====Multiple Machine Caching with yum====

*http://yum.baseurl.org/wiki/YumMultipleMachineCaching

:store rpms in a cache for installation to multiple Computers

====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.

====fix screensize in sugar-emulator====

* Alt+Shift+Tab: Cycle in reverse direction in the window cycler

* Alt+`: Switch between windows of the same application in Alt+Tab

* Ctrl+Alt+Tab: Pop up place cycler

* Ctrl+Shift+Alt+R: Start and end screencast recording

* Ctrl+Alt+D: Show desktop and raise windows back

* Ctrl+Alt+Up/Down arrow: Switch between workspaces

* Ctrl+Alt+Shift+Up/Down arrow: Move the current window to a different workspace

Most keybindings can be viewed under the User Menu -> System Settings -> Keyboard -> Shortcuts

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

ALT F2 gnome-session-properties

====='''move intro screens that are too large for 800x600'''=====

; alt+f7 and then the arrow keys

; alt+f8 Resize

; shift and arrow keys

:https://bugzilla.gnome.org/show_bug.cgi?id=262546

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
