Luckily Linux is not Ubuntu and therefore other alternative still exist: XFCE (Xubuntu) is a very valid one which is likely to see its user-base vastly increased (at least +2 with Linux Torvalds and Me).
Ubuntu Unity has brilliant underlying ideas, among which the Global Applications Menu integrated in the top toolbar. Luckily, thanks to "aaronlewis1989" this is also available for XFCE 4.8. This is Linux flexibility: being free to keep the best ideas and dump everything not worth it. It's such a pity that someone in Canonical (Ubuntu) is trying to implement the same approach regular monopolistic companies do: forcing costumers to accept a compromise and surrender some right every time a new feature is implemented.
XFCE global app menu sources are available at this page and binaries (x86 32bit) at this page. A new PPA for ubuntu users has also been established here.
If you run a x86_64 (64bit) system you need to compile the source, which is a very easy job by the way!
Install a few dependencies first:
sudo apt-get install synaptic indicator-appmenu appmenu-gtk appmenu-qt appmenu-gtk3 firefox-globalmenu thunderbird-globalmenu xfce4-panel-dev libxfce4util-dev libindicator-dev libwnck-dev libxfconf-0 checkinstall
then unpack the tarball and open a terminal navigate inside the folder (if you have unpacked it in your home type)
cd xfce4-appmenu-plugin
now type
./configure --libexecdir=/usr/lib/xfce4-indicator-plugin/ --prefix=/usr --disable-debug
make
sudo make installor alternatively
sudo checkinstall --pkgname=xfce4-appmenu-plugin --pkgversion=0.25-betathen go in the folder binary/x86 and install the package
dpkg -i xfce4-appmenu-plugin_0.25-beta-1_i386.deb
log out, log in again and right click on your XFCE panel and add the Indicator Appmenu Plugin!
Enjoy your 20px extra vertical real estate!! :D
Should you want to remove it simply use the package manager or type
sudo apt-get remove xfce4-appmenu-plugin
Troubleshooting:
- Should you run into this error message:
The required package libxfce4panel-1.0 was not found on your system.
- If you cannot find the Indicator Appmenu Plugin applet among the available panel applets, please ensure you have typed:
./configure --libexecdir=/usr/lib/xfce4-indicator-plugin/ --prefix=/usrrather than simply
./configure
