libgl error pic id driver null – ros2 turtlesim

Hi everyone,

I’m currently following the ros2 turtlesim tutorial with Ubuntu on an M1 Mac with Parallels and Ubuntu. Unfortunately, I hit a ‘device not found’ when trying to start the control node.

A bit of Googling revealed that 3D acceleration might not be enabled. To fix this, all you need to do is the following:

  • Open settings in Parallels (the cog icon)
  • Click the Hardware tab up the top
  • Click Graphics on the left hand side
  • Click Advanced
  • Tick Enable 3D Acceleration

You’ll need to restart the VM, but once that’s done the libgl error should be resolved!

If this doesn’t work, there are a few other things you can check. First, double check that you’ve installed (or re-installed) Parallels Tools.

I have also found that the 3D Acceleration seems to randomly break or reset itself. If it hasn’t automatically unchecked itself, I’ve occasionally had to do the following to get it working again:

  • Stop the VM
  • Disable 3D Acceleration
  • Start the VM
  • Stop the VM
  • Enable 3D Acceleration
  • Start the VM

Another options mentioned in this thread is to set the following environment variable before starting rviz or gazebo: 

export LIBGL_ALWAYS_SOFTWARE=1

The Repository is not Signed – Ubuntu ros2 installation

Hi everyone,

I’m currently installing ros2 on Ubuntu (with Parallels) and ran into the following error:

I was following the official tutorial so I was little surprised to see this crop up. What I hadn’t realised was that I’d missed an error in the output dump while running sudo apt update:

sudo: curl: command not found

This was a clean install of Ubuntu and I hadn’t yet installed curl. Luckily, this is a simple fix:

sudo apt update
sudo apt install curl
