Xorg crashes
« on: October 09, 2018, 04:05:39 AM »
Xorg periodically crashes, running Easy on my midi-tower PC. Intel hardware, using the Xorg 'modesetting' driver. The error log includes this:

"glamor0: GL error: GL_OUT_OF_MEMORY in glTexSubImage"

Googled, found others have same experience, mostly in 2018. It seems to be due to loading of /usr/lib/xorg/modules/

Here is another report;

This problem started a few months ago, after I had recompiled in OpenEmbedded, with updated Xorg packages. ...the downside of upgrading!

I have removed that module, X still works, but GL is now software rendering.

I had noticed that modesetting stopped working for me a few versions ago, probably right about the recompile time (0.9.2 maybe?). Any time it defaults to modesetting I was only getting a blinking cursor in the top left corner. Reboot to commandline and run xorgwizard to set to intel fixes it. Never got a desktop in modesetting though.

Problem is that any function can add this message and it usually origonates from another program.

"glamor0: GL error: GL_OUT_OF_MEMORY in glTexSubImage" is just the pass on message source.

For instance, Mesa, Evolution, OpenGl and the xorg-server itself are all known to have caused it, a lot of responsable thoughts seem to feed back to mesa though although the xorg-server (especially 1.18) is also blamed.

Have a look at the answer in, it will give you an idea of the complexity to find the source.

And from OpenGL itself is this,, which clearly states the problem.
