  • gnome shell with very high CPU usage

    - by 501 - not implemented
    i'm running ubuntu gnome 13.10 on my dell latiude e6510 with a i5 m560. The I5 comes with a embedded Intel HD 3400 Graphics. The average cpu usage of the gnome-shell is by 160% it's to high, I think. Is there a problem with a driver? If i call the command glxinfo | grep OpenGL it returns: OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits) OpenGL version string: 2.1 Mesa 9.2.1 OpenGL shading language version string: 1.30 OpenGL extensions: Greetings

  • Get the Windows 7 Start Menu Back in Windows 8 with Classic Shell

    - by deadlydog
    I just thought I’d give readers a heads up that you can use Classic Shell to get the old Windows 7 style of start menu back instead of using the new crappy Windows 8 metro start screen; plus it’s free and open source .  You can still access the metro start screen with Shift+WindowsKey or Shift clicking the start menu button.  This program also defaults to showing the desktop on startup instead of the metro start screen (but that can be disabled), and is super configurable and has tons of options to tweak it just the way you want if you are picky like me   The only thing I would say is when installing the app, only install the Classic Start Menu; you don’t need the other ones. You’re welcome, and happy coding!

  • Ubuntu 11.10 Gnome 3 shell doesn't have the Activities menu or launcher

    - by Kelly
    I installed it from apt-get and it only has Applications and Places instead of the Activities menu, it also doesn't have the dock or launcher. Using the super key does nothing, as neither does mousing to the upper left corner. I have also installed the tweak tool, but it looks like all the settings are not being applied to the UI. Am I missing something. I have never used Gnome 3 before as I recently upgraded from Ubuntu 10.4, which I believe was Gnome 2 for the shell. I have been reading the documentation on the Gnome site and it says there should be an Activity menu and other items that aren't there. Thanks

  • How can I run a Perl program when I don't have ssh or shell access?

    - by Christopher
    I just installed an IRC bot, B****X (Don't ask, I don't know - the real name is not censored). I did all of the configuration and chmod'ed the pl files to 755, but running it won't work. My host does not allow SSH/Shell (which is how the documentation says to runs he script), but just going to the URL usually works because of this. However, I get a 500 (Internal Server Error) error. I have logged errors and you can find them at http://services.cl58tools.co.cc/irc/errors.txt Thanks in advance

  • Specify private SSH-key to use when executing shell command with or without Ruby?

    - by Christoffer
    A rather unusual situation perhaps, but I want to specify a private SSH-key to use when executing a shell (git) command from the local computer. Basically like this: git clone [email protected]:TheUser/TheProject.git -key "/home/christoffer/ssh_keys/theuser" Or even better (in Ruby): with_key("/home/christoffer/ssh_keys/theuser") do sh("git clone [email protected]:TheUser/TheProject.git") end I have seen examples of connecting to a remote server with Net::SSH that uses a specified private key, but this is a local command. Is it possible? Thanks

  • How to run a shell command and selectively ignore the status?

    - by Walter Nissen
    I've got a shell script that I would like to stop with an error on nonzero status most of the time, but in some cases I want to ignore it. For example: #!/bin/tcsh -vxef cp file/that/might/not/exist . #Want to ignore this status cp file/that/might/not/exist . ; echo "this doesn't work" cp file/that/must/exist . #Want to stop if this status is nonzero

  • Using cp command in linux shell, how do I copy a whole directory into another directory?

    - by Dmitry Supranovich
    I have a directory, let's say, "work": ~/work/ This directory has some sub-folders (d1, d2...) in it and files in these sub-folders. I want to make a backup copy in the same folder, so it would be like: ~/backup/work/ However, when I use cp -r ./work ./backup the folder "work" is not copied, only its subfoders (so now it's ~/backup/d1 ~/backup/d2...) Any idea how to make it work? I'm quite new to shell, so I'm missing something :)

  • how to send text to a process in a shell script?

    - by Martin
    So I have a Linux program that runs in a while(true) loop, which waits for user input, process it and print result to stdout. I want to write a shell script that open this program, feed it lines from a txt file, one line at a time and save the program output for each line to a file. So I want to know if there is any command for: - open a program - send text to a process - receive output from that program Many thanks.

  • Reliable alert dialogs from the shell

    - by intuited
    I'd like to have a message pop up in response to various system events, mostly in order to be able to set reminders for myself from a shell session. There are a few ways to do this; zenity seems to be the most polished. However, I've found at least two problems with zenity: Messages do not appear on all workspaces. I tried using the gtk option --screen to control this, but they just appear on the current workspace regardless. So if I am switching workspaces as the message comes up, I will not see it. Messages do not appear above all other windows. Specifically, if I am using guake, a new zenity message will appear below the guake window and I won't be able to see it. I tried a few other apps a while back. Both gmessage and xmessage exhibited problem 1; gmessage also exhibited problem 2. I did find that kalarm, which can be scripted from the command line, worked acceptably, but I'm trying to avoid running the KDE stack if possible, and would prefer something lightweight with zenity's versatility. It seems that it might be possible to arrange for these problems to be resolved by setting the WM_CLASS, but I'm in a bit over my head there. It might also be possible to make modifications to the window after it launches with a script, but again I'm not sure where to look for resources on that.

  • python: os.system does not execute shell comand

    I need to execute shell command in python program (I have ubuntu). More specifically I want to create graph using graphviz in python script.

  • Ubuntu 12.10 Unity & Gnome Shell problems

    - by user109292
    I'm experiencing some problems since I decided to upgrade Ubuntu to 12.10 version two days ago. Firstly, I cannot select the Unity environment I previously used on 12.04 without opening the terminal with Ctrl+Alt+T and typing setsid unity. When I select the Unity environment on the account page when I start the computer, it automatically switch back to Gnome and launch my session. I tried to set back Unity using the setsid unity tip, and it worked fine. But after few minutes, everything freeze and I cannot control anything anymore. The only option left is to press the Power button of my Asus EeePC and switch everything off. Question 1 : What can I do to get my Unity environment back on 12.10 from the start, without using the terminal every time? What should I do to prevent the all system to freeze once done? Secondly, and since I cannot use Unity for new, I'm using an other interface, GNOME Shell. What's bothering me is that the Activities bar (let's call it like that, 'cause I don't know the proper name) and the Internet bar (or any bar from any other window) cannot merge into one another, reducing the display of the screen I'm actually using to peanuts! Question 2 : Is there a way to merge those two bars? Or is there a way to hide the Activities bar when I'm not using it like on Unity environment?

  • Gnome-shell partially freezes

    - by user568021
    My specs: Ubuntu 12.04.1 LTS, Gnome3, Dell Studio laptop This is not happening all the time, but only sometimes .. totally randomly. When I'm in the middle of some work something totally weird happens. Keyboard suddenly stops working. I can't type, no matter which key I press nothing happens. I can't press Alt+Tab, I can't press Alt+F4, Alt+F2... nothing. Activities button is dead. Also right click does not work...and something even more annoying. I can click on the 'menu' in the top right corner(the menu pops up), but clicking on 'power-off' or 'suspend' option doesn't do anything. The only little thing I can do is: Close the lid of my laptop so it goes to sleep. Than wake it up again. And than it's ok. Everything works. So I guess restarting (or refreshing) gnome-shell fixes the problem. Sorry if the title of this question is odd... I don't know how to properly describe this.

  • Unity install removed window borders, and display drivers.

    - by Vivek Sharma
    I installed unity, used for a while. Then i installed gnome-shell, used it for a while. Now decided to switch back to standard. Gnome is not working the way it use to be. I am using T61 with nvidia-latest drivers. Following issues... Window borders are not showing. Installed compiz settings, and re-check window decorations option. I had to re-install nvidia driver, as when I tried to apply normal visual effects, it said no display driver found. Gnome panel is not coming, and mouse pointer is a "cross" than a "arrow". I then opened a terminal and enter gnome-panel. Panel came and window borders came back. Nothing is showing on desktop, and the right click is also not populating the menu. When i loging, an error message saying, docky did not start and it requires compiz to work. After starting gnome-panel from terminal, i went to systempreferencesAppearance. And selected normal visual effects. It activated, i selected keep the settings. Now when i restart or re-login, everything is gone. I have to run gnome-panel manually, and then re-enable visual setting. Ofcourse i can add gnome-panel in startup applications, but i want to know what has installing unity/gnome-shell has done, that these setting are messed up. I manually removed mutter, as Appearance application was showing mutter installed, cant enable effects. What shall i do to get back a standard gnome-desktop back.

  • Custom daemon script: works, but does not run at boot / startup

    - by pearjoint
    this is Ubuntu 10.10 Maverick. I have the following shell script in init.d that I want to run as a "daemon" (background service with start/stop/restart really) at system startup. There is a symlink in rc3.d. I tried 4 and 5 too. (Ideally this would initialize before graphical login happens and before a user logs in.) IMPORTANT: the script works 100% as expected and required when testing this with service MetaLeapDaemon start and service MetaLeapDaemon stop. (This shell script calls a Python program which makes sure the appropriate .pid files are both created at startup and deleted at exit.) So generally it works fine but now my only issue is why it will not be run at any of the run-levels I tried. I know for sure it isn't run because the log file it normally creates does not get created. As you can see (by the lack of any uid:gid args in the start-stop-daemon commands) this would currently run only under root, is this forbidden in a default setup? Here's the script, pretty much your run-off-the-mill daemon script really: #! /bin/sh DAEMON=/opt/metaleap/_core/daemon/MetaLeapDaemon.py NAME=MetaLeapDaemon DESC="MetaLeapDaemon" test -f $DAEMON || exit 0 set -e case "$1" in start) start-stop-daemon --start --pidfile /var/run/$NAME.pid --exec $DAEMON ;; stop) start-stop-daemon --stop --pidfile /var/run/$NAME.pid ;; restart) start-stop-daemon --stop --pidfile /var/run/$NAME.pid sleep 1 start-stop-daemon --start --pidfile /var/run/$NAME.pid --exec $DAEMON ;; *) N=/etc/init.d/$NAME echo "Usage: $N {start|stop|restart}" >&2 exit 1 ;; esac exit 0

  • Getting output of a shell script in Cocoa

    - by Tristan Seifert
    Is there a way that lets me run a shell script, and display the output in an NSTextView? I do not want any input from the user to the shell script at all, since is is just called to compile a buch of files. The shell script part works fine so far, but I just can't figure out how to run it and show the output in an NSTextView. I know a shell script can be run using system() and NSTask, but how do I get it's output into an NSTextView?

  • Invoking cl.exe (MSVC compiler) in Cygwin shell

    - by barcarole
    I'm heavily using Cygwin (with Putty shell). But, it's quite tricky to invoke cl.exe (i.e., Visual C++ compiler toolchain) in the Cygwin bash shell. Running vcvars*.bat in the bash shell doesn't work obviously. I tried to migrate VC++'s environment variables to Cygwin, but it's not that easy. Is there anyone who ever tried to run VC++ compiler in Cygwin bash shell? Thanks, JJ
