GUI no longer starts

Unread postby mattmaz » Thu Aug 16, 2018 8:41 pm

After rebooting, my XU4 with Ubuntu doesn't boot to the GUI. I get a prompt to enter the root password for maintenance. After that, I just get the root prompt. How do I get the GUI back?

Thanks

Try to backup your important data first.
What happens if you run sudo systemctl start lightdm.service from the prompt?

If your root file system was too much corrupted, you might need to freshly install the Ubuntu 18.04 Mate image(ubuntu-18.04-4.14-mate-odroid-xu4-20180501.img).

When I try to above command, there is a long pause, then "Job for lightdm.service cancelled."

I'll try reflashing next. I'm waiting for a USB adapter for the microSD card. The port adapters I have to use the full size SD card slot don't seem to work.

Thank you.

I reflashed the MMC module with ubuntu-18.04-4.14-mate-odroid-xu4-20180501.img
Everything is working now.

Thank you for all the help.
