Perhaps CONFIG_DEBUG_FS is not set for the kernel you are using? I can
mount and unmount it just fine, and it shows up in the output of
"mount".
Does it show up when trying to mount it gives you the error message that
it's already mounted? If it does, I'd wonder why it's already mounted.

Did you install intel_gpu_dump by downloading it or by installing the
package intel-gpu-tools? Did it write something to intel_gpu_dump.txt?

Unfortunately not :( And I don't have an Intel graphics card, so I can't
try it out.
Isn't it possible to run the X server in the debugger? That's what the
debugging package should be good for.
