Missing option to disable Fast User Switching

[Andrew Oakley]

This is an alternative or addition to, but not a duplicate of, bug #185586 .

Due to bug #161106 , it is not possible to have two (or more) users both logged with Compiz (advanced desktop effects). Generally the first to log in gets Compiz and subsequent users do not.

There is no warning, most users will find this counter-intuitive and confusing. Because Switch Users is most likely to be used by families sharing a computer, the users who encounter this bug will generally not be very experienced. They may report duplicate bugs or clog up support forums.

Since bug #161106 is unlikely to be resolved any time soon - certainly not in time for Hardy - then, administrators (those on the sudo wheel) should have the ability to turn fast user switching completely off.

For example, in System - Administration - Users and Groups - Users Settings, a new checkbox named "Disable Fast User Switching".

The result of this box being checked would be:

- Fast User Switcher applet removed for all users
- No Switch Users button on the Quit... applet for all users
- No Switch Users button on the screen lock (after screensaver) for all users

The checkbox would be unchecked by default.

I prefer this alternative (rather than explaining in technical terms that some action has not easily explainable effects, force the user to logout so there are not two users fighting for Compiz).

There's another issue in this setting: the NetworkManager applet is also only seen by one user at a time (even though the other one might have privileges to use it).

This is also related to but not duplicate of Bug #326916. Fast user switching doesn't work with multiseat configured using
https://help.ubuntu.com/community/MultiseatX. I have turned off /apps/gnome-screensaver/user_switch_enabled, and turned on /desktop/gnome/lockdown/disable_user_switching. This disables the Switch Users button on the screen lock (after screensaver) for current user. I have to go to each user and remove it independently. I can remove the fast user switcher applet also for each user independently, but there is no way to remove it/disable it from the following location:

- Switch Users button on the Quit... applet
