cannot use GUI in ubuntu 24.04

[ninagestalt]

It worked for me before but since my upgrade to Ubuntu 24.04 I cannot open the pybullet gui anymore (may not be related though, not sure). I am working locally on my laptop without docker or anything.

I just want to run this simple example:

import pybullet as p
import time
import os 

os.environ["DISPLAY"] = ":0"

p.connect(p.GUI)

time.sleep(6)
p.disconnect()

This is my output, but no GUI opens:

pybullet build time: Nov 28 2023 23:45:17

Failed to retrieve a framebuffer config

I already tried adding the display env var, upgrading pybullet, running other guis like glxgears or xeyes works.
Any ideas how to solve this?
