My latest Thursday, 20160908

It’s a rainy, hurricane #Tokyo today. Yesterday was earthquake Tokyo.
@edgarr0jas and I recorded @pvcsec #EP78. I edited and uploaded #EP77 but the show notes are slow going. Someone deleted last week’s run sheet. No @timothydeblock or @cmaddalena or @infosecsherpa, sadly.
I’ve been diving into #blockchain and #fintech during breaks working on a client deliverable.
I can’t help but chime in on the @apple announcement: I’m glad I bought my iPhone 6s+ a few weeks ago. I think there might be a run on them (https://apple.news/AtodeT67IQiKYmKB2s3fvvA).
Big security day today, product and provider oriented. @Dell finished their @EMCcorp acquisition ( http://www.wsj.com/articles/dell-closes-60-billion-merger-with-emc-1473252540), @HPE sold their enterprise software to @MicroFocus (whomever they are; http://reut.rs/2ckMx4c), and @Intel spun off @McAfee Security (http://www.wsj.com/articles/intel-nears-deal-to-sell-mcafee-security-unit-to-tpg-1473277803).
Oh, and I’m playing around with http://www.dayoneapp.com.

Ubuntu 12.04.1 Unity 3D with NVIDIA Optimus on T430s

Adding on to my display issues in my earlier post, I’ve reinstalled Ubuntu 12.04.1 and 12.10 many times – somewhere between one and three dozen times.

First, I followed all of Jim’s steps from the T530.

Second, I allowed that ppa:ubuntu-x-swat/x-updates repository to update my other drivers including the xserver-xorg-intel driver. Note that ia32-libs was not installed when I installed this. On one of my previous iterations I installed ia32-libs before I did the driver stuff. Ubuntu-x-swat installed a number of additional i386 packages which may have messed up things.

Third, I followed the Bumblebee instructions.

I will need to remember to ppa-purge both repositories before upgrading to 12.04.2. I hope most of this will roll into that release.

Other Notes and Random Thoughts

From time to time lightdm, the login display manager, won’t start. I do a …

sudo service lightdm restart

… from the command line to have it restart. That works fine.

Moving icons on the side dock thing only works properly on the main display. In my case it’s the laptop’s display.

Three displays – two DisplayPort and the built-in – does not work yet.

I’ve tweaked my power settings. Here’s what my /etc/default/grub looks like:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet nox2apic splash i915.i915_enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1 drm.vblankoffdelay=1″

Most of the grub settings I took from Ubuntu Wiki’s Power Saving Tweaks.
