Thank you for your reply!

Firstly about the naming hickup. I am from computer music background and any piece of code is referred to as a patch. I know its quite different in shell scripting or general programming world. my bad

I tried your second solution of using .sh and running it after I close all programs running on Nvidia. it works. Thanks

If I were to place your script (!) directly inside usr/bin/primusrun then where would you suggest I put it. here's how it looks, unedited

#!/bin/bash

# Readback-display synchronization method
# 0: no sync, 1: D lags behind one frame, 2: fully synced
# export PRIMUS_SYNC=${PRIMUS_SYNC:-0}

# Verbosity level
# 0: only errors, 1: warnings (default), 2: profiling
# export PRIMUS_VERBOSE=${PRIMUS_VERBOSE:-1}

# Upload/display method
# 0: autodetect, 1: textures, 2: PBO/glDrawPixels (needs Mesa-10.1+)
# export PRIMUS_UPLOAD=${PRIMUS_UPLOAD:-0}

# Approximate sleep ratio in the readback thread, percent
# export PRIMUS_SLEEP=${PRIMUS_SLEEP:-90}

# Secondary display
# export PRIMUS_DISPLAY=${PRIMUS_DISPLAY:-:8}

# "Accelerating" libGL
# $LIB will be interpreted by the dynamic linker
# export PRIMUS_libGLa=${PRIMUS_libGLa:-'/usr/$LIB/nvidia/libGL.so.1'}

# "Displaying" libGL
# export PRIMUS_libGLd=${PRIMUS_libGLd:-'/usr/$LIB/libGL.so.1'}

# Directory containing primus libGL
PRIMUS_libGL=/usr/\$LIB/primus

# On some distributions, e.g. on Ubuntu, libnvidia-tls.so is not available
# in default search paths. Add its path manually after the primus library
# PRIMUS_libGL=${PRIMUS_libGL}:/usr/lib/nvidia-current:/usr/lib32/nvidia-current

# Mesa drivers need a few symbols to be visible
# export PRIMUS_LOAD_GLOBAL=${PRIMUS_LOAD_GLOBAL:-'libglapi.so.0'}

# Need functions from primus libGL to take precedence
export LD_LIBRARY_PATH=${PRIMUS_libGL}${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}

# And go!
export __GLVND_DISALLOW_PATCHING=1
exec "$@"
