    Issues with Unity on 12.10

    Hello everyone,

    I took the time this past holidays to give a try at 12.10. I installed it in an available partition in a laptop. Everything went went fine the first couple of times I booted into it, but I'm now experiencing some odd behaviour.

    First of all, the Launcher isn't shown after the login, I have the Dash and the super key menu, but not the pretty icon list on the left. On occasion it appears back again (not clear what triggers it) but most of the time it simply doesn't show up through out the session.

    Another problem are the appearance settings. Every time I log in they seem to be automatically reset to the defaults; the wallpaper, for instance, has to be re-selected each time I log in.

    Any hints on possible causes of these behaviours would be much appreciated.

    Thank you.

    You can have the Launcher on the desktop all the time. Go to Dash, Applications, Appearance and look at the top of the page for Behaviour. Click on it and you can see there a way to have the Launcher on all the time by clicking the OFF sign on the right.

    Hi jgm, thanks for answering. I'm not referring to the auto-hide behaviour, the Launcher simply isn't shown, weather auto-hide is on or off.

    Do you get the top panel?

    There have been issues with Nvidia drivers where both the top panel and the Launcher did not appear. Another issue was where the Nvidia driver did not understand where the left edge of the screen ended and was putting the Launcher a few centimetres outside the left screen edge and hence out of sight.

    I experienced these issues during the development of 12.10 when the Nvidia drivers where updated.

    I use Nouveau drivers all the time. I got fed up with busted Nvidia drivers. Made my testing of 12.10 development branch unusable at one point.

    For the record. All the Ubuntu maintainers can do is pass the bug reports up to Nvidia and wait. They may be able to put in a work-around but that can be broken by a Nvidia update. Ubuntu developers cannot fix proprietary code.

    Regards.

    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    Yes, no problem with that.

    My graphics card is a Radeon HD 3650; I don't have any proprietary drivers installed.

    Where/how can I get these for my laptop?

    Thanks.

    You could try setting all the compiz settings back to default.
    In Quantal the terminal command is...
    Code:
    dconf reset -f /org/compiz/
    Then logout/in.

    Hi stinkeye, that didn't do it, but apt-get upgrade apparently did (only logged in once after that). Thanks in any case.

    I still have the issue with the wallpaper, though.

    The Launcher is gone again today. This is driving me nuts.

    Make sure you have the latest updates...
    Code:
    sudo apt-get update && sudo apt-get upgrade

    What gfx drivers are you using?
    Code:
    lspci -nnk | grep -iA2 vga
    eg
    glen@Quantal:~$ lspci -nnk | grep -iA2 vga
    01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF116 [GeForce GTX 550 Ti] [10de:1244] (rev a1)
    Subsystem: Giga-byte Technology Device [1458:351a]
    Kernel driver in use: nouveau
    P.S. Next time the launcher disappears, if ctr+alt+t works to open the terminal, reload unity to see if the launcher appears.
    Code:
    setsid unity
