Ubuntu GNOME – Fix Grey Screen and Slow Boot


On every boot up I get this:

grey screen

For about 10 seconds (or more) before the "normal" Ubuntu Gnome loading screen and the login screen comes up.

I've read some questions and a bug report about this already, but this problem was dismissed as a minor inconvenience or there were no real solutions (that worked for me). For me, this problem leads to an unacceptable slow boot compared to Ubuntu (Unity) or Windows.

Does anybody know how to fix this or is this a "feature" of Ubuntu Gnome and not a bug?

Best Answer

CLI method

sudo nano /etc/default/grub


sudo update-grub

GUI method (mostly)

Install Grub Customizer

To do that, Open terminal by pressing Ctrl+alt+T, and enter the following commands one by one

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

After installing it open it by this command


it might ask you for your password

  1. Go to General Settings tab
  2. Check Show menu option under visibility (if you want Grub Screen to be visible)
  3. Change the value of Boot default entry after to be less than 10 Seconds (I've made it 1 Second)
  4. After you're done click on Save button in upper left corner

Try to reboot your system now, and see if the problem is gone

Grub Customizer windowTheme might not look like this
