I mainly work on AC power. Therefore Windows has the below utility to improve battery life for my scenario by disabling battery charging:

How do I achieve this in Ubuntu?

Thanks in advance!

My Ubuntu touch application requires a package called libqt5network5 to run. (This is installable via APT.)

Once I build the Click Package from Ubuntu SDK and install, it does not check for the libqt5network5 dependency.

I wish to know how to add dependencies to Click packages.

My situation:

• I have created an Ubuntu touch application using Ubuntu SDK, in QML & C++.
• The application uses Ubuntu UI Toolkit (Ubuntu.Components 0.1)
• I want the application to run in other GNU/Linux distributions as well.

How to deploy this application along with Ubuntu Components, so that it runs on other GNU/Linux distributions as well?

Here is my situation:

Does anyone know how to change colour of the bottom toolbar?

Everytime I reboot, I've to turn off and on hotcorners from unity-tweak-tool. Other wise hot corners don't work. Any fix??
Thanks in advance!

According to this, Intel has dropped support for Mir. What is the effect on end user?

I like to know, what are the advantages of Mir.

Can I get this plug-in working on latest Ubuntu?

Thanks!

I've tried :

avconv -f alsa -i pulse recod.wav

..but it doesn't capture anything. Have any idea?
Thanks!

Please give me directions to compile & install Emerald specifically in Raring Ringtail 64bit edition. I've tried to compile it from the source many times, but had no luck.(Compile log : http://paste.ubuntu.com/5612178/)
Thanks in advance!

I arranged a transparent Squid proxy which listens to port 3128 on localhost, to block some web sites.

I've tested the proxy using Firefox, and it works.

Then I ran this, hoping to redirect all the http requests to the proxy:

sudo iptables -t nat -A PREROUTING -p tcp -j REDIRECT --to-ports 3128

Sadly, nothing happens. The other browsers in my system don't seem to be using the proxy. I don't want to configure each browser, to use the proxy either.

sudo iptables -L shows no rules assigned.

I'm on Ubuntu 13.04, and using a 3G USB modem (ppp0) to connect to the Internet. Any advice is appreciated!

If so, how could mobile carriers like AT&T lock the phone to work only with their SIM?
Thanks!

As FFmpeg is going to be dropped from Ubuntu, it will be important to know how to broadcast videos over Intrnet using avconv. An official guide is available, but it doesn't give much information how to work it out, step by step...
I have tried several times, but no luck.
Your simple & complete instructions are highly appreciated....!

Thanks!

There are two Ubuntu PCs called A and B.
A and B are connected to the Internet using two separated Internet connections. (In my case, two mobile broadband connections ppp0 x2 )
Each connection has a unique & static public IP address.

What I need is to control A computer's cursor, using B computer's mouse, over the Internet.

• In both computers, I have allowed other users to control my computer in Desktop Sharing preferences, as below:

  

• When I try to connect to A from the B using Remmina Remote Desktop Client, it refuses to connect after trying for a while.
  These are my settings:

  

I expect this to be done from an available open source software, not from TeamViewer.

I found this guide harder to understand.
Please provide me clear instructions...

Thanks for having a look!

Well, I like to mark /usr/bin/program.sh as executable using following command:

chmod +x /usr/bin/program.sh

I want the above command to be executed at the end of installation of the Debian package.

Is there a painless way to inject the command into the deb?

Thanks for looking!

rfkill list output :

..but my WiFi works fine.

In Windows I had to install Dell Wirless 365 Bluetooth driver to get it working. I installed BlueMan in Ubuntu, but it doesn't show any Bluetooth adapter. When I try to apply a kernel patch described here , it ends up saying:

patching file src/wl/sys/wl_linux.c

Hunk #1 FAILED at 332.

1 out of 1 hunk FAILED -- saving rejects to file src/wl/sys/wl_linux.c.rej

Thanks for any help...

Can somebody please make a short & sweet tutorial telling how to forward an Internet connection to different network interfaces in Ubuntu...?
This is the idea:

I'm using a 3G usb modem to get Internet on my laptop ,which is:

ppp0 IP=10.225.174.70

My Wifi device is:

wlan0 MAC=78:e4:00:d4:3d:85

These devices are determined from ifconfig command.

I want to share ppp0's internet connection with wlan0 device, so I can connect any other device to wlan0 and browse internet from that device.

Making a Hotspot using Network settings GUI doesn't do the trick because the other device won't receive Internet, it just connects to wlan0.

I heard iptables can do this, but I'm totally confused by the alien commands seen online. I'm no expert in networking. Please compose a clear & simple answer using the above devices. This is a huge annoying problem for iPhone & tablet users came to Ubuntu from Windows.

On Ubuntu 12.04, UbuntuOne client has never worked out for me. It just hangs at "File Sync Starting" everytime. I've used all the workaround terminal commands, but nothing works. Now I'm fed up with the desktop client.

Is there any other way to use UbuntuOne without the default client?

Any other new fix appriciated! Thanks!

For a very long time, I'm experiencing this bug in Compiz. It makes my windows flash, when rotating the desktop cube. None of the animations work properly execpt the Wobbly windows. However the temporary fix I found on the bug page helped me to reduce the effects, but it's not 100% perfect.

Now they have totally fixed the bug in Compiz 0.9.8 for Quantal. I really need to get the official fix on my Ubuntu 12.04. Don't the LTS versions get bug fixes?

Sometimes my desktop cube/cylinder appears like this :

None of this happened in Lucid Lynx :(

I want to install PeaZip for a specific purpose, which I can't fulfill with any other archive manager. I downloaded and installed it by using both dpkg -i & Gdebi. Now I can't start it, because I can't find the launcher. Please provide a solution.
