Is this a requirement an X client can impose? An option in some port? A sysctl? ...? I see other programs giving the same message, but then proceed with software rendering. > The DRM/DRI > task is being performed directly on the hardware the program is > running on and maybe cannot be redirected to a remote X system. Being a headless server, I don't think I've enabled DRI on this box... I don't load any related kernel module and I don't even have an Xorg.conf. BTW, I forgot to mention this is 10.3/amd64. > The somehow direct access to the hardware maybe cannot be tunneled > over X11/SSH. Ok with this; I'd just like to avoid DRM/DRI at all. > The messages indicate that the DRM device cannot be > found and the r600 (Radeon?) driver cannot be loaded. There is no Radeon card on the headless box; the CPU is an i5 (with integrated GPU) and that's all. I've got a Radeon on the client (i.e. where the X server runs), but does this matter? > This is a quire early error of libGL. Sorry, I don't understand what you mean here. > On the other hand, if you use software rendering, it _should_ work. Exactly as I thought. So the question is: how do I force software rendering? bye & Thanks av.
