fedora 34 开启 vncserver 服务
<p>最近重新用回了fedora, 现在已经是34版本了。启用vncserver 时，提示已经变成了一个服务；之前一直使用 vncserver :1 的形式启动；</p><p>现在建议直接使用 systemctl 进行管理，我想这样可能更具兼容性吧。肯定开发人员，对这种原生支持的方式进行了进一步优化。</p>
<p>所以我建议使用systemd的形式进行启动vncserver。</p>
<p><strong>使用方式：</strong></p>

<p>之后使用客户端进行连接就好；</p>
<p>通过使用，发现使用 vncserver :1 启动的远程桌面会使用最新的gnome桌面，最新的桌面具有锁屏的bug, 在锁屏之后不能被打开。而使用systemd启动的vnc服务，则使用了低版本的gnome的主题避开了这个问题，可以正常使用。我觉得这应该是系统开发人员的在项目适配之间的一种 tradeoff 吧。</p>
