I have a machine which has a functional gpu it's using and I bought another gpu card to install. What are the first steps after installing the second card? I noticed that it tried to use the new card as the monitor gpu but since the drivers aren't in, the monitor wasn't working.
Using an older Ubuntu Suse with a Radeon HD 5570. I know it won't mine much but I already do ASICs and wanted to get started at least.
Remove first gpu.
Install new gpu.
Install new gpu drivers; don't do a clean install if asked.
Once miner works on new gpu; install old gpu as well and it should work fine.
