Under the Advanced options in the second bootloader configuration screen, you can select a video mode from a drop down list. This is ignored when the grub2 configuration is written. If there is an existing video mode setting (vga=...) in the boot options, this appears in the "Append" string. I believe it is supposed to be extracted and used to set the default video mode selection.
Created attachment 9514 [details] Proposed fix This needs to be applied after the patch attached to bug 21263 (attachment 9511 [details]).
Adding to the mga5->mga6 upgrade tracker, because it affects people who choose to convert from grub to grub2 - the video mode setting is lost, which can lead to plymouth failing to display the splash screen with some video drivers.

commit f70da6dee2087dbcb26e1ae6e00c5ea859c0c787 Author: Martin Whitaker <mageia@...> Date: Mon Jul 24 23:07:38 2017 +0100 Fix drakboot video mode selection when using grub2 (mga#21246) The video mode needs to be extracted from and written back to the GRUB_CMDLINE_LINUX_DEFAULT parameter in /etc/defaults/grub2. This fix creates a new "default_vga" key in the $bootloader hash to hold the current selection. Using the existing "vga" key would cause the default video mode to be added to any bootloader entries that don't have a specific "vga" value, e.g. the "failsafe" entry. The $bootloader "vga" value doesn't appear to be set anywhere else, so may in fact be obsolete. --- Commit Link: http://gitweb.mageia.org/software/drakx/commit/?id=f70da6dee2087dbcb26e1ae6e00c5ea859c0c787

Tested in Virtual Box using GRUB2 The VGA=791 is appended if I choose 1024*768*16, after reboot, if I return to drakboot (using MCC), and choose the advanced options, the tool remebers the last selection (OK for ME) The vga=794 is appended if I choose the 1280*1024*16 This update is good to OK
