I posted a question on Ask Ubuntu - maybe I will get an answer?

Ubuntu 26.04

Some applications, when executing. just have a red dot appear next to the icon. Others create a gear...

For example, emacs 30.2 just has a red dot appear. The desktop file:

[Desktop Entry]
X-SnapInstanceName=emacs
Name=Emacs
GenericName=Text Editor
Comment=Edit text
MimeType=text/english;text/plain;text/x-makefile;text/x-c++hdr;text/x-c++src;text/x-chdr;text/x-csrc;text/x-java;text/x-moc;text/x-pascal;text/x-tcl;text/x-tex;application/x-shellscript;text/x-c;text/x-c++;
X-SnapAppName=emacs
Exec=/snap/bin/emacs %F
Icon=/snap/emacs/current/usr/share/icons/hicolor/scalable/apps/emacs.svg
Type=Application
Terminal=false
Categories=Development;TextEditor;
StartupNotify=true
StartupWMClass=Emacs

None of these seem to change Maple 2023 behavior.

Thanks.

I asked Tech Support about this on 12/13.2023. Their reply:

"We've asked the Maple R&D teams to investigate what is causing the until repetition condition to behave differently than the other repetitions on your worksheet. We'll let you know what they find.  "

Case #: 00150534.

Please submit a bug report.

                            "while"

Error, cannot determine if this expression is true or false: FAIL

@Carl Love 

Thanks.

I asked Tech Support to look into the difference in handling of while and until.

> plot(x^4-10*x^2+1) works on Windows 10 Maple 2022.2 with the same build number as my Linux version.

Can someone try this on Ubuntu 22.04 and Maple 2022.2?

ErrorInPlot1.mw

plot(x^3-10*x^2+1) should work and plot(x^4-10*x^2+1) should produce an error message.

@sand15 

Maplet is the popup window that displays the plot.

@acer 

I finally uploaded a worksheet: ErrorInPlot.mw Sorry I did not do this earlier.

I started maple by first removing the PATH environment variable. I think this should (mostly) eliminate maple picking up something outside maple from my system. Possilby excepting Java???

If I assign plot() to P, it produces an inline plot. I have plot set to use maplets..

 Standard Worksheet Interface, Maple 2022.2, Linux, October 23 2022 Build ID 1657361

This is context related: See the last four lines in the worksheet.

works correctly, producing a correct plot in a maplet

> restart
> plot(x^4-10*x^2+1)
produces the error message

====================================
from cmaple, this produces the same error message

Linux, Ubuntu 22.04.

If I start Maple with:

env -i DISPLAY=:0.0 /usr/local/Maple2022/bin/xmaple

it works.

Maybe Maple is using something from my system? I may have scrambled something using apt [install|purge|update]?

@jganding 

That was a typo - In Maple I used :=.

@acer 

I realize the OP used Maple 2023, but, I have Maple 2022.

Content fails when using indet A or m.

@Kitonum 

How do I eliminate the warning message from Maple 2022?

andmap(t->is(`and`(seq(eval(eq,t),eq=eqs))), soln);
Warning, (in anonymous procedure) `eq` is implicitly declared local
                              true

@Carl Love 

Made me think for a while...

It satisfies Maple's requirements that the Matrix elements be 1...m, m=number of coprimes and the labels are the coprimes to n in 1..n-1

Thanks.

@dharr 

Thanks for helping me understand this.
