Installing Lazarus 1.8.4 on Ubuntu 18.04
Handoko:
Problem solved, now my Lazarus 1.8.4 seems to work correctly.
Not sure which one was the 'real' solution, but I have done these:
Because IGL is a library related with OpenGL, I use Synaptic Package Manager to reinstall items that related with OpenGL. I use Synaptic to find items with keyword "libGL". Then right-clicked on them and selected "Mark for reinstallation". (This is what I like about Synaptic, you can reinstall items without need the dependent libs/programs to be removed. AFAIK, I can't do it using Terminal).
Also, on the Lazarus IDE, I marked the OpenGL related packages to uninstall. FYI, I previously had LazOpenGL Context, BGRABitmap, Castle Game Engine installed on Lazarus 1.8.2.
After I done those 2 things above, I rebuilt my Lazarus 1.8.4. Everything went smoothly. And later I reinstalled back LazOpenGL Context, BGRABitmap, Castle Game Engine packages.
So far my Lazarus 1.8.4 now works without any issue.

I think it is not "IGL" but "lGL" (lowercase L). So sudo apt-get install lGL
should do the trick, and the only "i" is in "install".
Handoko:
Oh my fault, if I mentioned IGL. It should be lGL.
I got "Unable to locate package lGL" if I type sudo apt-get install lGL on my Ubuntu 18.04 Terminal.
howardpc:
Sorry that should be ... install libGL
Handoko:
libGL was already installed. Thank you for the suggestion, now my Lazarus is working correctly.
