• What Language is unity written in?

  - by John

  What Language is Unity written in? Also, where can i get its source code? I have an idea for a windowing enviroment or shell (dont know what to call it). What i want to do is teach myself to create it. i like some of several ideas i have seen, but i want to redo all of them, also the concept of how a desktop works. I figured learning the language Unity is written in, and studying Unity and Gnomes code would be a good start. i am on Ubuntu 12.04 acer aspire 5920 3 gb ram 160 gb hard drive

• 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.

• Pppoe wireless connection, Ubuntu 12.4

  - by Barbara

  I recently bought a new computer (Asus 1015 cx) with Ubuntu (12.4) as preinstalled system. My problem is with the internet. The computer connects just fine to the free wifi we have at home, but in college, we have a little bit different system. There is wifi, but it is not free - everyone receives a user name and a password. I cant manage to estabilish this Pppoe connection - the computer "sees" where can it connect, but I dont know where to write my username and password. It is not the DSL connection, what I have already tried. Can you help me?

• Ubuntu gets slower by the day

  - by Doug

  Ive noticed that Ubuntu has been getting slower and slower to boot, launch programs, etc. I installed 12.04 about 4 months ago,now 12.10, running on a quad-core Q8300 Intel, 4GB Ram, and an 80GB WD IDE drive. For some reason (ever since 11.04), Ive noticed after installation, the speed is good. The longer I have the OS installed, every bootup gets slower and slower, launching programs get slower, frame rates change radically(onboard GF9400 gets anywhere from 60fps down to 12 in worst cases). I would think maybe the HD is the issue, however I installed 11.10 on a 160GB SATA, and the same thing occurred. Looking at system resources, I'm holding steady at 1GB memory usage (I have 4GB, but it's actually showing 3.6GB, dunno why), no swap usage, and using right around 4% on cpu currently. HD capacity is only 28% used. Has anyone else ran into this issue? I love Ubuntu to death, but using other distros other than Ubuntu, I dont have this problem.

• Why not sync folders outside home with ubuntu-one?

  - by peer

  It took me a while to find out that with ubuntu-one I can sync only folders in my home-folder. On all other folders the ubuntu-one - option is available in preferences, but the actual actions are greyed out. The ubuntu-faq is quite clear on that: https://wiki.ubuntu.com/UbuntuOne/FAQ/CanISyncAFolderOutsideMyHomeFolder But I actually wonder why and if this is going to change and if there is a trick around it (an other one than setting my home to /) I personally dont have any important data in my home-folder other than the program-configs. All documents, pictures, music are on a folder called /data that is actually on a different partition. That makes it much easier when one wants to reinstall ubuntu.

• Using an iPad or Nexus 7 as an Ubuntu Second Monitor

  - by never4getthis

  Is there any way to use an iPad mini or a Nexus 7 as a second monitor through a cable? I dont want something like vnc, I need it to work through the usb cable (or any other cable). I imagine that the iPad will get a lot of hate around here, the reason why I am considering it is because of the larger screen (compared to the nexus 7). I think its self explanatory that I need this to work with ubuntu (as I am posting in this formum). Thanks for reading this highly unorganized, typo-flled (<--see what I did there?), un-cohesive post. Any help will be appreciated!

• HP Probook touchpad

  - by ScienceSE

  I wrote about this problem some weeks ago, but now the question is: "Why is touchpad works not so good as in windows". I tried some "experiments": When I use windows and if I accidentally touched touchpad - cursor isn't moving, also no clicks occurring. So in windows working with touchpad is quite normal, but in Ubuntu ?f I accidentally touch the touchpad even with my wrist - cursor is moving etc. In Windows, the cursor moves only when I touch it with finger. And... If, for example, I hold one finger on touchpad and simultaneously move the second finger on the touchpad - the cursor doesn't move, however in ubuntu he does. He's "super sensetive" in ubuntu or what? Also I tried to apply the option in "Mouse and touchpad", which called "Disable touchpad when typing", but nevertheless he isn't disabling when i'm typing... Note: this option is circled in red frame, i dont know is it a good "sign" ) What can I do to fix the problem?

• Graphical Mode breaks after suspend/ returning from Console

  - by Jack G

  When I try to go to a virtual console (ctrl alt f1) and return to f7, my screen freaks out. Its black with frequent white 'lightning bolts' flashing across the screen. Nothing works, but to force shutdown. Same when trying to resume from suspend. This doesnt happen every time, but very often. I dont know what information might be useful but: Ubuntu 12.10 ATI RS880M [Mobility Radeon HD 4200 Series] Gallium 0.4 on AMD RS880 this line in xsession-errors might be pertinent: (gnome-settings-daemon:1825): color-plugin-WARNING **: Done switch to new account, reload devices p.s. Ive tried the fglrx drivers but need the legacy drivers as described here, but nothing past a black screen.

• Nvidia Fullscreen Metanode "Sliding" Issue

  - by user68202

  i have 2 monitors, the left one is my "main" monitor with 1920x1080_120, the right one my second with 1680x1050_60. (i have a nvidia card setup with twinview) when i play a game or something in fullscreen mode, the full resolution is used in fullscreen (monitor 1 + monitor 2). i read something about the metanodes i can use to shut down the one monitor that i dont need durning a "fullscreen session". i used the following: Option "metamodes" "DFP-0: 1920x1080_120 +0+0, DFP-2: 1680x1050_60 +1920+0; DFP: 1920x1080_120 +0+0, NULL" Its working great, the second (right) monitor is shutting down when i press "CTRL ALT +" and is starting agin when i press the same keystroke. But in the second mode when the second monitor is "down", i got the full "monitor 1 + monitor 2" resolution on my first (left) monitor, i can move my mouse to the right to see the contents of the second monitor and move it again to the left to the what is normally seen on the first monitor. Its something sliding between the 2 monitors on one display. How can i avoid this?

• Why is my Workspace switcher view skewed

  - by Lee

  I have been using Workspace switcher in Ubuntu just fine but recently have encountered this problem. The windows in the switcher don't fill the screen. I must have pressed some combination of buttons somehow but can't find any information anywhere in regards to resizing them. As you can see in the screen shot it looks like a perspective view or something. http://i1115.photobucket.com/albums/k553/lmt337/Screenshotfrom2012-07-04103519.png I should also add I have a dual monitor setup and nvidia graphics. The switcher still works but the fact the screens dont fit my actual screens is driving me nuts. Thanks in advance for any help.

• wordpress restored from backup asking for ftp

  I backed up my /var/www/wordpress folder to my external harddisk and restored it back. Now when I add a new plugin I am asked for ftp access to my localhost. I wonder why ? As far as I could go /var/www/wordpress and its subfolders/files are own'ed by root. I have logged in to my wordpress as admin root. I dont know why I need to setup ftpd, but I tried that too. "http://askubuntu.com/questions/14371/how-to-setup-ftp-to-use-in-locally-hosted-wordpress" I am missing something really silly here.
