    Hi!
    Maybe this is related to killing NoVNC, don’t do it. You can get a second ssh session to run any other command, try it out.

    NOVNC has nothing to do with it, I get error message after executing firefox command before even starting NOVNC

    Through discussions with a friend, using export DISPLAY=:1.0, firefox started but displayed a new error of below. But heck, after displaying error message, my AWS instance freezes and I could not even connect anymore, even after rebooting or stopping and then restarting through AWS console, any suggestions ?

    The glxtest error message when running Firefox typically indicates a issue with the OpenGL or graphics drivers. Here’s what it might mean:

    – glxtest is a test for OpenGL support, which Firefox uses for hardware acceleration and rendering.
    – If glxtest fails, it can indicate a problem with:
    – OpenGL drivers
    – Graphics card configuration
    – X server setup
    – Library dependencies

    Common errors include:

    – glxtest: unable to open display
    – glxtest: failed to create GLX context
    – glxtest: failed to create OpenGL context

    To address this, try:

    1. Updating graphics drivers
    2. Checking X server configuration
    3. Disabling hardware acceleration in Firefox (by setting gfx.direct2d.disabled to true in about:config)
    4. Verifying library dependencies (like libGL, libGLX, or libX11)

    By the way in video, I saw same error briefly displayed, but it went away, unlike on my AWS instance where server instance froze machine and I cannot even reconnect after rebooting/restarting

    Hi!
    Are you able to ssh into the instance?

    Let me know.

    Nope, that’s what I indicated earlier. Ever since firefox froze server, my ssh connection times out even after I rebooted/restarted machine and even though I did not make any change to inbound firewwall rules

    Hi!
    Then terminate that instance and create a new one, it might be broken.

    found the problem, looks like not only did AWS change the hosting region on me but they also changed the IP (and they give no notification), so back in business in terms of ssh connecting, but still a dead end cause even though export DISPLAY command working, FIrefox not, oh well, so much for the exercise (see attachment) unless u have some additional thoughts. Maybe I have to upgrade to paying AWS instance ?

    Hi!
    In any case try with a new instance, something might be broken in the current one.

    Greetings!
