I contacted Wolfram, and they told me another workaround that doesn't require using the -mesa option (which removes antialiasing and is slow since it renders on the CPU). You can use HardwareDepthPeeling like in: Style[ Plot3D[Sin[x + y^2], {x, -3, 3}, {y, -2, 2},PlotStyle -> Opacity[0.3]], RenderingOptions -> {"3DRenderingMethod" -> &...

There is a Mathematica build for Raspberry Pi OS. In essence that is a version of Mathematica for Debian OS on ARM platform. I can verify that the following works: Install Debian on Android using UserLAnd, which by default thinks it runs on arm64 architecture (I'm using an arm64 android device). Add armhf architecture by running "dpkg --add-...

Well in light of Mathematica 11 fonts in Linux are messed up, I disabled system fonts by renaming /etc/fonts/conf.d file and voila, Mathematica 7 start up without any trouble and Mathematica 8 also showed correct fonts as in Ubuntu. I deleted file by matching pattern method in groups and discovered the culprit as "45-generic.conf" that contained &...

Thanks to @ihojnicki, this is in fact possible. Since the frontend looks in ~/.Mathematica/FrontEnd/frontend.css for custom Qt CSS, we can write our own to change the colours of the various elements. Creating that file and adding the contents QScrollBar:vertical { background: green; width: 20px; } QScrollBar::handle:vertical { background: red; min-...

I tested the following method in arch linux. It works with Mathematica 12.2 + Arch Linux 5.10.13-arch1-2. To get around the problem, try AUR helper. I use yay. First, find out the build directory of yay. yay -P -g The output includes "buildDir":"/home/myname/.cache/yay" Then download Mathematica_12.2.0_LINUX.sh from Wolfram portal. Put ...

To capture the standard output of an external command, use Get with the command preceded by !: << "!whoami|tr a-z A-Z" (* JPD *)

(Information worth sharing for Windows users despite the linux tag in original question.) As this comment mentioned, there is an additional problem on Windows platform, which I will try to describe here, as long as a solution to it. The LibraryUnload failure problem on Windows Suppose one has a "standalone" library myLib.dll, which has nothing to ...

This was caused by having a custom $TAR_OPTIONS set. unset $TAR_OPTIONS fixed the issue.

simu[{DD_?NumberQ}] := (1 - Interpreter["Number"][ StringSplit[ RunProcess[{"cmd", "/c", "wsl", "simpson", "/mnt/c/windows/system32/simpson/redor2d_ty.in", ToString[DD], ToString[0]}, "StandardOutput"]]]) ListLinePlot[(simu[{9000}]), PlotRange -> All]

Bug confirmed by Wolfram (on 09-MAR-2021). Suggested workaround: execute DiscretizeRegion[Disk[]] before running the regular code. I guess this is needed to do some initialization; and it does the trick ;-)

By hacking SystemFiles/Links/FFmpegTools/Kernel/Common.m I managed to get a meaningful error message. The problem is that Mathematica bundles shared libraries which are incompatible with system shared libraries. In this case, ffmpeg depends on kerberos, which depends on openssl, which Mathematica bundles. The solution is to force Mathematica to use the ...

I have the Windows version, probably it works the same as yours. In Windows version of MMA: open Edit/Preferences/Interface and uncheck: "Show Suggestion Bar after last output":

The Wolfram support got back to me with a solution: A "Manual Clean Start". I saved my mathematica key somewhere easily accessible. (You find it under Help -> About...) Close mathematica Delete / rename (to have a backup just in case something happens) the UserBaseDirectory and the BaseDirectory: ~/.Mathematica ~/.Wolfram ~/.cache/Wolfram /usr/...
