• How to modify the default position of desktop icons

  - by Hanynowsky

  Is it possible to modify the default desktop icons position so that icons move a little bit to right. If yes, how? As far as I know, there is no tweak for that in Nautilus. When I click "Organize Desktop by Name", the icons get aligned to the left of Desktop: that's fine, but they're too close to the launcher when it's in AUTO HIDE mode. So when Launcher is revealed, it comes over icons. Reproduce: Download some files from your browser or copy files/folders from a folder to the desktop, then these latter will be placed just like the screenshot. Their position is fine when the launcher is hidden, but when revealed, it hides a part of the icons. There is no problem when LAUNCHER AUTO-HIDE MODE is disabled. Thanks in advance.

• Frustrated with MythTV 0.26

  - by Mike

  I've been using MythTV for a while now. Until a hardware crash I had a 0.25 box running without problems. Had to get new hardware and am now in the process of setting up 0.26. Every time I pick a menu option, it hangs for 1 minute. Every time I try to start the backend, same thing. I pick a new theme in the frontend, but it never gets used. I try to test audio, but all I get is static (from the proper channels though). I've setup the storage groups in the backend and put a video in /storage/videos but the front end won't see it when I scan for changes. I make changes in the front end configuration and they don't get saved (or get lost randomly 2-3 reloads later). Obviously there is something I am doing catastrophically wrong, but I have no idea what. Are the storage groups not working yet? Maybe I need to delete all the storage group entries and just use the front end override to set the path? I'm currently using lvm across 3 hard disks, and this has worked well for me in the past. I'd like to use storage groups, but frankly I don't see them working yet at all - especially not for videos (which is what we watch 99% of the time). Anyone have any suggestions for me to try before I just call 0.26 bad names and wipe the system?

• Phonon - Audio Hardware Setup

  - by Michael

  Does anyone know what configuration file is modified when I change settings within this area of the system settings? I keep choosing my Logitech USB Headset as the soundard, and, when I hit apply, it accepts that change and all is good. However, as soon as I close the system settings window, it loses the setting, so I have to leave it open all the time. How can I make this setting permanent? Thanks for any assistance. I'm actually running Kubuntu 11.10.

• Convert each slide to PNG with LibreOffice Impress in terminal with excel graph

  - by Dean

  I need to convert each slide in a powerpoint presentation to a PNG with the command line. I have tried to convert it to a PDF then to individual PNGs but the images haven't exported properly. These images are graphs originally from Microsoft Excel. If I export it as a PNG from within LibreOffice the graph exports properly, but not if I convert it to a PDF first using unoconv or the export tool in LibreOffice Impress. Here is a couple of examples, in impress: As you can see the image works. But when this is exported to PDF it looks like: So whats going wrong? As if its directly exported to PNG in libreoffice it looks exactly as is in the presentation. Also if I convert it to the LibreOffice file format this also happens.

• Can not authenticate form system tools

  - by alfish

  Whenever I try to run a program from gnome, I get messages like Authenticated is required to run the Gparted Partition Editor The same goes for all programs that need root permission and I try to run from 'System tools' in my gnome-fallback. However the same user can become root in gnome terminal with no problem (I added the user to sudoers). I must mention that I've changed the user's password after OS install, so I think I need to update something but don't know what. I appreciate your hints.

• Why is this by passing the SUDO password?

  - by John Isaacks

  I have a bash script I am using to automate a SVN checkout. The contents of the file were: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ Then when I double click the file it would ask me what to do, I would click the button "Run In Terminal" and then a terminal would pop up and ask me for the SUDO password. I would enter it, the script would execute and the terminal would close. I wanted to give some sort of indication that the script ran successfully so I edited my file to look like: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ echo "Head revision has been pushed to live server" I expected the terminal to now stay open and tell me the message afterwards. To my surprise it now opens and immediately closes. The script does execute and I no longer have to put in the SUDO password. Is this right? I do not understand why this is happening, seems like a security issue.

  I wanted to create an option in the context menu to set the clicked picture to current desktop background (just like in Windows). I read the the nautilus action help but I couldn't figure it out.

• Evolution not downloading messages for offline use

  - by RandomX678

  Even though I've selected "Copy folder content locally for offline operation" on my inbox and "Automatically synchronize account locally" in my account options, Evolution still only downloads headers for my inbox. When I click an email, its downloaded from the server. I want all my emails to be available to read offline - As far as I know this should be possible, so is my configuration that's wrong, or is it a bug?

• switching users in byobu session

  - by JohnMerlino

  I launched a byobu session (tmux) and then tried to switch to a user called kommander "su - kommander", it immediately prompted me with: [Oh My Zsh] Would you like to check for updates? Type Y to update oh-my-zsh: Now I usually press "n" and everything is fine, but within the byobu session, when I press enter it just displays a "^M" character. I have no idea how to exit out if this prompt: [Oh My Zsh] Would you like to check for updates? Type Y to update oh-my-zsh: n^M

• Quickly Application making it run on startup

  - by unknownone

  I have a PyGtk application that I made using Quickly, and I would like to have it run on startup when installed. How would I go about doing this? I'm not sure if sticking the .desktop file in ~/.config/autostart/ would make it work or not. If that will fix it, I don't know how to add it to that folder since Quickly packages the project for you and has it's own installation script. Is it possible to modify what it does on installation? If possible, I would also like to add the program in the System Settings Personal tab, but I do not know how to do that. Thanks

• Low-res emacs24 icon in application switcher 12.10

  - by MTS

  I recently upgraded to Quantal, and also switched up to emacs24 from 23. Everything is great, except for one thing: the icon in the Application Switcher for emacs24 is a horrible, low-resolution eyesore. Compare the two side-by-side: I've seen a couple of questions addressing issues like this, but they're not quite the same. This one says that it is happening with all icons, but that's clearly not the case here. And this one seems more relevant, but it is talking about Gnome, not Unity. In the comments to the one answer for the second question, it says to look at the icons in /usr/share/icons to see if they are low-resolution, and if so to replace them with better ones. There's a ton of emacs icons, in fact. They are in various subfolders of /usr/share/icons/hicolor and they are in sizes ranging from 16x16 to 128x128, and also there are scaleable .svg versions of the icons too. I noticed that there are no 192x192 or 256x256 versions. But it seems like that shouldn't matter, since emacs23 also didn't have icons in those sizes. Any help would be much appreciated!

• Kubuntu 11.10: How to remove "Search and launch"

  - by user38489

  Is it possible to remove the "Search and launch" whateveritis from my "desktop"? I've actually tried both Desktop and Netbook modes, but it stays there in both of them. I'm not afraid of editing files in the ~/.kde dir, but I would be really disappointed if this is the only way to do it. [more details/rants] I was able to wipe out several things but I've ended up with a black window that's movable (Alt-click) but not removable. Beside being surprised by the performances, I find Kubuntu extremely unfriendly, and I can't find the logic behind the items of the interface. I've tried to search for documentation, but what I've found is not updated and doesn't include the Netbook interface.

• How to discriminate vertical from horizontal scroll on Kubuntu/KDE mouse action for switch Desktop

  - by sandroid

  Currently trying out KDE, and I'm a big user of multiple workspaces/desktops while I work. I've noticed that essentially, KDE isn't able (or doesn't bother?) to tell between my mouse's standard vertical scroll, and the left/right scroll that it has. Just FYI, my mouse has a pretty sensitive scroll wheel with no discernible "clicks" so I can easily make my desktop look like it's on crack. Here's what I'd like: vertical scroll does nothing when applied on desktop, but left/right scroll causes me to switch to previous/next desktop. Here's what happens now - per settings for Desktop Settings -- Mouse Actions: Whether I scroll up/down or if I click left/right, I switch desktops. Thanks for your help

• Evolution and thunderbird sharing same mail data?

  - by balki

  Hi, I have been using Evolution for a quite long and it has downloaded around 1.6GBs of mails from gmail. I want to try thunderbird but I dont want to re download everything again. Is that possible to have both clients sharing same data? I'll make sure I don't use both at the same time if that matters. I'll move to thunderbird fully if I'm happy with it. Problems I face with evolution is that I have to have the GUI running always if I want to get instant alerts and send mail immediately. Also it loads the messages slow and even after I move to the next mail, it slowly downloads all the linked images before moving on.

• How to add a printer in gnome-shell

  - by artfulrobot

  I'm using Gnome Shell (although I'm not sure whether the "Printers" app is part of that or just part of Gnome). I go to "Printers" from the overview, click the + button on the bottom left, choose network and then see a message "FirewallD is not running. Network printer detection needs services mdns, ipp, ipp-client and samba-client enabled on firewall.". It's not auto detected anything. There's an Address box and a Search by Address tickbox, but neither seem to do anything. I'm frustrated because I know all the details of the printer, but have nowhere to put them in. Automation is supposed to make things easier, no? For example I know the printer is at lpd://10.67.5.3/lp1 but I can't put this in anywhere. Is there a GUI that works, or have I misunderstood how to use it?

• how to uninstall sphinx server

  - by misterjinx

  I installed (from sources) yesterday sphinx server and didn't think of configuring it properly, so I left the default installation directory (/usr/local). Today I realized that it created all of it's directories inside that directory, instead of creating its own (as I wrongly thought). So today I started again the installation and specified explicitly the location where to install. After that I removed the previous directories from /usr/local that were created when the first installation was done (bin, etc, var). So I thought of giving it a test. I created the .conf file and wanted to run the indexer. But now, the indexer always tries to search the .conf file in the old location (obviously does not find anything) and when I specify where to find the .conf file it gives me errors for each of the configuration settings present. I know I did something wrong when I deleted manually those files and that's why I'm asking you if have any ideas how to correctly uninstall sphinx. Thank you.

• Resize images to specific height value in ImageMagick?

  - by Jason

  I've looked around for this, and can't find an easily implemented solution. Currently I'm working on an application that deals with panoramas. As they come out of the batch stitch process, the dimensions average 18000x4000. Using ImageMagick, how can I downscale those images to a specific height value while maintaining aspect ratio? According to the manual, the convert operation takes in both height and width to resize to while maintaining the same aspect ratio. What I'd like is to put in 600 and 1000 in my existing resize script function and have both a regular viewable image as well as a reduced size.
