Ubuntu :: Prevent Mouse From Deactivating Locked Screen?
Mar 17, 2010
I recently installed Karmic Koala (desktop edition) on an old PC. Most of the time, the PC is expected to be running in locked screen (i.e. blank screensaver),unless I need to fiddle with something.However, I keep hitting the mouse accidentally.Therefore, I would like to prevent the mouse from deactivating the locked screen and presenting the unlocking dialog. I.e. only direct keyboard press should invoke this action

I have a HP Pavillion DV7 laptop running Ubuntu 10.04, and I am having some problems with Ubuntu handling a network connection. Every so often, I leave my computer in locked mode overnight to download something. But, when I do this, the network just deactivates early on [there is a symbol of a blank wireless symbol with a red "?" by it]. Both the wireless and wired network connections are deactivated, and I am using a wired connection. This also sometimes happens in suspend mode, too, but less often. I have to restart my computer before it will connect again, as logging out and back in again does not suffice.

I have a machine running XFCE in a "kiosk" environment. The machine normally runs without a keyboard or mouse, and I remote control it via VNC and SSH.
When the machine starts up, the mouse cursor sits in the center of the screen. I don't want to plug in a mouse or use VNC to move the mouse to the bottom-right corner so that it is not visible, so is there a way to hide the mouse cursor or tell it to move to the lower right when X starts? It would be even cooler if the mouse could be disabled or hidden when no mouse is connected, but re-enabled when someone plugs in a mouse, but that's probably asking too much.

I have successfully installed an ATI EAH4350 (Radeon 4350) to work as a dual head in Ubuntu 10.04 but there is a bug though, which I noticed given the following scenario:
* Dual Head config (Multi-desktop)
* Monitor 1
- Running firefox and terminal
* Monitor 2
- Running WinXP in Virtual Box 3.1.6
- Virtual Box is in full screen mode
- WinXP is showing a flash movie using firefox also full screen mode
* Monitor 2 is configured above Monitor 1.
Sometimes the mouse gets trapped at the top of Monitor 1 (in between the two monitors). Keyboard doesn't function as well but the currently running apps continue to operate "normally". Ctrl + Alt + Fx doesn't work.
What is frustrating is when it happens it's beyond my control. I can't do anything else besides reset the PC.

I can't log in from a locked screen anymore, such as when returning fromeep or hibernation. I can, however, work around the problem by clicking "switch user" and logging in from the GDM greeting screen. Logging in from a terminal also works.I recently had a problem where /etc/passwd, /etc/groups and some other files were deleted. But I have restored them - otherwise I couldn't log in at all.

In Ubuntu 10.04: if the screen has been locked (automatically by the screensaver or user-activated using the top-right menu) pressing the power button doesn't initiate shutdown. Is this a bug or is it a configurable option?I would expect to either get the usual 60 second shutdown delay or a graceful shutdown right away.

I am building a small Ubuntu box made for our clients to listen to an audio stream. At startup, I have scripts that start the audio stream, then locks the screen so clients can't change any settings. It works flawlessly.
However, if a client has to shut down the box, they can't. Note this is a headless unit, no monitor, keyboard, or mouse. It will ONLY be used to play streaming audio. I need for the client to be able to safely shutdown the unit by pressing the power button. But, when the power button is pressed, ubuntu asks for the user password. Is there a way to just make the system shutdown without entering a password?

I went to lock the screen when I got up from my computer. I came back and there was a black screen. I tried hitting different buttons nothing worked. I rebooted and still went right to black screen. I can get into recovery mode but I can't figure out what's wrong with the computer. Can someone give me a hint. My father is very good with ubuntu but he said that he would just reload the os on it. But I really don't want to go thru that process all over again.

I am having problems with hibernation. When I choose to hibernate, the computer starts to do so, and powers off, and almost immediately it wakes up and comes back to the locked screen. I am using 32 bit version. Hibernate used to work properly on Hardy. I checked that my swap space is more than twice my RAM size.

The usual apologies if this is already dealt with somewhere.I want to use the global hotkeys to banshee when the screen is locked. Possible?(And on a side note, how do I bind the key combo "ctrl+shift+<" ? I get ctrl + shift + >, which it then doesn't react to)

i need to knw is the a way to configure the ubuntu desktop to prompt for a password when relogin after the screen is locked?
it asks for a username and password a at the login prompt if i relogin after logging out out but when i lock the scree by pressing ctrl +alt + l and try to relogin it will not ask for a password , it just let me log in automatically to the pc , i think this is a security issue cos anyone else can login to my pc without prowiding credentials

I have upgraded to 11.04 today and I have hit a slight snag. In 10.10, I had it setup so that it would run a custom script when an audio CD was inserted into the DVD drive. The CD would mount regardless of whether the screen was locked or not. Since upgrading to 11.04, the CD will only mount when the screen is unlocked.Whilst I can appreciate the security benefits of this (if it is indeed intended and not a bug), is there a way to be able to enable discs to be mounted automatically, whether the screen is locked or not

I've got an HP Netbook with Jaunty installed, and I've got an older Dell laptop running Debian.A friend of mine, on several occasions, has told me that when I left my computers unattended he could do some kind of series of key-strokes, and then a window comes up and he says that he can change the password for my account.I've asked him to show me how he does it, but he never will because he doesn't want me to be able to thwart himIs he lying, or is it for real? if it's for real, how do I go about changing it so that it can't happen anymore?

I've been running Ubuntu Maverick as a fresh install since release, and for the last 2 days, I'm having to log in twice! This is only on a locked screen, not on reboot or switch users. After the first login, I see the desktop for a second, then the screen goes blank. I wiggle the mouse and the login screen is there again. The 2nd login goes as normal.
I have gradually been installing things as I need them over the week since install, but I can't pin it down to any of those. It's getting pretty annoying when the screen saver kicks in!

Ubuntu 9.04 works fine, I have just installed Ubuntu 10.04 Lucid Lynx without problems, it runs fine but after a while the screen starts flashing and the only way out is to reboot with ctrl-alt-del. First of all I get a pale purple screen with blocks of random colour in the middle then it goes on to flashing between two screens. In one the top half of the screen is vertical black and white stripes and the bottom half is black, in the other it is a terminal screen with this distributed across it:
Starting common Unix printing system cupsed
Pulse Audio configured for per-user-sessions
Enabling additional executable binary formats binfmt support
Checking battery state
On the latest occasion the text was "could not write bytes: Broken pipe" repeated all over the screen, followed by "checking battery state".

When I first started using Fedora 10 I had a bit of a play with the "Leave Message" button that appears when you lock the screen. After you type the message and click save, the next time the user logged in the messages would pop up.
Ever since Fedora 12, when I leave a test message, after I log in nothing pops up. This happens on two different computers so I don't think its an obscure hardware problem.

Is there a config file to toggle whether the screen is locked after hibernation? I looked all over preferences but if it's there, I missed it. In Ubuntu, the screen was always locked after waking up. In Squeeze, it's going directly to desktop. It's not a biggie but you never know when someone might try to access your account so I kind of liked that it would wake up locked. Maybe it's doing that because I'm the only user on the system?

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.

While I was away from my computer a friend changed my keyboard layout to a random layout thinking he could revert it via mouse actions only. Unfortunately, by the time I returned, my screen was locked. Now I cannot unlock my session to get back in to the KDE session to restore the correct keyboard layout.
However, I can log in to a console. In the console (e.g., Ctrl-Alt-F1), the keyboard layout is unchanged, so I can edit any text files and make any other changes required. How can I change the KDE keyboard layout from a console? I'm running Kubuntu 10.04. There is no .kderc file in my home directory. And Xorg.conf doesn't contain the settings either. I'm not sure where else to look.

I put power settings to never, but the screen still goes to sleep and moving the mouse you have to login.What I really want is no login screen, and I suppose if you were watching a vid it would go dark?

I have Ubuntu 10.10 installed on a laptop. The laptop has an external 19" screen connected to it through the VGA port. I am not using the laptop screen (because it is small and flickers constantly) but only the external screen. When I shut the laptop lid the external screen blanks. There is no option in the power management dialog and the option "Activate screensaver when idle..." in the screensaver dialog is unchecked (which I would like to re-enable to blank screen when idle for x minutes). How can I get Ubuntu to leave my external screen on when the laptop lid is closed?

I installed Ubuntu 11.04 today as the main OS on my laptop.I had deleted my XP partition, and repartitioned it according to a guide I had found. (http:url)......Basically it was setup like this: 500mb ext2 primary partition, has the grub folder, I believe this is either the '/' partition, or the '/boot' partition 2gb swap space logical partition
10gb ext4 logical partition -- this is either the '/' or the '/boot', it contains the 'bin,boot,cdrom,dev' etc folders 243gb (the rest of my hard drive, with the exception of a partition that contains documents and files from my XP OS, formatted to NTFS) ext4, this is the one that has all my desktop/documents/etc folders.After Ubuntu was done installing, I had some message pop up about installing an ATI proprietary driver for my ATI graphics card (an ATI Radeon HD 4330, I believe, I may have messed that number up). I installed it and rebooted, no problem.
Next, I had another update window pop up with 198 items checked and ready to download and install. I went through all of this, and rebooted, again, no problem.Next thing I did was install some apps that were essential for me to have to use for my work (an ide, chat programs, etc). No problem with any of that.Last thing to install was the OSE Virtualbox, and then I installed WindowsXP Pro and Windows Vista Business, then installed the guest addition addon for VB. This all worked without any issues whatsoever.
Time goes on, and I notice my computer is heating up much more than (seemingly) normal. I begin to wonder if its my graphics card. So I shut down the computer and let it cool down. Reboot, and no problem, still working fine.Then I opened a couple of apps and tried a simple game (can't remember the name) I believe it was a simple 3d topdown, as I wanted to test my graphics card. This is where things seemed to start to go wrong. My laptop began hanging, not even allowing me to access the terminal via ctrl+alt+f2. The screen flashed and I saw the blue/green/grey fuzz that I get when the graphics card is starting to heat up too much. Then everything hangs and I can't do anything at all, including move the mouse. I did a hard reboot (I believe this is what you call pulling the plug/pressing the power button, correct me if I'm wrong). I then rebooted, saw a chkdisk, then it booted seemingly normal, but it hung right after the purple screen after the grub screen.
This is pretty much where I'm at right now. I strongly suspect the fault is with the ATI drivers, but have been completely unsuccessful in my attempts to fix it. I've googled just about everything I could think of, along with searching these forums. I've tried just about everything listed in the forums, but to no avail.I've tried the commands that are supposed to purge the ati drivers, but all I get are errors that say they can't remove the 'virtual drivers'.
Right now I'm booting off a live cd, so I know the computer still works fine, just not my actual installed OS. I'd really like to get the issue resolved without having to reinstall, as it took quite awhile just to get it usable in the first place, but this has already taken so much time, I may just resort to that if we can't solve it any other way. Got too much work to catch up on as it is.As a re-instated note, perhaps if you have any tips, but not particularly about fixing the OS, my laptop (I'm strongly guessing my graphics card) is heating up much more than normal, compared to that when XP was installed. Is this more than likely just a driver issue, as is the rest of it? Also, I did have Compiz installed, though I didn't choose for it to be installed, I believe it came pre-installed. I've heard it could cause some issues, though I have no idea as to the validity or relation to this particular issue.
Edit:
I just remembered while searching for a solution, I found a post somewhere that said something about the information not being sent to the monitor from the graphics card properly, thus no desktop. I'm guessing that'd still fall under the driver issues, but again, I'm unsure. I would think that wouldn't be entirely true anyway, since I can still see my mouse fine, just no desktop, only a black screen.

I'm running Ubuntu 9.10 otherwise flawlessly on a 2007 core 2 duo Macbook. Right now its set up to triple boot with OS X Snowleopard, Windows 7 Ultimate, as the other operating systems. I'm asking because I'm frequently having to force my system to power down after shutting down from Ubuntu, and I'm concerned that I could be corrupting files and damaging my hardware.

I have a 2004 Dell Inspirion 2200 that has a bad hard drive. I have Linux Mint on a 4G flashdrive. Everything is fine (so far) except that the only way I can get the internet to work is to plug in a hard line, then activate the driver (it downloads), then search for the wireless router. Here's the issue:I don't understand why I have to plug in a hard line to activate the driver. Shouldn't it stay activated once I download and activate it?
