I'm connecting via ssh to an Ubuntu server that has a physical display attached.I'd like the physical display of the server to remain locked while I'm connected remotely.Is this possible? How? Also, is there a way to automatically unlock the screen for the VNC session, which is made from localhost via an ssh tunnel?
View 1 RepliesThere are often times when the best way to launch an application is from the terminal, but it is a graphical application and after it is launched the terminal is useless.
Examples of places where a terminal is convenient are when a process starts lots of child processes and is also unstable; you can be sure to kill all of its children simply by using Ctrl-C at the terminal. Also it allows me to read program output and to set up the terminal environment to be optimal for the application (for example "unset LIBGL_ALWAYS_INDIRECT")
With GNU screen, I can get around the hassle of having a terminal window open by using something like the following in a terminal window:
Code:
screen
my_command
Ctrl-A d
and then I can close the terminal and the program will keep running. Then I just type "screen -r <Tab>" (the tab will get me my screen session if there is only one such session) in any terminal window, even a tty, and I can get the screen session back and use Ctrl-c or something.
So my question is, is there a way to do this automatically so that a launcher or script will start a screen session, inside that screen session start a process, and then detach from that screen session without me having to manually open and close a terminal and type the commands?
I've done the process with no problem on Ubuntu, but I can't get it working with Lubuntu.
I installed the pam package. I then added the @include common-pamkeyring line to my /etc/pam.d/lxdm file.
Here's my complete /etc/pam.d/lxdm file:

Am I doing something wrong? Does something have to be done differently in LXDE?
I seem to have added all my passwords to the default keyring while using a live session. Now when I log in, I am then asked to unlock my default keyring. I thought if you logged in with a password this wasn't necessary. When I look at my passwords and encryption keys, all my passwords appear in the default folder, and nothing is in my login folder. Is there a way to migrate these passwords. Or is there a way to automatically unlock my default keyring?
View 1 Replies View RelatedI have set my computer to auto-login and as a result, the keyring asks me to enter my password every time I start the computer in order to access the password for the Ubuntu One client.
The whole point of auto-login was to not have to enter a password.
Is there a sensible way to use Ubuntu One without having to supply a password each time?
I say sensible, because I would like to avoid leaving the keyring totally open. I understand the purpose of the keyring, and that it should be locked by default. As far as I can see, the only potential work-arounds for the problem I am having seems to be to set the keyring password blank, thereby exposing all my keys to anyone on the computer. This option obviously defeats the purpose of having a keyring in the first place.
Is there not an option that lets me set that specific passwords are available automatically to specific applications? So that the entire keyring remains locked, but those passwords I deem ok to be unsecured are available to those applications I deem trustworthy? This option seem to exist for network-manager, why not for the Ubuntu One client?
Is this option not available, or am I missing something? If it isn't, I guess that I'll stop using Ubuntu One, which would be a shame.

It automatically locks your workstation when the usb key is removed, and re-activates it when it is plugged back in.
So I've tried finding a solution to this on my own for the past few days (believing it is a simple solution), but for the life of me I can't figure it out. I'm running 11.2 and I have Evolution as a start-up program and I have finally got my wireless working, so it connects automatically at start-up also. I figured out how to have network manager automatically unlock the default keyring, but...
Each time evolution starts up I am prompted to unlock the default keyring. How can I give Evolution permission / access to the default keyring automatically so it can check me email upon start-up without me having to type in my password?
I'm starting the first command in screen like this: screen -d -m -S testen -t lalala watch df -h Now I have a screen session running in background and I can reconnect at a later time. But how can I run a second command (in a new window) in the same screen session?

View 3 Replies View RelatedWhen I lock the computer, and move the mouse to unlock, the unlock screen is invisible and can't be seen. I can still type in my password and manage to unlock, but I can't visually see the screen, nor can anyone leave me a message while I'm gone. This only seems to affect GL screensavers.
View 2 Replies View RelatedI typically have several terminal windows each of which is connected via ssh to a remote server. In each window I work using the gnu screen program, to ensure persistence of the interactive processes in case of a disconnection.
Currently, whenever the ssh connection drops (such as when I put my client computer to sleep overnight) I have to manually and tediously restart the ssh session inside each window, and then in each window tediously resume the specific screen session (e.g. "screen -r 3453" in one window, "screen -r 3462" in the other etc.)
Is there an elegant way to automate this? Specifically:
reconnect the ssh session if it drops, as soon as an Internet connection is detected run the specific screen instance for the terminal window as soon as ssh reconnects
When I unlock the screen, I'm presented with an opaque dialogue (white box), regardless of whether I have a screen-saver or not. This is a cosmetic issue only because I can type my password to unlock the screen successfully, but I'd like a solution. I'm using oS 11.2 with KDE 4.5 (but the issue predates updating to 4.5).This is the only "issue" I've experienced since migrating my laptop (was Windoze 7) and desktop (was MS SQL server 2003) to oS

View 5 Replies View RelatedI'm using wmctrl on an Ubuntu machine to manage windows from a script, that I run inside a (gnu) screen.
If I start the screen session from the local machine, wmctrl works fine, including if I completely close the terminal window and issue the wmctrl commands when connecting to the screen remotely via ssh.
Conversely, if I connect remotely with ssh and start a screen, wmctrl doesn't work (returns "Cannot open display") even if I attach that screen session locally from the Ubuntu Terminal.
I guess there is some hidden screen parameter that doesn't get set in a way that allows accessing the display when it's launched remotely -- any ideas what it is and how to modify it from within a remote ssh-screen session so that that the script can access the windows?
I run into a new kind of problem with Ubuntu 10.4 LTS. The unlock screen dialog that asks for your password when resuming from the screensaver does not show up immediately. Moving the mouse, typing stuff. It does not seem to be a pure display problem, since typing the password does not seem to do the trick. After a while (about 15 seconds), it shows up, though.

using update manager, i allowed my karmic desktop at work to begin the upgrade process to lucid on friday afternoon... i ran out of time, and headed home for the weekend. somewhere along the process, the screen locked. after arriving back at work this morning, i cannot unlock the screen, or even switch users. other threads in this forum seem to indicate that i should've aborted the upgrade, but... i didn't know enough to anticipate problems, and i guess i assumed that given the lengthy estimate to complete the upgrade, i could just pickup the process again on monday.
in any case, cycling the power didn't help, so i downloaded the iso, and have booted to the 10.04 'trial'. i was hoping somebody could help guide me through resetting a password on the on-disk os from the live cd... i'm ok with reinstalling if i can preserve my account's configs & prefs.
This has happened in natty more than once. Once the screen gets locked after long periods of no keyboard/mouse activity (all ok for short periods of time), I don't even get back the familiar unlock screen with password.I get a blank screen and then Io a ctrl-alt-f7Is this a known issue in natty?

View 2 Replies View RelatedSometimes I want to keep something in PDF files, so I print to the PDF "printer". However, if I inadvertetnly forget to check the PDF creation and rather take the real printer (which is usually only powered up, when I really want to print something), printing goes to the real printers queue and nothing happens ... until, possibly some sessions later, I want to print something (on paper rather than PDF) and power up the printer.
Then all inadvertent garbage comes first and chances are big, that the printer gets junk during power up or reconnecting the cable to the computer and then the whole thing is wasting even more paper, since escape-sequences sent to the printer get chopped and misunderstood by the printer.
In order to stop this alltogether, I am looking for a mehtod, to automatically flush the whole printing queue every time when I log out of my ubuntu session.
I know, there is a command lpq to tell which print jobs are pending, I also know the command cancel -Umyname -a, but this requests for my password. I want to kill all those incomplete or pending print jobs automatically.
And how do I hook such a command script into the logoff or shutdown sequence?

View 3 Replies View RelatedI need a way to have screen (or dbus, whatever) to spit out a list of windows (title and number) that are active in a screen session.I'm writing a wrapper for common work tasks. Part of the functionality will check if a certain window exists, and if so let me know. The idea here is to prevent accessing the same machine twice. (although, and override option would probably be needed, just in case, but I digress...) I've searched through the screen man page and don't see anything that'll work. I'm not beyond forking screen and ending up with a custom version. However, I'd like to avoid that if I can.
Edit: I'd like to see something like "screen -S screen_name -window-list" or similar.
