This tutorial should only be used if you are running Tectonicus on a machine without a discrete videocard, with an integrated one. Intel display adapters are integrated (into the south bridge of a chipset).
Typical Tectonicus error log for integrated graphics
If you have no discrete video card, the Tectonicus log will probably contain the following output:
Could not create pbuffer! (colour:24, alpha:8, depth:16, samples:0)
Exception while trying to create drawing surface!
Try specifying numSamples=0 to disable antialiasing
org.lwjgl.LWJGLException: No Pbuffer support

This means the PBuffer feature of LWJGL java library, which is used by Tectonicus, is not working correctly.
Instructions for GNU/Linux machines
Relevant to a Debian based distributions, such as Debian and Ubuntu.
- Install libgl1-mesa-swx11 package by running this command in the terminal:
sudo apt-get install libgl1-mesa-swx11
This will probably provoke a virtual package libgl1 conflict with libgl1-mesa-glx package, so you will be asked if it should be removed or not. libgl1-mesa-glx should be removed.
- Prepare your Tectonicus console command as usual, but set minecraftJar= and probably useBiomeColours=false if you are getting an error for that.
More information about console triggers can be found here.
Caution
It has been reported that hardware rendering after this package swapping becomes laggy, so it may be necessary to disable any desktop compositing effects.
