test grub2 themes from prompt

[nwtmg]

Using v6 4.14.65-desktop-1.mga6 . Upgraded to grub2 and installed some themes. It seems that the only way to test the theme is to reboot. Is there an application for testing grub2 themes from the prompt. I thought that perhaps I could dynamically create a bootable grub2 iso using grub2-mkimage or grub2-mkstandalone but no luck. Thanks.

Have a look at https://github.com/hartwork/grub2-theme-preview and maybe https://lists.gnu.org/archive/html/help ... 00021.html

Thanks for the software. Downloaded and installed. Receiving the following error. I know this is not supported software. All help will be appreciated. I believe I have all the dependencies installed.

Where has the python module grub2_theme_preview.cli been installed on your box ?

I appreciate your time with this problem. Located part of the problem. The module grub2_theme_preview.cli was installed in write protected directory /usr/lib/python2.7/site-packages
Made directory and all files read and execute which solved the initial problem. When I start with grub2-theme-preview and pass theme location I now get the error,

ERROR: Command "grub-mkrescue" of Grub 2.x not found

Since I am using grub2 why is grub-rescue being used. Will continue to research. Should I mark this as solved.

The GRUB developers consider GRUB2 to simply be the latest version of GRUB, so use grub- as a prefix for all commands. Some distributions do the same, but others, including Mageia, change this to grub2-. A quick peek at the grub2-theme-preview source code shows you should be able to solve this by running

Code: Select all

grub2-theme-preview --grub2-mkrescue grub2-mkrescue

or just edit grub2-theme-preview and change the default value on line 207.
