Please consider reorganizing this page to start with the current stable release of Fedora and the easiest way to run Sugar with it.  Follow that by sections for alpha/beta versions of Fedora  Sugar, a short section with links to SoaS, and then links to subpages for ARM, PPC, & older versions of Fedora Sugar. Guidance for GNOME on Fedora and other peripheral content should also probably be on subpages.  --[[User:FGrose|FGrose]] 11:45, 30 June 2012 (EDT)

====Keyring Password Explained====
 what do you have to enter when connecting to wlan, the keyring password or the wlan-password?
 first i must enter the keyring password (root password here) and then i entered the wireless password
 the keyring-password should not be your root password, it should be your users password so automatically unlocking could work
 it may happen but during current session, after i reboot it appears again
 ok, it is the keyring issue, assuming your distro has configured keyring correctly, changing the password should work
 root pass?
 change the keyring password to your users password
 in settings ?
 in seahorse
 system settings?
 as user (the login-keyring)
 keyring is a way to store your "gnome" passwords
 So, with one password (the keyring one), you "auto-type" the passwords it contains
 if the keyring-password is your login password, it's automatically authenticated
 keyring stores the passwords encrypted with the according keyring-password, and automatic unlocking works by getting the password through pam on login through gdm and then use  it to unencrypt the passwords - and that can only work if your login-password is the same as the keyring-password

 why doesn't gnome 3 display "interactive dialogs" when applications ask for input
 yes, also from gnome 3
 when you run the shell script from nautilus, it doesn't display a dialog
 "Enter passphrase for ..."
 you can use zenity for that
 try moving /usr/share/gdm/autostart/LoginWindow/gnome-session-check-accelerated.desktop somewhere else
 didn't know you needed anything additional for that.. was it always like that or did gnome 2 have that by default?
 maybe thats the seahorse/keyring integration, that stuff has changed quite a bit in 3.0
 but i thought you meant a more generic approach of showing dialogs from scripts
 i'm actually doing the ssh-add from a process spawned by a pygtk app
 if it is only this specific case, you should probably still use keyring/seahorse (whatever should do that now) as it would not be passing around passwords unencrypted between processes (at least afaik)
 worked!
 do you somehow run gdm with a different driver or some weird setup like that?
 so it's not possible to get the old behavior, and it needs some additional code to get it to work with seahorse/keyring?
 which distro is this?
 fedora 15 beta
 i've tested the same code on fedora 14 and linuxmint (both gnome 2)
 when the ssh-add {key_path} process is spawned, the GUI dialog appears asking you to type in your passphrase
 ssh-add succeeds, and them the rest of the pygtk app continues
 it doesn't even care whether the key is password protected or anything
 i think there needs a daemon to be running that doesn't get started by fedora
 this happens both in standard and fallback mode
 try launching seahorse-daemon


====AutoStart====
  ln -s /usr/share/applications/xxxx.desktop ~/.config/autostart/
  don't remember if I had to manually add it to the startup apps (run
  gnome-session-properties) or using a preference in xxxx itself, but I
  have it running on login on my laptop. The icon shows up in the
  notification tray - mouse to the lower right corner to bring it up -
  this is where all legacy tray icons will show up.

==== List of Autostart programs when starting gnome-shell====

====='''move intro screens that are too large for 800x600'''=====
; alt+f7 and then the arrow keys
; alt+f8 Resize
; shift and arrow keys

 It's worth nothing, for Metacity >= 2.13.2, that if the window doesn't have a
 minimum size hint larger than the screen then Metacity will now force such
 windows to be onscreen (by shrinking and moving them as necessary).  If the
 window has a minimum size hint larger than the screen, then the user can use
 '''alt+left-click-and-drag (or alt+f7 and then the arrow keys) to move the window
 upwards''' (including moving the titlebar offscreen) in order to get to the
 forward button.  Yeah, that's just a workaround for windows that are too large,
 but it may be helpful information for those waiting for the UI changes to make
 the window usable on 800x600 resolutions.  :)
 clip....
 why not use a keyboard shortcut. the "next" button is marked "forward" so i hit '''alt + f''' and guess
 what, i was able to successfully install the program.

====Reload shell ALT+F2 r  (reload)====
: use to recover Applications lists if they go missing and after alacarte edits

====http://live.gnome.org/GnomeShell/CheatSheet====
:How to show user pictures on the GDM LOGIN screen
::Click "my account" on the top panel lets me edit the picture, and 
::adding a picture will show it on the GDM login screen.

If you hold down Alt, a 'Shut Down' option appears in place of suspend.

====Alt+Tab switches between windows====
: hot corner = upper left switches between shell and running applications
: '''Alt+F2 allows entering a command to launch an application.''' 
       the Shell simply always behaves so there's exactly one empty workspace.
       So when you start a session you have one workspace.
       As soon as you run something it goes into that workspace and
       you get a second empty workspace. As soon as you put any app into that
       empty workspace, a new empty workspace is created. If you remove
       everything from any workspace, it will disappear, so there's still only
       one empty workspace at the bottom of the list. So, there's never any
       need to manually add a new workspace. Pretty neat system.

====GNOME 3 is not expected to work in virtualized environments====
       I've just installed F15 alpha in a virtualbox machine and at the first boot I 
       get a gnome 3 error explaining that it can't be fully initialised because 3D is 
       not supported.
       GNOME3 is not expected to work in virtualized environments where
       hardware accelerated graphics are not available.

       From http://gnome3.org/faq.html ...
        The GNOME 3 desktop does require hardware accelerated graphics
        in order to provide a cutting-edge experience however, and the
        complete GNOME 3 experience will only be available on computers
        capable of this. Do not worry though: GNOME 3 will come complete
        with a fallback interface which will provide an excellent
        experience in the absence of hardware acceleration, and which
        incorporates many of the improvements that can be found in GNOME
        3.
        -------------------------------------------
       test Digest, Vol 85, Issue 60, Message: 7
        It's kind of a definition issue. GNOME *Shell* requires acceleration.
        But technically GNOME 3 does not; the fallback interface is still
        considered to be 'GNOME 3'. So you do need acceleration to get the Shell
        interface that's the 'big new thing' in GNOME 3, but still, if you don't
        have acceleration and you get the fallback interface instead, what
        you're running is still GNOME 3. Just GNOME 3's fallback interface.

        In any case, VBox with 3d accelleration enables and 128MB for video memory
        is not sufficient for GShell.  (VBox 4.0.4)
       Message: 13
        Also, on that last note, we should clarify that right now Shell doesn't
        work even in virtualized environments where accelerated graphics *are*
        available, e.g. VirtualBox with appropriate hardware and drivers. In
        theory it should be possible to make this work, but in practice it
        currently doesn't.
        So there's two angles we can approach this from; make Shell run with
        software GL, or fix up Shell to work with virtualized graphics
        acceleration passthrough. But it's not at all guaranteed that we'll
        manage either in time for f15. 

        The minimum memory required is 1GB, due to anaconda changes.
        When you see "populate_rootfs" in the panic, it's caused by that.

==== MacPro and f15 Boot====
*Clips from #fedora-qa 04/04/2011 MacPro and f15 Boot
 I have a macbook pro and have run fedora 14 on it with great success. 15 alpha, on the other hand, is not going well. The installation comes saying something about "installing   *** on EFI ***"
 which i just dismiss/ignore, but when i try to boot after installation has completed, it wont. Just saying something like "no file found". Should i do something
 special to install 15 alpha on a EFI system?
 Yeah... you may have to run gptsync (I think that's what it's called)
 no, you don't need to install again, but you will need to gain access to the installed partitions from another system (whether it's a Fedora live image)
 referring to the gptsync that is provided be rEFIt
 I formatted the partition to make space for a working distro. i have refit installed and my mbp boots to that at startup by default. that didnt make 15 alpha work. 14 did though
 you may need to enter the boot partition tool from the rEFIt menu and when it asks to run gptsync, say yes
  okay. I will try to install again later and do that. Thank you so far. Will get back to you guys
 I belive anytime partitioning changes occur on a macbook, you do need to run gptsync.  Since the EFI implementation by apple isn't fully compliant with the standard, extra  steps  are required
 you don't need to reinstall ... just run gptsync from the rEFIt menu
 just need to get your partitions synced up
