          我在系统中使用想开机自启动一个QT程序,我沿用了树莓派的方法,在~/.profile文件中添加了我的启动路径,但是程序并没有像树莓派一样启动,传统的自启动程序会进入桌面再启动程序,效果会差很多时间也长很多,还有就是开机的动画能不能有个教程,如果太忙了就算了,希望能回答我第一个问题

              @大法师 配置就是在~/profile文件末尾加上 echo “coolpi” | sudo -S /home/coolpi/qt5/demo ,这是启动程序的命令,树莓派跟我以前用的ROCKPI正常是能启动程序的,在界面出来以前,你看到的效果就是黑屏然后直接进入了我们的程序,demo可以随便写一个QT demo,然后开机重启的时候看能不能在进入界面之前启动

                这是阻塞系统运行?还是后台运行作为开机动画?

                我试了分别在/etc/profile、/home/coolpi/.profile文件尾增加qt demo是可以的

                sudo apt install qtbase5-examples
                
                coolpi@coolpi:~$ cat /etc/profile
                # /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
                # and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
                
                if [ "${PS1-}" ]; then
                  if [ "${BASH-}" ] && [ "$BASH" != "/bin/sh" ]; then
                    # The file bash.bashrc already sets the default PS1.
                    # PS1='\h:\w\$ '
                    if [ -f /etc/bash.bashrc ]; then
                      . /etc/bash.bashrc
                    fi
                  else
                    if [ "`id -u`" -eq 0 ]; then
                      PS1='# '
                    else
                      PS1='$ '
                    fi
                  fi
                fi
                
                if [ -d /etc/profile.d ]; then
                  for i in /etc/profile.d/*.sh; do
                    if [ -r $i ]; then
                      . $i
                    fi
                  done
                  unset i
                fi
                
                #echo "coolpi" | sudo -S /usr/lib/aarch64-linux-gnu/qt5/examples/gui/analogclock/analogclock
                coolpi@coolpi:~$
                
                coolpi@coolpi:~$ cat ~/.profile 
                # ~/.profile: executed by the command interpreter for login shells.
                # This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
                # exists.
                # see /usr/share/doc/bash/examples/startup-files for examples.
                # the files are located in the bash-doc package.
                
                # the default umask is set in /etc/profile; for setting the umask
                # for ssh logins, install and configure the libpam-umask package.
                #umask 022
                
                # if running bash
                if [ -n "$BASH_VERSION" ]; then
                    # include .bashrc if it exists
                    if [ -f "$HOME/.bashrc" ]; then
                        . "$HOME/.bashrc"
                    fi
                fi
                
                # set PATH so it includes user's private bin if it exists
                if [ -d "$HOME/bin" ] ; then
                    PATH="$HOME/bin:$PATH"
                fi
                
                # set PATH so it includes user's private bin if it exists
                if [ -d "$HOME/.local/bin" ] ; then
                    PATH="$HOME/.local/bin:$PATH"
                fi
                
                echo "coolpi" | sudo -S /usr/lib/aarch64-linux-gnu/qt5/examples/gui/analogclock/analogclock
                coolpi@coolpi:~$
                

                因为不是后台运行,重启后会阻塞桌面系统显示窗口。此时可以通过键盘ctrl+alt+f6切换到终端命令行进行恢复修改操作。

                也可以后台运行测试

                vim ~/.profile
                ...
                echo "coolpi" | sudo -S /usr/lib/aarch64-linux-gnu/qt5/examples/gui/analogclock/analogclock &

                  @大法师 感谢您的回答,您的操作看起来很正常,这样看来确实很奇怪,但我这边不论是ubuntu22还是ubuntu20我在.profile文件下启动我的qt程序都没反应,它会直接进入桌面,而在/etc/xdg/autostart/下可以自动启动我的应用程序,但是后者显示屏会出现几秒钟的ubuntu图形界面,这看起来很糟糕!

                    百度网盘或onedrive有最新镜像,是否镜像不一致?

                      @大法师 前天刚刷的最新镜像,甚至于我在使用ssh登陆时都能启动程序,终端登陆就会启动程序,但是显示屏上就是直接进入了桌面。

                        是不是自动登陆设置打开了?

                            @大法师 关了也没用,换了一个最简单的demo也没用,我只能通过我原来的方法启动程序,然后把整个桌面服务关了试试看了,不过这样启动会慢很多

                              @Twsuts 看看登录服务用的是什么gdm还是LightDM,改那个的配置文件。不启动桌面启动你的QT程序
