Follow-up Comment #5, bug #49814 (project grub):

Good catch. I won't claim to fully understand this code, but as far as I can
tell in grub_video_set_mode()
- if we have "keep" we simply return keeping current adapter
- if we have graphic mode, we reinitialize adapter
in both cases we later reset current page in
grub_video_fb_get_info_and_fini(). But if we have test mode then
- we shut down current video adapter *without* changing current page, and
probably reset it to NULL
it means we are left with whatever was set before.
May be we need wrapper around ->fini() method that resets current page (moving
code from grub_video_fb_get_info_and_fini()).
