    Blank Desktop

    When I login with Ubuntu (Default) I get a blank desktop. Ctrl+Alt+T is not working. I am able to get a terminal with Ctrl+Alt+F1, but the keybord is changed from "se" to I suppose "us".
    Login with Gnome Flashback (Compiz) and Guest Session works fine. The Guest Session uses Unity. I have also created a new user, that works fine with Unity.
    As I understand the only difference between the old user and the new user is /home/user. I have not succeeded to identify the file in /home/user, that creates the problem.

    I am using systemd, but .xsession-errors contains the following for the working user
    Code:
    openConnection: connect: No such file or directory
    cannot connect to brltty at :0
    Script for ibus started at run_im.
    Script for auto started at run_im.
    Script for default started at run_im.

    and this for the user with the blank screen

    Look at this thread. Is it the same problem?

    Unlike you I have not specifically installed systemd. I am letting things take their course. Today's updates brought in systemd stuff and my system reboots fine. I have systemd version 208-8ubuntu1. What version do you have?

    Apport interacts with DBus and so must SystemD and at-spi2-core is described as Assistive Technology Service Provider Interface (dbus core). I have version at-spi2-core 2.10.1. What version do you have? Try removing systemd from your boot parameters and using recovery mode to update and see what effect that has.

    My experience on my Lenovo ThinkCentre 58p Intel core 2 duo 3 gHz

    Utopic amd64 boots to desktop and cursor, no unity. Looks much like your experience.

    I've a pile of launchpad bugs on that, example https://bugs.launchpad.net/bugs/1359299

    Utopic i386 32 bit most always boots O.K. to unity, occasionally only desktop.

    From a couple other bugs, Compiz fails to start because of some interaction with X. No compiz, no unity. X is running fine.

    amd64 Utopic 3.16.0-6 and previous run fine.

    Utopic 3.16.0-7 and later compiz/unity fail mostly.

    There've been notes that a compiz change was made.

    I'm not aware that the Intel driver has changed. I don't know if utopic i386 and amd64 use the same Intel video driver and compiz. How do I tell?

    Use code:

    Code:
    lshw
    in terminal.

    3.16.0-10 amd64 iso boots to desktop no unity i.e. no compiz.

    3.16/0-10 i386 32 bit desktop, compiz, and unity running O.K. for a development release.

    +1 for amd64. Don't have a i386 install to test.

    This might be the same problem as reported by jerrylamos. There are however some differences.
    - I have created a new user that works fine with Unity
    - I am using Nvidia graphics with the proprietary driver

    The at-spi2-core version is listed as "2.10.2.is.2.10.1-0ubuntu1" in Synaptic.
    This is an amd64 installation upgraded from Ubuntu 13.10 to 14.04 to 14.10.

    I don't think it's a HW problem as Unity works fine in the new user.

    same results for me. started a few days ago....blank desktop, no unity, launcher, or dash, just wallpaper. was able to get to terminal with ctrl-alt-f1. then did a sudo reboot and ended up booting into gnome shell, which loaded without issue. like P-I H. i was also able to create a new user which booted up into unity without a problem. also have an nvidia card w/proprietary drivers.

    i finally fixed it by resetting compiz/unity with the following commands:

    Code:
    dconf reset -f /org/compiz/
     
    setsid unity

    Re: Blank Desktop

    dconf reset didn't work. The system complained about X11 not started.
    I used this command in a terminal to remove most configurations in the /home/user directory.
    Code:
    rm ~/.gconf ~/.gconfd ~/.metacity ~/.compiz-1 ~/.config/compiz-1 ~/.config/dconf -rf
    This was much easier compared to a new installation.
    I got a default launcher and theme. The panel included the same indicators as before.
    When I use the Dash to start an application, the configuration of the application is OK and I only need to lock the icon in the Launcher.
