The cause of the problem is a conflict between the programs "*Global Keyboard Shortcuts*" and the window manager *OpenBox* for the keyboard shortcut "**Ctrl+Alt+D**". Methods proposed on the Internet to solve this problem are either destructive to the operating system (full [shutdown](https://forum.lxqt.org/t/solved-openbox-lxqt-keyboard-shortcuts/569/3) programs *Global keyboard shortcuts*) or difficult for most users ([editing](https://salsa.debian.org/lxqt-team/lxqt-globalkeys) openBox window manager rc.xml file). The method I propose does not have these disadvantages and is suitable for users of any level of training. **Solution:** 1. Click **"Start" - "Settings" - "LXQT Settings" - "LXQT System Settings"**. [ ![](https://ra1ahq.blog/images/3/e/f/6/4/3ef64b1a7aca362c35bce8790041a6b26e097594-menu.png)](https://ra1ahq.blog/images/3/e/f/6/4/3ef64b1a7aca362c35bce8790041a6b26e097594-menu.png) 2. Open the window item "LXQT Settings" -**"Keyboard shortcuts"**. [ ![](https://ra1ahq.blog/images/1/0/9/7/2/109726f9fbaf1143d086dbf58fd7557987a78692-keyb-shortcuts.png)](https://ra1ahq.blog/images/1/0/9/7/2/109726f9fbaf1143d086dbf58fd7557987a78692-keyb-shortcuts.png) 3. Assign to action "**Show desktop**" combination **"Shift + Control + D"**. To do this: \*Scroll down the list to "**Show desktop**" - Double-click on the line "Show desktop" or select this item and click on the " button**Edit**". *Click in the form field "**Keyboard shortcut**" (time countdown begins)* Press keys **Shift+Control+D**(the countdown will stop and a new keyboard shortcut will be added to the field) - Confirm changes:**"OK", "Close"**. [ ![](https://ra1ahq.blog/images/5/4/f/5/6/54f56e71bfc39f20f80e7d7cd98e557a22c4ed44-shift-control-d.png)](https://ra1ahq.blog/images/5/4/f/5/6/54f56e71bfc39f20f80e7d7cd98e557a22c4ed44-shift-control-d.png) This method of solving the problem is also convenient because it works when controlling the computer remotely. For example, using RDP or VNC. At the same time, the action **"Shift + Control + D"** "Minimize all windows and show desktop" is triggered on the remote computer, and when clicked **"Alt + Control + D"** the desktop of the local computer is shown. ### Related publications [ ![](https://ra1ahq.blog/images/f/3/a/2/c/f3a2c07ef5b32c0308ab703405a5a5ca87b75283-archer-ac600-728.webp) Installing the kernel driver for the TP-Link Wi-Fi adapter after updating the Debian OS ](https://ra1ahq.blog/en/ustanovka-draivera-yadra-dlya-wi-fi-adaptera-tp-link-posle-obnovleniya-os-debian) [ ![](https://ra1ahq.blog/images/d/2/5/c/7/d25c7282750b398f71041fb8b90640b692e7e4b8-decibelfmtitle.png) Linux Cinnamon Desktop Applets for Listening to Internet Radio Stations ](https://ra1ahq.blog/en/applety-dlya-rabochego-stola-linux-cinnamon-dlya-proslushivaniya-internet-radiostancii) [ ![No picture](https://ra1ahq.blog/user/themes/mytheme/images/no-image.png) Passing a parameter to a Linux module/driver ](https://ra1ahq.blog/en/peredacha-parametra-modulyu-draiveru-linux) [ ![](https://ra1ahq.blog/images/5/c/4/e/a/5c4ea9c8c3f0b4dd890116d8fe7cbadfdb9814ba-archer-ac600.webp) Installing the TP-Link Archer T600U Nano Wi-Fi adapter driver in Debian 13 "Trixie" ](https://ra1ahq.blog/en/ustanovka-draivera-wi-fi-adaptera-tp-link-archer-t600u-nano-v-debian-13-trixie) [ ![](https://ra1ahq.blog/images/b/f/f/0/f/bff0f99f5897e0420fac9a6eef7254247f39c29d-pulseaudio-equalizer.png) Installing the audio equalizer pulseaudio-equalizer-ladspa on Linux ](https://ra1ahq.blog/en/ustanovka-v-linux-ekvalaizera-zvuka-pulseaudio-equalizer-ladspa) [ Backward](https://ra1ahq.blog/en/staticheskii-ip-adres-v-ubuntu-i-linux-mint-nastroika "Previuous page") [ Forward ](https://ra1ahq.blog/en/kak-nauchitsya-cw "Next page") ## Languages -
