August 2, 20187 yr Calling all Linux geeks...I know there are lots here. I am on the very last step of turning an x86 system into a Retropie appliance. It is essentially Ubuntu Server 17.10.1 x64 with Openbox as the window manager and Retropie installed (yes...you can run the Retropie setup script on Ubuntu). I borrowed a lot of work that was already done but then wanted to hide all of the background (gnome terminal window, mouse pointer, etc.). Normally coming in and out of a game you would see the mouse pointer and a the gray gnome terminal window with a light blue title bar. Here is the *almost* finished product if anyone is interested (I will write-up a full how-to): Where I am stuck is hiding the usual Ubuntu boot dialog. I really want to use a fancier splash screen using Plymouth, but, I can't get even get the standard splash screens to work. I was hoping it would be as easy as turning it back on in the grub config (shown below) and updating grub... GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=2 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="splash" GRUB_CMDLINE_LINUX="" but it hangs at the following: And then eventually this... I have tried on a VM in unRAID and two different physical hardware. I even tried Ubuntu Server 16.04.4 with the same result. Can anyone help?!?!?!
August 3, 20187 yr Author I'm having much better luck on 18.04. However, in order for the splash screen to work, I have to append the GRUB_CMDLINE_LINUX line. Appending the GRUB_CMDLINE_LINUX_DEFAULT has no impact (at least not for me). If this works satisfactorily, I run through my entire Retropie setup process on 18.04. John
