• How to adjust DPI in 14.04

  - by jake

  I asked about fixing DPI in 12.04. The 14.04 release notes list "Support for High-DPI screens and desktop scaling." Post upgrade, it seems that nothing has changed. Similar symptoms from my previous post persist: The 1" square here is closer to 1/2" Despite the line xserver-command=X -dpi 170 in /etc/lightdm/lightdm.conf, xdpyinfo reports 96x96 dpi I did find that I was able to use the "Scale for menu and title bars" slider in System SettingsDisplays to fix title bar text size instead of setting org.gnome.desktop.interface text-scaling-factor as described here. The last post also mentions that in Gnome 3, DPI is hard coded to 96. Is this a limitation in 14.04? (I am somewhat ignorant to the distinction between Gnome and Unity) Can I do anything to properly set my DPI?

• Technique to Display Multiple Browser Windows Tiled at Same time?

  - by Kendor

  I have a separate monitor that I use for Toodledo (a web-based task managment app), in which I like to display various views (Next Action Status, Waiting Status, Planning Status, and Overdue Due-Date items). I've been playing around with some add-ons on Firefox that allow you to split the browser, but they are cumbersome. I'm now trying Chrome, and opening 4 different browser windows that I've tiled on the screen in quadrants (I use the Compiz grid applet for this). This is not ideal as each browser replicates the URL bar and the tab, and I don't have opening ths windows automated upon restart. Chrome is great in managing screen real estate, but this is not ideal. In Firefox I tried various extension to hide interface elements, but it was very clunky... Am wondering whether anyyone has tried to do similar with TD, and how they achieved what I'm going after? Am wondering whether someone has a good technique for accomplishing what I'm looking for?

• How do I stop that launcher from popping up when mouse goes to the left edge?

  - by Michael

  This is what it says on the help.ubuntu.com website, but when i go to system settings, it does not have a Launcher & Menus option. I wish I could revert back to the old Ubuntu, I hate this launcher. Does any know a fix plz? "Stop the launcher from showing when I point to the left side of the screen The launcher unhides when you move your mouse or touchpad pointer to the left side of the screen. If you prefer, you can tell Unity to only show the launcher when you click the top left Ubuntu button instead. Click the icon at the very right of the top bar and select System Settings. In the Personal section, click Launcher & Menus. Choose Touches the top left corner of the screen"

• Where do my programs get installed?

  - by Micah

  Coming from windows I'm used to having everything installed in c:\program files\company\product. On Ubuntu I'm totally stumped. It seems like everything I install winds up somewhere different. Somethings are in /bin some in /home/myuser and others in /etc or /usr. I can't seem to figure this out. In particular I'm trying to find where they're located so I can either setup shortcuts on the task bar or associate them with other programs (like my greasemonkey editor) but I'm not having any luck.

• SEO: disallowing Google from indexing forms in iframes or not?

  - by Marco Demaio

  I usually place forms in iframes (i.e. order form, request assistance form, contact forms, ect.). Just the forms, I never place other contents or pages in iframes. From a SEO point of view, would you exclude forms from being indexed/crawled by Google or not? I mean my forms hardly ever contains keyword/keyphrases, moreover I obviously place empty title/meta description tags in pages shown in iframe to display forms, cause those titles are never displaied in browser title bar. So I'm wondering what's the point of letting Google index them? Moreover I think these form pages might suck out PR from all other pages that are more valuable for SEO. If your answer is "yes I would exclude them form indexing" would you simply use robots.txt to exclude them? Thanks!

• Why can't the Unity panel be hidden?

  - by newboldrob

  I am a light Linux user. I have Natty installed on my netbook and used to have it dual-booted on my Windows 7 PC. After a total refresh of my notebook off came Ubuntu and I'm back to basics over there. But HERE (I'm running Natty on a HP-Mini) I've decided to poke around a bit to get the best user experience on this little thing. I really like the Unity interface but really hate the static Unity Panel. I have no clue why it's even necessary to be on globally. After all, in the classic interface, both panels can autohide or get filed aside with buttons on either side of the bar. On a 10" screen, real estate is at a premium. What intrinsic purpose does the static unity panel hold for the OS? There has to be a great reason for this thing to HAVE to be here. It ONLY goes away in fullscreen apps and I can't use everything fullscreen Why can the unity panel not be hidden?

Once the site has loaded, click the Pin to Start button on right side of the bar at the bottom. HTG Explains: Is UPnP a Security Risk?

• What's the right terminology for Unity's UI elements?

  - by Bou

  Hi, I've sent a few mails to the Ayatana mailing list regarding some UI suggestions for Unity, but I'm afraid I keep confusing the right terms for the UI element, so I would like to have some clarification. Is the bar at the top called "panel"? Does the Ubuntu logo at the top left corner have a name? Is the left sidebar called "dock"? Are the coloured tiles with app icons on them called "launchers"? Is the purple tile called "workspace switcher"? Are the fullscreen things that appear when you click the Ubuntu logo, the Places tile or the Apps tile, called "dash"? Do they all have the same name?

• Issue with dynamic Quicklist in Unity

  - by costales

  I would like to add a Quicklist to Gufw app, but it isn't working. The code is here (you can install reading the INSTALL file): http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/files/3 I added lines 52-54 to the view (a simple example) from the official API web: http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/view/head:/gufw/view/gufw.py https://wiki.ubuntu.com/Unity/LauncherAPI self.launcher = Unity.LauncherEntry.get_for_desktop_id ("gufw.desktop") self.launcher.set_property("progress", 0.42) self.launcher.set_property("progress_visible", True) But nothing happen. But if I run this file with Gufw running: http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/view/head:/gufw/test_launcher.py $ python test_launcher.py The progress bar appears! :/ I don't know what am I missing? :P Any idea? Thanks in advance! The environment is Ubuntu 13.04.

• Radeon HD5670 hangs after login

  - by pKaresz

  Thanks in advance for your advices. I installed, Ubuntu 12.04 today, on my PC with a Radeon hd5670 graphics card. The first error I encountered, (just like the first time Unity came out - after witch I waited to try Ubuntu again until now) is, that it hanged after login at the desktop wallpaper, with only the mouse cursor. Well actually the first problem was with the live CD, but I managed to install it, using the install now, not the try now. Live CD has the same problem, as after install. So, after installing and getting the error, I searched of course before asking this:) I found this: Ubuntu hangs at purple screen The accepted answer there helped me to get to this. (note, that the below picture is a screen taken from a working desktop, and then erased the parts that don't show on mine.) Note that there is nothing at the top except the brown bar. No shutdown button, no nothing. The system hangs, I can't click on anything, I can only wiggle around with my mouse XD

• Unity won't load in Ubuntu 12.10

  - by Nigel

  I just upgraded Ubuntu last night to 12.10 from 12.04. When I rebooted like it asked, everything seemed fine, except one of my monitors had a white screen, and I could not use it. After some tweaking in the AMD Catalyst center, I got it to work, but now Unity wont load, and the bar up top wont load either. I am in suspicion that it a problem with Compiz, but might be completely wrong. Any tips on getting this to work? I am also kind of new at Linux, but I could open a terminal and get Opera open for web browsing, but it is really choppy and slow.

• Unity launcher full - Need more icons

  - by Martin Wildam

  I have already reduced the Unity launcher icons to 32 but still the space is exhausted already with my most-used programs. Basically I have to scroll often in the unity launcher bar with is annoying. So far (Ubuntu 10.04) I had those icons as mini ones in the top panel (smaller icons and wider space) where they could fit all. I was thinking already of sub-launchers or something the like but could not find something like the drawer was in Gnome 2. I am using Ubuntu at home and in the office. I am a consultant and need a lot of stuff on a regular basis. To put links at the desktop does not make sense because of the many windows that I usually have open there is hardly ever a piece of the desktop looking through. How do you - power users get keep most-used programs at reach (and I mean <= 2 clicks away)?

• How to reset Compiz/Unity to defaults?

  - by Stramato

  I tried to activate some compiz effect via ccsm (I think wobbly windows) and compiz crashed and froze up the screen. So I used the Control+Alt+Backspace keystroke to force logout. Then I logged back in. Unity wasn't there, just a (non-unity) panel at the top with file, edit, and the like. I was able to pull up a terminal and launch ccsm, only to find almost all settings wiped out. I turned everything back on that I thought should be on, but I don't know if I got everything. Also, now whenever I open up a non-maximized window, it opens up in the top left corner with the title bar behind the unity panel. So what I need is a list of everything that needs to be on in ccsm, and a way to get windows to NOT open in the corner, preferably without having to reset unity or compiz.

• Are there any tweaks for fixing the appearance of Eclipse Juno on ubuntu?

  - by agnul

  As we have previously established ;-) running Eclipse on ubuntu is a bit disappointing on the UI side. Things are even worse now that Juno is out. Are there any tweaks specific to Gtk3 and Juno that help make things better? The new UI maybe needs some getting used to, but I'm not convinced. Padding got much worse with all the extra (useless?) space between panes. The gradient on the toolbar looks ugly, the quick search looks like it needs some more polish, the buttons to switch perspectives maybe would look nicer without the quick search bar, tabs are waaay to big. Not sure the color scheme has been fixed since I'm running a modified theme for the sake of old 3.7 (the infamous white on black tooltips)

• Aptana Studio 3 does not start up in Ubuntu 12.10

  - by Agent47DarkSoul

  I followed the instructions provided here to install Aptana Studio 3 in my Ubuntu 12.10. I have completed all the steps with out any problems. When I click the Aptana icon in my Unity bar nothing happens. No error pops up! I gave permission on the sh file and on the directory (/opt/Aptana_Studio_3) but still same problem. If I try executing the sh file in the /opt/Aptana_Studio_3 folder, it says "Syntax error: "(" unexpected Aptana". Also I cannot execute the Aptana binary file directly. I have been trying to solve the problem for a while now. Any help would be much appreciated. EDIT: I have Oracle Java 7 installed. I have read some post about backwards compatibility problem with Java 6 but dont know whether that's the issue. I will edit the question if I find something new.

• Using IE 9 as my primary browser

  - by Robert May

  With the release of Internet Explorer 9 RC the browser looks to be in a usable state.  So far, my experience has been positive. However, one area where I am having problems is when people are using the jQueryUI library.  Versions older than 1.8 cause IE 9.0 to be unable to drag and drop.  This is a real pain, especially at sites like Agile Zen, where dragging and dropping is a primary bit of functionality. Now that IE 9 is a release candidate, we’ll see how quickly these things improve.  I expect things to be rough, but so far, I’m really liking IE 9.  There’s more real estate than Chrome (it’s the tabs inline with the address bar) and its faster than Chrome 9.0 and FF 3.6.8 (as tested on my own machine). The biggest drawback so far is that because IE has been so badly behaved in the past, sites expect it to be badly behaved now, which is breaking things now. Technorati Tags: Internet Explorer

• Webm videos converted with avconv not working properly

  - by user285943

  I'm converting mp4 videos to webm with the following command: avconv -i INPUT.mp4 -c:v libvpx -qmin 10 -qmax 42 -maxrate 500k -bufsize 1000k -threads 2 -c:a libvorbis OUTPUT.webm Am I doing something wrong? Should I use all of these parameters? I just want to make the videos compatible with all the browsers/devices. The videos are not working on Firefox on most devices and on Chrome in a specific Android device that I have. EDIT: When i play the embeded videos on firefox, on any android device, it goes straight to the end and doesn't play. It only plays if i click in the progress bar. If i open the videos on firefox without embedding them in a html page, they seem to have a bigger width box outside then, while the video is inside it. I uploaded a video that i converted. Try it in firefox: https://mega.co.nz/#!cg9FVZJD!CpC6X3NXH8rAVdBiS9ZqqwyITdyPb_qkKAKsvQXRpzI This is a comparison between the videos, after and before the conversion: ![Image here]: http://i.imgur.com/V2FijCQ.jpg

• Accessing managers from game entities/components

  - by Boreal

  I'm designing an entity-component engine in C# right now, and all components need to have access to the global event manager, which sends off inter-entity events (every entity also has a local event manager). I'd like to be able to simply call functions like this: GlobalEventManager.Publish("Foo", new EventData()); GlobalEventManager.Subscribe("Bar", OnBarEvent); without having to do this: class HealthComponent { private EventManager globalEventManager; public HealthComponent(EventManager gEM) { globalEventManager = gEM; } } // later on... EventManager globalEventManager = new EventManager(); Entity playerEntity = new Entity(); playerEntity.AddComponent(new HealthComponent(globalEventManager)); How can I accomplish this? EDIT: I solved it by creating a singleton called GlobalEventManager. It derives from the local EventManager class and I use it like this: GlobalEventManager.Instance.Publish("Foo", new EventData());

• Pronunciation in programming?

  How do you correctly or erroneously pronounce programming terms? Any that you find need strict correction or history into the early CS culture? Programming char = "tchar" not care? ! = bang not exclamation? # = pound not hash? Exception #! = shebang * = splat not star? regex = "rej ex" not "regg ex"? sql = "s q l" not "sequel" (already answered, just i.e.) Unixen | = pipe not vertical bar? bin = bin as in pin , not as in binary? lib = lib as in library , not as in liberate? etc = "ett see" , not "e t c" (as in /etc and not "&c") Annoyance / = slash not backslash LaTeX = "laytek" not "lay teks"

• Windows Phone 8 detected as mass storage

  - by legends2k

  From version 8 onwards Windows Phone supports MTP (media transfer protocol) to transfer audio and I thought I could use Rhythmbox to upload music onto my device. Thing is Rhythmbox doesn't display the device under Devices pane (there's no Device pane for that matter). I searched other questions here and tried out installing mtp-tools, mtpfs and also tried gMTP, which doesn't seem to detect the device as a portable player. I see that the device's icon looks like a Camera in dash bar and when I see the address location, it shows gphoto2://[usb:002,013]/, which makes me doubt that it's detected as a camera or as a mass storage device. /.gvfs/gphoto2 mount on usb%3A002,003 is where the actual mount is. What do I do to fix this? I tried creating .is_audio_player too.

• Unable to show correctly symbolic icons with appindicator

  - by user1502508

  I'm creating an app under Ubuntu 12.04 and using libappindicator and Vala. I want to use a symbolic icon, to ensure that the colors are adapted to the background in the status bar. Unfortunately, I'm unable to make it work. I installed my icons (which uses the BEBEBE key color) and they are shown, but the color is BEBEBE, not white or black like the other icons. I also tried to put an icon that I was sure to be symbolic (audio-volume-high-symbolic) but, again, it's shown with the original colors, instead of them being replaced by the current FG color. I used both set_icon and set_icon_full methods, but none of them worked :(

• Terminal shows menu in panel but window is missing

  - by Lai Yu-Hsuan

  I upgraded from 10.10. Then everything worked well except very important one -- my terminal. I try to open my terminal, but no any window popup. I press alt+tab and the windows switcher appears in which there is the terminal. I switch to it, however, nothing happens. I can see the word terminal in my top bar. When I move cursor on it I see the file edit view and so on. But they are useless unless I can find my terminal window. I have no problem with chrome, firefox, eclipse, ubuntu software center, pidgin and many more applications. But without terminal, I'm using a disabled linux.
