I updated from 15.04 to 15.10. When I start up the computer I see

Error: no video mode activated

After this, it goes to the Ubuntu startup page with the logo but after load shows me a list of services that have started and stays on that screen. I am getting very frustrated. Ubuntu left a message saying that 15.04 will no longer receive updates and I should switch, and this version is broken upon arrival.

I can use the Ctrl+Alt+F1 command to put in commands but have no idea where to start. Please help.


This seems to be a bug. Maybe you can boot from the Livecd, and try to reinstall GRUB.

  • Use live cd and choose to install Ubuntu.

  • Don't Format partitions already created.

  • Chose mount point for each partition, and then select continue. The grub installer will be reinstalled correctly.

Or Try to Commit: _GRUB_HIDDEN_TIMEOUT_ and _GRUB_HIDDEN_TIMEOUT_QUIET_ in /etc/default/grub will help on this: Then try to run 'sudo update-grub' after changes to /etc/default/grub.

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
  • I am unsure if this alone would have fixed my issue as I also copied font files as described at askubuntu.com/a/83736/67747 - together those fixed my issue. – sage Jun 20 '17 at 21:56

Especially if you run an encrypted drive and you have nvidia drivers installed then you can try:


sudo cp /usr/share/grub/*.pf2  /boot/grub
sudo update-grub
