I installed Mesa, which will replace the original libGL.so . This GL driver can make 3D graphic rendered with remote ssh. I didn’t use libGL from NVIDIA, because I need it works on a computing cluster without GPU.
I didn’t get “which X11 call”. I run gdb as debugger with “X11.Sync:on” in .rootrc, and checked it by “gEnv->Print()” . When the breakpoint hit, debugger prints out "Thread 1 “root.exe” hit Breakpoint 1, RootX11ErrorHandler (disp=0x2db1a00, err=0x7fffffff9960) at /opt/root_src/graf2d/x11/src/GX11Gui.cxx:174
174 XGetErrorText(disp, err->error_code, msg, 80);
