Hi, thank you for your response. We installed VirtualGL 2.6.5 on Ubuntu 20.04 and are still getting this error " [VGL] ERROR: Could not open display :0 " What error logs/install logs should be looking for possible errors ?
On prior release, we solved this by attaching a monitor, but we have a monitor attached and are still getting this error for this release ? Emmanuel, can you please confirm your re-run vglserver_config ? $ lsb_release -a No LSB modules are available.
