Debian Multimedia :: Lock Screen With Xscreensaver After Suspend?

Jul 1, 2011

I have set up minimal debian installation with pekwm, tint2, xscreensaver and friends. When I press Fn+F4 on my thinkpad or run pm-suspend from root terminal, it suspends just fine (yay), but when I resume, I get instantly logged in into my account. What I'd like to have, is that xscreensaver locks my session after suspend, so that I have to type in my password in order to continiue working.

PS. In /etc/default/acpi-support I have LOCK_SCREEN=true

Debian Multimedia :: Disabled XScreensaver Still Locks Screen

Apr 14, 2015

I'm using SolydX, based on Debian Jessie. XScreensaver is installed and disabled, but it still locks my netbook screen after some minutes and suspend mode. Waking the netbook up brings XScreensaver login window. I'd like lightdm login window to appear instead.

Debian Multimedia :: Xscreensaver Blanks Screen While Watching Movies?

Jun 5, 2011

I'm using Debian Squeeze with Fluxbox and I'm having a problem with xscreensaver. I've set to blank screen after 10 minutos of inactivity, but the problem is that when I'm watching a movie, the screen is blanked after 10 minutes too. So I have to manually kill xscreensaver before starting to see a movie, or I have to move my mouse / press keyboard every 10 minutes to activate the screen again.

I've done some search before posting and I only found something about a SMPlayer's option named "Disable screensaver", but it is already on and it has no effect preventing xscreensaver to work. Here is a screen shoot of my SMPlayer configuration window:


Apparently, xscreensaver isn't being able to recognize that another program is running. Could it be related to dbus?

PS: I had a dbus problem when I first upgraded to squeeze, my multimedia keys stoped working in banshee (whenever I clicked to play/pause/next etc, another banshee process was started), but I solved it by adding this line to my ~/.xinitrc: eval "$(dbus-launch --sh-syntax --exit-with-session)"

Ubuntu :: Not Able To Disable Screen Lock After Suspend / Enable This?

Nov 16, 2010

I recently upgraded from Lucid to Maverick I can't seem to disable screen lock after resume from suspend. It's a minor annoyance, but still a considerable annoyance to have to enter my password every time the computer wakes up.

I've thusfar

1 - changed screensaver preferences to not lock

2 - set the gnome_keyring_hibernate, gnome_keyring_suspend, hibernate, and suspend, values all to false in gconf-editor

3 - commented out the line LOCK_SCREEN=true in /etc/default/acpi-support

BUT am still being prompted for a password every time the computer wakes up from suspend. I'm stumped, what could I be forgetting?

CentOS 5 :: Lock Screen After System Resume From Suspend / Hibernation?

Mar 21, 2009

For the sake of security, I want the screen to be locked after the system is resumed from suspend or hibernation. Now the only way I can do this is to check the options "Lock screen when screen saver is active." in the screensaver preference. But this method is annoying since I have to type the password to quit the screensaver. Is there other way to do this? Thanks.

By the way, I use CentOS 5.2 x86_64.

Debian Multimedia :: KDE Lock Screen Not Working

Jul 11, 2015

Just upgraded to Jessie from Wheezy. The process went smoothly.

I've noticed the lock screen is inescapable. The "Unlock" button does nothing, the keyboard is completely disabled, and all I have is a clock to stare at for all of eternity until I force a reboot. It doesn't hang or freeze, I'm just unable to get out of the lock screen. I've tried configuring the widgets and stuff in the System Settings, but I can't make it usable.

It was working perfectly in Wheezy, and is a pretty important feature that I use all the time when other people are around and I need to leave my station.

Debian Multimedia :: After Suspend - Only Mouse Cursor On Screen

May 16, 2010

I've been trying out suspend occasionally on Debian Testing to see if it works. After the last time though Gnome won't come back up again, I just get a movable mouse cursor and no panels or right-click options even after rebooting. I can switch to text consoles and kill X but starting it again results in the same behaviour. I noticed there have been a few Gnome and Xorg updates lately.

Debian Configuration :: Xscreensaver Cannot Control The Screen

Dec 29, 2010

For some reason I cannot figure out, xscreensaver does not have permission to control my screen. It's present in memory, so the settings app thinking it is not present and asking if I want to start it is odd. Could the the necessity of using VESA BIOS controls to get around bugs in the VIA/S3/Unichrome chipset be the source of the problem? Are there other Linux screensavers that might work differently and might still be able to blank my screen?

Debian Multimedia :: No Lock Screen Appears After Waking Computer From Suspension

Jun 3, 2015

I am running Debian 8 with the Xfce Desktop Environment.

I was unhappy with the lock screen on Xfce so I removed xscreensaver and wrote a short custom locking script, which basically involves using i3lock along with some additional commands to make things pretty. I was able to change the default locking behaviour by modifying /usr/bin/xflock4 to run

Unfortunately, no lock screen appears whenever I suspend ie after waking the computer from suspension I don't need to type a password in. I would like to force Xfce to lock the screen with before actually suspending, but I don't know how to do this.

I know that Xfce runs Code: Select allxfce4-session-logout -s when suspending, but xfce4-session-logout is a binary file which I cannot edit.

Debian Multimedia :: Xscreensaver Randomly Crashes X

Apr 16, 2016

My supposedly stable system was crashing. The problem was one or more specific screensavers--xscreensaver, the display manager (lightDM), and X itself are innocent as far as I can tell.

I'm on a Thinkpad T400 with Debian Jessie (8.4)/MATE/lightDM. I have libreboot and not proprietary BIOS. I like variety, so in addition to installing xscreensaver itself (the unofficial patched jessie version without the "out of date" nag, which I got from, I also installed some extras from the official repository (xscreensaver-gl-extra, xscreensaver-data-extra, xscreensaver-screensaver-bsod). I enabled all the installed screensavers and asked xscreensaver to randomly cycle through them.

To my dismay, after variable lengths of time (usually within 20-60 minutes), when a random screensaver has been on for a little while (I'm guessing as it's about to go to the next random one), X crashes to a black screen. The only way to make the black screen go away is to kill X (which I mapped to Control + Alt + Backspace) then log back in. There are no useful logs anywhere except some cryptic IO error 11 entry in ~/.xsessionerros.

Now for the troubleshooting:

1) First I tried installing a more up-to-date version of xscreensaver (5.34-2), which I grabbed from the sid repository. This didn't work--same problem as described above. Therefore, I went back to the patched version for jessie (5.30-1 from

2) To exclude that the lightDM middleman was the problem, I disabled it and was logging in with startx. Problem did not go away. (I then rigged systemd to log me in automatically and for startx to run automatically once I'm logged in--who needs middlemen?)

3) To exclude screensavers butting heads, I uninstalled mate-screensaver and disabled anything from X that could be interfering (by running these commands in a startup script: xset -dpms; xset s 0 0; xset s noblank; xset s off). Problem did not go away. I kept this startup script nevertheless.

4) Finally, to exclude individual xscreensaver module(s) being the problem, I unchecked them all. Then I wrote down the names of my 20 favorite modules (which include some from gl-extra, some from data-extra, and bsod) and tested them in small batches, running xscreensaver with only 5 favorites checked at a time. After testing four batches of 5 and witnessing all 20 favorites both display and load without any X crashes, I went ahead and selected all 20 favorites. I left the laptop on overnight and in the morning (about 12 hours later) it's still going strong.

One or more particular xscreensaver modules are crashing X, probably at the time they are being loaded to be the next one to show. I think I already spent enough time on this, so don't really care to identify +/- troubleshoot the offending modules.

Debian Multimedia :: Type "xlock" In A Terminal And It Would Lock The Screen Until Came Back And Typed Password?

Feb 10, 2011

When I was using AntiX, I liked how I could just type "xlock" in a terminal and it would lock the screen until I came back and typed my password. I saw that there was no "xlock" package, so googling around, I saw it was replaced with xlockmore and xlockmore-gl, neither of which there seems to be a package for in the Squeeze repositories. I tried xscreensaver, but I prefer the simplicity of xlock (and I like that it doesn't leave a daemon runnig when not in use). Is there a way to safely install it, or should I just be looking for an alternative?

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

OpenSUSE Multimedia :: Full-Screen Video Streaming Lock-up

Oct 15, 2010

When I play a video web stream full-screen, the image randomly freezes. I can still move the mouse and hear the audio, but I can't click on anything, and I can't get out of full-screen. No keyboard commands that I know work, and so I end up having to hold down the power button to kill the machine.

This didn't happen in Ubuntu, so I'm pretty sure it's not a hardware issue. And I changed the power management settings to do nothing, but it still happens. So, I don't know what the deal is. Should I try a different flash player (I have the adobe player as default)?

Ubuntu Multimedia :: 9.10 X64 - Samsung LN40C530 - Screen Lock Up And Become Inactive

Apr 15, 2010

Video card: nVidia G86 GeForce 8500 GT (rev a1) (lspci | grep VGA) Monitor: Samsung LN40C530, recently switch to from a generic Gateway 17" monitor that worked fine I've been using 9.10 x64 from a clean install since it came out and it's been working great. I recently upgraded my monitor from a generic 17" Gateway monitor to a Samsung 40" widescreen HDTV (LN40C530), and that's when the trouble began. At first, the screen would lock up and become inactive. I could move the mouse, but clicking did nothing and the clock wouldn't update. I also could not switch to a terminal via Alt+F1, I could only do a hard reboot.

Then, when it started booting up, I would get horizontal black and white lines (which I'm still getting). Usually, it boots to the white glowing Ubuntu logo as files load in the background (@ 640x480, 60hz). When it tries to bring up the login screen (autodetected 1920x1080, 60z), I get horizontal white lines across. (see pics) Happens booting off both Live CD and HDD. When I use safe graphics mode on live cd, it boots okay @ 1600x1200, 60hz. After installing under safe graphics mode, it gives me a message "no modes available, resolution unsupported".

Right now, I'm back at trying to install 9.10 x64 (Karmic Koala) with either 1920x1080 or 1360x768 @ 60hz. I'm using a DVI out to a DVI/VGA adapter, and a VGA cable between the adapter and the PC port on TV. I've tried default configurations, restricted drivers 173, 185, and nVidia's 195. When I'm able to get to a terminal, I've tried sudo X -configure, but testing w/ X -config yields the same broken result. When I Alt+k+PrntScr, it does refresh but brings up the same white lines. Sometimes it boots just fine and even autodetects as "Samsung 40", but not as of the last 30 or so boots. Let me know where I can start for proper troubleshooting; I'm not sure which log files are important for this issue. Do you think I might just need to create a customized X config with exactly what I need?

Debian :: Blank Screen Upon Resume From Suspend?

Jan 28, 2010

Up until a couple days ago, my computer had no problems suspending to ram. However, now when I suspend, and later hit a key on the keyboard (usually space) to resume, all I see is an illuminated black screen. I can't even open a tty via Ctrl+Alt+F1. I can however ssh into the machine.he only possibility I can think of is that I am no longer running kdm. I just use "startx" to star an openbox-session.

Debian :: When Suspend And Hibernate Screen Goes Black?

Feb 26, 2011

I am having some pain with my new Squeeze installation, I am not sure if I am asking to much of it or it is an easy fix.

Firstly my system is laptop which I regularly plug a second monitor into. The video adaptor is an ATI HD4550 mobile.

My problem is that when ever suspend or hibernate my system, and even sometime when I boot up the screen(s) are just blank, although sometime they don't, it always happens if I suspend by closing the lid of my laptop, and only sometime happend with through Gnome is go ->System->Shutdown->Suspend. This is really annoying.

Another issue which I think is connected is that as I said I have a second monitor (most of the time) and when I boot up then it works until I log in, then a message pops up say the configuration can not be applied and it revert to Mirror mode or it does this thing where it places the second screen inside (virtually) the built in Laptop panel, it will not let me fix this through the monitors dialog just displaying the same message. I can fix this by doing

invoke-rc.d gmd3 restart

This gets as far as killing Gnome them it prints an error the to console, at which point Imopen a new terminal by ctrl+alt+f2 and
invoke-rc.d gmd3 stop
invoke-rc.d gmd3 start

then it works fine and even remember that I set the secondary screen to be the primary monitor through xrandr.

I tried install fgrlx drivers instead but it didn't really fix the issue, so I removed them.

Debian Configuration :: Fglrx System Hang On Screen Suspend

Aug 18, 2015

My system is hanging on screen suspension... And its not the usual hang on "sleep" or others similars, it will happen by only having the screen on stand-by ( eg xset +dpms)...

If I leave for a while the screen will shutdown as expected but computer will completely hang after an indefinite time, it will not respond to outside connections and the will be spinning faster than usual...

Only workaround is to have the screen power save option disabled, in my case, on the KDE settings...

I have tried the most common solution to have "nomodeset" as a kernel option to disable mode setting, but this doesn't seem to work...

Also tried to forcebly reproduce the issue with Code: Select allxset force dpms standby/suspend/off but nothing happens like that...

This issue also only appears with the fglrx driver, open-source works well.
