Scaling for Powerful Fist

Given the description for powerful fist:

“You know how to wield your fists as deadly weapons. The damage die for your fist increases to 1d6 instead of 1d4. Most people take a –2 circumstance penalty when making a lethal attack with nonlethal unarmed attacks, because they find it hard to use their fists with deadly force. You don’t take this penalty when making a lethal attack with your fist or any other”

If a barbarian or other class with a damage die higher than 1d4 multiclassed into monk and received this feat, would it increase by a single step, such as 1d6 -> 1d8, or does this not increase at all?

My group has been discussing this for several hours now, send help.

rotate screen without breaking scaling gnome

whenever I use xrandr to rotate one of my screens/monitors, the natural scaling I set in gnome settings gets overridden to 100%. xrandr –current doesn’t change but for some reason this occurs. Is there a method to mitigate this issue or rotate screen from terminal that is more compatible with gnome (like the gui screen orientation picker in settings).

Ubuntu 16.04 Scaling of TWS Interactive Brokers on Dell XPS 15

I am having problem scaling the TWS application on my Dell XPS 15 when the resolution is set to 1920×1080. In my understanding, the tws script that can be downloaded from IB’s website calls local installation of Java, followed by configuration listed below and finally calls the appropriate *.jar files. This is what the configuration file looks like:

-Dinstaller.uuid=0d970b11-a492-452d-a91c-705ce8acf550 -DvmOptionsPath=/home/user/Jts/tws.vmoptions -Dsun.awt.nopixfmt=true -Dsun.java2d.noddraw=true -Dswing.boldMetal=false -Dsun.locale.formatasdefault=true -Djnlp.twslaunch.jars=jts4launch-976.jar;total-2018.jar -Djnlp.twslaunch.start=twslaunch-976.jar -Djnlp.twslaunch.codebase= 

I have tried setting these parameters as was suggested in other AskUbuntu/SO questions:

-Dsun.java2d.uiScale=10.0 -Dsun.java2d.dpiaware=false 

but without any success. Do you have any ideas what might improve the scaling?

Ubuntu 18.04 different scaling for bulit-in and external monitor

I have a 3840×2160 built-in monitor and one external monitor on the left side with 1280×1024 resolution. The built-in monitor is perfect for me with 200% scale. However, the external monitor has the same 200% scale which everything is magnified. Is there a way to have a different scale for these monitors? (100% for the external and 200% for the built-in one.)


hiDPI scaling fix for DaVinci Resolve 16

I am running ubuntu derivative Pop!_OS 19.04 in Gnome

I built a .deb package for DaVinci Resolve 16 with MakeResolveDeb and it seems to work fine, but it does not scale properly.

Scaling looks similar to this

This is a known (unfixed) issue, as seen here

The solution runscaled doesn’t seem to work.

Is there a known way to solve the scaling issue for this specific application?

Disable CPU frequency scaling?

I need to run ATLAS on my ubuntu laptop, but the software won’t run unless you dissable CPU frequency scaling. I’ve tried the instructions from here but they aren’t working on my Toshiba laptop. With freq-scaling on the software becomes useless.

Can anyone help?

Scaling GUIs differently on same resolution, but different sized monitors

I have two 1080p monitors, one is 32″ and one is 22″ my problem is that windows (and other GUIs) on the 22″ are much smaller than on the 32″.
I have an AMD graphics card, that supports something something called virtual super resolution, that lets me basically turn my 1080p 32″ into a 1440p monitor (albeit with low quality). That makes it so that the windows scale properly from monitor to monitors, but in Ubuntu (18.04) I don’t have that option. So, does anybody know if it is possible to achieve something similar, and if so…. how?

Thanks in advance, Asher

Largest eigenvalue scaling in a certain Kac-Murdoch-Szegö matrix

I’m looking at $ N\times N$ matrices $ M_N$ with elements $ $ M_N=\left( \rho^{|i-j|} \right)_{i,j=1}^N,$ $ where $ \rho$ is a complex number of unit modulus. These matrices with $ \rho\in\mathbb R$ and $ |\rho|<1$ have been studied in detail before, with a nice exposition to be found here, which includes some more references.

In the cited article, there is an implicit form of the eigenvalues, given through $ $ \lambda_j = \frac{1-\rho^2}{1-2\rho\cos\theta_j+\rho^2}, $ $ where $ \theta_j$ are roots of the following function $ $ G(\theta) = \sin[(n+1)\theta]-2\rho\sin[n\theta]+\rho^2\sin[(n-1)\theta]. $ $ (Even though only real $ \rho$ were considered in the article, this works for complex $ \rho$ also.)

Intriguingly, if $ \rho=e^{i\phi}$ , the largest eigenvalue of $ M_N$ seems to be essentially independent of $ \phi$ (as long as $ \phi$ is sufficiently different from 0 (i.e., $ \mathcal O(1/N)$ ). Since the inverse of $ M_N$ is almost tridiagonal (see the article for its form), it can be efficiently diagonalized numerically. I’ve checked up to $ N=10^6$ and the largest eigenvalue (mostly real) seems to almost follow a power law (roughly $ N^{0.85}$ ), but not quite. In fact, it looks slightly curved, so perhaps it is approaching $ N$ .

Another important thing I’ve noticed is that the $ \theta$ corresponding to the largest eigenvalue is very close to $ \phi$ , and seems to approach $ \phi$ as $ N\to\infty$ . Indeed, it is the same scaling as the actual eigenvalue $ \lambda$ , which follows from the fact that $ \theta=\phi$ makes the denominator of the formula for $ \lambda$ vanish. Expanding $ \theta=\phi+\delta\phi$ it becomes clear that $ $ \ln\lambda\to -\ln(\theta-\phi) + \text{const.} $ $

So I’ve been trying for a long time to extract how $ \theta$ approaches $ \phi$ from $ G(\theta)$ , but failed. I’d appreciate any pointers to a solution.
