• How to start gnome-shell?

  - by Tim

  I successfully installed GNOME 3 and GNOME Shell from the Launchpad PPA on my fully updated Natty test system. However, nothing I tried could get it to actually run. If I selected it in the startup options, I got a plain light blue screen with absolutely nothing on it. If I tried to start it using gnome-shell --replace, I got: gnome-shell --replace & [2] 3251 tim@nattytest:/usr/lib$ Traceback (most recent call last): File "/usr/bin/gnome-shell", line 705, in <module> normal_exit = run_shell() File "/usr/bin/gnome-shell", line 293, in run_shell if shell is None: UnboundLocalError: local variable 'shell' referenced before assignment /usr/bin/compiz (core) - Error: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager. [2]+ Exit 1 gnome-shell --replace I also tried preceding that with metacity --replace, as suggested at ubuntuforums.com. But, I got the same failure. I also linked /usr/lib/libmozjs.so to /usr/lib/xulrunner-2.0b12/libmozjs.so, which did not help either. No matter what I try, I get the same error messages.

• What would cause the "gi" module to be missing from python?

  - by Catalin Dumitru

  After some not so clever editing of the default Python version in Ubuntu, from 2.7 to 3.2, I ended up breaking my entire system. After my computer imploded and everything stopped working, I tried to revert back my changes (by linking /usr/bin/python2.7 to /usr/bin/python and changing the default version in /usr/share/python/debian_defaults back to 2.7) but some things are still broken. For example when I type "import gi" in the python interpreter I get the fallowing message : >>> import gi Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named gi >>> error which appears with some programs too (eg: gnome tweak tool). I have tried re-installing python both from the software center and from sources, but the same error persists. Python -- version now returns : Python 2.7.2 and also some software packages which depend on python 2.7 are now working (for example the software center), but some things are still broken. Is there anything I can do to completely re-install python 2.7 as the default version?

• Why do I have a gnomekeyring.IOError when doing "quickly share"?

• Unity calendar lens not showing events

  - by David_G

  I'm trying to get proper/useful calendar integration into Ubuntu 12.04. I have a Google Calendar (& account) and I want to be able to use this without opening the browser. I want to get the Unity Calendar lens working, so that it shows events coming up, and it allows me a quick way to add new events. However, after installing it, it does not find any events, nor allow me to add a new event. Note that I've installed Lightning 1.4, Evolution mirror 0.2.3, Evolution, and unity-calendar lens. I've also installed Calendar-indicator. I suspect that somehow the lens is not getting the calendar information from thunderbird via evolution. A bit of searching around led me to try this command: /usr/lib/calendar-lens/calendar-lens-daemon.py. With this result: /usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject Traceback (most recent call last): File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 324, in daemon = Daemon() File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 80, in init for calendar in evolution.ecal.list_calendars(): AttributeError: 'NoneType' object has no attribute 'list_calendars' Any ideas?

• Problems compiling with Quickly

  - by espectalll123

  Welcome to another of my questions about compiling! :P So, after days of stress trying to compile my app, first manually, after porting the project to Quickly, I decided to create the project from scratch using this time Quickly. Now I've finished the app, it works great using quickly run and I haven't added any new file, just removed, replaced or modified. But it can't be compiled using quickly package --verbose --extras... why, if there doesn't seems to be errors related with my project? The fail happens because python-mkdebian doesn't haves enough parameters to work.

  I have a laptop with dead battery that when there is no current connected to it turns critical so fast and in the energy management in ubuntu, when the battery is critical, there are 2 options: shutdown and hibernate witch is in grey (unclickable), so I have no choice but to chose immediate shutdown, there is no standby even if it is an option in the screen behavior.

• Restore Failure from Ubuntu One

  Had to do a reinstall of Ubuntu 12 after 13.10 failed. Lost all my data, but I remembered that I had data backed up to Ubuntu One. It recognized my previous backups but I got errors and a restore failure when I went to restore the data. This is what I got. Can anyone make heads or tails of this? I still don't have my data.

  I installed Dashboard following this guide: http://wiki.openstack.org/OpenStackDashboard Everything fine, but when I run the server, I can not login with the username and password in DATABASE config in local_settings.py. Here's my config: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'dashboarddb', 'USER': 'nova', 'PASSWORD': 'nova', 'HOST': 'localhost', 'default-character-set': 'utf8' }, } When I run the Dashboard server and enter username + password. It returned this error on browser: Unable to find the server at mykeystoneurl (HTTP 400) And in the command line: DEBUG:openstack_dashboard.settings:Running in debug mode without debug_toolbar.

However this server will be providing https access only to the repos, the http is only temporarily open. This might be due to the certificate not being valid on the https (since it's self signed) or due to the fact that vmbuilder doesn't support https? In either case how can i get this to work? (If it's the case of the invalid certificate I don't mind ignoring any checks)

• Unity calendar lens not showing events in Ubuntu 12.04

  - by David_G

  I'm trying to get proper/useful calendar integration into Ubuntu 12.04. I have a Google Calendar (& account) and I want to be able to use this without opening the browser. I want to get the Unity Calendar lens working, so that it shows events coming up, and it allows me a quick way to add new events. However, after installing it, it does not find any events, nor allow me to add a new event. Note that I've installed Lightning 1.4, Evolution mirror 0.2.3, Evolution, and unity-calendar lens. I've also installed Calendar-indicator. I suspect that somehow the lens is not getting the calendar information from thunderbird via evolution. A bit of searching around led me to try this command: /usr/lib/calendar-lens/calendar-lens-daemon.py. With this result: /usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject Traceback (most recent call last): File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 324, in daemon = Daemon() File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 80, in init for calendar in evolution.ecal.list_calendars(): AttributeError: 'NoneType' object has no attribute 'list_calendars' Any ideas?
