How to fix “The system is running in low-graphics mode” error?
I am totally new to Linux, and Ubuntu.
I bought ASUS X53E Notebook, erased Windows and installed Ubuntu. First it worked ok.
Then when I started working with it, i opened the terminal, entered
sudo chmod 666 usr and then all the icons from the main panel disappeared + the whole system stopped responding.
I decided to restart the system. When restarted, a message appears:
the system is running in low graphics mode
and below it:
Your screen, graphics card and input device setting could not be detected correctly. You will need to configure it yourself.
But the "OK" button is disabled and if I press any buttons nothing happens.
If I enter
Ctrl-Alt-F2 it opens the bash terminal. But there commands
apt-get are not found and it says that
permission denied if i try to enter any folder like
If I enter the
su command it asks for the password I don't know.
When encountering this problem first, I reinstalled the whole Ubuntu. but today it happened again just the same.
What shall I do? maybe there is something wrong with the hardware? If I need to install another distribution of Linux could you recommend one? but I'd rather stick to Debian releases like Ubuntu. so how do I fix the problem?
PS: Please give answers in simple terms because am a newbie so i don't know what goes where yet.
