Issues mixing cards with Ubuntu 14.04 or 15.04?

First, I'm using 15.04 atm, but I see a few threads saying 14.04 is a better version to use for mining. So if that's the case I'll be reinstalling to that soon(tm).

I have an R9 380 in my windows tower, and two fresh R9 390's, an XFX and MSI. Since I no longer have time for video games, I'll be moving my 380 to the rig and using onboard on my windows tower.

I assume for the sake of best Mh/s, since I can set up 3 different bash scripts so they all run in 3 different instances there won't be any sort of mining setting glitches between them.

What about drivers? Are there going to be any issues with that, that'll gimp performance?

H97 Anniversary
8Gb Ram
Intel G2350
60Gb SSD w/ Ubuntu 15.04 atm
XFX R9 390 atm (waiting on risers)
MSI R9 390 soon(tm)
ASUS R9 380 Strix soon(tm)

Honestly, don't ask.. I've read 4 or 5 guides, installed pretty much everything they said to install. I haven't touched my OC settings on the XFX, so I'm getting ~25Mh/s atm.

    There are no problems with using 15.04 for mining. I've using it on 7+ different machines for about a year now (yes 1 year) and I haven't had any major issues.

    It is fine to mix and match cards from the same manufacturer (i.e. AMD cards with AMD cards, etc.).

    There is no need to run each card with its own ethminer instance. ethminer will use as many OpenCL devices as it finds. If you feel the need, you can specify the number of threads to use with the -t command line option. But, it's really not necessary if you want ethminer to use all of the installed cards.

    Thanks Yukon.

    I was actually about to ask about headless rigs, but found your video.

    I may have to bug y'all about openssh though, install is really giving me a pain with errors.

    basically the same issue as

    but none of those fixes worked.
