====================

* Device #1: GeForce RTX 2060 SUPER, 7653/7979 MB, 34MCU

* Device #2: GeForce RTX 2060 SUPER, 7881/7982 MB, 34MCU



1) Does it matter if I am using Desktop Ubuntu, or do I need to use server?

Same.

2) How do I edit this patch to apply to secondary video cards? (I would eventually like to have 6-8 identical cards)

Do not edit. Cards are already detected.



Please post output of :

hashcat -I

and hashcat -b -m 0




Output of hashcat -I

the output of hashcat -b -m 0 is:

hashcat (v6.1.1-120-g15bf8b730) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

* Device #2: WARNING! Kernel exec timeout is not disabled.
            This may cause "CL_OUT_OF_RESOURCES" or related errors.
            To disable the timeout, see: https://hashcat.net/q/timeoutpatch
* Device #4: WARNING! Kernel exec timeout is not disabled.
            This may cause "CL_OUT_OF_RESOURCES" or related errors.
