2014-11-11:Failure in faking Xinerama

Why to split my screen to two workspace

My desktop computer has a big 16:9 screen, and I'm finding it hard to fully utilize it during the 95% of the time that I'm coding and reading .
I'd like to set it up as a kind of virtual dual screen by splitting the physical screen into two workspace.
I know I could arrange my windows manually, but I'd like to be able to maximize a window and have it only consume half the monitor.

Brife introduction to Fake Xinerama

Fake Xinerama is a replacement libXinerama library that instead of querying the XServer reads ~/.fakexinerama and provides fake information about Xinerama screens based on this file. It can be used to fake a Xinerama setup ever on computers with just one monitor or to fake Xinerama setup other than one specified in the XServer configuration (e.g. making one screen smaller whern using two same screen). It's probably only useful for developers.

Following is exactly how I made it work

• Download fakexinerama.c from Fake Xinerama site
• Add X11 lib to local library

sudo apt-get install xorg-dev

• Produce libXinerama.so.1.0.0

gcc -02 -Wall fakexinerama.c -fPIC -o libXinerama.so.1.0.0 -shared

• backup original libXinerama.so.1.0.0
  Path: /usr/lib/x86-64.../libXinerama.so.1.0.0
• Override the original libXinerama file by one you produced

sudo nautilus

or

sudo copy  ../*path*/libXinerama.so.1.0.0    /usr/lib/x86-64../

• New .fakexinerama file in home

vim .fakexinerama
2
0 0 1080 1080
1080 0 840 1080

• Log out and back in

  Result

  It works in Ubuntu-unity -14.04. However, the second title bar covers the first tible bar when I opened two windows and maximize them. I can't select the right window by clicking title bar one time, and it made me mad.
  It can't work in Ubuntu-gnome-14.04 and later version. After changing the .fakexinerama file , nothing changes in desktop.

  Reasons

• The information post in 2012 may be out of date.

• The version of ubuntu-gnome is too late.
