I have recently updated and rebuilt my MM installation.
I can browse to my MM via a remote web browser and things display fine, however on the HDMI output of the PI itself I just have a black screen.

In the logs I see,

[1502:0115/164948.881957:ERROR:viz_main_impl.cc(186)] Exiting GPU process due to errors during initialization
[1538:0115/164949.052412:ERROR:gpu_memory_buffer_support_x11.cc(44)] dri3 extension not supported.
[1507:0115/164949.107262:ERROR:command_buffer_proxy_impl.cc(128)] ContextResult::kTransientFailure: Failed to send GpuControl.CreateCommandBuffer.

I wonder if anyone might be able to point me in the right direction.

@AndyHazz Thanks for this awesome module. I’m also using it to pull bus information and it’s working well. I wondered if there was a way of stripping formatting off the content it scrapes? The table I’m pulling from (https://bustimes.org/stops/250012526) includes hyperlinks in several of the columns, and I’d like to format them as plain text.

Any ideas how that could be achieved?
Thanks again for this, it’s totally made things amazing :-)

v10.24.0

I used manual upgrade running: git pull && npm run install-mm

Having applied the latest update I am having an issue starting.
Output as below.

Any pointers as to what might be going wrong?

[1357:1004/172312.042226:ERROR:viz_main_impl.cc(186)] Exiting GPU process due to errors during initialization

I’ve written my own module to display a set of family tasks which rotate each week.
Once I’ve done some javascript to build a string of HTML, I display with.

        var element = document.createElement("div")
        element.className = "myContent
        element.innerHTML = output;
        return element

I just want to format this element with an existing magic mirror class so that the text doesn’t look massive and out of place, say “title” for example. But I can’t work out how to actually achieve that.

@MikeBishop I’m running MMM-Calendar3 and the default modules only.

No error now, but still a black screen

The following thread seems similar, but does not offer a solution
https://forum.magicmirror.builders/topic/17211/having-trouble-with-launch-perhaps-display-value?page=1

@sdetweil I am running the full desktop. yes.
This used to work but following a Magic Mirror and pi system update it no longer does.
I can see the desktop on boot up, but when pm2 runs the mirror then I get the blank screen.
