Fabio's questions

I have just finished a succesfully upgrade from 10.04.4 to 12.04.1 on my remote server. After reboot, I have verified that it is still booting from the old kernel:

$ uname -a
Linux socrates 2.6.32-41-generic-pae #94-Ubuntu SMP Fri Jul 6 17:08:20 UTC 2012 i686 i686 i386 GNU/Linux

I have also run update-grub:

 $ sudo update-grub
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
Found kernel: /boot/vmlinuz-3.2.0-29-generic-pae
Found kernel: /boot/vmlinuz-2.6.32-41-generic-pae
Found GRUB 2: /boot/grub/core.img
Found kernel: /boot/memtest86+.bin
Updating /boot/grub/menu.lst ... done

But it is still booting from the old one... I have verified that I am still running grub Legacy:

   dpkg -l grub* | grep ii
ii  grub                                 0.97-29ubuntu66                     GRand Unified Bootloader (Legacy version)
ii  grub-common                          1.99-21ubuntu3.1                    GRand Unified Bootloader (common files)

Since at least a month, my 11.10-64bit PC doesn't shutdown anymore from the GUI. It simply freezes on plymouth screen. If I open gnome-terminal and type "sudo poweroff", it shuts down correctly.

This is very annoying. I don't have any relevant message in the logs. It simply stops at "The system will be halted"...but it doesn't power off.

I have instructed DejaDup to keep one-week of backup files. Now it is passed more than a month and my backup storage is fed up with old backups. Is there a way to instruct DejaDup to delete old backups without reaching the storage limit? Can I detele them manually?

I know how the Unity dock works and I like it. But I need a fast tool to list all the opened windows instead of looking at the dock and find out which of those have a backlight arrow sign... Is it possible?

I have just installed ubuntu 11.04 on my ACER 3810T.

Unity is showing only few launchers in the sidebar and the "Applications" launcher is not there. More, if I press Alt-F", not windows (lens) comes up.

Where should I troubleshoot this?

Thanks
