On Windows I can install an updated driver after CUDA toolkit installation. Can I install an updated driver on a linux CUDA installation? In my case I have 10.1.243 with the 418.87 driver installed. The driver manager offers 435.21. If I update will I damage my working CUDA installation?
You can install a new driver, without damaging your working CUDA installation, however you have to install the new driver using the same method (package manager or runfile installer) as was used to install the 418.87 driver.
If you don’t understand what this means, you may want to read the CUDA linux install guide, and/or read various other questions about it on these forums, or simply don’t update your driver. Because if you mix methods you can break your CUDA install.
