Public bug reported:
Binary package hint: grub2
On my Aspire one AOA 110L if the line
#GRUB_TERMINAL=console
in /etc/default/grub is commented (which is the default) in about 60% of the
times th screen stays black after booting.
The background light of the screen still goes on and off at every video mode
change. And I am able to open a terminal whenever I want, to reboot the
computer and even to play a ogg/vorbis file - so the computer basically works.
But the screen stays black and blank.
In another 30% of the times grub-pc hangs completely without even
loading the kernel or displaying the boot menu if I press the Shift key
during boot. Sometimes in this case the display fades in the way that
indicates that the light is on - but it is no more accessed by the
graphics card.
If I uncomment the
GRUB_TERMINAL=console
and do a
sudo update-grub
afterwards the computer is up in 12 seconds and runs fine.
This problem is relatively new (about 2-3 weeks) and reproducible both
with plymouth-theme-ubuntu-logo and plymouth-theme-ubuntu-text.
Uninstalling plymouth at all seems no longer to be supported on natty.
