There are times when you may need to disable the nouveau graphics drivers in BT5R2 such as when you want to install Nvidia graphics drivers.
This is easily done with the following commands:
nano /etc/modprobe.d/blacklist.conf
Now add the following 6 lines at the end
blacklist vga16fb
blacklist nouveau
blacklist nouveaufb
blacklist rivafb
blacklist nvidiafb
blacklist rivatv
Save
update-initramfs -u
Finally reboot and nouveau drivers will now be disabled.
