Here are the messages after I set the filter to none and disable "Filter Hints without Source Position":

The line before "Error while linking" is:
/usr/bin/ld: cannot find -lGL

What is it? And what should I do to fix it?

In my /home/handoko/.lazarus/bin/link.res I found these:

So lGL is a library. I checked using Synaptic Package Manager, lGL can't be found in the repository of Ubuntu 18.04 default installation.

Still looking for solution ...

sudo apt-get install libgl1-mesa-dev

libgl1-mesa-dev was already installed.

Because Ubuntu 18.04 (maybe also other linuxes) drops support for NVidia driver 304, now I'm using Nouveau driver. It's working good, I can run Lulu's Fire & Wire game (Game Contest 2018) using this open source driver.

Could you think this is the cause of the problem.

Previously before I upgraded my Ubuntu and Lazarus, I was using NVidia driver version 304. I had no such problem. Ubuntu 18.04 only provides Nouveau (open source), NVidia 340 and 390 drivers. The version 340 and 390 show only a blank screen and stop when starting the Ubuntu.

I googled the web, I saw people are complaining the missing NVidia 304 support on Ubuntu 18.04 and lGL library on Ubuntu 18.04.

Yes. Maybe you should post a question on the Ubuntu forum and ask the guys if it's possible to install those libraries under 18.4.
