Ubuntu 16.04 three monitor problem with HDMI and VGA port

I have two display ports on my laptop, Lenovo G580: HDMI and VGA port. If I used one of both to extend my monitor, it works. Also, Both ports works if I turn off built-in display. However, if I turn on all three monitors, only two of three works.

Here the error message,

could not set the configuration for CRTC 65 GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gsd_2drr_2derror_2dquark.Code2: could not set the configuration for CRTC 65 

I checked my CPU, i7-3520M supports up to 3 displays.

What’s wrong and how to solve this problem?

Can a 14th level Theurgy Wizard with the Arcana Domain cast their 8th/9th level spells after picking up three levels in another Full Caster class?

The Theurgy Wizard from UA: Wizard Revisited gets to choose a Cleric Domain at 2nd level. At 14th level they get the Arcane High Priest feature, which grants them the 17th-level benefits associated with their chosen domain.

A cleric who chose Arcana as their domain would therefore gain the Arcane Mastery feature, which reads as follows:


At 17th level, you choose four spells from the wizard spell list, one from each of the following levels: 6th, 7th, 8th, and 9th. You add them to your list of domain spells. Like your other domain spells, they are always prepared and count as cleric spells for you.

I’ve seen people on the internet argue that this 14th level wizard would be able to cast the chosen 8th and 9th level spells. This is of course not true, as the wizard in question would not have the necessary spell slots, regardless of whether those spells are always prepared.

But this wizard could pick up three levels in another Full Caster class (bard, cleric, druid, or sorcerer) or six levels in a Half Caster class (paladin, ranger, or this new UA revised artificer). Per the Multiclassing Rules, this would give this character a 9th level spell slot.

Question: Can this hypothetical character cast their 8th and 9th level spells granted by the Arcane Mastery feature via the Arcane High Priest feature, despite not being able to know or prepare any other spells of that level?

Disclaimer: I know that UAs are playtest material and not tuned for multiclassing. I know that the situation I describe in this question is very unlikely to come up in a real-life D&D game. I’m interested in an answer per RAW.

Three js raycaster WITHOUT camera

I seem to find only examples to use the raycaster with the camera, but none that just have a raycaster from Point A to Point B.

I have a working raycaster, it retrieves my Helpers, Lines etc. but it seems it does not recognize my sphere.

My first thought was my points are off, so i decided to create a line from my pointA to my pointB with a direction like so:

var pointA = new Vector3( 50, 0, 0 ); var direction = new Vector3( 0, 1, 0 ); direction.normalize(); var distance = 100;  var pointB = new Vector3(); pointB.addVectors ( pointA, direction.multiplyScalar( distance ) );  var geometry = new Geometry(); geometry.vertices.push( pointA ); geometry.vertices.push( pointB ); var material = new LineBasicMaterial( { color : 0xff0000 } ); 

var line = new Line( geometry, material );

This will show a line from my point (50 0 0) to (50 100 0) right trough my sphere which is at point (50, 50, 0) so my pointA and direction values are correct.

Next i add a raycaster: To avoid conflicts with any side effects i recreated my points here:

var raycaster = new Raycaster(new Vector3( 50, 0, 0 ), new Vector3( 0, 1, 0 ).normalize());  var intersects = raycaster.intersectObject(target); console.log(intersects); 

Seems pretty straight forward to me, i also tried to use raycaster.intersectObjects(scene.children) but it gives Lines, helpers etc. but not my sphere.

What am i doing wrong? I am surely missing something here.

Three variables bifurcation diagram

I’m trying to reproduce a paper. The point is that I have three variables and I will like to do the bifurcation diagram.The paper is this one:”A chaotic model of migraine headache considering the dynamical transitions of this cyclic disease” by Atiyeh Bayani, Sajad Jafari,Boshra Hatef and Julien Clinton.If you want to check it all. I’ll show you the model in wich all the parameters are fixed except (e01) which is going to be my bifurcation parameter.Any idea? enter image description here

How can I make a PC who is made up of three owls in a trench coat?

I’m a new DM. One of my players is insisting her character is really three owls in a trench coat (appears to be an elvish druid). Can someone help me figure out some way for this to have happened? How does one turn three owls into an elf?

I want to support her – this is her first time playing, and I want her to have a good time. I was thinking I was going to make it so that another person had transformed her from three owls into an elf, and finding the truth about this will be a minor side quest. I just want to know who/what could have made the transformation happen, and how it would occur – are there any spells for this?
