Problem when I start the OS

Huamin · 07-18-2015, 02:51 AM

Hi
I don't know how I can change the interface to prompt for different user account, when I start the OS below. Can you please help, as Oracle Linux is also Red hat,

and it now does only prompt with the above, after I have started the OS.

I'm not sure what you mean by that. It does not default to any specific user account. You specify which user account you want to log in to (eg. root, or any other that exists on that system).

Do you mean that it used to default to a graphical logic interface and now it stops at a command line login?

Yes, I expect to have the way to have the graphic user interface, when I've started the OS. Thanks a lot.

Assuming your X Windows system is installed and works correctly, try changing the default runlevel

Is this machine really running as a server or do you use it for your everyday tasks?

Two more possibilities.

Likely: You don't have desktop software installed. If it were Red Hat or Centos, you would automatically get a graphics screen login prompt after installation of desktop software.
How to install desktop software depends on the Red Hat and Centos version. Don't know for Oracle Linux.

Unlikely but easy to check: Perhaps the GUI is actually running. Try hitting ALT-F1 (the Alt key and the F1 key at the same time). This brings you to the first virtual terminal, where the GUI is normally displayed.
Then the question is why you are not shown the graphics screen when the system boots. I can't say.

Questions:

Has it ever worked?
How was this system installed?

What happens when you enter this command?

Code:

startx

Sorry, can you please advise to this?

You can't use gedit without a running Xserver.

The errors would indicate that there is no X server nor X applications, including gedit, installed.

As asked earlier, has this machine ever had a working X server and graphical login?

To edit the inittab if you want to try to change runlevel anyway, try with a non-graphic editor, like this...

Code:

vi /etc/inittab

OR

vim /etc/inittab

OR

nano /etc/inittab

Many thanks. which level to adjust to, within file "/etc/inittab"?

According to your picture, you need to type graphical where it has <target.name>.

Huamin · 07-20-2015, 03:51 AM

It is the same, while I have this

now.

Leave the inittab. At your shell prompt, type ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target. This makes the GUI the default boot target - that is, you will boot into GUI mode.

From the other facts you have posted, it's very likely you don't have GUI software installed and will again end up with a command prompt. Still, it's worth the while to set the target to graphical.

And a piece of advice. If you want to manage a server OS like Oracle Linux, you need a minimum of education. You could, for example, read the documentation. I don't know what Oracle provides, but Red Hat has very decent guides at access.redhat.com. Start with the deployment guide; it tells you how to configure systemd.
