I would like to run an interactive python script in tty1 on startup. This script requires user input outputs relevant data.I also need this script to be run as root as it accesses USB devices (and has to detach kernel drivers).It is an infinite-loop script, so I also want to be able to ctrl+alt+F to tty2 to actually login if needed
View 1 RepliesThis problem has to do with Python's interactive help (To get to the interactive help, just type help() at any interactive session). I like to browse all my installed Python modules, to see if I can find something that would be useful for my hobby programming projects. However, recently, typing modules (which is the command to list all installed modules) freezes the interactive session.
View 1 Replies View RelatedI installed Ubuntu 10.10 on my 32gb flash drive. Just one large partition for the OS and about a gig for swap. Worked fine. Booted to USB on two computers and a laptop at home. Fine. Figured I'd try it on a work pc for the sake of testing a random computer. Well I stick the drive in, boot up, select usb from the boot menu and bam Ubuntu starts loading. I look away, it's cool ubuntu's loading. Well I turn back and it's a black screen. It's "<username>@whatever login:" or something close.
I use the username and password I created during installation and what I used to login to the computer like fifty million times while booted into Ubuntu. Well, invalid login. The first time I installed this OS on this drive I updated it through the update manager and rebooted. Next thing I know I type in my username and password, hit enter, and bam black screen, some stuff, then im asked to login again. Now after this next iteration I am faced with yet another faulty login screen. What is up with this OS?
I installed windows 7 and recover grub from the karmic livecd successfully. Now I can access all the OS in my machine. The only weird issue that I have is that there's no login promote in tty1-6 any more. When I switch to tty1-6, I can only see a flashing underline promote. But I can input anything in tty1-6. How to get tty1-6 back?

View 3 Replies View RelatedI need to run a script that prompts the user for some input and takes action based on that input. It must run at the end of the login process, after the desktop is displayed.I tried putting it in ~/.bash_login, but it didn't run. Do I need to tell /etc/profile to run ~/.bash_login? I thought it looked for it & ran it if it was found.
A related question would be - Can I make it so the terminal session that is running the script be the only thing that the user can do? In other words, they can't click on anything on the desktop or in the panels and have it run until after they respond to the input request.
I tried most methods suggested on many sites to install drivers
## through the additional driver panel only
## through the Nvidia.run file I downloaded
## through the terminal using apt-get
All failed to start ubuntu gui it takes me to the console login and I noticed it says "saned disabled" edit /etc/..something. This problem made me install ubuntu again three times and every time I activate the driver then install the driver Nvidia.run or through apt-get and both leads to a black screen tty1 login. So what to do now I installed and removed many things and I won't reinstall ubuntu again. Also I typed compiz and this came on:
root@ubuntu:/home/sherbieny# compiz
Xlib: extension "GLX" missing on display ":1.0".
compiz (core) - Fatal: Root visual is not a GL visual
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :1.0
Launching fallback window manager. I want to install properly so that I can start normally and enable the extra visual effects and the custom effects. Please elaborate the steps clearly

nvidia-detector it says none
and when I enter: nvidia-smi

A new and very exciting error everyone now also the windows 7 that I have besides linux has also crashed and cannot open the login window. I don't know whats happening all I know is that few hours ago I logged in to windows normally now I cannot login to either one of them and the funny part is: I'm working on my thesis on this computer and I cannot work anymore and I'm supposed to meet with the professor on monday.
I am trying to assign a user account on RHEL5 Server a non-interactive login but I am not sure if this is the correct command: useradd useraccount -s /sbin/nologinAfter I issue this command, I try to log in with this account and it says the "Administrator has disabled this account" when I enter the password. Does any one know if the command above is correct?
View 2 Replies View RelatedI am having trouble distinguishing between login and interactive shells as they relate to terminals. I understand that a login shell is what is started when you login, and an interactive shell is used by scripts and such. I also get that terminals will use an interactive shell by default. What I don't understand is why interactive shells have no prompt by default. Is their a way to get an interactive shell to inherit the normal PS1 prompt? Is it considered bad to do this? Would it be better to have terminals start login shells, and if so why or why not?
View 7 Replies View RelatedBefore you say you shouldn't do that bla bla bla. I know why i shouldn't.
However i have a problem with running sudo commands from a non interactive command line script run using plink.
The automated script needs to use chown and give the current user ownership of some files and folders created by another user.
I can't use things like sudo -s etc as it requires that i enter a password.
I have setup public key authorization in order to login. Do i have to give the root user a password and log in as that. I would prefer not doing this but if that is the only solution i guess i'll have too.
I just build a couple production SLES 11 machines and I'm using an ssh client to connect. However the ssh client forces me to use keyboard interactive login. How can I turn this off so I can use the normal username / password?

I have a situation where I am in a non-interactive shell. I have tried from within my non-interative shell to spawn an interactive shell but my output still does not goto me. Isn't there a way I can somehow go into /proc or somwhere and make the output my /dev/tty1? Or some way else to remedy this?The situation arises because I drop from my restricted shell environment (a sort of CLI interface), into the actual Linux shell. I cannot change the code of the CLI environment I am just faced with being in the linux shell environment and its non-interactive. Its very annoying to have to put > /dev/tty1 after every command I type.
Not to mention it seems damn near impossible to get pagers like more and less to work properly when your in a non-interactive shell.
I want to be able to do
sudo ./program.py
instead of always having to do
sudo python program.py
What do I need to change?

I have a ubuntu 9.10 machine which is left 24/76, as my "download server". I have Vuze/Azureus installed, which I control mainly through the HTML UI, so rarely log into the machine.
Currently, when the machine restarts (not often) I have to log in via NeatX, and run Vuze. I then disconnect, and use the HTML UI.
Is it possible to set Vuze to run automatically, on startup, without the neeed to log in ? If I did this, where exactly would it be running ? As what user ? And what would happen if I then logged in, and ran it in a session ?
I'm using tty1. Lets say I am listening to music there can't I do another thing at the same time read or writing to files or plus can the default login take me there instead of tty8.

But it bugs me that I have to log inand remain so, just to run an app who's interface is not even required mostof the time.Unfortunately, my provider imposes a montly volume. Nice big volume, but notimposible to run it dry. On the other hand, they count nightly traffic atonly half to actual volume.So I'd like to be able to start ktorrent at a certain time after midnight,and interrupt it at dawn. Or maybe just shutdown the machine at dawn.
