General :: Is It Safe To Lock The Screen With The Gnome-screensaver?

Mar 8, 2011

USB driver bug exposed as "Linux plug&pwn" or this link.Two choices [GNOME, Fedora 14]:

1 - use the gnome-screensaver

2 - use the "switch user" function [gnome menu -> log out -> switch user]

So the question is: which one is the safer method to lock the screen, if a user leaves the pc? Is it true, that using the [2] method is safer?Why do i think this? - The gnome-screensaver is just a "process", it could be killed. But if you use the log out/switch user function, it's "something else". Using the "switch user" function, could there be a problem like with the gnome-screensaver? Could someone "kill a process" and presto...the lock is removed?Could the GDM [??] "login windows process" [e.g.: a picture of it] get killed and the "lock" gets owned?

p.s.: if the [2] method is safer, then how can i put an icon on the GNOME panel, to launch the "switch user" action by 1 click?

Sep 7, 2011

It's very disturbing when making a Kiosk application, every time the lock screen and screensaver shows up, also many popup + battery or updates shows up. Where and how can I completely disable the lock screen, screen saver and alerts via a configuration file or from the terminal? I have the tried following but nothing works: failed

vim /etc/default/acpi-support
;LOCK_SCREEN=true
failed
$ gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/suspend false
$ gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/blank_screen false

Ubuntu :: Lock Screen Without Screensaver Running?

May 7, 2010

Is there an easy way to lock my computer screen without a screensaver running? What I'm trying to do is basically fire up a web browser or terminal window that I want to watch/monitor but lock my screen so that it can't be changed unless you know the password to log in as that user.

Ubuntu :: Lock Screen After Sleep/Hibernate But NOT Screensaver?

Jul 29, 2010

running 10.04 Netbook edition. I would like my screen to lock after the netbook goes to sleep but NOT after it enters the screensaver. is this possible? i use my laptop to read in the university a lot and to save power tell it to go into black screensaver after a minute of inactivity. if i enable the lock option i have to enter the password each and every time after the black screensaver activates. but if i deactivate this option and then put the netbook into sleep/hibernate mode it doesn't ask for a password (which i would like) is there any way configure separate passwords for these instances or are they firmly linked?

Ubuntu :: Screensaver + Lock-screen Works But Idle Time Not Detected?

Dec 6, 2010

I am running 10.04 (i686) inside kvm-qemu client. The host is a headless 10.04 (x64).The issue is that the screensaver does not activate after a certain period of idle time (1 min). I can successfully activate the screensaver by running gnome-screensaver-command -a. It appears, then, that idle time is not being registered correctly. There are some very sporadic logs in daemon.log:

Code:

./daemon.log.1:Dec 1 11:01:24 myserver gnome-session[2166]: WARNING: GSIdleMonitor: IDLETIME counter not found
./daemon.log.1:Dec 2 12:35:53 myserver gnome-session[19953]: WARNING: GSIdleMonitor:

Ubuntu Installation :: Wrong Configured Gnome-screensaver (black Screen)?

Feb 24, 2010

all I wanted to get was the "rss-glx"-package as additional screensavers. I am not proud of the results:So I used the Synaptic tool, and since that time the gnome-screensaver shows a black screen instead of any GL-animation in the preview-windows (the small and the big one). The simple screensavers still work (e.g. the Gnome feets).I propably made it worse when trying to uninstall gnome-screensaver and installing xscreensaverxscreensaver crashed on each preview (if the screensaver was installed) and printed an "exited abnormally" (yellow lines on a black screen).Then I was trying to get the original state back - without any "rss-glx".Still not succeeding, the GL-screensavers show nothing except a black screen (e.g. AntSpotLight).So what do I have to do to get back the original state (or to run rss-glx)

Ubuntu :: Install WINE Screensaver In Gnome-screensaver Possible?

May 19, 2010

There's an OSS screensaver on windows that I love called PixelCity (links:blog post, github). it's pretty cool. and it runs fine on my Ubuntu (Karmic 9.10) with wine.Is there a way I can tell the gnome-screensaver about it so I can use it as one of my screensavers? I'm still fairly new to Gnome and the whole "screensavers as themes" thing is still confusing me.I've found my themesdir and tried to create a .desktop file for it, but obviously I've gotten something wrong as it just doesn't show when I open the screensaver prefs dialog, no error, no message, it's just not there.

Installing the xscreensaver packages added the extra screensavers I was missing, and I'm a pixelcity away from perfection..Of course the perfect solution would be if someone ported the screensaver natively to linux, which shouldn't be too hard as the source is open, it already runs on openGL and tries to confine most windows stuff to a single file. But I don't know C++ or 3D code or win/linux internals so I wouldn't know where to start..

OpenSUSE Install :: Will Not Authenticate After Screensaver Lock Out

Oct 1, 2010

I've just installed 11.1 and so far things seem to work OK. When I left the machine the screen saver kicked in and wouldn't let meback on with my password I chose during installation (and the only password I chose!) Re-booting the machine sorted the problem...until next time! I have now disabled the lock out for the screen saver so things ought to work now, but why did it do this? New with openSuse!

General :: GNOME Screensaver Widgets

Apr 10, 2010

Is there a way to add widgets to a Gnome screensaver? I think this can be done with KDE 4, but I've never liked KDE very much. I'm a programmer and comfortable with writing code if needed.

I'd like to be able to:

See the weather and forecast
Control Rhythmbox
Use a flash card widget for reviewing musical concepts

The reason I want these on the screensaver is that I have login restrictions. I would like to be able to do a very limited subset of activities without having to log in.

Ubuntu :: VMware Player Stops Screensaver/lock Engaging?

May 9, 2011

I don't know if anyone else sees this, but I get some odd behaviour when using VMware Player sometimes (Ubuntu 10.10, VMware Player 3.1.2 build-301548, dual monitors).My screen locks after 5 minutes of inactivity. I run a Windows XP VM under VMware player occasionally for certain things and that has a screen-lock time of 15 minutes or so. When running the Windows VM in full-screen on one of my two monitors (not tried it on a lower res), if I place the mouse cursor on the XP VM screen and leave it for > 5 minutes, the screen does not appear to lock. I can come back to the machine and still interact with the Windows XP machine and do what I like. If I move the mouse cursor outside the bounds of the XP VM screen, then the whole screen goes black and presents me with the password prompt to unlock the machine

General :: Wake From Screensaver Directly To The Login Screen In Ubuntu?

Mar 16, 2010

I've got Ubuntu 9.10 with a user account for my wife, and one for myself. "Wake-from-screensaver" should result in "choose user" without having to enter any password. I know how to do that in Windows, but I'm not good with Linux (yet). get past the login screen without passwords (after booting, and after choosing "switch user"), but once the screensaver kicks in and I wake it up again, the system does not present the "choose user" screen. Instead, it either turns off the screensaver and presents the desktop of the most recent user, or (if the screensaver is set to lock the screen) prompt for the user's password (which can be handily surpassed by clicking the "switch user" button and choosing the same user again). So, the login ("choose user") screen has been dealt with. How do I make the (any) screensaver return to the login screen at wake, rather than to the current user's desktop? Windows can do this, I'm sure Linux can too - but how?

Ubuntu :: 9.10 - Login On GNOME Or GNOME Fail Safe Mode

Mar 12, 2010

I have installed Ubuntu 9.10 on my Dell GX240. I have severe difficulty logging in. If I try to login on GNOME or GNOME fail safe mode , I just cant get in . I keep getting the login screen again. I am able to go into terminal mode. Sometimes I have to try upto 100 times to login in GNOME or failsafe mode. Once I am in everything is fine. Is there a way to do some troublshooting? Also transfer to USB sticks is very slow - sometimes as slow as 1MB per min. Is this normal with Ubuntu?

General :: Automatically Set Screensaver Activation Back At 30 Minutes Each Time The Normal Screen Is Reactivated?

Mar 16, 2011

I'm running Fedora 14 and set the screensaver (in System>Preferences on the Gnome GUI) to activate after the computer is idle for 30 minutes. After the screensaver is activated, and a press a key or the mouse, the screen is back to normal -- no problem.After the screensaver has been activated once, however, it comes back on very quickly -- usually in 2 or 3 minutes if the computer is idle. The only way I have found to correct this (and set activation back at 30 minutes again) is to log out and back in again.How can I correct this, and automatically set screensaver activation back at 30 minutes each time the normal screen is reactivated?

General :: Monitor Power And Lock Screen - Ubuntu Lucid

Oct 7, 2010

I'm trying to get my screen to turn off whenever I lock my screen. I know that in Power Management, there's an option to turn off the screen after a set amount of time, and I know about xset dpms force off, but the former doesn't allow me to turn off the screen from the logout menu, and the latter only turns the screen off for a short amount of time (1 minute or so. The screen just turns back on by itself).

Is there a script I can modify to change what happens when "Lock screen" from the logout menu is selected, or is there a script I can add to the panel to lock the screen and then turn the monitor off (and turning it back on when I shake the mouse or something)?

Fedora :: Gnome-screensaver Not Activating

Dec 11, 2010

I'm running Fedora 12 and the last couple days I have noticed my screensaver will not start anymore. I did a yum update a few days ago don't know if there is a connection between the two. I've just started to Google the topic. Found different culprits ranging from dbus problems to buggy code.

I'm using a x86_64 PC running kernel 2.6.32.23-170.fc12.x86_64. My Gnome version is 2.28.2. The Gnome-screensaver version is 2.28.3-1.fc12.x86_64.

Ubuntu :: Removing Gnome Screensaver

Mar 12, 2011

The Gnome Screensaver preferences window is freezing my desktop. I went into synaptic and tried to remove it (to use xscreensaver instead). But synaptic, in removing gnome-screensaver package, wanted to ADD a bunch of packages, lots of KDE stuff (which I don't want). Is there any way around this? If not, is there a way to reset the gnome-screensaver config file (whatever it is) so that it doesn't freeze on startup? This problem arose after I selected a particular screensaver in the gui window.

Ubuntu :: Replace Gnome-screensaver With Xscreensaver?

May 12, 2010

Although xscreensaver is much better and liked by many users, the Ubuntu devs replaced it with gnome-screensaver simply cause -

1) It's integrates better with the gnome-desktop.
2) It follows release cycles of Gnome.

Since the devs and admins won't listen, we users have to clean their **** up and this is the howto - In Ubuntu, the gnome-screensaver is running; but xscreensaver is better, so we need to replace it. The gnome-screensaver runs as a daemon...removing this gnome-screensaver package will remove this executable also -

Ubuntu :: Gnome Screensaver Security Vulnerability?

This sounds like a huge security risk to me, is there anyone who can test this? (Only noticed with game in wine, perhaps you need low level xorg access)
