After investigation, I realized that even if OpenGL context is created for pixmap rendering, printing from loch on my Linux machine actually does not work. So I have rearranged the code and disabled rendering to pixmap on Linux completely. It seems to work using just screen OpenGL buffer for tiled rendering (for big images). If anybody is interested in testing, your feedback is welcome. S. On Sat, 7 Dec 2019 at 00:15, Olly Betts <olly@survex.com> wrote:

If it is lxR2P.c what fails (it is off-screen rendering to pixmap - for large renderings) then it should be quite easy to disable it. Could you please somebody try to comment out following line (lxGLC.cxx:1938)?
this->m_OSC->m_r2p = R2PCreate(w, h);
then recompile loch and try whether it can start?
Yes. I've applied slightly more nuanced version of that (which tries to create the context, but on failure doesn't exit) and uploaded a new debian package to unstable. This obviously isn't a perfect fix, but it beats loch being unusable, and if it was working for anyone before it should still with off-screen rendering.
I've attached the patch I applied.
