I found the fix from here. The root cause is that the “rubypython” gem was looking for the python library file from a path which was incorrect on the ubuntu-14.04(AMD64) environment. So the fix is simple: create sybolic links of the library files where the “rubypython” gem is comfortable to work:
$ cd /usr/lib # For ubuntu 14.04(AMD64/x86_64) $ sudo ln -s /usr/lib/python2.7/config-x86_64-linux-gnu/libpython2.7.so $ sudo ln -s /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 # For ubuntu 14.04(x86) sudo ln -s /usr/lib/python2.7/config-i386-linux-gnu/libpython2.7.so sudo ln -s /usr/lib/i386-linux-gnu/libpython2.7.so.1.0
Another possibility is that the needed Python version is not installed. In my case when building the Octopress posts on Ubuntu 16.04 Xenial, I meet the same issue but the Python lib files are in the right place, the roor cause is that: the Python version “2.7.10” is not installed. Install it by using “pyenv install 2.7.10” then it works.
Eclipse menu is disappeared
“Eclipse(Kepler SR2)” cannot show the menu under Ubuntu 14.04. The solution was found from here:
1 2 3 4 5 6
# Add the following line at the end of "~/.local/share/applications/alacarte-made.desktop(or any name you're sure indicating eclipse)": X-Ayatana-Desktop-Shortcuts=NewWindow [NewWindow Shortcut Group] Name=New Window Exec=env UBUNTU_MENUPROXY= eclipse TargetEnvironment=Unity
RabbitVCS right-click menu is disappeared
The solution is found from here. This is actually 2 problems:
The python lib files missing problem as “octopress cannot generate pages”;
The “/usr/share/nautilus-python/extensions/RabbitVCS.py” file should be updated as the one from here.
Default Chinese font
The default Chinese font of Ubuntu 14.04 is Song while I prefer WQY(文泉驿). Install the WQY fonts and the default Chinese font of Ubuntu will be changed to WQY automatically.
1 2 3 4 5 6 7
$ apt-cache search wqy fonts-wqy-microhei - Sans-serif style CJK font derived from Droid fonts-wqy-zenhei - "WenQuanYi Zen Hei" A Hei-Ti Style (sans-serif) Chinese font ttf-wqy-microhei - transitional dummy package ttf-wqy-zenhei - transitional dummy package xfonts-wqy - WenQuanYi Bitmap Song CJK font for X $ sudo apt-get install fonts-wqy-microhei fonts-wqy-zenhei ttf-wqy-microhei ttf-wqy-zenhei xfonts-wqy
And here is a list of the packages I want to install at the first place after install a new Ubuntu environment besides the WQY fonts:

GUI(Compiz) performance issue
I experienced very pool GUI performance issue. Here is the fix(from here and here):
Run the following command to check if the 3D acceleration is enabled or not:
1 2 3 4 5
/usr/lib/nux/unity_support_test -p # If the result is as follows: Not software rendered: no # That means the 3D acceleration is NOT enabled which shoulb be. # Enable the 3D acceleration at "Virtualbox -> selected VM -> settings -> Display -> Enable 3d Acceleration".
After enabling the 3D acceleration, the performance issue should be resolved. If you want a better performance, do the next step as well.
1 2 3
# Install "compizconfig-settings-manager": sudo apt-get install compizconfig-settings-manager # Run it from dash, go to "OpenGL", select "Fast" from the "Texture Filter" dropdown list.

Today I found this problem happened again, I guess the reason is I updated the kernel version yesterday. And I confirm my guess and get the solution from here. I also experienced “clipboard copy problem” and “screen resolution problem” which are also resolved after the following “VirtualBox additions” reinstallation.
I’ve had the same problem since Unity came out, here is the solution that always works for me.
1. Enable 3D acceleration in VirtualBox for the machine
2. Provide adequate video memory
3. Boot the Ubuntu guest
4. ensure kernel headers is installed for your running kernel
5. sudo apt-get install build-essential linux-headers-$(uname -r)
6. Mount vbox additions
7. Install Guest Additions, it should autostart, if not run it from a sudo command prompt
8. sudo ./VBoxLinuxAdditions.run
9. Ensure that the word 'vboxvideo' appears on a line on it's own in /etc/modules
11. Test with sudo /usr/lib/nux/unity_support_test -p
This ensures the vbox video driver is built correctly and installed for your current running kernel.
Note, if you ever do an apt-get dist-upgrade you will need to repeat this process as your kernel version might change.
