Hi, I am trying to get chimera run remotely on a linux server while logging into it from a mac terminal. I get the following error libGL error: failed to load driver: swrast X Error of failed request: GLXBadContextTag Major opcode of failed request: 150 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 1386 Current serial number in output stream: 1386 glxinfo gives me the following name of display: localhost:13.0 libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so libGL: driver does not expose __driDriverGetExtensions_swrast(): /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so: undefined symbol: __driDriverGetExtensions_swrast libGL: Can't open configuration file /mnt/raidc2/mhassan/.drirc: No such file or directory. libGL: Can't open configuration file /mnt/raidc2/mhassan/.drirc: No such file or directory. libGL error: failed to load driver: swrast display: localhost:13 screen: 0 direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose) server glx vendor string: SGI server glx version string: 1.4 It seems to run fine from a linux computer but has problems with a mac. I am using X11 forwarding when I log in. I have X11 on my mac. Could someone please help me out? Regards, Mosavverul Hassan.
