Server aborts reproducibly when I try to start Mathematica 11.1. I didn't have this problem until now on a up-to-date openSUSE Tumbleweed.

The exact Mathematica version is 11.1.1.0. The error happens independent of desktop environment or logged-in user. The crash happens only with options "AccelMethod" "glamor" and "DRI" "2". With "AccelMethod" "EXA" or "DRI" "3", Mathematica does not crash the X server. Instead it outputs the message "failed to create drawable" the moment it would crash the server.
Can you get a gdb backtrace of the crash?

Please attach the corresponding Xorg log file. So far, this looks like an X server bug: cpp == 0 in radeon_alloc_pixmap_bo, which means pixmap->drawable.bitsPerPixel <= 7 after fbCreatePixmap in radeon_glamor_create_pixmap, but it should be 32. Can you maybe also provide the output of the following at the gdb prompt when it crashes? p *radeon_glamor_create_pixmap::pixmap

Not really. This turns it into a segmentation fault when I add the two lines to the source package[1] provided by openSUSE.

(In reply to Michel Dänzer from comment #9) > Created attachment 139609 [details] [review] [review] > Bail from dri2_create_buffer2 if we can't get a pixmap > > Please try this patch on top. This works. Mathematica no longer crashes the X server.
