• Dual monitor gnome-shell broke itself

  - by JXPheonix

  Ok, lets get this over with. I have a dual-monitor, ati setup on gnome-shell that was just fine until this morning. Then, this happened. Look closer... Whatever has happened to my ubuntu setup? My second monitor still works, entirely normally, with the exception that I cannot (obviously) access activities (as i am in gnome-fallback ). I do wish to resume my work... EDIT: By entirely normally, I mean I can move my mouse over it and have seperate windows on it and stuff. It's not mirroring. UPDATE: Unity works entirely normally.

• How can I make the text cursor in X Windows easier to see?

  - by skyblue

  The text cursor in X Windows is too thin for me to see easily. It would be great if I could make the text cursor wider so that it was more visible. I know how to change the size of the mouse cursor in X by going to System Preferences Appearance and customizing the Pointer so that it is larger. But I have not been able to find any setting that allows me to alter the appearance of the text cursor. So how can I make the text cursor easier to see?

• How do I improve my ability to manipulate code quickly, not wpm?

  - by Steve Moser

  I have seen several questions on here about touch typing and words per minute but not about improving ones ability to manipulate text using keyboard shortcuts, bindings etc. I have tried putting a cheat sheet of keyboard shortcuts next to my monitor but I can never incorporate them in my 'flow'. I have also tried the 'just use vi and don't touch the mouse' method but that only helps me with navigating code and not editing. I would prefer to use some application (or game) to learn text manipulation. But it looks like nothing like that exists (app idea?). I'm open to other suggestions too.

• How can i change focus when game locks it?

  - by GrizzLy

  I am playing wolfenstein:enemy territory, and if i play it in windowed mode, i can't change focus from game to something else (alt+tab doesnt work). EDIT1: As far as i could try, only ctrl+alt+Fx works (x is one number, for example F1 will switch to terminal). Could i somehow capture this kind of shortcut somewhere on X level and then send it to compiz to change focus (minimize currently focused window)? EDIT2: I found one other way, it works for Wolf:ET, it may help with other games too, if you turn on gameconsole (usually tilde key) game will release mouse lock (in windowed mode).

• Why is Thunderbird pegging a core at 100%?

  - by david6

  I have experienced 2-3 unexplained lockup over last 10 days. Today, I had a random lockup (no mouse, keyboard response, 100% CPU). But, when I finally switched (Ctrl-Alt-F1) to command line (it took several minutes) it told me that thunderbird-bin had locked a CPU. I ran this to resolve: pidof thunderbird-bin sudo kill #### However, after saving other work, I tried restarting Thunderbird. It went to 90%+ CPU, and within 20 seconds it locked again. Once I have more detail I will raise a bug (on Ubuntu Forums). Does anyone have any other suggestions, advice? UPDATE Thunderbird 13.0.1 is quite stable in safe mode. Still working to resolve ..

• What are the files in /dev/input/ and what they do?

  - by Pouya

  I'm fairly new to ubuntu and I've started to search around everywhere and check everything! Recently I saw these files at /dev/input/eventX, js0, mice, mouseX. By printing the output using "cat" I realized they are somehow responsible for mouse and keyboard input but the output had an strange character encoding (even for the keyboard). My questions are, what are these files and how can I interpret the data of these files? Are there any other places that I can access the input/output of my Ubuntu machine? And are there any ebooks, manual or something similar that I can check the duty and structure of ubuntu system files? (i.e. to find the answer of such question)

• will Unity have a keyboard shortcut for accessing the "Session Menu" that appears on the panel?

  - by Sam

  I noticed in screen shots of Unity the presence of the "Session Menu" indicator in the right corner of the top-panel. This menu drops down to offer Log Out, Hibernate, Restart, Shut Down, etc. I know the keyboard shortcuts are not complete yet. But are there plans to implement a shortcut for accessing this Session Menu (i.e., so users can log out, restart & shut down without having to use the mouse)? Further, will the shortcut allow navigation through the menu by just typing the first letter of the listed word (e.g., R for restart and S for shut down)?

• Issues with Dz77BH-55K Motherboard and i7 processor on 12.04

  - by Naveed

  I just built a computer with Intel's DZ77BH-55K motherboard with i7-3770 processor. On 12.04, 11.10, and 11.04 and Linux Mint 12, the computer has been really laggy. The graphics aren't working (choppy effects, bad resolution) and the keyboard and mouse inputs are even laggy and unreliable (skips keystrokes). I'm not sure what the problem is or what I can do to fix it. I tried sudo apt-get install mesa-utils but nothing changed. I've also messed around in the BIOS but no luck there either. Any ideas? Could it possibly be a hardware issue?

• 12.04 64 bit: Keybord not responding for about 20 seconds at startup/beginning of session

  - by Danilo

  I am running Ubuntu 12.04 64bit. When I get at the login screen and try to type the password for my user, I cannot type anything for about 20 seconds. After that, the keyboard starts responding and everything works fine. Mouse is responding normally as well as all buttons of the login interface (time/calendar, session selection (Unity/Unity 2D), etc.). What could be the reason for this behavior? How can I solve this temporary freeze of the keyboard so that I can type my password immediately without having to wait each time? Thanks for your time. EDIT: I tried auto login, but the problem is still there: the Desktop loads but even there, if I try to type something in the dash or anywhere else, I must wait about 20 seconds before I can actually start typing. Can the issue be related to some keyboard modules that get loaded little bit "too late"?

• Selecting Items in a GeoToolkit Driven Map

  - by Geertjan

  When you take a look at all the tools provided by GeoToolkit, you'll be quite impressed. For example, within the US map shown in yesterday's blog entry, you can drill down into individual states by selecting them via the mouse, as shown below: With that, the basis of a more complex application is laid, since all the map-related functionality is handed to you out of the box. The sample referred to yesterday has been updated, if you check it out and run it (assuming you've taken the additional steps mentioned yesterday), you'll see the above. http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/tutorials/geospatial/geotoolkit/MyGeospatialSystem

• How to disable mouseover popup icons on launcher?

  - by John

  If an application is open and its icon is contained in the launcher panel, moving the mouse over the launcher icon will cause a very annoying popup icon to appear, showing a small image of the open application. It is annoying because it lingers too long and covers other information. For example, it covers the menus that appear when I right-click on a launcher panel icon. How do I disable these mouseover popups? I don't necessarily want to disable the "text" mouseover popup, I only want to disable the image popups. Thanks. Ubuntu 12.04, new install.

• How do I run Conkeror in Emacs?

  - by Anake

  I have been using emacs for about 3 months, and have been amazed by how much improved my interactions with my computer are. I now use eshell rather than a separate terminal, and the last thing I still need to leave my emacs environment for is for my web browser. I have been reading up on Conkeror, and it seems almost ideal (emacs keybindings, no need to use the mouse etc.) but it runs in a separate window. If it could be run within emacs, it would mean that I would never really have to have interaction with the actual OS, which would be good for someone who is forced to rotate between linux, mac and windows (i.e. me). I understand that it couldn't be run from emacs in -nw mode, but would it be possible (or likely) that Conkeror could be setup to run within an emacs window? Note: - I've tried w3m and didn't really like it

• How To Create Custom Keyboard Shortcuts For Browser Actions and Extensions in Google Chrome

  - by Chris Hoffman

  Geeks love keyboard shortcuts – they can make you faster and more productive than clicking everything with your mouse. We’ve previously covered keyboard shortcuts for Chrome and other browsers, but you can assign your own custom keyboard shortcuts, too. Google Chrome includes a built-in way to assign custom keyboard shortcuts to your browser extensions. You can also use an extension created by a Google employee to create custom keyboard shortcuts for common browser actions – and less common ones.

• How to modify Dreamweaver's SpryMenuBar.js to send a msgbox on what menu was clicked?

  - by Mike

  I have a simple HTML webpage made in Dreamweaver with a SpryMenuBar. When I click on a menu item, I want to send a pop up message box that says which menu item was clicked. (This is not really my objective but once I can learn to hook into the spry java script with a mouse click listener I can try to do what I am really after.) The problem is for some reason I can't seem to get started with this seemingly simple task. Does anybody know how to revise the SpryMenuBar.js to make a msgbox showing the item that was clicked? For example if I click a menu that say's 'Contact us', I wan't to throw a message box that says "You pressed, Contact us". Note: My final objective is to actually call another function that changes text in the center of my page, depending on what menu item was clicked.

• viewing fbx files in windows via xna 4.0

  - by user17753

  I've made some models in Blender and exported them in Autodesk fbx format. I'm trying to view them using XNA 4.0 Refresh. Loading them isn't much an issue, but I'm not familiar enough with XNA 4.0 to, well basically I want to load in the model at say the origin (0,0,0) world coordinates, and then rotate and/or zoom the camera about the world coordinates origin as well so that I can test the model. Typically the mouse, and maybe some arrow keys for zooming/rotating the camera. Anyways, this seems like a simple task and I shouldn't have to re-invent this, isn't there a skeleton code somewhere for this kind of thing for XNA 4.0? I couldn't find a solid example for this on the web. I found a couple that seemed like they might work for xbox, but I'm trying to do this on windows only. Anyways, just looking to be pointed in the right direction on this one, thanks.

• Problems installing 13.10 inside VMWare Player 4

  - by Thomas S.

  In the past I had no problems installing Ubuntu 12.04 inside VMWare Player 4.0.4 on my Windows 7 Pro machine. Now I installed Ubuntu 13.10 and have a couple of problems: the default screensize (even during the installation) is gigantic I've told Ubuntu to automatically login - after reboot the gigantic screen occurs without showing anything, without doing anything on mouse clicks, Ctrl+Alt+Backspace does not work switching to console using Ctrl+Alt+F1...F6 works, but is incredible slow invoking 'sudo reboot now' does not succeed, it prints Killing all remining processes... [fail] Restoring resolver state... [ OK ] Will now switch to single-user mode root@ubuntu1310:~# invoking now 'shutdown now' will soon show the same error. What I need to do to get Ubuntu 13.10 up and running in VMWare Player?

• Effects of automated time tracking/monitoring [closed]

  - by user73937

  What are the effects of monitoring the developers' computer usage? (Which program they use - based on the title of the applications - and how much time in a day they use the keyboard and mouse.) Would it has any positive or negative effects on productivity, morale, motivation, etc? It will not have any direct impact on the developers' salary or their performance review it's just for curiosity. The developer and their manager will only see the results. Would it change anything if only the developer is allowed to see the results? The developer can disable the monitoring (for privacy) but it won't count as work time (in the monitoring program).

• Problems about responsiveness and keyboard/mousepad not working

  - by ChrisTheNoob

  So I installed Ubuntu 12.04, I'm very new at this and want to get into the world of Linux but have run into nothing but problems. I have an Acer Aspire 5553g. First off, my keyboard won't work. Second, my computer has more than enough of everything to run Ubuntu smoothly, but everything runs extremely slow. (You move the mouse and it gets there a few seconds later) It's to the point where I can't even use it and I really want to. I'm tired of Microsoft stuff and I've been looking at learning how to use Linux based operating systems for a while. Please send me some help to fix these issues and maybe some tips to help get me started. Thanks in advance chris

• Plug-in or framework recommendation for showing content preview fly-over in CMS

  - by Michael Huang

  The requirement is to have either front end plug-in or back end processor that generates the preview of contents (such as images, videos, PDF files, HTML pages) in a preview popup when user mouse hovers the content. I did some research on this, seems that there are assorted jquery plugins for each type of files, but what we are looking for is a framework that handles all types of file previews. Ideally, we want to generate preview images on the backend, considering the cost of retrieving content on front end. I did find some open source or proprietary CMS that provides this feature, but usually they are shipped as one suite and the API for file preview might not be open. Is there any java or jquery framework that handles file preview? Thanks a lot

• Lubuntu 13.10 selected LX games desktop now can't login

  - by user111667

  I logged out of my normal desktop and selected LX games from the dropdown list and logged back in. This led me to a black screen and now I can't see the login screen in order to change back to my normal desktop. On startup the machine boots normally, the lubuntu splash screen shows up, then it goes to a black screen with nothing on it - not even a mouse cursor. I can bring up a terminal using ctrl+alt+F2. Is there a way via terminal to change my desktop environment back to its previous state? Or alternatively, is there a file I can edit where my preferred desktop is stored? (The machine is dual-booted so I can access the Lubuntu files from LXLE which is installed on a second partition). The machine in question is a Toshiba A200 laptop.
