com/
