i did the nivida-driver-update. how do i know if it is finish unisntalling or not
If you read article then you can found such lines in article:
If update procedure will finish successfully you will see the following message:
Driver installation successful. Reboot now.
Now you can reboot your rig. After reboot check driver version and miner functionality.
BTW re-read arcticle. It complemented the typical mistakes and solve problems that may arise during update procedure.
