    When I boot I have full brightness, and if I set brightness to 7 I can see the light to go a little down, and I cannot get back to 100% without booting.

    Any clue?
    I find on windows 7 that the backlight up button is unreliable - the onscreen bars appear but nothing happens; i can reduce backlight but not always raise it again, and I have to use the fujitsu utility to set it to max and then I can reduce it to desired level

    OK, it's posibly entirely unrelated, but it could show that the hardware has some feature that causes backlight control to break?

    On ubuntu 10.04 I get no backlight control at all.

    I see that stskeeps aka carsten munk has solved a similar problem for the joggler

    "A patch for the IEGD kernel part to make it build and work in 2.6.33.2"

    about brightness: i'm using xfce and the brightness control appears as the volume bar does in top right corner. deleting or not the grub entry makes no difference: the delay remains.
    what i can't explain is that before installing gma500 driver (and so on) i had no probs with brightness but i couldn't make the volume hotkeys work.

    about jupiter: tried it in karmic. it works, unfortunately i was not able to use underclock or overclock (well, not even with lucid).

    Just installed with the instructions from here. Attempting to log in on UNR on my 1101HA just results in the Netbook Launcher sitting there grey for a while, crashing out and restarting in an endless cycle. I'm assuming this is a result of the lack of 3D support?

    Unfortunately, whilst the launcher works fine in 2D mode, that mode on UNR seems to be completely messed up with this bug affecting the panels, so I take it I'm stuck in standard GNOME shell until either that gets fixed or the driver 3D support gets improved?

    other thing: audio from speakers does not work, it does over earphones indeed.

    I have working audio on the 1101ha, but I added the backport-linux-modules-*, as alsa would sometimes crash before.

    I'd recommend installing also the backport-*-wireless modules, as the wifi signal seems stronger and more stable with them.

    After removing all old packages and installing from ppa my system popped for disk check and I ve got the message mountall: Plymouth command failed with the screen flashing and then blank. After that I cannot boot. Does it have to do with the bugs reported about plymouth and mountall or it is psb driver problem.
