I uninstalled nvidia driver with nvidia-uninstall then I installed
driver from ELrepo.
kmod-nvidia-340xx-340.96-1.el6.elrepo.x86_64
nvidia-detect-367.44-1.el6.elrepo.x86_64
nvidia-x11-drv-340xx-340.96-1.el6.elrepo.x86_64
nvidia-x11-drv-340xx-32bit-340.96-1.el6.elrepo.x86_64
To get more output while starting Allegro :
setenv LIBGL_DEBUG verbose
libGL: screen 0 does not appear to be DRI2 capablee
libGL: OpenDriver: trying /usr/lib/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/dri/swrast_dri.so
libGL error: dlopen /usr/lib/dri/swrast_dri.so failed
(/usr/lib/libLLVM-3.6-mesa.so: symbol
_ZNSt15__exception_ptr13exception_ptrC1Ev, version CXXABI_1.3.3 not
defined in file libstdc++.so.6 with link time reference)
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
Termination codes: exit=3, signal=11, errno=11
adding /usr/lib/nvidia to LD_LIBRARY_PATH fixed the error
I hope this will be useful for Allegro PCB Designer.
