• Print screen key can no longer select a region to capture

  - by Steven Sproat

  After upgrading from 11.04 to 11.10, I've noticed that the "Take Screenshot" application used to be launched when I'd hit print screen. Now it automatically captures the entire screen. In 11.04 it would pop up the "take screenshot" application which allows me to capture a rectangular region of the screen. Can this be reverted? I never want to capture the whole screen, only portions of it, which means manually cropping out that section in GIMP with this changed behaviour. Cheers.

• Create new terminal commands

  - by sleort

  I recently installed eclipse the manual way. Extracting the file, setting up eclipse.desktop etc. It all works flawlessly. I also know it is possible to install eclipsee using sudo apt-get install eclipse-platform. If I use this method I can use the command eclipse in the terminal, and the program will start. Now the manual way I used does not enable the eclipse-command in the terminal. Instead if I use eclipse-command it asks me to install eclipse from the Softwarecenter (sudo apt-get install eclipse-platform). I wondered if there was some way of setting up a command like this to start eclipse? If so, can I do it for other programs like Apache-Maven mvn-command? I don't want to use "aliases" because I cannot setup and eclipse alias, when "eclipse" is listed in the apt repository. It seems as if only if I install the eclipse from apt-get install I can start eclipse from a single command in the terminal. I appreciate any help, and thanks in advance!

• How to restart Gnome Shell after a crash short of killing X?

  - by wintercorn

  How can I restart Gnome Shell after a crash? Alt+F2 and restart won't work as the prompt crashed with the shell. Since windows focus is gone along with the shell as well, I can't type gnome-shell --replace in a terminal, either. The Ctr+Alt+F1 command line can't open the X display. So I'm left with killing X, thus loosing all open applications. Is there a keyboard shortcut for restarting Gnome Shell?

• 12.04 Dell GX260 resolution for 82845G/GL will not go greater than 1024x768

  - by Steve M

  I am a newbie to Linux and have installed 12.04 on to an old Dell GX260, I was hoping that I could slowly extract myself from Microsoft - but unless I can fix this simplest of problems I am thinking that this version of Linux is not ready for me yet!! I have read various posts but none seem to match, I believe the driver is installed, but under displays the maximum allowed in the drop down box is 1024x768 (4:3) display is unknown and detect displays does nothing. I have loaded all updates available but still no fix. xrandr shows: VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 xrandr --addmode VGA1 1360x768 cannot find mode "1360x768" anything above 1024x768 can not be found, but then I could be doing this out of step!!

• Dual boot: Linux Grub loader does not show windows

  - by user292099

  my computer previously only had windows installed on it. Recently I decided to try Linux and opted for a dual boot so I installed Linux Mint 17 Cinnamon 64-bit on a separate hard drive within my computer. After installation my computer would directly boot to Linux upon start up and did not even show a grub screen. Using the boot-repair I was finally able to make the Grub loader show a boot list upon start up, but the Windows partition is not there. The boot-info summary is found on this link. http://paste2.org/9pIGZtDv Any help would be great Motherboard: Gigabyte z77 ud5h OS: Linux Mint 17 Cinnamon 64-bit & Windows 8.1 64-bit

• Why did this command ":(){ :|: & };:" make my system lag so bad I had to reboot?

  - by blade19899

  Danger! Do not run this command to "test" it unless you are prepared for a crash and/or force-rebooting your system I was in my Virtualbox running 12.04 trying to compile an app, and while waiting I happened to chance upon a forum where a comment said: Try :(){ :|: & };: Fun, too, and doesn't need root. Without thinking I ran it in my gnome-terminal it made my 12.04 virtualbox lag so badly I had to shut it down. My question is what does this command do? :(){ :|: & };:

• How do I stop banshee remembering what's been played?

  - by dunderhead

  How can I prevent Banshee from remembering what files I have played? I really hate the way it keeps surprising me by automatically playing, after the current track, the previous file it had played. I really HATE that. I was just listening to a beautiful piece of music and in a nice mood when Banshee, without asking me, immediately afterwards, started playing a really annoying answerphone message from earlier. My solution so far is to manually delete all files in the playlist, but obviously that's not a long term solution. I cannot find an option anywhere that says "Do not remember my history" (Did I mention I hate the way Banshee plays my files without asking me?)

• Two problems, both with either lock or suspend.

  - by user199208

  I recently did two things that may be the cause of either of them. 1) I started using a second screen 2) I installed xscreensaver instead of the stock, power saving option. My first question is about suspend: every time I wake from suspend, networking is disabled. While I've seen multiple posts about that on here, it didn't start happening until recently. Second, lock seems to be disabled now. Are both of these problems a bug, or was this caused by the second screen or maybe xscreensaver?

• How do I create the "Gnome-Desktop-Item-Edit" program's launch icon with root privileges and more?

  - by GanZ

  I personally dont prefer running commands in terminal to achieve a task and prefer apps to execute the job. Creating launcher for apps is one such command where I prefer the gnome-desktop-item-edit application for creating launchers. If the gnome package is installed, just searching "create launcher" opens the app. But, it doesnt serve any purpose, because for starters the application cannot create launchers for various apps without root permission and the location where the apps have to be created. Usually the launcher apps with root permission can be created at /usr/share/applications and without root permission at /.local/share/applications. I dont prefer the latter location as it is vulnerable to deletion. Hence, in order to create the launchers through gnome with root, everytime I am forced to open this through terminal using the below command! $ sudo gnome-desktop-item-edit ~/.local/share/applications --create-new I dont want to open terminal everytime I want to create an application launcher on unity! I am able to lock the "Create Launcher" App in the Launcher, but not with root privileges So I want to be able to create the "Create Launcher" app shortcut on unity with default root privileges and for the app to create the launchers at usr/share/applications by default! Please help! P.S. I dont have enough rep points to add screenshots to help with the question!

• dun goofed the files in /usr/lib/x86_64-linux-gnu/

  - by tipu

  there was some weird package issue with (in my limited understanding) 32/64 bit libraries, so i went around making symlinks to the file my lamp installation expected to the ones that actually existed. i did this for a # of files in here: /usr/lib/x86_64-linux-gnu/ however php still ended up not working (separate issue) and now i believe i have a screwed up lib directory. is there a way to revert those library files?

• Compiz features stopped working when an external monitor is attached

  - by adjfac

  Running 12.04 on a thinkpad T520 with nVidia NVIDIA Quadro NVS 4200M graphics. Just updated to the lasted nvidia 310 driver. Everything works great. However, as soon as I attached an external monitor using nvidia twinview, compiz features such as scale (moves all the active windows in one page) stopped working, as well as alt-tab to list all opened programs. Any ideas how i can fix this? never had this problem with 11.04. I can post my xorg.conf if that's of use to you. Thanks much! edit 1: I am using gnome3 classic edit 2: alt-tab works -- compiz application switcher (by default for gnome3 / unity) will crash gnome-classic, by changing to "static application switcher" in compiz seemed to solve the problem, but the scale still does not work when an external monitor is attached.

• True column-mode (block-selection and editing) text editor solution?

  - by tamale

  In windows, I used to use a text editor called crimson editor which featured the best column-mode editing support I have yet to use. When enabled via a simple Alt-C shortcut, selections could be made with the mouse or cursor keys and they would be visual blocks rather than wrapped-lines. These selections could be deleted, moved, copied, pasted, and all of the operations just made sense. You could also just start typing, and you'd get a column of the characters as you're typing. There are multiple ways of getting parts of the these features working separately discussed on this forum thread, but no one has yet to provide a solution that provides this all-encompassing and easy-to-use method. If someone could point me to a gedit plugin where this work is actively being pursued, perhaps I could help with the coding myself. If someone is aware of a text editor that already provides this full functionality, I'd appreciate the info. Running crimson editor through wine and the close-but-not-quite multi-edit plugin for gedit are the temporary solutions I'm 'getting by with' for the time being.

• Upgraded from 10.04 to 12.04, how can I make Thunderbird marks the indicators envelope blue?

  - by josvazg

  Upgraded from 10.04 to 12.04 now I don't have notifications on incoming email to Thunderbird on the indicator bar, neither when thunderbird is running nor when it's not. None of the other similar questions answers have helped me. Still no blue envelope. I DO get a notification when the email comes as a temporary OSD, ut the envelope in the indicators menu does not get blue and there is no line for received email under "Mail" althougth it is working for Google Mail.

• Change spacing of icons in Indicator Applet Complete, preferably by editing a config file?

  - by PeaTearGriffin

  Changing icon spacing within Application Indicator Complete. If at all possible, I'd like to space them with about 1-3px between each one. https://launchpad.net/indicator-applet [Website] I'm using 12.04, and in GNOME Classic (No Effects). I'm working from a netbook (1024x600), and am trying to fit everything into one panel for the sake of screen conservation. Ironically, my netbook is often without reliable net access, and so a way to simply edit a config file or the like would be ideal, as opposed to downloading patches, modified packages, etc., but anything would be helpful. Even pointing me in the direction of how to start rebuilding the indicator to meet my needs (if need-be) would be welcome. Does anyone know of a method that would serve my purpose? EDIT: I've downloaded v0.4.93 from the site mentioned above, and took a look inside the archive. Couldn't find anything clearly alluding to object placement/size and such. Maybe just a pointer on where to find those params would do? EDIT 2: Some more info on my WM/DE: I'm pretty sure GNOME classic is gtk2 not gtk3, and equally sure my windows manager is metacity, as opposed to compiz. "equally sure" meaning i could be horribly wrong, but when I edit the metacity css file for my theme (which ive switched to "Adawaita"), it takes effect after logout/login. My inability to modify the spacing persists. Im gonna see if i can contact someone involved in its dev to get their input, will post results here if fruitful.

• Lubuntu 12.10: Icon Display Problems

  - by SlcBullseye

  First off, I would like to let you know that I am new to Linux. I finally decided to give it a try and my first project was installing Lubuntu on an old PC and using it for a media server for my PS3. So, one thing that I noticed right away is that my icons for applications, files, folders, etc...are not visible. If I move my mouse over the name of the application or file (It only works if I move the mouse up from the bottom of the name) then the icon will appear, but if I move my mouse back over any other place on the file the icon will disappear again. Also, if I open a folder sometimes an icon or two will be displayed but the rest won't, and like I said before if I move my mouse over the top of the application or file the icon will disappear. Is there any way to fix this? Is this normal? Or could it be a problem with my hardware? I never had this issue when I was running the last OS (Windows XP). Any help would be greatly appreciated. Remember, I am new to Linux so a thorough explanation would be helpful. Also, if there are any tips, tricks, references, or recommendations any of you have to help me jump in and become more familiar with using Linux that would be great! I'm very interested in taking advantage of the power Linux has. Currently I am studying computer programming so maybe one day I will be able to develop my own Linux distribution.

• How secure is KeePassX?

  - by Uli

  I have hundreds of passwords, since I use a different random one for each website/service. They are all generated & stored with KeePassX, which can be synced to different computers and my android phone via dropbox (or ubuntuone). I know the database of KeePassX is secure (at least with a good passphrase). But what about when I am copying the password into the clipboard (where it is stored for 5 seconds)? Can any program running in user-space access the clipboard and store the password? If so, how big of a security risk is this?

• Installing multi-boot Linux system

  - by user94924

  I have a dual (XP/Linux) boot Compaq Presario S4500UK with a couple of spare partitions on the boot drive which I want to use for testing different Linux distros/configs before installing them on "live" machines. I tried this with Oneiric which worked fine until I came to uninstalling the test system. Fortunately Oneiric uses Grub2 and so redirecting the bootloader to work from the original Linux partition was a piece of cake - if a bit annoying. I now need to do some tests on Hardy and DSL (Damned Small Linux), neither of which use Grub2. Question: Is it possible to install a test operating system without adding/replacing the bootloader (ie so I can still use Grub2 from the original partition with its nice interface and recovery facilities)? Is there another way of uninstalling/decommisioning a test OS which doesn't trash the boot loader? (The only way I know to do this is by deleting/reformatting the partition which takes with it the bootloader which is in that partition). Any help would be much appreciated. Tks jg1

• Drive reporting incorrect free space

  - by Oli

  So I swapped my shiny SATA SSD for an even shinier PCI-E SSD. I run my core OS on the SSD because it's silly-fast. I did this on my old SSD so I created a new EXT4 partition and then just dded the data across (sorry I don't know the exact command I ran anymore) and after reinstalling grub, I booted onto the PCI-E SSD. At first glance everything had worked perfectly and things were running faster than ever. But then I noticed the free disk space on the new, larger drive: it was almost exactly the same as it was on the other disk... A disk that was half its size. So it looks as if I've copied the files across incorrectly and it's copied some of the filesystem metadata along with it. Tools like du and Disk Usage Analyzer come back with the correct figures. Things that look at the partition (and not the files) seem to think the drive is 120GB I've been using this drive for a week now so it's way out of sync with the old SSD so dumping the data and starting again isn't a job that fills me with joy but two questions: Is there a way to fix my filesystem so it knows what it's really on about? fsck e2fsck and badblocks all seem to be able to scan it without finding a problem with it. If I do plug my old SSD back in, copy the data off my PCI-E on to it and then copy it back onto a fresh filesystem (eg juggle the data around), what's the best way of doing that? I obviously want to keep all the permissions and softlinks where they are.

• Keeping local folders synchronized

  - by Earthling

  After repeatedly losing data on encrypted drives due to some trivial combination of software and hardware failure, I would like to know if there is a simple tool that keeps local folders synchronized. Like a local "cloud" service that runs on one computer and synchronizes any changes in one folder to the other folder as soon as both folders are available. That way I can keep a copy of the most important files on a different hard-drive.

• Why is text on my TV monitor all grainy?

  - by searchfgold6789

  I have successfully installed the Catalyst drivers and hooked up my 1080p TV to the Radeon HD 5750's HDMI port and now it is working. There only seems to be one issue - most images appear OK, at least to my eyes, but text is grainy and difficult to read (not sure how well it can be seen in the picture): It works fine with a smaller screen, and hopefully you can see it with the new pictures which are only slightly better, but images are rendered a little funny too. Changing antialiasing does nothing and changing the refresh rate only makes a slight change if any. The small monitor I have works fine. Smaller resolutions such as 1024x768 look OK but are the wrong aspect ratio. I have tried renaming the input mode on the TV to "PC", and that helped... a little bit. Also, I tried a different PC with the same result. Messing around extensively with the ATI Catalyst Control Center also did not help. I am wondering if there is anything else I can try to increase the quality so it is more usable.
