Bug Description
Binary package hint: grub-pc
Not a big deal for me, but I thought I should report this nonetheless:
If the following line is commented out in /etc/default/grub:
#GRUB_TERMINAL=
my system rarely (Tried to start the system 30 of which it happened 3 times) hangs prior to loading the kernel. Note that around the begining of December 2010 there was a kernel bug as well that could lead to a black screen *after* the kernel was loaded (Bug #683775). To make sure the kernel really doesn't load I repeated this test starting my computer (A acer aspire an A110L) with the shift key pressed. About every tenth time the computer hung instead of displaying a boot menu. Sometimes the screen stays blank except of a blinking cursor, sometimes it just stays blank (but the backlight is on) - and one time the display faded in a way that seems to indicate that the LCD matrix is no more accessed by the graphics card.
Since this behavior and Bug #683775 seem to have occoured at roughly the same time they might be somehow related. But since one is a kernel bug and the other occours prior to loading the kernel chances might be low.
My graphics card identifies itselves as follows:
*-display:0
bus info: pci@0000:00:02.0
width: 32 bits
clock: 33MHz
*-display:1 UNCLAIMED
bus info: pci@0000:00:02.1
width: 32 bits
clock: 33MHz
Kind regards,
Gunter.

Changed in grub2 (Ubuntu): | |
status: | New → Confirmed |
Today I seem to have encountered the problem even if the line
GRUB_TERMINAL= console
of the file /etc/default/grub wasn't commented out and even if I ran
sudo update-grub
after making this change -which seems to indicate that it might not be a graphics-related problem after all.
Can anybody confirm this?
