A few problems that I experienced after the upgrade were:
- Restricted drivers manager not working. It said something like this:
You need to install the package linux-restricted-modules-* for this program to work.Solution: Install the restricted module, e.g.
apt-get install linux-restricted-modules-2.6.22-14-generic
- Couldn't turn on Compiz effects via System -> Preferences -> Appearance -> Visual Effects. It said something like:
Solution: Turn on "Composite" in /etc/X11/xorg.conf, i.e.
Option "Composite" "1"
However, before that, you have to install the GL based X server, i.e.
apt-get install xserver-xgl
Then, restart your X server (ALT + CTRL + Backspace) after you have made configuration changes.
- IDE and Java applications such as IntelliJ and Netbeans were broken with blank swing interface. I noticed that the menus were still working when I moved my mouse over them.
Solution: Set AWT_TOOLKIT to MToolkit, for instance, add this entry to /etc/profile:
export AWT_TOOLKIT="MToolkit"Then, reload the profile (source <profile>) and restart your IDE.
To find out what can Compiz effects do, please take a look at this Youtube video. I noticed and managed to discover some newly added effects:
- Shadow effects
- Maximize and Minimize effects
- Blinking/fading effects caused by error/alert, e.g. backspace on an empty text box in Pidgin; filling in invalid phrase in Firefox search box;
- Wobbly window effects while it's dragged
- Transparent effects (use ALT + Wheel Scroll on a window)
- ALT + Tab with real-time snapshots
- M$ + E to choose desktops
- M$ + Wheel Scroll to zoom
- M$ + Right Click to zoom in once
