Is there a way to take a screenshot just before the "shutdown" terminal command? for example "sudo shutdown -h 90" for 90 minutes timer shutdown, and just before turning off to take a screenshot.
View 1 RepliesIn my office there is a department where the access of internet & intranet is very limited. I've been given a task that I should add a script which would automatically take screenshots of the PCs. The script works fine, but I can't make it work with the cron jobs. There are many methods given on the internet to grab screen, but none of them works with cron.
View 2 Replies View Relatedafter having far too many problems with other brown-coloured distros, I moved my MythTV box to SuSE (what all the other machines here use). Everything is working, EXCEPT for one thing: automatic idle shutdown. I cannot get MythWelcome to shut down the machine automatically (choosing shutdown now from it's menu does work). The log shows sudo: sorry, a password is required to run sudo (sudo -n) or the infamous "no tty and no askpass". (plain sudo)
I have added /sbin/shutdown to the sudoers file, and I can run sudo /sbin/shutdown -h now from the terminal and shutdown without a password... but sudo will NOT run from mythtv. I've even tried adding a special exception to the sudoers file, "Defaults !requiretty" with no luck. This is a dedicated frontend/backend with no user access (doesn't boot a desktop manager; goes straight to Mythtv) so I'm no too worried about potential security; the machine is on a LAN and cannot be accessed from the WAN side.
I need a script for shutdown the system automatically if the system is not disturbed for last 10 minutes.
By the way i am using RHEL 4 in my system.
I found this script on another forum post (HERE) from a couple of years back.It doesn't work anymore for some reason and I'm looking for some assistance in making it work now. I really need to cut down my electric bill and my son is constantly leaving his desktop on for hours on end.Any gurus out there up to the challenge?I am attempting to re-write the "inactive=" line using w instead of who but I'm not having much luck yet.
View 3 Replies View RelatedI have installed Ubuntu as wubi (next to windows 7). When I expect the computer to shut down (either to hibernate or as part of, you know, shutdown), it doesn't. All the programs end, I am logged out, but I still have a picture on the screen (ubuntu default picture).
View 7 Replies View RelatedI'm trying to make my system automatically shutdown once the battery level is low, but still without success. I've tried kpowersave, gnome-power-manager, kpower, klaptop but none of these worked for me. Well, I can't imagine I would be that stupid, but simply it doesn't work. In all cases mentioned above (kpower, klaptop, gnome-power-manager) I've tried to setup the laptop to shutdown once the defined level is reached, but the laptop never actually switched off unless all the battery was drained.
Btw. I think all the above mentioned apps only work once the user is logged in. But I'd like the solution to work also when the PC is on without anyone logged in. I thought I could write a bash script based on parsing of acpitools output and define it as a service, which would monitor the battery level, but I simply don't believe there isn't any functional solution to this.
I'm trying to make the power manager NOT automatically shutdown / sleep / hibernate when battery power of my laptop reaches critical
I am surprised there isnt an 'NO ACTION' option for that in power manager
I've tried editing the acpi-supper in /etc/default bu couldn't find a solution in there nor in the /home/user/.gconf/apps/gnome-power-manager/ directory
I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?
when my pc boots and shuts down my monitor goes into 'input out of range' mode for a bit between the gui and the text only phases of boot/shutdown.is there a way to fix this? or where to start troubleshooting?also, when it shuts down it hangs after coming back to the text only part

View 9 Replies View RelatedI cannot locate shutdown log for Linux shutdown to check various activities carried out during shutdown. I can view Startup Log which is availble on console>Applications>System Tools>System Logs.
I have included Shutdown/Startup in dbora, so that Oracle 10gR2 Shutdown/Startup will be automated during OS Shutdown/Startup.
I want to check Shutdown log because Oracle Shutdown was not running, as from $ORACLE_HOME/shutdown.log contains no entries, where as startup log contains latest startup details.
That means here 2 issues are there. One, I want to locate OS Shutdown Log and the other being Why Oracle Shutdown not getting executed.

View 3 Replies View RelatedI frequently need to take screenshots of a game (flash-based, running inside a browser), in particular it's statistics screen which is shown when I hold the TAB key. The problem is, when I take a screenshot, either by pressing PrintScreen key or by pressing a custom-defined shortcut, the game responds to this keypress and hides its statistics screen, so the screenshot doesn't contain the information I need.I figured out how to overcome this using a custom application launcher icon; but this requires using the mouse which is rather inconvenient.define a shortcut that wouldn't be processed by the active application? Or maybe there's some screenshot utility that does this out of the box?
View 2 Replies View RelatedOk here's what I'd like to do:
Take a screenshot, or some other way of saving the visual output of a java applet [URL], and saving that as an image, without having to manually do it (open browser go there, and take a screenshot).
I guess this would be most easily done using a script of some sort, but I have no idea how to go about doing this..
I would like to do this, so I can use this image to update my conky every 30 secs or so (got that part figured out ).
I was gathering some screenshots to use in a tutorial on how to do something in Unity. For the most part that went well... however I did find an unfortunate quirk.When I Right-Click any of the items in the Unity Launcher panel, and they bring up the submenu (for example I did the modification to add Pics, Docs etc to my Home Folder in the Launcher) I then cannot do a screenshot using my "PrtSc" key on my netbook. This only happens when the submenus are visible. Unfortunate because I wanted to get a screen shot of the submenus.
View 2 Replies View RelatedI've been experiencing a weird delay between me pressing the printscreen key and the screenshot dialog appearing. The delay is about one second, and is happening even though gnome-screenshot's delay key is set to zero in gconf-editor. This delay is making it difficult to capture things which disappear quickly, and I'd like to know if there's any way to make the screenshot dialog appear instantly.

I use mplayer to play my media files. Occasionally I want to take screenshots of media I am playing. I use the -vf screenshot option to take screenshots which generates shotxxxx.png. The issue is that all those png are not compressed and usually large. When dealing with Hi-Def media they are extremely large, each is 4-5 MB in size at the least. Is there a way I can set the option for compression of png images. If I use imagemagick the same files get compressed to like 1.5MB of png file.
