##Privacy in Ubuntu
This is a real thing. I did not know about it before I search for how to partition Ubuntu and there were dispute in the resources that I fouind between only SSD and hybrid drives (SSD + HDD). Some mentioned TRIM (i dont know what it is) to be enable and some ignores it all along. Some say do not use SWAP as it wears down the SSD and some say it is OK. Here some guides that I think should be informative and trustworthy however I haven't found any official best practice on partitioning SSD for Ubuntu.
- https://www.youtube.com/watch?v=8OKjSOUgLJU this video is on point. must watch.
- https://help.ubuntu.com/community/PartitioningSchemes this is official ubuntu community guide but no mention of SSD only setups. Very dissapointing.
- https://sites.google.com/site/easylinuxtipsproject/ssd this is a very extensive resource but not for ubuntu but linuxMint. I think it should be more or less same.
I have noticed extreme screen flickering in my PC when installed Ubuntu 18.04 (do not know about previous version though). A signle google search lead me to github issue link that solved the issue.
- Open Terminal
sudo nano /etc/default/grub- change the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"toGRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_rc6=0" - save the file with
ctrl + Oand exit the editor withctrl + x sudo update-grub- reboot the PC This should work.

- How to change kernel boot parameter: https://askubuntu.com/questions/19486/how-do-i-add-a-kernel-boot-parameter
This is also an issue I have faced with the first boot of Ubuntu. But after installing Microcode as per the suggestion of same github project, running sudo apt install intel-microcode fix the problem.
This should work.
- Razer Blade Linux: https://github.com/rolandguelle/razer-blade-stealth-linux#install
While writing this repository, my ubuntu stopped working suddenly and froze the whole system including mouse and keyboard. Quick google search led to askubuntu forum but the solution requires the SysRq key but Razer Blade Stealth does not have that.
I have tweeted to @rolandguelle asking some help for the guide available to best partitioning practice for SSD only PCs. Found two links that explain the partitioning on SSD.
- https://sites.google.com/site/easylinuxtipsproject/ssd (I find this one more useful as per my understanding level of Ubuntu and hardware-software in general)

Still Pending...
Google Chrome is a must have web browser in my opinion. Initially, not seeing it in Ubuntu App Store dissapointed me but then I found out that it needs to be installed through normal downloading the .deb file and install it. This should works.
Downlaod .deb file from Oracle V box official website Double click and isntall. It is raising an error as below when I run any irtual environment.
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
'/sbin/vboxconfig'
as root.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.
Installing VirtualBox by downloading and running was a bad idea I suppose.
Quick fix was to run sudo apt-get install virtualbox and run virtualbox
This should work.
One thing I often do is flashing custom ROMs to my OneplusOne device. I needed to get the access of storage system of mobile device in my ubuntu system when it is on fastboot mode or recovery mode. One thing perticularly I wanted is to access internal storage once fully wiped down in recovery to add the rom at that point of time (for fresh install).
I forund this amazing amazing that allow me to install appropriate drivers and tools. I have run the code as it is given in the page but for the sake of preservation I will note them down here.
- Install Android Tools
sudo apt-get install android-tools-adb android-tools-fastboot - Update to latest ADB and fastboot
#check adb version before
adb version
wget https://dl.google.com/android/repository/platform-tools-latest-linux.zip
sudo unzip -d /usr/local/sbin platform-tools-latest-linux.zip
sudo wget -O /usr/local/sbin/adb https://raw.githubusercontent.com/NicolasBernaerts/ubuntu-scripts/master/android/adb
sudo wget -O /usr/local/sbin/fastboot https://raw.githubusercontent.com/NicolasBernaerts/ubuntu-scripts/master/android/fastboot
sudo chmod +x /usr/local/sbin/platform-tools/adb /usr/local/sbin/adb
sudo chmod +x /usr/local/sbin/platform-tools/fastboot /usr/local/sbin/fastboot
#check adb version after
adb version
- Declare vendor ID for ADB I think it is not necessary for me as my phone is old enough (5 year old to be precise) to recognized by any version of adb as of 2018. But I would note down to code regardless.
mkdir --parent $HOME/.android
wget -O $HOME/.android/adb_usb.ini https://raw.githubusercontent.com/NicolasBernaerts/ubuntu-scripts/master/android/adb_usb.ini
- Setup ADB Udev Rule
Your device ned to be in USB debugging mode for the next step.
lsusbYou should found your phone in the list.
sudo wget -O /etc/udev/rules.d/51-android.rules https://raw.githubusercontent.com/NicolasBernaerts/ubuntu-scripts/master/android/51-android.rules
sudo chmod a+r /etc/udev/rules.d/51-android.rules
sudo service udev restart
- Allow ADB trusted connection
adb devicesAllow the request of adb in your phone and rerun the command for your pc to recognize the device. - Install QtADB
Prerequisite: Your phone needs to be rooted and install app BusyBox
Run the following command to confirm the BusyBox install.
adb shell busybox ls -l -a
Installation process
sudo apt-get -y install libqtgui4 libqt4-network libqt4-declarative
wget -O qtadb.tar.gz http://motyczko.pl/qtadb/QtADB_0.8.1_linux64.tar.gz
tar -xvf qtadb.tar.gz
sudo mv ./QtADB*/QtADB /usr/local/sbin/qtadb
sudo chmod +x /usr/local/sbin/qtadb
rm qtadb.tar.gz
rm -R QtADB*
- It might crash at this point when run the following
qtadb
fix this crash by following
mkdir --parents $HOME/.config/Bracia
wget $HOME/.config/Bracia/QtADB.conf https://raw.githubusercontent.com/NicolasBernaerts/ubuntu-scripts/master/android/QtADB.conf
rerun the above command to confirm fix. 8. Create application launcher with icon and place in all applications
