Improved font rendering in lightweight desktop environments

When using lightweight desktop environments or window managers without desktop environments, sometimes font rendering does not look as good as in GNOME or KDE.

It is possible to improve font rendering by creating the file ~/.fonts.conf and inserting the following content.

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
       <match target="font" >
              <edit mode="assign" name="rgba" >
                     <const>rgb</const>
              </edit>
       </match>
       <match target="font" >
              <edit mode="assign" name="hinting">
                     <bool>true</bool>
              </edit>
       </match>
       <match target="font" >
               <edit mode="assign" name="hintstyle">
               <const>hintmedium</const>
               </edit>
       </match>
</fontconfig>

The degree of subpixel hinting can be configured by using either hintslight, hintmedium or hintfull for the last parameter.

Subversion diff and patch

Store the (versioned!!) local changes of your working tree to a file localchanges.diff in your home directory:

svn diff > ~/localchanges.diff

Restore the changes back to your tree:

patch -p0 -i ~/localchanges.diff

Changing boot order Windows/Linux in GRUB2

By default, the installation provides a GRUB 2 that is configured to first probe for Linux OSs and then only for other OSs. A simple yet quite robust way of changing the order to Windows first and then Linux is the following:

Open a terminal and issue the following commands:


cd /etc/grub.d

sudo mv 30_os-prober 09_os-prober

sudo update-grub2

These commands will make sure thatr the os-prober script (which probes for other OSs, such as Windows) is executed before the script that probes for Linux OSs when automatically building the grub.cfg file.

Adding and removing kernel modules to/from boot time

I know, this is a simple one, but I easily keep forgetting:

To (quickly and easily) blacklist modules from loading, edit /etc/modprobe.d/blacklist, add a line similar to:

blacklist myModule

To add modules to startup, edit /etc/modules. Just add the name of the module on a new line.
