have you ever tried to type into xterm ? (output of 5-11.1): Code: xscreensaver-command -lock xscreensaver-command: no screensaver is running on display :0.0 If it is working for you, which version of xscreensaver do you have?
View 1 RepliesAlthough 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 -

I'm having some problems getting my screensaver to work automatically.If I start the screensaver config program then it gives me this message: "The XScreenSaver daemon doesn't seem to be running on display ":0.0". Launch it now?" If I click yes then my screensaver works exactly as expected.How can I get the XScreenSaver daemon to start automatically?
View 3 Replies View RelatedI'm having trouble trying to make a script. What I want to do is check if xScreenSaver is running in my user account. If not, run it. If it's running, kill it.
So this is the script I've made:
Code:
The problem is that I've echoed the output of $(pgrep -u $(whoami) xscreensaver) and it always seems to add 4 numbers to the pid, even if the pid doesn't exist. What do I mean by "doesn't exist"? That no xscreensaver is running in my user, and if I run pgrep -u $(whoami) xscreensaver in bash, I get not output, but if I run the command though the script, I get (for instance) 4050. If I run it again, I get 4054, and again 4058... etc. What the hell is going on with that?
Can someone please tell me how I can use grep to display all users running a particular command.

Using the Gnome desktop and screensaver
At some point, I suspect since the last kernel upgrade, I've begun experiencing a problem when the screen locks: I tap a key on the keyboard and the monitors wake up, but I get no "unlock" dialog. I can usually Ctrl-Alt-F1, login and gracefully reboot the system, but sometimes I have to hit hard reset. For now I've disabled the screensaver in "System -> Preferences -> screensaver" (I assume that'll stop the problem), but that's not an optimal solution.
This issue was resolved in Lucid and Maverick; now it's back... This happens after only 2-3 minutes, even when the screen saver is set to activate after 20 minutes. I believe this has something to do with ACPI power management.

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.

If I reboot, it works corectly until I run one of those two. Not sure about any other audio type of program. Bad updates, virus, or something else?
I have a bash script that messages the user periodically. Is there any way in the script to check if the screensaver is running, so the script doesn't spam messages while the user is away? The xscreensaver process is always running in the background, I've noticed.
View 5 Replies View RelatedI apologize if this is the wrong place to ask, or if this has been asked before, but it has been bugging me for some time and I have not had any luck with it. I imagine that my problem is not unique to my circumstances, but here goes.I am running Arch Linux, and quite frequently watch videos, particularly flash, in fullscreen. However, eventually, the screensaver appears, and starts dimming the screen. I have the screensaver set to run whenever the computer is 'idle'. Does anyone know a way to either.Stop the screensaver from appearing when in a flash video or watching other video?Stop the screensaver from appearing when a flash video or normal video is full-screened? Heck, even..Let the screensaver know that my machine is not idle when watching flash.
View 1 Replies View RelatedThere'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..
Anyone noticing intermittent problems with the screensaver not kicking in or the display not sleeping? This is in gnome under F11.I have the Power Management Preferences set to put the display to sleep after 30 minutes of inactivity and gnome screensaver is configured for 5 minutes idle time.On a regular basis, I'll leave my computer come back anda) the screensaver hasn't kicked inorb) the screensaver kicked in, but the power management features didn't kick in to put the display to sleep.It seems to be an intermittent problem and usually it goes away after I restart X, but then at some point it comes back. In the past, I've gotten in the habit of being logged in for weeks/months at a time but I find that I can't go more than a few hours without logging out and back in or else the screen won't go to sleep.

View 9 Replies View RelatedUsually I open 5 terminals. And since each of those 5 terminals prints it's tile as: "username@username-laptop: ~" It becomes very hard to see what is what. So, I would like my terminal to always change it's title automatically to the program that I am currently using.
So, if I type "irssi", the title of my gnome-terminal-window, should change to: "irssi" for example.
I am connecting to remote Linux PCs via ssh, to update software and do other tasks. I want to send a notification to the remote PCs screen (eg, "Do not run program X, it is being updated now"), so the users do know what is happening.
Is there a reverse way for ssh -X host so I can connect to a remote Linux machine and run notify-send and it appears on the other display?
I'd like to display GUI apps running on one Linux box on another machine.

I am having acer aspire 4736 laptop, i installed opensuse 11.4 64bit after installation completes system restarted and icompleted post-install configuration . then when i restarted again and selected to boot from opensuse first splash screen comes but within a second it went off again it comes only for a moment & went off but system is still running there is no display for all text as well as graphics modes(alt+ctrl+f1......f7). i restarted my system again and again it started well only once or twice for lots of time .
I checked in failsafe mode also there in display properties it is not able to detect moniter. i selected default settings it is showing some x11 org not found like that error.
So I'm teaching myself some scripting to try and create a fairly simple photobooth type affair... I've got gphoto2 playing fairly nicely with my canon, and imagemagick taking that output and rearranging it to a vertical format...
EDIT:
*smacks forehead*
Fairly simple to do what I needed initially: Code: feh -FZ -D 1 --cycle-once $COUNTDOWN & sleep 2 &
feh -FZ -D 20 --cycle-once $SMILE This shows a countdown from 5 to 1 in images and $SMILE is big that says 'smile'
So my question is thus... (fairly basic but I can't get my head round the use of & and sleep in this context) what's the best way to call my gphoto instructions (or a script with them in) mid way through the above code?!
'feh code'
sleep 5
'gphoto code'
this kind of thing seems like the way, but the'sleep 5' and 'gphoto code' doesn't start until feh is finished in this case?
I have 8 cores system, but I only want to use 4 cores of it. Are there any commands to show which cores are running tasks?
View 1 Replies View RelatedI'm running ubuntu 10.10 (with the macbunu theme if it matters). From there, I'm running an application on a solaris system and forwarding the X11 display back to my ubuntu/gnome display with the follow command "ssh -X <solaris-host>". Everything seems to display correctly so far except for what I would describe as the alert boxes. The problem is they are invisible. I know it's there because I have mouse pointer jumping turned on and the mouse jumps to the default button and if I click on it the alert box flashes and but disappears. The disappearing is normal due to the button press. So it appears the alert box is present but invisible until I click a button but disappears immediately because of the button press.
View 2 Replies View Related I added XScreenSaver 5.08 to her applications list. We've had issues with XScreenSaver and want to either disable or uninstall the application. We cannot figure out how to disable XScreensaver and revert to the original screensaver app that came with the system. When I use Snaptics Package Manager to either 'completely' uninstall', or just 'uninstall' the message says that I will uninstall the 'desktop'.
Does this mean I will uninstall only the desktop version of XScreenSaver applilcation? Or, does this mean I will uninstall the system desktop (in this case Xfce)? I'm a little hesitant to punch the button in case I blow off Xfce desktop! Our goal is to either disable or uninstall XScreenSaver 5.08. Then be able to use the screensaver that came with the system.
I have three boxes with lenny debian recently installed. I'd like to be able to display X apps running on host1 and displaying on host2. "xhost +" would do the trick for me if I could get it to work but as far as I can tell it does nothing. (BTW, I'm aware of the security risks. This is not a concern for me. I'm safely behind a good firewall. I'm also aware of "ssh -X" but that won't quite solve my problem. See the long version below.) I suspect that Debian secures the xhost command out of the box in some way but I can't seem to figure out what it is. If that is true and someone can show me how to reset it, or direct me to appropriate documentation I think that would solve my problem.
Here's the long version:
What I really want to do is play xbattle with my kids but I need to be able to display the board to three different screens. In xbattle the command line is: % xbattle -red me -blue host1:0 -green host2:0 {and more stuff of no consequence to my question}
This opens a game board for player red locally, player blue on host1 and player green on host2. Or at least it should. If there is a way to make this work with "ssh -X" (or anything else for that matter) I'll be happy to use that instead, but so far as I can tell "ssh -X" only lets me redirect the display back to the one I ssh'd from whereas I need to direct to multiple displays to run xbattle.
I recently installed xscreensaver in order to change some settings on some of the screensavers I have. All is well until I lock the screen. I do not like the look of the password entry window. the one that came with the GTK2 theme I use looked great and I was wondering if there was a way to tell xscreensaver to use that one instead of the one that it uses by default. Also, whenever I restart my computer I have to open up xscreensaver and tell it to kill the gnome-screensaver daemon and then start the xscreensaver one. Is there a way to automate this process?

View 3 Replies View RelatedI recently installed Xubuntu on a 5+ year-old Acer Aspire laptop. In spite of how the root, swap and home are volumes in an LVM2 group on top of a fully-encrypted harddisk, it's quite swift this computer isn't for me, however; it's for my old man. It's been my pet project for the past few weeks, as an exercise in making Linux both highly secure and user-friendly, so that even a technophobe like him could use it without fear of identity theft if it ever gets lost or stolen. I recently shipped it off to him...
The weakest part of security, however, I fear may be the screensaver, which is why I ask. I've searched and searched and cannot manage to find any information on security hardening practices (apart from banal advice such as "always choose a secure password" and "never log in to an X-session as root"). What I want to know is, just how safe is a locked screen? Also...is it technically possible with the right tools to get a core dump of a running computer and thus extract the block device encryption key from memory? I know that your run-of-the-mill thief will just try hitting the power button and throwing in a livedisk, but hey, you never know. Edit: found.

I recently dist-upgraded from Debian 5 to 6 (squeeze). Since then, the xclock I run from my window manager's start script isn't displaying correctly (it displays only a "0"). The thing is, if I run the same command in my start script in my terminal, it works just fine, as it has always done...
I use this rather "old" X applications because I like my programs simple/not buggy/fast, and it's resulting a rather annoying problem (being that apparently nobody else has it...).
All other programs in my start script (gnome-terminal, emacs, xmodmap, etc) are working with no problems whatsoever.
My window manager: sawfish
Command to run xclock in my start script:
Code:
xclock -digital -brief -geometry -0+0

How to set xscreensaver as default
I just enjoy xscreensaver, but I like to have it as default, when f12 start. I am not very deep in details of Fedora, but still, can anybody guide me to set this as default ?
How can I run xscreensaver whenever the lid is closed? I'm running Ubuntu 10.10 with the awesome window manager.
