MATLAB: Am I unable to disable font antialiasing in Linux with Gnome in MATLAB 7.5 (R2007b)

MATLAB

It turns out that Gnome differs from other Linux window managers in that it makes Java aware of the system antialiasing settings. As a result, Java picks this up automatically and behaves as it does on Windows, which is to say, the application obeys the system setting.

However, other Linux window managers do not supply Java with the antialiasing, which is why the checkbox exists, so that you can manually turn on antialiasing.

So on Gnome, the behavior is as follows:

 Gnome setting          MATLAB setting         MATLAB result
 ------------------------------------------------------------
 Monochrome (No AA)     No AA                  No AA
 Monochrome (No AA)     AA                       AA
 LCD AA                          No AA                  AA
 LCD AA                          AA                       AA

To allow for turning off font antialiasing, you can create a file named "java.opts" in the $MATLABROOT\bin\glnxa64 directory where $MATLABROOT is the MATLAB root directory on your machine, as returned by typing

matlabroot

at the MATLAB Command Prompt.

containing the following line:

-Dawt.useSystemAAFontSettings=false

That, as well as leaving the MATLAB checkbox deselected, should result in MATLAB alone being non-antialiased.

MATLAB: Do I receive the error, “libstdc++.so.6: version `GLIBCXX_3.4.22′ not found” when trying to start MATLAB on Ubuntu 18.04

The libstdc++ library shipped with Ubuntu 18.04 may be older and may not contain the required GLIBCXX version that MATLAB requires.

To resolve this issue you may upgrade the libstdc++ libraries by running the following command as they appear:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9
sudo apt-get upgrade libstdc++6

Use MATLAB's libraries by setting the environment variable:

export LD_LIBRARY_PATH=/usr/local/MATLAB/R2018b/sys/os/glnxa64

Then attempt to open MATLAB again.

MATLAB: Do the desktop fonts look difficult to read when Windows ClearType antialiasing is enabled

This enhancement has been incorporated in Release 2009b (R2009b). For previous product releases, read below for any possible workarounds:

This is due to a problem in Java's sub-pixel, antialiasing, font-rendering algorithm. The workaround is to create a java.opts file and place the following line in the file:

 -Dawt.useSystemAAFontSettings=false

Save the java.opts file to matlabroot\bin\win32, where matlabroot is the root directory in which MATLAB is installed. You can determine this location by executing the command

matlabroot
 in the Command Window.

Restart MATLAB. MATLAB should no longer employ antialiasing and the fonts should be clear.
