    I don't think Grub-customizer will work, because everytime the resolution is auto detected and updated on the grub file. Unless, that auto detection and updation is stopped, nothing can be done.

    Edit  /etc/default/grub
    Add a GRUB_GFXMODE=1280x720 line (or choose a more convenient resolution)
    save the file and run sudo update-grub

    Done it several times. No use, it just reverts back to the full resolution.

    My 2nd guess, while not tested...:

    Edit /usr/share/dde-api/data/grub-themes/deepin/theme.txt.tpl (This is mentionned in /boot/grub/themes/deepin/theme.txt)
    Add lines
    screenWidth:1280
    screenHeight:720
    just under the # Global properties comment (1st line)

    the run sudo update-grub -OR- change the grub wallpaper via deepin-control-center (System information: / Boot menu) to force a new grub generation

    Hope this helps, let me know,.

    Found a temporary solution. I commented the file content in here
    /usr/share/dbus-1/system-services/com.deepin.daemon.Grub2.service
    .
    Now I'm able to change the resolution, but the grub manager in control center gets disabled if i do this. Therefore you won't be able to change background wallpaper, as long as it is commented.
