I've just installed papers on Trixie. I get this in xterm on GNOME on GDM on X11: $ papers my_great_document.pdf libEGL warning: MESA-LOADER: failed to retrieve device information MESA-LOADER: failed to retrieve device information MESA-LOADER: failed to retrieve device information libEGL warning: egl: failed to create dri2 screen MESA-LOADER: failed to retrieve device information MESA-LOADER: failed to retrieve device information libEGL warning: egl: failed to create dri2 screen The document itself seems to show up fine, though I have not checked all the details. From a user's viewpoint, these warnings/errors are garbage taking up precious terminal lines.
