I'm running Raspbian “wheezy”, a Debian based Linux distribution for the Raspberry Pi and I would like to know where I can change the desktop environment that boots with the OS. In particular, how can I replace LXDE with a custom QT or Java program?

I have to PC and netbook runs on fedora * PC - Fedora 21 (Workstation) * Netbook - Fedora LXDE Both of these computers are connected to the same network (PC wired and netbook wireless) My HP Deskjet 1010 printer is connected to the PC via a USB cable. I want to enable printing over network for my netbook.

I have installed Lubuntu desktop on a Ubuntu 20.03 LTS server. The desktop works fine when I log on to it locally. I can see the SDDM and I can chose between various sessions for the desktop (Lubuntu, LXDE, LXQt). However, I set up a vnc server and I configured (as per the instructions I found online) the ~/.vnc/xstartup fileto looks like this:

#!/bin/sh
xsetroot -solid grey
export XKL_XMODMAP_DISABLE=1
openbox &
/usr/bin/lxsession -s Lubuntu &

When I connect though, all I can see is a grey screen. Any ideas? Thanks a lot!

I Installed Ubuntu 18.04 and removed gdm3 package. Now on startup I get LXDE GUI with my default admin user logged in (the one created after initial OS setup with sudo capabilities). I wish to create a guest user which not belongs to sudo group and make the system login automatically with that user to restrict guest actions. In case of need we can logout and login as the admin. I don't know if its done in systemd or LXDE settings and how to achieve that.

I want to develop a simple GUI panel using Raspberry Pi 4 and Touchscreen LCD module. My desktop is LXDE and below is the uname output. Linux rpi4 6.6.51+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.51-1+rpt3 (2024-10-08) aarch64 GNU/Linux I will have only website shortcuts and possibly VLC on the desktop. What I can't figure out is how to emulate similar behavior as Android. I want to be able to open shortcuts with single tap on the icon as well as scroll the page in the browser using tap and swipe. Right now I need to double tap on the screen to open shortcuts. Trying to scroll in the browser window just selects the text in both Chromium and Firefox. Below is evtest output. How needs to be adjusted in the config files to achieve what I want?

I am using Debian 9. After installing Gnome I only see my mouse cursor on my computer screen. I uninstalled Gnome and enabled X11 but it didn't work. I need to connect to the board I use via ssh and type > startx in order to get an image on the screen. I may have messed something up while installing gnome. **Update:** apt install gdm is not working: root@linaro-alip:~# apt install gdm Reading package lists... Done Building dependency tree Reading state information... Done Package gdm is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: libgdm1 cinnamon-control-center-data E: Package 'gdm' has no installation candidate **Update 2:** dpkg-reconfigure lightdm >> I manually selected lightdm root@linaro-alip:~# systemctl enable lightdm

Synchronizing state of lightdm.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable lightdm
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias
settings in the [Install] section, and DefaultInstance for template units).
This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).
4) In case of template units, the unit is meant to be enabled with some
   instance name specified.

The problem is still not fixed. When I use the below command it says the file does not exist. How can I fix this? update-rc.d '/etc/init.d/xserver start' defaults

update-rc.d: error: initscript does not exist: /etc/init.d//etc/init.d/xserver start

On my new built Debian 12 machine running LXDE, I found by accident that a 4 finger tap on my touchpad will cause an immediate screen off (same as if I'd done xset dpms force off). I _think_ a 3 finger tap does a paste, but I'm not sure. How can I find what all these obscure gestures do, and how I can configure LXDE (openbox) to do more "interesting" things?

I am configuring a arch based machine with a minimal desktop setup. I am logging into a qtile session, and I have the 'lxsession' package installed and run on start, but I am not logged into an lxde session. My problem is that I have some desktop files that keep appearing in ~/.config/autostart and I do not understand why. There is no autostart folder in ~/.config/lxsessions, there is no /etc/xdg/LXDE folder and nothing related to autostart in /usr/share/lxsessions. I keep deleting the .config/autostart folder contents, everything is disabled on the lxsession gui setting app for autostart, but on each reboot the desktop files are back. Does anyone have an idea of why that could be ?

I have the following keyboard (HHKB JP).  I'm using Lubuntu 14.04, and I've edited /usr/share/X11/xkb/symbols/us to implement a [custom layout](http://mkweb.bcgsc.ca/carpalx/?full_optimization) . Now, I want to use the following keys as 5th, 6th, 7th, ..., and 20th level modifiers. (On Windows, I accomplish this with AutoHotkey, and now I can't live without (at least some of) them.) I have 2 problems. 1. I don't know what the "names" for some of the non-standard keys on the keyboard (in order to add them to /usr/share/X11/xkb/symbols/us). 2. I don't know how to add extra modifiers with xkb (I understand xmodmap is deprecated), specially "normal" keys like 9. My questions are: 1. How do I figure out the names/codes for the mystery keys (eg. key )? 2. How do I add an arbitrary number of modifier layers to any given key? Note: perhaps this cannot be accomplished with XKB. I'd be delighted to know of some scripting tool that can implement this.

I downloaded an application "sendanywhere_latest_amd64.deb" and installed it with dpkg: sudo dpkg -i sendanywhere_latest_amd64.deb Selecting previously unselected package sendanywhere. (Reading database ... 450701 files and directories currently installed.) Preparing to unpack sendanywhere_latest_amd64.deb ... Unpacking sendanywhere (22.6.13-1237) ...

Processing triggers for menu (2.1.48) ... There are so many menu in my desktop: It take me time to search one by one in "Accessories Debian Education Graphics Internet Office Other Programming Sound&Video 'System Tools' ",how can know quickly which menu does the app be installed in ?

I'm setting up a Debian system, with LXDE as the Desktop Environment (really, I'm just remastering a *Raspberry Pi OS* image). I have an application that ships with a [.desktop](https://specifications.freedesktop.org/desktop-entry-spec/latest/) file. Cool! Unfortunately that MyApplication.desktop file contains the following line that prevents the icon from being shown in the menu:

NoDisplay=true

Now, I would like to find a generic way to override just this single field in the MyApplication.desktop file for the entire system, without touching any other fields - think of it as an overlay. Especially, I try to *avoid* a solution like this...

sed -e 's/^NoDisplay=true/NoDisplay=false/' /usr/share/applications/MyApplication.desktop \
    > /usr/local/share/applications/MyApplication.desktop

... as this would lose any changes of the MyApplication.desktop introduced by newer upstream versions of that file (and presumable leave the menu-entry intact, even if after I've uninstalled MyApplication from the system) Obviously, the standard does not allow only partial .desktop files, e.g. this would not work:

$ cat /usr/share/applications/MyApplication.desktop
[Desktop Entry]
Name=My Cool Application
GenericName=My Application
Exec=myapp %f
Icon=myapp
Type=Application
Terminal=false
Categories=Application
NoDisplay=true

$ cat /usr/local/share/applications/MyApplication.desktop
[Desktop Entry]
NoDisplay=false

Similarily, there's no include mechanism:

$ cat /usr/local/share/applications/MyApplication.desktop
include=/usr/share/applications/MyApplication.desktop
[Desktop Entry]
NoDisplay=false

what are my options to achieve that?

Is it possible to trigger the appearance of the lxpanel for Control for the dhcpcd network interface or any other panels of the lxde-profile? Thanks in advance! Edit: Thanks for your comment @KGIII about the need to explain further. I'm working with the Raspbian GNU/Linux 10 (buster) OS. By default there is - for example - the possibility to use the LXDE-panel for network settings. I want to know, if i can call this UI-Panel by command somehow, to open it in a in a own written software by pressing a button. Update: Sometimes it helps a lot to read the manual. There I found the command lxpanelctl. In ~/.config/lxpanel/Profilename you are able to find out the config for the bar and panels on it. Sadly the call of lxpanelctl dhcpcdui is not bringing the expected result, but it seems It's bringing me near it. I also found someone having the same question two years ago :) https://raspberrypi.stackexchange.com/questions/68149/open-the-network-list-with-command-line/68150

I am working on a project using BeagleBone Black and an LCD cape. For that, I downloaded the current BBB IOT image from their website and installed LXDE for user interface. I want to create an application that starts at boot on the LCD. I need to remove the login step at the startup. I think that LightDM is used as a desktop manager (maybe helps), but for now I only succeeded to auto insert the username. My question is how I can pass this step without any other user intervention.

I'm using a LXDE desktop. I created a shortcut in the desktop to a python program, which can be passed files to, which are then opened in the GUI. I mean passing files (file absolute paths) to the command by drag'n'dropping them over the shortcut on the desktop. In fact this is already working, but only if I set Terminal=true in the Desktop Entry, which obviously makes the terminal be opened. I wanted to know if there's a way to pass the arguments to the command without the need to open the terminal. I'm creating the shortcut like this: [Desktop Entry] Name=TBOPlayer Comment=UI for omxplayer Exec=python /path/to/tboplayer/tboplayer.py "%F" Icon=/usr/share/pixmaps/python.xpm Terminal=true Type=Application Is there a way to do this?

I want these 2 commands to run on boot. xinput --set-prop "Razer Razer DeathAdder" "Device Accel Constant Deceleration" 4 xinput --set-prop "Razer Razer DeathAdder" "Device Accel Velocity Scaling" 1 I tried putting these 2 commands /etc/rc.local, .zshrc, also in /etc/xdg/lxsession/Lubuntu/autostart, but nothing seems to happen. Any help please?

I have installed gnome-weather: sudo apt install gnome-weather Menu--Accessories--Weather can launch it. Is there a way to set it on the bottom panel of lxde?

Under LXDE desktop manager Alt+F11 can be used to switch a program to full screen. I use this shortcut so often that'd I rather have certain programs always open in full screen instead of doing it manually. Is it possible to define some system configuration, or a shell script that'd always launch particular programs in full screen? (Particular not all because I wouldn't want certain small windows like network configuration window and system calendar to open in full screen).

I am using Debian 8.6 LXDE on a Powerbook G4 15" 1.67GHz and would like to enable tap to click on the touchpad. It is already double scrolling but tap to click would help to save the ageing mouse button. Two fingered tap for left click would be the icing on the cake, is this possible?

I'm booting Sparkylinux from a live-usb in a notebook with broken screen. There is a external monitor connected by VGA. The external monitor is booted dual with the notebook monitor And the external monitor resolution is booted with some issues. To fix it i need to put the external monitor as the primary monitor, or even better, shutdown the notebook monitor. In Ubuntu i can use Fn key to change monitors. In Lubuntu, even i cant see much, i can open the start menu, type monitor and change it manually. In Sparkylinux the special key dosen't work and start menu is tricky, so i cant access the monitor menu whithout seeing. So I'm trying xrandr to change it , but apearently i cant open the terminal ( ctrl+alt+t), the bad resolution sends it to another realm. So i used ctrl+alt+F1 to try xrandr, but for most but not all xrandr commands i get "xrandr: Cant open display". Like xrandr --listmonitors

Upon running sudo apt remove xscreensaver I am prompted with the below messages. Is this normal? Should I proceed? Why would removing a screensaver involve so many things? I'm using LXDE desktop, by the way, can I safely remove lubuntu-desktop?
