after upgrade 18.04 no gui available only tty [closed]

Question

After upgrading my Ubuntu desktop from 17.10 to 18.04, everything went smooth until I restarted my PC.

The first suspicious thing I noticed was that it has the same grub with 17.10 - it selected the old grub from the menu (auto-select) and then showed me the boot screen. But afterwards instead of GUI I got terminal access (tty1) only.

How can I fix that? I tried running:

sudo update-grub

but with no luck and the initial grub is still the same. How can I fix this problem?

@KhaledE I didn't mate... I have just reinstalled it from scratch (the only drawback was to configure everything all over again) – Vickey

Try startx. I had the same problem but it worked for me. The solution is to start lightdm by yourself. The installation is indeed broken in some systems. startx command starts the GUI process for you.

Check status of display manager by executing - sudo systemctl status lightdm

Try restarting display manager by executing - sudo systemctl restart lightdm

If this doesn't work, then you should try reinstalling Ubuntu.

Same problem here but no networking on tty. Selecting Enable Networking from the recovery menu does nothing so can’t install anything. Short of reinstalling, which is really not a good option, how does one move forward? – Rexanne

in case of you still have the GUI it works but when it broken you have to re-install the gui – Chobot

I just used

sudo apt-get autoremove
sudo apt-get autoclean

And installed the nvidia graphics from terminal

It worked for me.

Restored the grub config to same file. "quite splash"

Plus my ubuntu was 20.04 LTS
