10.04 Lucid Lynx and 10.10 Maverick Meerkat are almost identical in the looks department – both used the old boring (no kidding) Gnome interface. They even have the same cat-sounding names. If you don’t know your Ubuntu very well you won’t spot the difference easily. (clue: wallpaper)
11.04 Natty Narwhal and 11.10 Oneiric Ocelot are both using the new Unity shell and are easier to identify through not-too-subtle differences.
The window switching for same apps on Unity – starting with Ubuntu 11.04 Natty Narwhal – is confusing. It is easier to determine windows of different applications with the use of Alt+Tab combo where there is an overlay icon shown by default. When switching between windows of the same application it’s hard to determine which one is which.
This is what I have observed. When switching between windows strictly of the same application through the Unity launcher, this is what appears to happen.
Ever got tired of Nautilus showing all disks or partitions present on your system?
While it helps you access these devices quickly, sometimes it becomes an eye sore when there are too many disks with long funny names, and add to that your external disks, flash and CD/DVD drives – the list becomes confusingly long.

If I remember correctly, Ubuntu Lucid Lynx (10.04) and Maverick Meerkat (10.10) lacked the concept of a “control center.” Although the app is readily available, Ubuntu did not make use of it “visibly.” The control center remained hidden among the multitude of apps that comes pre-installed with the operating system. Natty Narwhal has the Control Center (a.k.a System Settings) prominently right below Shutdown in case you’ve missed it for some reason.
The default Unity launcher quicklist for Firefox could certainly do with a few additional options. It’s easy to add a few more.
This tip I got from AskUbuntu. There are more quicklist tips available and you can read it at this page – http://askubuntu.com/questions/35488/list-of-custom-launchers-quicklists-for-unity. I only wanted to add a few more useful options than the ones given.
A bug or what? While I was tinkering around with the gksu ‘force-grab’ functionality with the Ubuntu Software Center (USC) I realized that it was updating the cache every time I entered a wrong password.
Although the Software Sources window did not come out, as expected, because of the wrong password, nothing else should have happened except for an alert that the password was incorrect. Unfortunately, gksu does not appear to have that functionality by default. It is a hit or miss event and it will not repeat or warn the user if the process failed. It will simply terminate. (Try ‘gksu geditor’ on a terminal, or Alt + F2, and type in the wrong password.)
I’m using this appindicator on Ubuntu 11.04 that has an icon that doesn’t blend too well with the Radiance theme. Although the icon is monchrome-ish, I think it was intended originally for the Ambiance theme. On the panel it looked the odd-man-out because it had more white color than black.
If you are using the patched version of Notify-OSD* from Leolik’s PPA and using Notify OSD Configuration GUI** of AmandeepGrewal to change the look of the notification bubble, chances are you may also have edited the .notify-osd file by hand to include either or both of the following: bubble-prevent-fade and bubble-close-on-click. These two options are not included in the GUI.
What you should be aware of is that the GUI will overwrite any and all changes to the the .notify-osd file. Using ‘Save Theme’ will not include whatever changes were made outside of the GUI.
The default scrollbars for applications that don’t support the overlay scrollbar are too fat and ugly. They could certainly use a little workout to shave off a few excess weight. If you can’t wait for another six months for Ubuntu to roll-out support of the overlay scrollbars to all applications like me, well, let us at least force these obese scrollbars to become thinner.
HOW? Feed them a veggie-only diet? Perhaps. Workout at the gym? Not really. How about we edit the gtkrc file? YES!
(1) The Unity launcher appears to look better when the backlight is set to toggle. That is, when an application (app) is running its icon backlight is On and turned Off when it is not. This makes the running app more distinct against the non-running ones.
