Special Forums Windows & DOS: Issues & Discussions Poor Windows 10 Performance of Parallels Desktop 15 on macOS Catalina Post 303043266 by Neo on Thursday 23rd of January 2020 01:24:53 AM

Update:

Trying Parallels again on the 12-core Mac Pro running Catalina.

It's running a bit better since I repartitioned the boot disk.

Later, I will try installing NI-VISA and UltraScope for the RIGOL DS1054Z and see if I can get it to connect to the oscope, by isolating Windows 10 completely from the Mac. Earlier, I did not fully isolate them and had some problem connecting, so maybe if I isolate Windows 10 as much as possible from the Mac (an option in Parallels config) I can get RIGOL UltraScope to work.

It's only an "experiment", as I don't have an real intention to use UltraScope; I just want to see if I can get it to work since so much test equipment software (like software for arbitrary waveform generators and power supplies) are not supported on macOS, I thought "maybe" Parallels could be an option to get this Mac talking to various pieces of test gear; especially since I plan to buy an arbitrary waveform generator (AWG) in the $100 USD price range from AliExpress vendors after the Lunar New Year holiday is over and the Chinese businesses are back to work.

NAME
xdg-desktop-icon - command line tool for (un)installing icons to the desktop SYNOPSIS
xdg-desktop-icon install [--novendor] FILE xdg-desktop-icon uninstall FILE xdg-desktop-icon {--help | --manual | --version} DESCRIPTION
The xdg-desktop-icon program can be used to install an application launcher or other file on the desktop of the current user. An application launcher is represented by a *.desktop file. Desktop files are defined by the freedesktop.org Desktop Entry Specification. The most important aspects of *.desktop files are summarized below. COMMANDS
install Installs FILE to the desktop of the current user. FILE can be a *.desktop file or any other type of file. uninstall Removes FILE from the desktop of the current user. OPTIONS
--novendor Normally, xdg-desktop-icon checks to ensure that a *.desktop file to be installed has a vendor prefix. This option can be used to disable that check. A vendor prefix consists of alpha characters ([a-zA-Z]) and is terminated with a dash ("-"). Companies and organizations are encouraged to use a word or phrase, preferably the organizations name, for which they hold a trademark as their vendor prefix. The purpose of the vendor prefix is to prevent name conflicts. --help Show command synopsis. --manual Show this manual page. --version Show the xdg-utils version information. DESKTOP FILES
An application launcher can be added to the desktop by installing a *.desktop file. A *.desktop file consists of a [Desktop Entry] header followed by several Key=Value lines. A *.desktop file can provide a name and description for an application in several different languages. This is done by adding a language code as used by LC_MESSAGES in square brackets behind the Key. This way one can specify different values for the same Key depending on the currently selected language. The following keys are often used: Value=1.0 This is a mandatory field to indicate that the *.desktop file follows the 1.0 version of the specification. Type=Application This is a mandatory field that indicates that the *.desktop file describes an application launcher. Name=Application Name The name of the application. For example Mozilla GenericName=Generic Name A generic description of the application. For example Web Browser Comment=Comment Optional field to specify a tooltip for the application. For example Visit websites on the Internet Icon=Icon File The icon to use for the application. This can either be an absolute path to an image file or an icon-name. If an icon-name is provided an image lookup by name is done in the user's current icon theme. The xdg-icon-resource command can be used to install image files into icon themes. The advantage of using an icon-name instead of an absolute path is that with an icon-name the application icon can be provided in several different sizes as well as in several differently themed styles. Exec=Command Line The command line to start the application. If the application can open files the %f placeholder should be specified. When a file is dropped on the application launcher the %f is replaced with the file path of the dropped file. If multiple files can be specified on the command line the %F placeholder should be used instead of %f. If the application is able to open URLs in addition to local files then %u or %U can be used instead of %f or %F. For a complete overview of the *.desktop file format please visit http://www.freedesktop.org/wiki/Specifications/desktop-entry-spec ENVIRONMENT VARIABLES
xdg-desktop-icon honours the following environment variables: XDG_UTILS_DEBUG_LEVEL Setting this environment variable to a non-zero numerical value makes xdg-desktop-icon do more verbose reporting on stderr. Setting a higher value increases the verbosity. EXIT CODES
An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned: 1 Error in command line syntax. 2 One of the files passed on the command line did not exist. 3 A required tool could not be found. 4 The action failed. 5 No permission to read one of the files passed on the command line. SEE ALSO
xdg-icon-resource(1) EXAMPLES
The company ShinyThings Inc. has developed an application named "WebMirror" and would like to add a launcher for for on the desktop. The company will use "shinythings" as its vendor id. In order to add the application to the desktop there needs to be a .desktop file for the application: shinythings-webmirror.desktop: [Desktop Entry] Encoding=UTF-8 Type=Application Exec=webmirror Icon=shinythings-webmirror Name=WebMirror Name[nl]=WebSpiegel Now the xdg-desktop-icon tool can be used to add the webmirror.desktop file to the desktop: xdg-desktop-icon install ./shinythings-webmirror.desktop To add a README file to the desktop as well, the following command can be used: xdg-desktop-icon install ./shinythings-README AUTHORS
