[SOLVED]GNOME 3.14 user switch not working

Hi everybody, happy new year.
I noticed quite recently that user switching doesn't work on GNOME 3.14 anymore.
I'm using nVidia drivers (343.36 from repo), I don't know if it's the one thing responsible for this, as desktop experience with their driver is becoming quite buggy in recent years.
Does anyone experience the same problem?
(I know it's not a very widely used feature but I got used to share the same computer at home and sometimes it proved to be very useful...)
Thanks in advance.
[Edit] I'm not talking about closing session, but switching between users on the fly...
[Solution] Fixed with nVidia drivers 346.35
=> It's more complicated than that! In fact package nvidia-346.35-2 forced me to create the following file in order to be able to start X:
/etc/X11/xorg.conf.d/20-nvidia.conf
Section "Device"
Identifier "Nvidia Card"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection
...and it worked with this configuration.
Bug when nvidia-346.35-3 hit the repos, I deleted the config file as it was no more needed to start X, but user switching once more failed to work as intended.
I created this file once again, restarted gdm (and thus X was restarted too), and everything went fine.
I don't know why a minimal config file is needed for user switching when it's not needed for starting X, though... GNOME devs might want to dig this.

Omer666,
This also fixed the problem I was having. The specific steps to reproduce the problem were as follows:
1. Log in as user1. (start some apps)
2. Click Switch User
3. Log in as user2.
4. Log out
5. Log back in as user1.
At this point without the above mentioned fix. user1's session will be restarted (or maybe it was killed when we clicked Switch User).
I'm running the nvidia drivers version 346.35-6.

  • [Solved] Gnome extension "Hide Top Bar" not working.

    I copied the directory found in the zip file I got from the github into /usr/share/gnome-shell/extensions and ran gnome-shell-extensions-prefs. The extension shows in the menu, but when I select it I get the error message:
    Error: Schema org.gnome.shell.extensions.hidetopbar could not be found for extension [email protected]. Please check your installation.
    Stack trace:

    I checked two things at this point. First, that "org.gnome.shell.extensions.hidetopbar" is indeed present (which it is), and second that my version of Gnome is supported. I have Gnome 3.12, and according to "metadata.json" 3.12 is supported.
    [edit] Like an blind idiot I failed to see that README file which says:
    Installation:
    Compile the gsettings schema by running
    mkdir ./schemas/
    glib-compile-schemas --strict --targetdir=./schemas/ .
    Install this in your extensions directory:
    ~/.local/share/gnome-shell/extensions/
    Example:
    cd ~/.local/share/gnome-shell/extensions/
    git clone https://github.com/mlutfy/hidetopbar.git [email protected]
    cd [email protected]
    mkdir ./schemas/
    glib-compile-schemas --strict --targetdir=./schemas/ .
    gnome-shell-extension-tool -e [email protected]
    However when I followed the istructions I end up with the error
    $ glib-compile-schemas --strict --targetdir=./schemas/
    You should give exactly one directory name
    [edit2] I failed to notice the "." at the end of the "glib-..." line.
    ITs working now. Sorry for wasting Forum space.

  • [Solved]Gnome 3 global proxy settings not working

    Hi
    My laptop runs Arch and I use it at a hostel and University. Both have different proxy settings and I had configured it by using a script (if one can call it that) in {/etc/profile.d/} that exported the correct settings. I had to edit (comment/uncomment) my setting every time I mover my laptop.
    I need the setting globally for Chromium to pick it up. Chromium until recently had a problem when accessing the Gnome 3 network (proxy) settings. A new update seem to have fixed this but the problem of picking up the setting remains.
    I started up a terminal to see how that global proxy setting in Gnome 3 were shown and found that only the following were set
    https_proxy
    all_proxy
    ftp_proxy
    The main one that I need {http_proxy} was not set, even thought I defined it. I think this is an issue with Gnome 3 and was not sure where I should report it. Any solutions will be much appreciated.

    I've had issues lately with Gnome 3 and proxy settings. For example, as of today (or sometime this weekend) Firefox is not obeying the system proxy settings (System Settings -> Network -> Proxy). Even better was that today I found that the system proxy settings had "magically" reset to proxy.company.com:8080 (or whatever their default setting is). If I manually set Firefox's proxy settings, it connects just fine. All terminal applications that I use only obey the http_proxy environment variable. Other programs, such as Evolution, seem to not obey the Gnome system proxy settings but only the ones set in GConf (not DConf) (which were also "magically" reset today).

    i have problem with my iphone 5 lock switch..as lock switch not working properly..and my iphone is not in warrenty.. so plz tell me what i do...

    The iPhone 5 is less than a year old, so all of them should still be in warranty unless they have been jailbroken or physically damaged. If you have a hardware problem as you describe the only option is to get the phone replaced by Apple or repaired by a non-authorized shop. The Apple replacement will be free at any Apple store in the country where the phone was purchased. If Apple determines that the phone was physically damaged or jailbroken it will cost $229.

    OK, so are you asking what do to, or are you just sharing your situation?
    If you're asking what to do, then you should bring your phone to Apple while it's still under warranty.

    Hi Ronny.
    Where is your UME running? On the java engine, on an ABAP system or at a LDAP?
    What i want to say is that your user has to gain the rights to connect to the SLD. Easiest way is to give you admin rights - to do that you have to know where your userstore is running....
    I am not sure if this is correct http://localhost:50000/sld
    Normally it should look like http://my.sap.com/56600/sld where my.sap.com is a fqdn and 56600 is the port of the java engine. 66 ist the system number of the as java.
    ZBAPI? I do not really know but i think you have to use a jco to connect...
    regards,

  • Three Way Switch not working

    Hi, i just bought a 4th-gen shuffle, and I've been using it with satisfaction since Saturday.

  • Nano 4th gen hold switch not working

    The seller claims the hold switch did work before he sent it. Is there anything I can try to get it to work? It's out of warranty.

  • User index not working as expected..

    Hi all,
    we have a ldap to which two instances running on two diff boxes are connected, there are approx 4000 users and all these users show up in instance one but for some strange reasons only 1000 odd users show up in instance two, ldap has been configured accordingly for maxhits....the ume index on the instance two was deleted and recreated but has not solved the prob...instance one is ep6 and instance two is ep7.0 ? can anyone who knows what might have gone wrong throw some light on this please ?
    thanks in advance,
    Anupama.

    Thanks for the reply Scott, I have just had one of those Homer Simpson Doh! moments. I was copying the code into this post and then realised that I was actually using the value of the username item that has changed in the first parameter which attempts to get the userid:
    htmldb_util.edit_user(
    p_user_id => htmldb_util.get_user_id(UPPER(:P18_USER_NAME))
    ,p_user_name => UPPER(:P18_USER_NAME)
    ,p_web_password => x_default_pw
    ,p_new_password => x_default_pw
    ,p_developer_roles => x_developer_privs
    ,p_group_ids => x_group_ids);
    and quickly realised that this would not work as it was a value that could have been modified. so I created a new hidden item to store the original and modified the call to:
    htmldb_util.edit_user(
    p_user_id => htmldb_util.get_user_id(UPPER(:P18_ORIG_USER_NAME))
    ,p_user_name => UPPER(:P18_USER_NAME)
    ,p_web_password => x_default_pw
    ,p_new_password => x_default_pw
    ,p_developer_roles => x_developer_privs
    ,p_group_ids => x_group_ids);
    and it works as expected.
    Thanks for your help.

  • Gnome Alt+F2 auto-complete not working

    Hello,
    When pressing ALT+F2 and typing some command the auto-complete does not work.
    Already tried backing up and removing both ~/.config/dconf and ~/.gconf and it didn't fix.
    Also one thing to notice is that other users on the same machine doesn't have the problem.
    Any thought?
    Ps: It was here since before 3.2 update and didn't get fix after the update.
    Thanks

    I have the same problem. Tried using the mouseover to the top-left corner and typing the command. Also invoking the superkey. When I start typing in everything freezes.
    Update: I did open applications using the gnome-terminal       $ application-name &
                  to start firefox with no problems.  Also did move away /.config/dconf and /.gconf .   Still the same.  When it freezes all I can do is a hardware reset. very strange     doing it in Linux, i tell you.
                 This isn't happening before I added any Online Accounts. Somebody has to rethink this much integration with the Cloud I think.

  • Gnome-shell keyboard shortcuts do not work with only conky running

    This is best described by a video showing the bug. You can see the video here http://www.youtube.com/watch?v=tZWdExRxq-I.
    Description
    The gnome-shell keyboard shortcuts like Alt+F2,Alt+F1 and the media key shortcuts do not work if conky is the only program running. However if I open any other application like gedit or vlc or firefox or anything then the keyboard shortcuts work.
    This is not a bug due to any upgrade or anything...I just installed arch linux 4-5 days before...and then installed conky 2 days. However I just noticed that the bug was due to conky. If conky is not running it all works perfectly...How do I solve this problem?
    Hope I provided sufficient information....

    I'm having the same problem. I ended up putting
    gap_x 1595
    in my conkyrc (1080p display) to force it back to the right side. Took a little bit of trial and error, but at least it works as it is supposed to and is placed where I want it.
