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:

I can use the gconf-editor to disable the screen-saver lock and set it to activate when its idle. But no matter what I change /apps/gnome-screensaver/idle_delay to, the ScreenSaver UI is never updated and stays at the default 5 minutes. There seems to be no link between the slider bar in the ScreenSaver Preferences and the value that lies at /apps/gnome-screensaver/idle_delay...
The reason why I'm doing it through gconf-editor is so a start-up script I have created can use gconftool-2 to alter settings for certain users on login.
Is this broken in Ubunto 10.04 or am I looking in the wrong place.

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.

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?

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
$ gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/hibernate false
[Code]...

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?

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?

Is there a way to set Linux to automatically log in to a specific user account and at the same time lock the screen? I want to save time and trigger various software that always should start up on boot, while leaving the computer unattended during startup (extra important and practical for remote control boots), by enforcing a 'screen lock' so that no-one can see what happens behind the login screen without entering the login credentials.

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!

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

After some idle time Slackware hangs up/freezes. When, for an example, i turn on music i can hear it on idle time but after some time music still plays but i'm losing picture (monitor detects no signal), num lock is locked, led on keyboard are turned on but won't turn off while pressing num lock. I've switched off power saving options in Slackware and on bios setup.
My spec is:
X4 620 (without overclocking)
AMD 760G (Radeon HD 3000)
Catalyst 11.5 for Radeon graphic.
BTW - computer works fine with Windows. Also, with Slackware i can work for an hours, many hours and everything is fine but as soon as i leave it for some amount of time = it hangs/freezes. There is something wrong with hibernation. Not always computern is turned off correctly. TV is switched off, slackware logged off but i hear drives working and cooler fans. It should be switched off completly.

Anyone have an alternative to gconf-editor for changing the idle dim time? I have a Vaio, which hasn't exactly been compatible with ubuntu but I've been making it work.What I'm looking for is an alternative, like the the one I'm using to control the back light (nvclock).

I have experienced that the button in my main menu "Lock Screen" does nothing, so I can not lock my screen. What could be the problem? Is there any command in terminal what I could write, so I can see is there an error output or something?
I am using Ubuntu 9.10, GNOME.

How to make the system boot faster by removing the idle time between 5s to 10s? bootchart attached. It is Ubuntu10.04LTS by the way. One more hint, the screen black out for ~4s after "Begin: Running /scripts/init-bottom... Done." I don't know what is going on during that 4s, but my best guess is there is a way we can get rid of it.
Bootchart can be found here:

My hard drive all of a sudden starts to read and write all on its own for around 15 seconds at a time while at idle or while I am just browsing the net. At first I thought it was from cron running but I have that disabled.

Running RHEL5 and because of the environment that we are in we have to disable the users being able to change the screen saver. I have tried using the gconf-editor to see if I can disable it but don't know if that is the correct way of doing it. I also looked in /etc/xdg/menus and really don't want to miss with that.

I have removed gnome-screensaver, and to the best of my knowledge, it has not been replaced it with any other screensaver application.I have set System->Preferences->Power Management to never blank the screen. However, Ubuntu still blanks the screen if there has been no user interaction for a while.

When I hit Alt+Ctrl+L my system is starting the ScreenSaver but not locking the screen. The keybinding is correctly set. This is happening in only root account but in another user account it works perfect !

My VLC player blocks screensaver while playing, but my monitor still turns off when watching for some time. I did a few searches, but I don't see any good keywords so I'm starting a new thread.
