Comment 13 for bug 1683587

Thanks.

It looks like there's also an out-of-tree driver available, if people want to go that direction. (For example, it's available from Dell at https://downloads.dell.com/FOLDER04588242M/1/UnifiedDriver_7.700.52.00_SLES12.tar.gz , found on the drivers and downloads page for the R640 or R740 after selecting SLES or RHEL.) I haven't tried building it on Ubuntu yet.
