Uslikao sam što sam napravio u terminalu, ali ne mogu ući u Ubuntu da pošaljem sliku, i evo dokle sam došao i link što sam pratiohttps://sites.google.com/site/easylinuxtipsproject/ssd
"After the installation: noatime
7. With "noatime" in /etc/fstab, you disable the write action "access time stamp", that the operating system puts on a file whenever it's being read by the operating system. For an SSD "noatime" is much better.
You can do that as follows:
a. First make sure that you have installed the applications gksu and leafpad:
Launch a terminal window.
(You can launch a terminal window like this: *Click*)
Type (or copy/paste):
sudo apt-get install gksu leafpad
Press Enter and submit your password. Please note that the password will remain invisible, not even asterisks will show, which is normal.
b. Then type in the terminal (use copy/paste):
gksudo leafpad /etc/fstab
c. Now add "noatime" to the line for your root partition and your other Linux partitions. Not to the line for the swap partition!
An adapted line may look like this:
UUID=xxxxx / ext4 noatime,errors=remount-ro 0 1
Note: there should be no space after the comma after noatime! Otherwise boot failure will probably occur. See the example line above.
d. Save the modified text file and close it."
E ja nisam znao spremiti, i tu sam zapeo.
e. Now proceed to the next item.
