i tried to turn off my discrete graphics by writing a script : sudo chown username /sys/kernel/debug/vgaswitcheroo/switch sudo chown username /sys/kernel/debug/ echo OFF > sudo chown username /sys/kernel/debug/vgaswitcheroo/switch
the script worked fine but when i tried to run in on boot by adding it in update-rc.d file i cant boot into my system anymore. the system freezes on startup. i placed the script.sh file in init.d folder. i changed file permissions : chmod 777 /etc/init.d/off_discrete.sh & created a symlink to /etc/rc.d/ ln -s /etc/init.d/off_discrete.sh /etc/rc.d/ i can get into root terminal through elementary OS recovery mode but i cant remove the entry from system startup. can someone plz help. Plz tell me why this happened and how can i fix the issue in future. and how to reverse the process so that i can boot again.
