Tarass's questions

I try to display the + sign of the number in the following character chains in G3 I want to see (-4)+(+4)= :

I'd like to have the same sort of script possibility (right click) with the budgie default file manager (nemo) as I use to have with Nautilus using the classical Ubuntu (both 20.04.1).

I try to authorize evince to open Geogebra and libreoffice files as links.

Using evince 3.18.2 on ubuntu 16.04.

Update 1: I've just installed a fresh 18.04 with the same problem.

Update 2: Here are the files to try. Both sort of links work fine with Okular.

For that I've added :

/usr/bin/geogebra ixr,
/usr/bin/libreoffice ixr,

just after :

# For text attachments
/usr/bin/gedit ixr,

in usr.bin.evince and ran : sudo /etc/init.d/apparmor restart

On a libreoffice link, evince says :

Impossible de lancer l'application externe.
L'exécution du processus fils « libreoffice » a échoué (Permission non accordée)

And no other message in the terminal from wich evince is launched.

On a geogebra link, evince says nothing :

but in the terminal windows from wich evince is launched there is the message:

/usr/bin/geogebra: ligne 9: /usr/bin/basename: Permission non accordée
/usr/bin/geogebra: /usr/share/geogebra/geogebra : /bin/bash : mauvais interpréteur: Permission non accordée
/usr/bin/geogebra: ligne 19: /usr/share/geogebra/geogebra: Succès

Geogebra is not launched but the icon in the launcher is blinking a while.

I want Okular opens pdf links in a new tab or better in a new window. I have enabled open new files in a new tab, but it doesn't work : Okular opens the new file instead of the previous file : one window, one tab with the link opened, the original document is vanished.

Here an example :

Essai.pdf has a link on bob.pdf (click on the picture) (Evince or Adobe Reader XI open the link in a new windows.)

Any idea to make it work ?

Ubuntu 16.04 Okular Version 0.24.2 Using KDE Development Platform 4.14.16

I try the following the prescriptions of this answer : How to change Gedit embeded terminal plugin colors?

I used them successfuly with ubuntu 14.04 and gedit 3.10.1, without clearing the palette.

With 16.04 and gedit 3.18.3, it doesn't work.

I try to clear the palette clear. There is allways an error message if the argument is totally black.

[] is accepted, but the colors are not changed.

Any help ?

I have the following error message in AR XI :

There was an error opening this document. This file cannot be found

when I try to open a pdf document by clicking-right on it, both with default application or special script.

If the document is in the last folder I used in AR, it works fine, but if I try to open a file in another directory, I have this error message.

The script I use :

#!/bin/bash
/usr/bin/wine "C:\\Program Files\Adobe\Reader 11.0\Reader\AcroRd32.exe" $1

the desktop file :

[Desktop Entry]
Name=Adobe Reader XI
Exec=env WINEPREFIX="/home/nico/.wine" wine C:\\\\Program\\ Files\\\\Adobe\\\\Reader\\ 11.0\\\\Reader\\\\AcroRd32.exe %f
Type=Application
StartupNotify=true

I've just installed Adobe Reader XI on ubuntu 14.04, but I can't have this program on right click. I used to some times ago, but I don't remember how to do that.

I tried some .desktop file in .local/Applications directory but I can't have AR in other application in contextual menu.

I made a ICC color profile for my scanner I can use it in Xsane. But if I want to scan a BW image, Xsane doesn't find a BW ICC profile.

If I use the color one as BW, Xsane claims for error because the color one is tagged RGB.

How to avoid this problem :

• Use the color ICC as BW, as fake?
• Or make a BW ICC profile? but how using Ubuntu?

I try to use Acrobat Reader on a second screen.

If I open AR on the second screen and ask for fullscreen mode, AR open the fullscreen on the main screen. It is impossible to video project in fullscreen mode on the second screen.

I use Ubuntu 14.04 and AR 9.4.2.

Any idea why ?
