This is guide, howto install NVIDIA proprietary Linux drivers (manually using .run files) and disable Nouveau driver on Debian Buster 10 / Bullseye 11 / Sid and same method works with Ubuntu / Linux Mint / LMDE too. Linux Kernels 5.x are tested. Currently working NVIDIA drivers are: - 535.xx (535.146.02) - 530.xx (530.41.03) NFB - 525.xx (525.125.06) - 520.xx (520.56.06) - 515.xx (515.105.01) - 510.xx (510.108.03) - 470.xx (470.199.02) - 435.xx (435.21) Patched - 418.xx (418.113) Patched - 390.xx (390.157) - 340.xx (340.138) Patched This guide works with NVIDIA GeForce 6/7/8/9/200/300/400/500/600/700/800/900/10/20/30 series cards. This method allow you easily install / test / use different versions of NVIDIA drivers, you can test BETA drivers and switch back to stable. GNOME 40.3 on Debian / Ubuntu with latest NVIDIA 535.xx / 530.xx / 525.xx / 520.xx / 515.xx / 510.xx / 470.xx drivers works very smoothly and quickly, looks very nice. I have tested this guide with NVIDIA 340.xx (patched), 390.xx, 418.xx (patched), 435.xx (patched), 470.xx, 510.xx, 515.xx, 520.xx, 525.xx, 530.xx, 535.xx drivers/cards on latest Fedora.
