After the upgrade to Ubuntu 11.04 I noticed that my HTPC box wouldn’t automatically reboot after a hard reset. I always had to connect a keyboard and press the enter button to resume booting. Kind of an unwanted situation for a box that stands in the living room. So I went through the grub.cfg file to see what needs to be changed. Here is the Ubuntu howto:
First open the /etc/grub.d/header file (you need to use sudo, so you can save it) and look for the following lines:
make_timeout ()
{
cat < < EOF
if [ "\${recordfail}" = 1 ]; then
set timeout=-1
else
set timeout=${2}
fi
EOF
}
Then change the line "set timeout=-1" to some other, positive value, like: "set timeout=10". The result should look like this:
make_timeout ()
{
cat < < EOF
if [ "\${recordfail}" = 1 ]; then
set timeout=10
else
set timeout=${2}
fi
EOF
}
Now the grub.cfg template is updated, the only thing left is to execute an update of the real grub.cfg.
sudo update-grub2
This way the modifications remain in the system, even when new kernels are updated.
