Using the same swap space for different linux installations

I  want to upgrade my server to 11.04 now I have tried it on my laptop. However as this can take some time until I have all of the services configured I decided to make some space free and install the 11.04 server on a separate partition.

I notice that the installation automatically reserves some swap space for the new Ubuntu installation, even though there is an existing linux swap partition. This seems wasteful to me so I looked up the UUID for the existing swap space using

suso blkid

or by mounting the other linux on /mnt with for example

sudo mount /dev/sda1/ /mnt

 and looking under /mnt/etc/fstab for the UUID for the swap

The replace the swap UUID in /etc/fstab with the existing one.

You  can then use GParted to utilize the new swap space for something else.

Nautilus in Ubuntu 11.04 Natty Narwhal

I have had a couple of issues with Nautilus since upgrading the Ubuntu 11.04.

Where is the menu bar? Until I got used to Unity I didn’t realize that the menu for each application with focus is in the desktop menu bar. Its pretty neat when you get used to it.

Shortcuts. Because of the issue above I couldn’t find hidden files until I remembered Control-h which I haven’t used in years. This got me to thinking of the other shortcuts so I made a short list and posted it here.

Location Bar. I prefer a text based location bar because I like to cut and paste from it. Here is how to make a text based location bar the default.

Nautilus Location Bar

I have always preferred to use the text based location bar in Nautilus as it is useful for cutting and pasting into other applications etc. In earlier versions there was a button to switch from the breadcrumb view to the text based view but this button is missing in Natty Narwhal. You can switch to the text based view with Control-l or select Go -> location but the next time you open a window the breadcrumb view is back.

To permanently have a text based location bar go to a terminal and type:

gconf-editor 

In the editor click on apps in the left hand column and then select nautilus and preferences. Check the box at the side of always_use_location_entry in the right hand box.

That’s it.

Nautilus keyboard shortcuts

I have recently installed Ubuntu 11.04 on my laptop and until I got used to Unity I couldn’t find the menu bar for the nautilus window. I found out later that the menu for the application in focus appears in the desktop menu bar. However I urgently needed to find a hidden file and I half remembered that the keyboard shortcut was Control-h. That worked and so I started looking up other keyboard shortcuts and have put them together in a list below. I hope they are useful to someone.
