If you are using ubuntu type this command in the terminal
sudo apt-get install nautilus-image-converter
press enter key type your password
after this you need to restart your desktop manager for that type ALT + F2 in your keyboard then type “r” then press enter key this will restart your desktop manager now your newly installed extension will be loaded to the right-click menu, if not please restart your pc, see the snapshots given below
By default gnome came with Fahrenheit as the unit for weather app , Fahrenheit was used as the official temperature scale only in the United States (including its unincorporated territories), its freely associated states in the western Pacific (Palau, the Federated States of Micronesia and the Marshall Islands), the Bahamas, Belize, and the Cayman Island. All other countries in the world now use the Celsius scale.
I am using Fedora and gnome as DE to change Fahrenheit to Celsius in gnome weather app you need to open terminal then type following command line
gsettings set org.gnome.GWeather temperature-unit "'centigrade'"
Now open gnome weather app again, by now the temperature unit scale will be changed from Fahrenheit to Centigrade .
to change Centigrade to Fahrenheit use this command line
gsettings set org.gnome.GWeather temperature-unit "'fahrenheit'"

Internet Protocol Version 6 (IPv6) is a network layer protocol that enables data communications over a packet switched network.
Packet switching involves the sending and receiving of data in packets between two nodes in a network. The working standard for the IPv6 protocol was published by the Internet Engineering Task Force (IETF) in 1998.
The IETF specification for IPv6 is RFC 2460. IPv6 was intended to replace the widely used Internet Protocol Version 4 (IPv4) that is considered the backbone of the modern Internet.
IPv4 currently supports a maximum of approximately 4.3 billion unique IP addresses. IPv6 supports a theoretical maximum of 2128 addresses (340,282,366,920,938,463,463,374,607,431,768,211,456 to be exact!).
IPv6 and IPv4 share a similar architecture. The majority of transport layer protocols that function with IPv4 will also function with the IPv6 protocol. Most application layer protocols are expected to be interoperable with IPv6 as well, with the notable exception of File Transfer Protocol (FTP)
An IPv6 address consists of eight groups of four hexadecimal digits. If a group consists of four zeros, the notation can be shortened using a colon to replace the zeros.
A main advantage of IPv6 is increased address space. The 128-bit length of IPv6 addresses is a significant gain over the 32-bit length of IPv4 addresses, allowing for an almost limitless number of unique IP addresses.
IPv6 features —————-
* Supports source and destination addresses that are 128 bits (16 bytes) long.
* Requires IPSec support.
* Uses Flow Label field to identify packet flow for QoS handling by router.
* Allows the host to send fragments packets but not routers.
* Doesn’t include a checksum in the header.
* Uses a link-local scope all-nodes multicast address.
* Does not require manual configuration or DHCP.
* Uses host address (AAAA) resource records in DNS to map host names to IPv6 addresses.
* Uses pointer (PTR) resource records in the IP6.ARPA DNS domain to map IPv6 addresses to host names.
* Supports a 1280-byte packet size (without fragmentation).
* Moves optional data to IPv6 extension headers.
* Uses Multicast Neighbor Solicitation messages to resolve IP addresses to link-layer addresses.
* Uses Multicast Listener Discovery (MLD) messages to manage membership in local subnet groups.
* Uses ICMPv6 Router Solicitation and Router Advertisement messages to determine the IP address of the best default gateway.
Adding a Temporary IPv6 Address on Linux. =================================
Using “IP” ———-
/sbin/ip -6 addr add <ipv6address>/<prefixlength> dev <interface>
eg: /sbin/ip -6 addr add 2001:49f0:2920::a2/64 dev eth0
Go to nvidia website and download driver, for this tutorial i am using .run file copy the file to your desktop , after that simply right click and select properties > select permissions > tick Execute : allow executing file as program ,
after that you need to black list nouveau for that type following command in the terminal
sudo nano /etc/modprobe.d/blacklist-nouveau.conf
then copy following text in the nano editor in terminal then save it
blacklist nouveau blacklist lbm-nouveau options nouveau modeset=0 alias nouveau off alias lbm-nouveau off
then type following command in the terminal
sudo update-initramfs -u
reboot your system after this procedure , now you can find your system resolution is changed from recommended to minimal,once login screen appear press Ctrl + Alt +F1 this will switch your interface from GUI to CLI then login by typing your username and password after that you should stop your Desktop Manager, by default ubuntu using lightdm you type following command in the terminal to stop lightdm
sudo service lightdm stop
this will stop gui service running in background then you should navigate to your nvidia driver location by typing cd /Destkop
if you type ls you can find driver which you have copied earlier
after that you need to execute driver installation file for that type following command in the terminal
Please note the driver version which you are using may vary
then follow the instructions !
after installation reboot your system
in my system i have two cards one is Nvidia quadro K2200 & Tesla k40c
so i am going to install cuda to install cuda type follwing command line in the terminal , offline installation is also available i will include that tutorial in the future blog post if you want to download offline cuda package you can download it from https://developer.nvidia.com/cuda-downloads
sudo apt-get install nvidia-cuda-toolkit
this package is around 750 mb , installation speed is depend on your internet connecton, after installation reboot your system, to confirm whether both graphics card is detected in your system you can use inxi utility for that install inxi package in your system by typing
sudo apt-get install inxi
after the installation , open terminal and type
congratulations you have successfully install both nvidia driver and cuda
