Sometimes when I work, I use more than one terminal and I find it inconvenient to switch between them when all of them were invoked using Ctrl+Alt+T. Is there any program or terminal that after launching would provide me with 4 independent terminals each of them would occupy ¼ of the screen while making it easy to switch between them, for instance by using the Tab key?
I have downloaded JLink package and unpacked it to /home/mkru/ARM/JLink_Linux_V498a_x86_64. Then I have added this path to my PATH variable. When I try to execute JLinkExe I get the following error:
Can not connect to J-Link via USB.
When I try to execute it with sudo I get:
sudo: JLinkExe: command not found
The only way to execute it with success is:
- to change directory with
cd /home/mkru/ARM/JLink_Linux_V498a_x86_64 - then run
sudo ./JLinkExe
Why does it work like that and how can I change this behaviour ? I would like to use JLinkExe without sudo and without the need to be in this specific directory.
When I try to download some files from launchpad.net my browser displays page full of different strange characters. I can see that last download was today but I am not able to download it. I am able to download files from different projects but not that one. Here is the link: gcc-arm-embedded-misc
I wanted to install arm-none-eabi-gcc and I have encountered the above error. I know that the problem is generic and I need to read lines above that message but after analyzing error lines I still do not know what to do to solve that issue. Here are error lines maybe anyone would be able to help me.

I have added some pre-compiled tools for developing ARM into the /home/charlie/bin/ARM directory. When I modify the path by PATH=/home/charlie/bin/ARM:"$PATH" I can execute arm-none-eabi-gcc in the terminal.
However when I run make I got this error:
/bin/sh: 1: arm-none-eabi-gcc: not found.
What is the proper mechanism to make new programs located anywhere to be executed like native binaries (for example gcc) and why was I able to run it in terminal after changing PATH but make had problems ?
If I use optirun to run playonlinux ( or PRIMUS_SYNC=2 primusrun playonlinux ) and then I choose a game that uses wine, does my game also use secondary graphic card ? I ask because I get low FPS as if I was using integrated graphic card. After launching the game I get following warning in Terminal: primus: warning: recreating incompatible pbuffer, can it cause any fps problems ? I have installed graphic driver and followed this tutorial HOW TO PLAY LEAGUE OF LEGENDS ON UBUNTU 14.04 to install League of Legends but I still get much worse performance than on Windows7 (around 30 fps on Ubuntu, 60 fps on Windows) ?
I have installed Xilinx ISE IDE following this tutorial: Install Xilinx Ise on the Ubuntu

I have to move files from one folder to another but they reside in totally different paths. The destination path is so long and complicated that I am not able to remember it. Is there any way to go first to destination directory then store the path in some variable lets suppose X and then go to source directory and write a command like that:
mv * $X
I have mount surround sound in Ubuntu 14.04. When I am testing it with command:
speaker-test -Dplug:surround51 -c6 -l1 -twav
eveyting sounds fine but when I am using System Settings > Sound > Test Sound, the results differ. I got poor performance on right channels(right channels pause about every 0,5 sec). While listening to music I get this poor performance from the second test and I do not get why.
I have installed Qt Creator using Ubuntu Software Center but when I try to run it nothing happens. There is no error message, no new process, no new window.
