After being away for a while, totally on windows 8, I’ve setup my old laptop to be totally on lubuntu.
It is core2duo processor, 2G RAM and 320 GB HDD.
This laptop had windows 7 and ubuntu.
Now, it is the only lubuntu 15.04.
One thing, I’d like to share is how to change the default browser from firefox to chromium.
In the terminal:
sudo update-alternatives –config x-www-browser
then choose your favorite browser
Hope to write soon on something new on lubuntu
Dell XPS 15
1- Download Linux Mint iso
linuxmint-201403-cinnamon-dvd-64bit.iso
2- On Windows download Universal-USB-Installer
Universal-USB-Installer-1.9.5.2.exe
3- Prepare live usb or sdcard of Linux Mint:
a. Run Universal-USB-Installer
b. Choose your usb flash drive or sd card
c. Select Linux Mint
d. Browse to the path of the iso file
e. Install
4- Leave live usb created in step [3] attached.
5- Restart PC
6- When seeing Dell logo, press F12 to select Boot
7- Your live usb will be seen in the UEFI boot list, select it
8- Live Linux Mint will load.
9- Note that the touch pad will not be able to click with it unless press it as a button and not the normal tapping. The scroll is also lost. It is better to use an ordinary mouse first to change the setting of the touch pad to enable the click and the scroll.
10- Click on install Linux Mint icon on the desktop
11- Follow the steps and choose carefully the external hdd. You can loose your data if another hdd was selected. Be careful
12- Before going into the partitioning steps, linux partitioning app (gparted) may warn you about gpt partition not in the correct location in your windows hdds. I simply ignored those warnings. The fix may damage how windows start or work. Because windows using intel smart technology to raid both hdds SDD and sata. If you really know what you are doing, go ahead and fix it otherwise ignore the fix.
13- Partition the external hdd exaclty as follows:
a. EFI boot partition: It must be the first. Partition type: fat32. Size 511 MB (I’ve read it from an article, I am not sure how it is calculated. But it worked for me. You can try otherwise if you like). Mount to [/boot/efi]. manage the flags of this partition to be boot. format it vfat
b. System partition: Partition type: ext4. It will have the system files (after the first setup system files took around 4.5 GB. I made it 100 GB. I am planning to setup a lot of fat development apps). Mount it to [/]. Format it ext4.
c. Swap partition: some articles says that it should be double your RAM size. I did so. You can experiment with that.
d. Home partition: Partition type: ext4. It will contain all your personal data. This should be the largest partition. You can store musice videos , photos, projects, etc. Mount it to [/home]. Format it ext4.
14- When you asked for the location of the boot loaded after the paritioning phase select the partition of EFI boot [e.g. /dev/sdd1]. You cannot select the hdd [e.g. /dev/sdd], It will not boot. You must select the partition of EFI boot [e.g. /dev/sdd1].
15- Complete the setup to the end.
16- Reboot your PC.
17- When seeing Dell logo, press F2 to enter the BIOS settings
18- From Boot menu disable the secure boot.
19- Save changes and reboot PC.
20- When seeing Dell logo, press F12 to select Boot
21- Your Linux Mint on ext hdd will be seen in the UEFI boot list, select it
22- This is how it worked for me. Good luck.
23- If the boot option for Linux Mint disappeared
24- Enter Bios, create a new boot option
25- Select the usb partition with efi boot
26- Write the path to efi file: \EFI\linuxmint\grubx64.efi. if this did not work, find the path to efi file as follows.
27- From windows, run command prompt
28- diskpart
29- list disk
30- select disk 2: this is my usb external hdd
31- list partition
32- select partition 1
33- assign
34- run file explorer, you will see the efi boot partition with a new letter, click on it and browse the efi file. Save that path to the file. This is what to write in Bios setting new boot option
35- Hope this helps
Turn your android cellphone to a wireless mouse using ulimate control from negusoft.
You only need to setup Ulimate Mouse Lite app on your cellphone.
Then setup ucontrol receiver on your PC. It supports Linux, Mac and Windows.
After setup on linux, to use the bluetooth connection you need to setup a bluetooth library as follows:
sudo apt-get install libbluetooth-dev
The following post is based on the original post in stackoverflow site . The answer done by JapSlap and Kate Gregory.
I’ve just added some dependencies based on my installation experience and some configuration.
Step 1: download shrew soft package Download the latest linux schrew soft vpn package here:http://www.shrew.net/download/ike
At the time of writing (May 6th 2013) the file is ike-2.2.1-rc-1.tgz
Step 2: untar package Untar this into a directory and navigate to the folder created called ike
Step 3: try to prepare for install run this command:
cmake -DCMAKE_INSTALL_PREFIX=/usr -DQTGUI=YES -DETCDIR=/etc -DNATT=YES
Step 4: install dependencies the initial cmake command failed for me the first two times because I needed to install these dependencies:
sudo apt-get install libedit-dev
sudo apt-get install libqt4-core libqt4-dev libqt4-gui
sudo apt-get update && sudo apt-get install build-essential
sudo apt-get install g++
sudo apt-get install libcurl3-openssl-dev
sudo apt-get install flex
sudo apt-get install bison
sudo apt-get install checkinstall
Step 5: prepare for installation: Run this command again:
cmake -DCMAKE_INSTALL_PREFIX=/usr -DQTGUI=YES -DETCDIR=/etc -DNATT=YES
Step 6: install the application using this command
sudo checkinstall
sudo ldconfig
sudo cp /etc/iked.conf.sample /etc/iked.conf
Step 7: launch the shrew soft daemon
sudo iked
Step 8: launch the graphical interface
sudo qikea
Step 9: use the import feature or set up a new connection
You’re done!
Recently, I’ve succeeded in connecting to my desktop computer using my laptop using secure shell command (ssh). It was my first time to use ssh.
I’d like to share this experience with you.
I tried to play audio on Ubuntu 12.04 64bit and the source files were on Ubuntu 12.10 32bit.
Source computer: the computer with the audio files.
Client computer: the computer with the speakers attached on.
First I’ve installed the secure shell server on the source computer using the following command
sudo apt-get install openssh-server
Then I’ve installed paprefs on the source computer
sudo apt-get install paprefs
paprefs
I’ve configured my source computer as follows:
Network Access:
check Make discoverable PulseAudio network sound devices available locally
Network Server:
check Enable network access to local sound devices
check Allow other machines on the LAN to discover local sound devices
Simultaneous Output
check Add virtual output device for simultaneous output on all local sound cards
I’ve installed paprefs on the client computer
sudo apt-get install paprefs
I’ve checked on the port of PulseAudio
pax11publish
by default it is 4713
using the following shell command to connect to the source computer
ssh -C -R 24713:localhost:4713 user@SourceComputerIP -X
-C: compress the network info, speeds up the connection
-R: use port forwarding, we have used the PulseAudio port got in the previous step
-X: to use the client computer display for the source computer applications
After the shell command, on the source computer
export PULSE_SERVER=”tcp:localhost:24713″
to transfer the PulseAudio stream to the port of the shell forward
Now every thing is configured try the vlc to play any audio / video file.
As a newbie to ssh command, I am really enjoying it.
I’ve been using Remmina Remote Desktop Client for a while now. But recently it kept freezing on rdp remote connection with a windows machine. It was so frustrating, till I used rdesktop.
Please use the following command to install it (if it is not already installed)
sudo apt-get install rdesktop
You can specify the resolution you want or to make it run full screen.
rdesktop -f [the machine ip]
To exit the full screen press ctrl+alt+enter
To specify certain resolution or percentage of your current machine resolution use one of the following commands:
rdesktop -g 1024×768 [the machine ip]
or
rdesktop -g 90% [the machine ip]
the command line has many options,I am currently trying it out.
I had a problem when trying to connect my laptop “HP ProBook 5310m” to a projector using a VGA converter plugged in my DisplayPort. The best resolution I got was 1024×768. I know the projector can display a higher resolution.
Recently, I found the following steps in askubuntu site and I’ll try it out.
You must add the resolution with:
xrandr --newmode <ModeLine>
To know the ModeLine of your resolution, do this:
$ cvt 1650 900
You will get some like this:
# 1656x900 59.93 Hz (CVT) hsync: 55.98 kHz; pclk: 122.25 MHz
Modeline "1656x900_60.00" 122.25 1656 1752 1920 2184 900 903 913 934 -hsync +vsync
Then, copy the information after the word “Modeline” into the XRandR command:
$ xrandr --newmode "1656x900_60.00" 122.25 1656 1752 1920 2184 900 903 913 934 -hsync +vsync
After the mode is entered, it needs to be added to the output:
xrandr --addmode VGA1 1656x900_60.00
Now you have the new resolution 🙂
