Package: grub2
Version: 2.00-22
Severity: normal
Dear Maintainer,
=
When my system is connected to a monitor with both a DVI cable and a dislayport
cable,
the system boots fine and after the BIOS screen I see the grub menu, can select
the linux
kernel to use and it boots without issue.
However, if the system is connected to the monitor with only the displayport
cable but no DVI,
I still see the system BIOS screen after powering up, but then the grub menu no
longer appears
and the system does not boot. I verified this by checking
/var/log/{syslog,messages,boot} after
rebooting with the DVI cable inserted.
If the system is connected to the monitor using only an HDMI cable, then again
I see the BIOS
screens, the GRUB menu is not visible but the system does boot and I can login
via ssh.
It seems this issue is restricted to using a displayport cable and grub, as
even the default
kernel in grub.cfg was not booted in this case, although it did boot when using
only HDMI.
[The system boots into a console without starting X and the console is not
visible if the
monitor input is either displayport or HDMI.]
Here is the /etc/default/grub contents even though grub.cfg is attached as well
# If you change this file, run 'update-grub' afterwards to update
