[Bug 1906948] Re: Enabling OpenGL for GUI doesn't work on old laptop

[johannes]

I installed Qemu 5.0.0 from Debian Buster backports and I still get this
error.


qemu_gl_create_compile_shader: compile vertex error
0:2(10): error: GLSL ES 3.00 is not supported. Supported versions are: 1.10, 
1.20, and 1.00 ES

Title:
  Enabling OpenGL for GUI doesn't work on old laptop

Status in QEMU:
  Incomplete

Bug description:
  QEMU start command is:

  qemu-system-x86_64 -enable-kvm -m 2G -cpu host -smp 2 -cdrom
  ./linuxmint-20-mate-64bit.iso -boot d -vga virtio -soundhw hda
  -display gtk,gl=on

  
  and QEMU crashes immediately on startup and gives these error messages:

  If I remove "gl=on" it will boot. Does this just mean that this hardware is 
too old to run QEMU with OpenGL enabled in GUI, or is this a bug? 

  Host OS is Debian 10, computer is a Lenovo laptop with Core i5-520M
  CPU and its integrated Intel HD graphics GPU.

  QEMU version is 3.1.0 from Debian repositories.
