Understanding glxinfo error

Question

My env is Ubuntu 18.04, headless server.

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.3 LTS
Release:    18.04
Codename:   bionic

If I connect via ssh:

glxinfo
Error: unable to open display

echo $DISPLAY prints nothing.

If I connect via ssh -Y:

glxinfo
name of display: localhost:10.0
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  149 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  19
  Current serial number in output stream:  20

echo $DISPLAY
localhost:10.0

In both cases:

ps aux | grep X

What does this error X Error of failed request: BadValue (integer parameter out of range for operation) mean?

Solution

Please specify the "name" of the available display to connect, :9 in the case above, and have it defined before running the glxinfo command, something like: DISPLAY=:9 /usr/bin/glxinfo -v -B

What are you connecting to using ssh? Is it Ubuntu? Which release?

[mrgloom]

Yes, it's Ubuntu 18.04, headless server.

[Pilot6]

Why would you run glxinfo on a headless server?

[mrgloom]

@Pilot6 Because I need to run some app that use OpenGL, so I need to check if my env is ok, is running glxinfo is a good way to check OpenGL setup is ok?

[Pilot6]

It lookslike the server doesn;t have a graphics adapter. So you can't run this kind of applications there.

[Oleg Afanasyev]

I'm having the same issue on Raspberry Pi4 aarch64, however the graphic adapter is there.

@mrgloom Did you end up figuring out how to do this?
