NVIDIA GT30 Ubuntu 17.10 installed unable to boot keeps freezing

Few days ago I installed NVIDIA GT30 in my local station for how many times and it was successful installation.

but once system is rebooted.. Then the problem occur, I was stuck in the encrypt login screen, I do have files encryption… Cause I encrypted my home folder and put password in it, before you can proceed to the user desktop login screen you need to enter password for security purposes

Image result

Once rebooted there’s no mouse or even keyboard activity so you can enter password to login.. Its like the system totally freeze

You cant click or even ctrl + alt + delete etc.. completely nothing

for how many hours debugging the issue and searching in the web.

found this blog


I was reading it and it came up in my mind that maybe the visual login screen is the issue for some reason keep the system freeze.. I’m just guessing it.

then force to reboot the computer by pressing the CPU power button long press then switch to recovery mode.

then Switch to tty1 by ctl-alt-f1 and login

then I updated the grub file

see below

xx@xxxx:~$ nano /etc/default/grub
From: GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash noplymouth"

quiet means you’re not be able to see any visual login screen and just a command line screen to login.. nothing special.


then guess what after rebooting the system, I’t went well and I can now login using command line screen login.

Linux Command: SCP (Secure Copy)

I was about to transfer huge files from server to server using linux.

Having issue with the transfer using FTP, download upload etc..

Then while searching on the web I read about this command name SCP (Secure copy)

Here the command definition:

Scp (Secure Copy) is a command line tool to copy or transfer files across hosts. It uses the same kind of security mechanism like the ssh program. Infact it uses an ssh connection in the background to perform the file transfer. scp refers both to the “protocol” that defines how secure copy should work and the “program” (command) which is installed as a part of OpenSSH suite of tools.

The Syntax for SCP is:

The syntax for scp is:

If you are on the computer from which you want to send file to a remote computer:

scp /file/to/send username@remote:/where/to/put

Here the remote can be a FQDN or an IP address.

On the other hand if you are on the computer wanting to receive file from a remote computer:

scp username@remote:/file/to/send /where/to/put

scp can also send files between two remote hosts:

scp username@remote_1:/file/to/send username@remote_2:/where/to/put

So the basic syntax is:

scp username@source:/location/to/file username@destination:/where/to/put

You can read man scp to get more ideas on this
