I just noticed the relevance of the fact that the screenshot is of a GUI popup…you wouldn’t be able to see that popup or get a GUI screenshot if you couldn’t get into the GUI. Therefore, it seems that the problem is probably part of the startup of the GUI software and perhaps not “/etc/profile” (perhaps it is just a bad error message). Is it possible to show the dmesg output prior to starting the GUI, and the again after the GUI starts? Basically I’m trying to find what logged as a result of the GUI starting, and also to search for a similar error prior to the GUI starting. Knowing the timing of this showing up would make debugging much easier. It might be possible to find the line in “/etc/profile” is related to the GUI only.
