Document PyQt benign errors to avoid confusion

Question

Closed this issue 2 years ago · 6 comments

When loading a PyQt window I get

libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

Initial googling suggests some interaction with the nvidia drivers of the host.

I haven't yet found a package I can install to provide swrast_dri.so

More investigation, and comparison to another app, needed.

For comaprison with dls_pmaccontrol, I get the error but the window is displayed.

So perhaps the error can be tolerated.

I've seen these errors too with dls-pmac-control but they seem to be benign for me. Are they stopping your app working?

I thought so, but given that dls-pmac-control works, probably it is something else.

Sure enough, I found the real cause of my problem. It is not related to these messages.

It would be nice to understand exactly what they mean, but I'm not going to do that now.
