• Wrong notification on GNOME Shell?

  - by audrianore

  I just installed GNOME Shell on my 12.04 a couple hours ago. The notifications are just cool, and I installed shell extensions, and it works smoothly in 1 hour. Then I restarted my computer for some reason, start back in to GNOME. And I was surprised with the default notification showed up. It replaced the GNOME notifications! I tried to: Reinstall gnome-shell. (autoremove and install) Reset desktop configuration. But it didn't work at all. Is there anything I can do to fix it? Plus: I got a double notification (osd + gnome notification showed up) when someone chatted me.

• Disable Alt for window move in gnome-shell

  - by artfulrobot

  There are lots of posts on this about Unity, this is about gnome-shell As with other posters, I use apps (Inkscape in particular) that uses Alt-Click and Alt-drag. Gnome-shell is grabbing this off me and thus disabling features in the application. I have tried using ccsm's Move plugin - you can turn this off and you still get Alt-drag window moving. using gconf editor to change /apps/metacity/general/mouse_button_modifier - this has no effect AFAICS. It's really hindering me. Otherwise I find gnome-shell a really productive environment.

• Gnome Shell opens as classic

  - by Joe Horgan

  I'm running 12.04 on a Gateway LT4004u netbook, and I installed Gnome3 using the apt-get commands in the terminal. When I rebooted and ran "Gnome Shell" it opened up classic mode. I thought that my cursor might have slipped the first time, but on multiple retries logging in under gnome shell would open the gnome classic desktop. I even uninstalled Gnome Shell and reinstalled it with software center, but I still have the same problem. I was wondering if this might be an issue with my graphics card? Any help would be much appreciated, thanks! -Joe

• Changing the priority of Gnome Shell

  - by user32655

  I want to give Gnome-Shell the highest priority, but I couldn't change the priority on the System Monitor, an error messeage says: Can't change priority's process with pid 2841 to -5. Access denied I tried the following commands: gksu gnome-system-monitor But I can't find Gnome-Shell on the processes list, so I tried "renice command", like this: sudo renice -15 2841 And finally got this problem, the Gnome-Shell's PID always changes, it's not the same PID numbers, so I have to change the priority every time I start up my system. Can anyone help me? Thanks.

• Customizing Gnome Shell in 11.10

  - by gentmatt

  Since Unity on my old MBP is not that snappy, I really want to change my GUI to Gnome Shell. However, I've really been struggeling with the customization of Gnome Shell. Can you help me with the following: Is is possible to have the dock on the screen all the time? Can I enable 'hot corners' for features like 'scaling' in compiz? Is there a ccsm-like GUI configuration tool? Can I enable wobbly windows in Gnome Shell? How do I change the shortcut for the WIN-KEY to start this 'Gnome-Mission-Control' (by that I mean this thing u see when going to the top left corner). Thank you.

• SHELL OR PERL QUESTION

  - by user150674

  I have a very large file, named 'ColCheckMe', tab-delimited, that you are asked to process. You are told that each line in 'ColCheckMe' has 7 columns, and that the values in the 5th column are integers. Using shell functions indicate how you would verify that these conditions were satisfied in 'ColCheckMe' K got this... nawk ‘ NF != 7 { Printf(“[%d] has invalid [%d] number of fileds\n”, FNR, NF) } $5 !~ /^[0-9]+$/ { Printf(“[%d] 5th field is invalid [%s]\n”, FNR, $5) }’ ColCheckMe Now, 2. In with the similar file, you are told that each value in column 1 is unique. How would I verify that? Also write a shell function that counts the number of occurrences of the word “SpecStr” in the file 'ColCheckMe' Any one can help in SHELL or everything including the first in PERL Scripting.

How to deal with that?

• Gnome Shell Blank edge until restart?

  - by jtaillon

  Since I installed Gnome Shell (which I much prefer over Unity), there has been a small annoyance appearing on the right side of my screen. As you can see in the picture below, there is a blank few pixels on the right side of the screen. It goes away if I reload gnome-shell ("r" command), but obviously, I'd prefer that this is not necessary. I'm not sure what exactly is causing this, but was hoping someone might be able to help. I'm running Ubuntu 11.10 on a Lenovo Thinkpad Edge E420s

• Bourne Script: Redirect success messages but NOT error messages

  - by sixtyfootersdude

  This command: keytool -import -file "$serverPath/$serverCer" -alias "$clientTrustedCerAlias" -keystore "$clientPath/$clientKeystore" -storepass "$serverPassword" -noprompt Will when it runs successfully outputs: Certificate was added to keystore I tried redirecting the stdard out with: keytool ... > /dev/null But it is still printing. It appears that the message is being output into standard error. Since when I do this it is not displayed: keytool ... > /dev/null 2>&1 However this is not what I am wanting to do. I would like error messages to be output normally but I do not want "success" messages to be output to the command line. Any ideas? Whatever happened to unix convention: "If it works do not output anything".

• Shell Script Sequencing with Rake

  - by Haseeb Khan

  Hi All, I am working on a rake utility and want to implement something mentioned below: There are some shell commands in a sequence in my Rake file. What I want is that the sequence should wait for the previous command to finish processing before it moves to the next one. sh "git commit -m \"#{args.commit_message}\"" do |ok, res| # Do some processing end sh "git push heroku master" So, in the above example what I want is that sh "git push heroku master" shouldn't be executed until the processing in the sh "git commit -m \"#{args.commit_message}\"" do |ok, res| # Do some processing end is completed. Also another nice to have would be that if I can store the output of the shell command in a Ruby variable so it can be used in further manipulation if required. Looking forward to a reply from the fellow community member shortly. Thanks in advance.

• Bourne Shell: Convert ~/Desktop to /users/me/Desktop

  - by sixtyfootersdude

  Incredably annoyed at the Java Keytool. So much so that I have created a new tag: "SunSuck". The keytool does not resolve impartial directories. Ie this works: keytool -keystore "/users/me/Desktop" ... This doesn't: keytool -keystore "~/Desktop" ... Is there something that I could call like this: keytool -keystore "$(<cmd> ~/Desktop)" ...

• Bourne: if statement testing exit status

  - by sixtyfootersdude

  What is the difference: if IsServerStarted ; then ... and if [ IsServerStarted -eq 0 ] ; then ... Seems to me that these two statements should be equivalent? Strangely the second statement is always true.

• Automatic exit from bash shell script on error

  - by radman

  Hi, I've been writing some shell script and I would find it useful if there was the ability to halt the execution of said shell script if any of the commands failed. See below for an example: #!/bin/bash cd some_dir ./configure --some-flags make make install So in this case if the script can't change to the indicated directory then it would certainly not want to do a ./configure afterward it fails. Now I'm well aware that I could have an if check for each command (which I think is a hopeless solution), but is there a global setting to make the script exit if one of the commands fails?

  my desktop CMOS battery is not working, therefore I have to set time and date each time my computer starts up. I want to create a shell script to automate the setting of date and time on my computer after each boot is complete. options that exist include: 1. buying a CMOS battery :- am considering this, but for the meantime a shell script will do. 2. using NTP to synchronize time and date with internet servers :- am not connected to the internet.

• Awesome-WM inside gnome-shell -> Get rid of top bar

  - by joe8

  I am using awesome-wm now, and was trying to get it working with gnome-shell. I have basically followed those steps: http://awesome.naquadah.org/wiki/Quickly_Setting_up_Awesome_with_Gnome#Ubuntu_11.10 But now I have two bars, one at the bottom and one at the top. Is there any way to get rid of one of those (preferring top bar). If that is not possible, is there a way to load the gnome-shell widgets in the top bar? Now it's only displaying the time. screen: Thanks ;)

• How do I fix gnome shell themes?

  - by Chris

  This is my fifth full format and install of Ubuntu in under a month. I finally have my Gnome 3 desktop working again, but again, the Gnome shell themes is not select-able. I have asked the question of how to fix this common issue before, but I have seen no positive resolution. Does anybody know of a simple fix? This is a common issue and I have seen hundreds of postings related to it, but other users only seem to get half-way answers also and it goes unresolved. Would it be advisable to completely purge Gnome desktop and reinstall? If so how would I do this? I cannot use any extensions if the shell is not working, so I am desperately seeking resolution for the issue. Thanks in advance.

• ATI graphics card, with gnome shell on Ubuntu 11.10, screen flickers

  - by bioShark

  After installing gnome shell, without any problem, after log in the fonts are missing and it looks like crap...nothing is readable. Don't want to make it a double post, because my issue is similar to the one from this question but for me the problems have not been solved properly. After running the commands from that post, and installing the latest AMD 11.10 driver, the Gnome shell display issues have been solved. But each time I move the mouse in the upper left corner, to bring up the applications...my entire screen flickers. Without the applications been displayed, everything looks fine. Hardware: ATI HD4870, Intel Q6600.

• Ubuntu 11.10 Gnome Shell new window focus problem

  - by grafthez

  I'm using gnome shell with new ubuntu for few days now and have experienced really annoying behaviour with new windows. Sometimes when I use another window and press e.g. Alt Ctrl T to open new terminal window, I don't get this window being brought to front. Instead I get notification at the bottom that "New terminal window is ready to use". The same is with Pidgin being integrated with gnome shell (via extension). Every time I get new message, window pops up but doesn't show. I need to either Alt Tab it or click the notification. Is there any way to have new windows being always brought to front, and remove those annoying "Window is ready" notifications?

• Only close button shows up in Google Chrome in GNOME Shell

  - by TreefrogInc

  After I installed the GNOME shell in Ubuntu, I decided that I didn't like having the "Close/Minimize/Maximize" buttons on the right, so I switched them over to the left using gconftool-2 --set "/apps/metacity/general/button_layout" --type string "close, minimize, maximize:" After resetting the shell, however, I found that with the GTK+ theme, only the close button shows up. Using system title bar and borders will make all the buttons appear, but I really want to use the theme because the system title bar makes the top bar too thick. Logging out and back in didn't fix it, and I tried reinstalling Chrome, but the problem persists.
