Ubuntu :: Can't Lock Screen - Pressing "Lock Screen" Does Nothing

Jan 3, 2010

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.

Ubuntu :: Num Lock Doesn't Work / When Pressing Num Lock And Typing Numbers, Nothing Happens?

Jun 23, 2010

I'm wondering why the num lock doesn't work in Ubuntu anymore? When you press the "num lock" key, you're supposed to be able to input the numbers along with + - * / and decimal point. When I press num lock and try typing numbers, nothing happens.

I've done a google search and this is a well known problem that nobody has fixed. In Windows it's never a problem.

Seems such a shame that the great Ubuntu and Linux are so good for stability and speed, but can't get a simple num lock working.

Ubuntu :: Lock Screen Not Working (screen Saver Getting Activated)?

Slackware :: KDE 4.4.5 - No Lock Screen - No Screen Saver

Aug 23, 2010

What happens is that I resorted to deleting my .kde directory after my kid destroyed my profile where title bar, menu, konsole get broken. After deleting, I login again thus regenerating the .kde directory. To avoid my kid from messing my desktop, I tried to lock it. It does not lock.

It just need a KDE full restart perhaps since when I login the other day, it now works.

I'm updated to Slackware current for almost a month already and have not played a lot on KDE desktop (busy programming stuff).

However, on day I tried to lock the desktop in KDE to avoid the kid from destroying my cool desktop setting, but it didn't lock. Cool, so I tried screen saver and add an option to lock the screen.

When I test screen saver, it displays. But when I wait for 1 minute(I set it that way), it doesn't fire up. Not even after 15 minutes which I think the default.

It usually work before (several months ago) using the lower version of KDE. It is just last Saturday that I noticed it.

I tried to dig the profile management but I could not find anything relevant there.

I'm trying to use 'gnome-screensaver-command --lock' to lock my computer so that when my girl is on it I can **** her off

I can run the command from the terminal and it works just fine, but when I ssh into my computer and try to do it, I get the error

Ubuntu :: Freezes Sometimes After Screen Lock?

Mar 31, 2010

Sometimes after I enter my password after the screensaver has locked the screen, it will not take my password (even though entered correctly). It seems to lock up. After about 2 mins it says something about a time-out (wish I could do screencaps). Then it will reset and have a gray window the same size as the password input window but on the upper portion of the screen, and a password entry window as normal, but in the lower part of the screen. This time, it accepts the password and logs me in.This is a 2-part post.First, how to bypass having to wait for the timeout (for whatever is timing out).The second is to see if anyone knows an answer to the problem and a fix.After it freezes, hold CTRL-ALT and tap F1.This will taking you to a virtual terminal. Log in with your username and password. Then type:

$ pkill screensa
This will match gnome-screensaver and kill the program that is frozen. You then need to type

Ubuntu :: Continous Screen Lock ?

Jun 9, 2010

I am experiencing a really annoying issue with ubuntu 10.04. Wether the "lock screen when screen saver is enabled"option is ticked or not, it will anyway request me to insert the password.

And that's but the lighter problem: Screen saver keeps poping on while I write, browse and whatever, and changing its properties won't help at all. It just keeps pestering me! (while i'm writing this, i've already had my screensaver popping in about 15 times)

And last but not least, even if I log as administrator and unthick the "request password"... it will always keep asking ... what to do?

Ubuntu :: Can't Come Back From A Screen Lock

Apr 29, 2011

Living with others, I've made it a habit to lock my laptop if I walk away from it (Ctrl+Alt+L), but with the recent upgrade to 11.4 I've run into a problem: when I go to unlock my laptop it just gives me a black screen instead of the "enter your password" menu. All I get is the mouse.

The only work around I have for this is to log into a TTY and then restart the laptop.

In case it's significant, the exact process I go through is as follows: Lock my screen (Ctrl+Alt+L), close the laptop lid (power management is set to just blank the screen instead of suspend), walk away for 10+ minutes, open lid, and then I run into my error.

Ubuntu :: Lock Screen When Suspending Or Hibernating?

Dec 8, 2010

How can you do that in lubuntu 10.04? In xubuntu 9.10 I could do that, if I use gnome-power-manager and gnome-screensaver, and use gnome-power-manager's icon to suspend/hibernate, but I don't see that kind of option in lubuntu.

Ubuntu :: Running Command After Lock Screen?

Jan 15, 2011

So I have a script that runs from 'Startup Applications'. That works fine. However, I also want it to run after I unlock a locked screen such as after suspend or a screensaver. I have mod3+t as a shortcut to it, but it would be nice if I could get it to run automatically.

Ubuntu Multimedia :: Playing LP's Cause A Screen Lock-up?

May 10, 2011

Last week I had a total screen lock-up, which I overcame by rebooting using the reset button. At the time I was playing solitaire (sad, I know!), while listening to a vinyl LP, the setup being turntable > preamp > line- in socket, and running JACK Audio Connection Kit. No other apps were running, but I had played several LP's before the lock-up occurred. I have 1GB of memory installed, but could it have become overloaded playing the LP's, and thereby caused the lock-up? I'm running 10.10

Ubuntu :: 11.04 Hanging After Going Blank In After The Lock Screen?

Jul 7, 2011

Ubuntu hangs after the lock screen menu disappears. When it goes into the lock screen and the menu disappears Ubuntu stops responding. Moving My mouse or typing on my keyboard doesn't help. The password screen does not appear. It does not appear to be this bug: as it stops responding within a second of the screen disappearing. I have confirmed that nothing is wrong with my monitor or video card using my brothers setup.

Ubuntu :: Lock Screen Not Working After 10.10 / 11.04 Upgrade

Aug 11, 2011

after getting my keyboard and mouse working (URL... not even when I was compiling kernels from floppies that came in the back of books did I have to work so hard to get the KEYBOARD working, sheesh), I have a mostly working system.However, Lock Screen does not work in any way, shape or form:

- It doesn't work via the keyboard shortcut Ctrl+Alt+L
- It doesn't work if I select it from the Power button on the upper-right
- It doesn't work if I press the Power button to suspend (even though all the correct things are ticked/unticked in gconf-editor)
- It doesn't work if I switch users and back

Now, I do have a laptop running 11.04 and its Lock Screen *does* work. The only difference I can find is that the laptop says gdm is running screensaver.If it shouldn't be running, why else might Lock Screen not be working?

Fedora :: 15 - Unable To Lock Screen

Aug 8, 2011

I'm using Fedora 15 with Gnome 3 on my laptop. I don't restart the system unless there's an update that requires me to, preferring to use the Suspend feature instead. However, I noticed that after an uptime of a few days, the screen doesn't lock anymore. Neither the shortcut 'Ctrl+Alt+L', nor the terminal command 'gnome-screensaver-command --lock' seem to work. I'm sure restarting the system will enable me to lock again, but I don't think I should restart just to get this feature back.

Does anyone know why this happens? Is there some other way to lock the screen?

OpenSUSE :: Lock Screen Key Shortcut In 11.2?

Nov 13, 2009

Possibly a silly question, but here goes...In 11.1 and below I set a key shortcut to lock the screen when I push Meta+L. However, I can't seem to find a way to do this in 11.2. I tried the following:* I looked in the keyboard shortcuts settings page and didn't see an option for screen locking* I tried right-clicking on the screen lock button on the panel and setting the shortcut, but that doesn't seem to have taken effect* I googled and searched this forum, but no luckThe default key combo seems to be Ctrl + Alt + L, which works, but I have years of muscle memory for pressing Meta + L, so I'd like to preserve that if possible

CentOS 5 :: Lock Screen As Root?

Aug 11, 2009

I've googled for the answer to this but every thread has the same answer "don't log in as root". For once I'd like an actual answer to the question if possible. All of the jobs that I run are all through the root account and I'm constantly using ssh into other workstations and servers to change config files or whatnot. I'd like to be able to lock the screen when I take short breaks or head out for the day while being able to leave jobs running. For example I am currently backing up a server onto another one and would prefer not having to stop the jobs when I leave for the day(there's over 400GB to move).
