• Volume control keyboard shortcuts not working in 14.04?

  - by user295481

  I run Ubuntu 14.04 on a Sony Vaio CS series laptop. Normally, the volume is controlled by pressing Funcion+F2, F3, and F4 for mute, volume down, and volume up respectively. I accidentally reassigned the volume up keyboard shortcut to a different key. I tried resetting the keyboard shortcut by going into the keyboard shortcuts editor in Ubuntu and pressing Function+F4, but that didn't work. My mute function and my volume down functions both work flawlessly, but volume up doesn't work at all. Please don't answer telling me to change the keyboard shortcut in the Keyboard Shortcuts manager, as I have already tried that. Thanks for your help!

• Install Ubuntu or Kubuntu?

  - by squallbayu

  I want to upgrade my Ubuntu Lucid to Kubuntu Maverick (with a fresh install of course). I want to try KDE, but I have heard there are slight issues with the native QT applications compared to the GTK application equivalents - such as nvidia-settings, Gimp, Ubuntu Software Centre, and especially th eSynaptic package manager (which in detail showed the administration package / KPackageKit is not powerful yet than synaptic) I believe we can have run GTK+ applications in KDE, but GTK+ applications do not blend with the KDE desktop. Also Java does not provide a GUI for KDE/QT. Should I install Kubuntu (KDE / QT) or stay with ubuntu (GNOME / GTK +)?

• Bluetooth pairing of nokia with acer ubuntu 12.04

  - by Aneesh karthik C

  I have a Nokia 2700 classic phone. I tried installing obextool and Nokuntu. I run Nokuntu and find that every icon is enabled except for the Nokia Communication Centre, (it is greyed but is precisely what I need to be working!) I even tried connecting phone to laptop with a USB cable, and the same problem props up. I can also browse the contents of the phone as well as the memory card, in whichever way, either the Nautilus or Obextool file manager. The only issue that needs sorting is the communication centre.

• How to remove tearing in videos with Nvidia driver?

  - by Daimon

  I'm using ubuntu 11.10 as my HTPC OS on ION board. Tearing was always a big problem but this guide (http://www.omgubuntu.co.uk/2010/01/how-to-fix-video-tearing-in-videos-nvidia-ubuntu/) used to solve it in previous versions. I mean it used to because it doesn't solve it anymore. I tried making same changes (although compiz config is little different and same options are in different panels) but with no success. I also tried to manually set resolution and refresh rate of HDTV in nvidia settings - no changes at all. I know that open source drivers would solve a problem but it's not an option because I need VDPAU acceleration. I've also read that completely disabling of Composite solves the problem - can't do that because compizconfig-settings-manager crashes on attempt. More info about setup: Ubuntu 11.10 64bit Nvidia ION board newest official version of proprietary driver SMplayer with vdpau settings Full HD HDTV

• Switching to Kubuntu results in low graphics mode

  - by HackToHell

  I looked at some screen shots of Kubuntu and I liked it so I went to Synaptic and installed the kubuntu-desktop package and set my desktop window manager to kde and rebooted. After reboot, I saw Kubuntu splash screen then this message; running in Low Graphical Mode. Then I was not able to dismiss the message because my mouse did not work Seemingly How to Geek had the same problem http://www.howtogeek.com/howto/ubuntu/install-kde-kubuntu-on-ubuntu/ . You will probably see that your xorg.conf file was backed up to xorg.conf.1 during the ?KDE / Kubuntu installation. Just copy the xorg.conf.1 back to xorg.conf, reboot, and everything should be fine. I also tried to do that by booting into recovery mode and then droping onto the shell. But it would not let me rename, came up with some error.

• How to deal with project managers who micromanage?

  - by entens

  Perhaps I'm just naive, but when I try to decipher the wall of tasks I'm targeted to do over the course of a week, I just can't help but think whoever builds the project schedule needs to get some remedial training on basic project management. For example, I am assigned 13 tasks today, the shortest lasting .13 days (default time metric in Microsoft Project), and the longest lasting .75 days. I can't help but think that it is blatant micromanagement scheduling projects in sub 10 minute intervals. The effects of management are becoming evident in slipped tasks, resource assignment exceeding capacity by a factor of two at some points in time, and spending more time clearing tasks and figuring out what comes next than actually doing work. How can I convince the project manager to create tasks with larger duration and to see the larger picture?

• Getting Black screen after installing 12.04 on new Mac Pro

  - by Matteo

  I installed Ubuntu 12.04 on my new Mac Pro. I had some problems because bootcamp did not allow me to partition the hd without a Windows cd. I inserted a Windows cd and did the partition and then I stopped the installation. I completed the installation of Ubuntu that now works. The problem is that Grub can't start Mac OS. It sees the Mac OS X in the menu but if I try to start it I have a black screen or sometime just the boot manager. Has anyone else experienced this problem?

• Need instructions how to create wpa_supplicant.conf and add fast_reauth=0 to it // WPA 2 Enterprise & frequent wlan disconnects

  - by nutty about natty

  Like many other natty users on a university / academic network, I'm experiencing annoying frequent disconnects / hangs / delays. See, for instance: https://bugs.launchpad.net/ubuntu/+source/wpasupplicant/+bug/429370 I would like to learn how to add fast_reauth=0 to the wpa_supplicant.conf file. This file, it seems, does not exit by default, and needs to be manually created first: http://w1.fi/gitweb/gitweb.cgi?p=hostap.git;a=blob_plain;f=wpa_supplicant/README [quote] You will need to make a configuration file, e.g., /etc/wpa_supplicant.conf, with network configuration for the networks you are going to use. [unquote] Further, I installed wpa_gui which probably needs to be launched with parameters, else it's pretty blank... What I'm hoping for is this: That creating a wpa_supplicant.conf file with fast_reauth=0 in it, saving it to the relevant path, will work and make my uni wireless (more or even completely) stable. I read mixed reviews about wicd (as an alternative to the network manager). Also note that on my basic wlan at home (with bog-standard wpa encryption) the connection is stable. Thanks!

• Android Loading Screen: How do I use a stack to load elements?

  - by tom_mai78101

  I have some problems with figuring out what value I should put in the function: int value_needed_to_figure_out = X; ProgressBar.incrementProgressBy(value_needed_to_figure_out); I've been researching about loading screens and how to use them. Some examples I've seen have implemented Thread.sleep() in a Handler.post(new Runnable()) function. To me, I got most of that concept of using the Handler to update the ProgressBar, while pretending to do some heavy crunching work. So, I kept looking. I have read this thread here: How do I load chunks of data from an assest manager during a loading screen? It said that I can try using a stack it needs to load, and adding a size counter as I add elements to the stack. What does it mean? This is the part where I'm totally stumped. If anyone would provide some hints, I'll gladly appreciate it. Thanks in advance.

• Preventing pop-up dialogs when connecting an MTP device

  - by DrownedSensors

  I'm using Lubuntu 14.04 with a Samsung Galaxy S3 running Android 4.3. Each time I connect my phone via USB, I get the following dialog: Unable to open MTP device '[usb:002,023]' A few moments later, I get the "Removable medium is inserted" dialog, prompting me to open in File Manager. After that, the phone is connected and fully accessible. So MTP works. The problem is that I plug in my phone to charge every time I sit down, and unplug it every time I step away. Dismissing these two dialogs every time is a pain. I would think the "Removable medium" dialog is the easier candidate. How do I tell Ubuntu to take no action and stop prompting me? For the MTP error, all the discussion I can find is for people who can't get MTP working at all. For me, it's working, but only after throwing this initial error. I've verified that my device is present in /lib/udev/rules.d/69-libmtp.rules

• Ubuntu Splash Screen Customization

  - by Galaxy7

  I wanted to know how to customize the splash screen in Ubuntu 13. I have tried to install Plymouth Manager but when I run sudo apt-get update it says it was unable to fetch http://ppa.launchpad.net/mefrio-g/plymouthmanager/ubuntu/dists/raring/main/binary-i386/Packages. I opened the address in Firefox but it didn't open. Also I would like to know where the files for the Ubuntu Logo, Splash Screen Background, etc. are located (to customize them). In previous versions they were located at usr/share/images. I am running Ubuntu 13 Raring Ringtail on VMWare Player. The host is an Acer 5600U running Windows 8. Thnx.

• Event Driven Communication in Game Engine - Yes or No?

  - by Bunkai.Satori

  As I am reading book Game Coding Complete (http://www.amazon.com/Game-Coding-Complete-Third-McShaffry/dp/1584506806/ref=sr_1_1?ie=UTF8&qid=1295978774&sr=8-1), the author recommend Event Driven communication among the all game objects and modules. Basicaly, all the living game actors and object should communicate with the key modules (Physics, AI, Game Logic, Game View, etc..) via internal event messaging system. This would mean designing efficient event manager as well. My question is, whether this is proven and recommended approach. If it is not properly designed, it might mean consuming a lot of CPU cycles, which can be used elsewhere. This is especially true, if the game is targetted for mobile platform. What is your opinion and recommendation, please?

• Install a different version of a package

  - by Michael Wiles

  I'm running lucid server and have installed tomcat. The version it installed is 6.0.24-2ubuntu1.6. Is this the version I'm tied to? Is it possible to install a more recent version? The one available from maverick is 6.0.28. Maybe I can add a source to provide my lucid install with this version? In the package manager user interface I can "force version". Is it possible to force version from command line alternative as well?

• Login crash loop

  - by dawmail333

  After about the second/third batch of updates on a fresh install of Ubuntu 12.04, I end up getting stuck in an infinite login loop: I enter my password, screen goes black and shows me the end of the initialisation messages (including things like CUPS initialising), and then the greeter reappears. Kicker is, as I'm using gnome-shell, I just decided to uninstall LightDM, ubuntu-desktop and unity-greeter, using GDM as my manager, and the problem still happens in exactly the same manner. I'm lost even as to where to start looking - Xorg logs, LightDM logs (before I removed it), syslog and dmesg logs have held no unusual information at all. I have a TeX assignment due next week, and reinstalling Ubuntu every time I want to work on it is not going to work (nor is using TeX on Windows ;). Anything else I should try?

• Why do I need to relaunch dkpg-reconfigure keyboard-configuration after every startup?

  - by yves Baumes

  I've switched recently to an UK keyboard, from a FR keyboard. It is an usb keyboard, and first I plugged it in, I had to launch dpkg-reconfigure keyboard-configuration in order to request the correct layout (ie: uk). But after every reboot of the machine, the laytout comes back to the FR layout. How can I make the modification persisting? I am using Ubuntu, running the Stump Window Manager. And here is the /etc/default/keyboard at any time (that is right after startup, and before and after I run the dpkg-reconfigure tool) XKBMODEL="hhk" XKBLAYOUT="gb" XKBVARIANT="" XKBOPTIONS="terminate:ctrl_alt_bksp"

• Cool projects at Codeplex

  There’s a significant number of useful projects at Codeplex who were meeting with some of our needs.

• How to prevent Ubuntu from changing screen brightness?

  - by cholazer

  I have recently installed 12.04 on ASUS-K53SV-V300. I can change the brightness on start-up with: echo 0 > /sys/class/backlight/acpi_video0/brightness >> /etc/rc.local or manually by Fn key. But, whenever Ubuntu dim my screen brightness to save power or wake-up from suspend or inactive for 20-30 seconds, brightness reset to high (my problem get much more when on battery). How can I disable screen brightness service to prevent it from changing my brightness? What service work on screen brightness? If I disable this service, can I manually set brightness by command? I found a program to work on brightness instead of default power manager.
