Gnome-Do 0.8.2 released – New features and plenty of improvements

A new version of Gnome-Do was released today – 0.8.2. However, don’t be deceived by the small change in version number, this new release contains plenty of new features as well as squashing quite a few bugs along the way. Here is a brief summary of some of the changes I’m aware of.

Docky ‘Intellihide’ Feature
Previously when using Docky at the bottom of the screen, you had two options. You could either have the dock open permanently or you could enable the auto-hide feature. Having the dock there permanently certainly facilitates speedy opening of programs but in reality, it is hardly ideal – what with it getting in the way of all your windows and not allowing you to click on anything at the bottom of the screen. The autohide option is probably the way most people went – but this means that the dock is never visible until you drag the mouse pointer down to the bottom of the screen – which makes opening programs using the dock rather cumbersome.

This contradiction has now been resolved with a new feature called ‘intellihide’. If selected, the dock will automatically hide itself when there are full screen programs open on the desktop or when windows are too near the bottom of the screen. However, Docky can still be accessed at all times by dragging the mouse down to the bottom of the desktop. If no programs are open on the desktop and nothing is blocking the bottom of the screen, Docky will pop back up again and stay at the bottom of your screen allowing you fast, easy access to your most used programs when you need them.

Docky Top and Bottom Orientation
Whilst previously Docky could only be placed at the bottom of your screen, you can now have your favourite dock floating around at the top of your screen now – giving you even more possibilities for desktop customisation.

Improved Flickr Uploading
The Flickr upload plugin now provides more feedback on upload progress. Unlike previously where there would simply be a Gnome-Do icon displayed in the system tray, the Flickr uploader now has it’s own window and tells you when the upload has completed successfully.

Better UI and Graphics Perfomance
Your mileage may vary depending on what hardware and drivers you are using but I have noticed that the dock animations seem much smoother than before. Furthermore, there are some lovely coloured lighting effects on dock icons for the application which is active in the current window. You can now also change the zoom and icon size settings with sliders rather than dragging “handles” on the dock itself.

Docklets
I’ve tried installing this feature with:

sudo apt-get install gnome-do-docklets

But it says that it can’t find this package or something along those lines. It sounds like an exciting feature but I’ll have to wait until I can get it working before I can provide more details. All I can find at the moment is information about a nifty looking Weather Docklet which is documented on the Do Wiki.

Apart from the things I mentioned above, there are now a lot of new plugins available for Gnome-Do and localisation is better than before – with most of the program and some plugins now available in other languages. There are probably plenty of other things that have so far gone unnoticed so please leave me a message in the comments if I missed anything important.

Nvidia 180 Driver + Compiz Redraw Problem Easy Fix (Ubuntu)

For a while I have been experiencing some GUI redraw problems in both Ubuntu Intrepid and Ubuntu Jaunty that have severly affected the user experience. For example, in Geany, a text editor, when scrolling, parts of the text would disappear or appear in the wrong place giving a very buggy glitchy feel. Likewise, when using gnome-terminal and Tilda (another terminal), the display would often not redraw or text would appear in the wrong place. Worst of all was Openoffice Writer and VLC – where buttons or parts of the interface would simply disappear only to reappear when you mouseover!

I am running the latest stable Nvidia driver (180) from the main repositories and am using Compiz as a window manager. It turns out that this is a common problem (see launchpad bug here) and there is now a workaround that is easily implemented. The bug is related to Compiz and Nvidia and not the applications themselves. Here is the fix:

First install compizconfig-settings-manager if it is not already installed.

sudo apt-get install compizconfig-settings-manager

Launch CompizConfig Settings Manager

System -> Preferences -> CompizConfig Settings Manager

Now navigate to the utility section and click on the workarounds plugin. Enable the “force syncronization between X and GLX” option.

That’s it. The changes should be made effective immediately and hopefully you should not see any more artifacts or slow redraws when using the aforementioned applications. Hopefully this can be fixed properly by Nvidia or the Compiz developers sometime but for now this fix will do just fine.

Install Nvidia Linux driver version 180 using apt-get

If you are experiencing poor graphics performance on your Ubuntu box – such as jerky scrolling in Firefox and sluggish 2D animations in applications such as cairo-dock and the ‘docky’ gnome-do, you may want to consider upgrading your nvidia drivers from nvidia-glx-177 or nvidia-glx-173 to the newer nvidia-glx-180 driver. Whilst this driver is not yet recommended by Ubuntu (and hence is not visible in Hardware Manager) it may well fix quite a lot of bugs you are experiencing and improve overall performance.

To install the drivers, simply fire up a terminal and enter the following command:

sudo apt-get install nvidia-glx-180 nvidia-180-modaliases

Once that is complete, reboot the computer and open up nvidia-settings in a terminal, it should now tell you that you are running the 180.* nvidia driver. Likewise, Hardware Manager should also tell you the same thing. If you experience any problems with the new driver, you should probably downgrade back to 177 or 173 until Ubuntu releases Jaunty Jackalope – but I haven’t run into any difficulties yet!
