Ubuntu – How to Clean Up Ubuntu Grub Boot Menu After Upgrades

bootUbuntu

Recently I have installed Ubuntu 9.10 – the Karmic Koala – released in October 2009 .I upgraded using update manager many times. So each time I update it is adding one menu in boot screen like recovery mode. I have windows OS also. Right now in booting time it is listing around 10 bootmenu's. Windows OS goes to last line of the menu . How can I clear all the boot menu's except windows and ubuntu latest vesion?

Go into the synaptic package manager, and scroll down until you find linux-image-*

You can safely remove them all, except the one you booted from. (You can find that out by running 'uname -r' from the command line.

Also running 'sudo apt-get autoremove --purge' from the command line may detect the 'old' ones and automatically remove them.

Your APIC is borked. You'll need to use the noapic option. See here for a forum posting regarding this. Don't fret, it doesn't mean that the hardware is bad, just that the BIOS didn't configure it in a state that was suitable for booting a kernel. You should also look around for a BIOS update and see if that helps.

Ubuntu – Getty flooding syslog after kernel upgrade with “cannot open as standard input”

I had this same issue with a Rackspace-hosted server that I recently upgraded to Ubuntu 12.04 LTS. My /var/log/auth.log file was getting flooded with

May 13 12:50:40 foo getty[1796]: /dev/tty2: cannot open as standard input: No such device
May 13 12:50:51 foo getty[1798]: /dev/tty3: cannot open as standard input: No such device
May 13 12:50:51 foo getty[1797]: /dev/tty4: cannot open as standard input: No such device
May 13 12:50:52 foo getty[1800]: /dev/tty5: cannot open as standard input: No such device
May 13 12:50:52 foo getty[1799]: /dev/tty6: cannot open as standard input: No such device

All I did was remove (after backing up) the following files:

/etc/init/tty[2-6].conf

After I rebooted the problem was solved. No more noise in the log file and the Rackspace console still works, although with only one virtual terminal. (I never use virtual terminals on the console anyway.)
