I'm using Intel HD Graphics as graphics card and I'm trying to open an OpenGL program, but, when I try to run it, I have the following error: OpenGL GLX extension not supported by display ':0.0'

Then, I tried to run glxinfo, then I had the:

Error: couldn't find RGB GLX visual or fbconfig ubuntu 12.04 error.

How can I fix this error from not happening again?

  • this seems to be a bug bugs.launchpad.net/ubuntu/+source/mesa/+bug/1278168 – JoKeR Jun 3 '14 at 3:37

To solve my problem I had to enter the following commands:

sudo apt-get remove --purge xserver-xorg

sudo apt-get install xserver-xorg

sudo dpkg-reconfigure xserver-xorg

And then: sudo reboot

But I think that if you on pure text mode, you don't need to reboot your computer, but you would have to do sudo /etc/init.d/gdm stop before you type the commands I mentioned above and, after typing then, you will have to use sudo /etc/init.d/gdm start to start the graphic interface again.

  • This works for me. THX! – Michal Przybylowicz Jan 20 '15 at 0:56
  • Purging also removed ubuntu-desktop, ubuntustudio-desktop and xorg package. Recording here for @snafu after reboot. – anatoly techtonik Jan 7 '16 at 14:51

    Nah, reinstalling xserver-xorg didn't help. – anatoly techtonik Jan 7 '16 at 14:54
  • Worked for me, HP Pavilion 15. Thank you! – Mapsy Mar 2 '17 at 20:28
  • Didn't have to do the --purge to get it working on my Lenovo laptop with an NVIDIA GeForce 920M card. I thought this issue was connected to my graphics drivers that are not being utilised properly, but thanks to your suggestion I know that it isn't. – user1953384 Jul 6 '17 at 14:07
