I noted commits about this before, but here’s the instructions: how to use DragonFly on a Macbook Pro with dual GPUs.
There’s an update for Radeon DRM that matches it up (mostly) to what’s in Linux kernel 4.7.10. If it gives you problems, there’s some workarounds. Remember, this is in DragonFly-current, so anyone running 4.8 is unaffected.
Accidental topic this week: text interfaces!

BSDNow 192 is up, and has the normal news summary, plus an interview of Patrick M. Hausen.
The next NYCBUG meeting is May 3rd, in about 48 hours. Rob Seward will be presenting on random number generators. The same announcement for this meeting also notes the upcoming pkgsrcCon, BSDCan, and EuroBSDCon.

Francois Tigeot has brought in the ‘apple_gmux’ driver. If you have a Macbook with both Intel and NVIDIA video hardware installed, this driver lets you switch to the Intel hardware, and I assume take advantage of DragonFly’s accelerated i915 driver.
This week’s BSDNow covers a number of FreeBSD developments, Illumos network work, and an interesting in-depth discussion of the reasoning behind the transition from PC-BSD to TrueOS.
If you are using bhyve, and you want DragonFly on there as a ‘guest’ (not sure if that’s the right term), there’s a template available. (via)
For those of you who build custom kernels, the if_sl, if_ppp, and if_faith devices are now built as modules, not in the kernel. This means you can remove references to them in your custom kernel config – if you have one.
As part of a larger conversation about security measures, NX bit capability was added to DragonFly. You can turn it on or off, and it’s off by default so it doesn’t cause any surprises. As the first link in this post points out, your installed third-party software is more of a security issue than processor features, in any case.
Eclectic! I cover everything this week: computer history, modern pessimistic computing, odd hardware, strange software stories, comics, and tea.

This week’s BSDNow talks about a lot of OpenBSD news, gets into UNIX history, and interviews Kris Moore about FreeNAS/TrueNAS/TrueOS/etc.
In my ongoing quest to actually catch up to all the DragonFly commits recently, here’s a recent update to machdep.cpu_idle_hlt. Set this to affect power usage. I’m linking to this list of the different settings because, like RAID levels, nobody can or should remember every one.
If you are nearby, KnoxBUG is having a presentation from Caleb Cooper tomorrow night, titled “Advanced BASH Scripting“.
