比较麻烦</del> 不喜欢用 Windows 办公且喜欢折腾，所以很早之前就把公司的笔记本电脑装了 Linux 在日常使用。</p> <p>之前使用的发行版是 Linux Mint，其实基本上都能满足需求：美观程度、软件兼容性等，但是不知道为什么钉钉开会看不到别人共享的屏幕。想着既然已经折腾了，干脆去找其他发行版试试，结果不小心跳了更大的坑。</p> <p>一开始选了Pop!_OS，但是风格不是很喜欢，并且无法打开钉钉，就很快放弃了，转向了 Kubuntu，本来以为问题都是基于 Ubuntu 的发行版引入的，Kubuntu 基本就是 Ubuntu 总没问题吧？结果发现自己大错特错。</p> <p>TL;DR: 问题不是发行版导致的，而是 glibc 2.41+ 和 Linux 内核新特性共同作用 及 Wayland 显示协议导致的。</p> <h3 id="无法启动">无法启动 </h3> <p>首先无法启动，点击应用后没有反应甚至没有报错。通过检索找到了<a class="link" href="https://xingwangzhe.fun/posts/dingtalk-linux-fix-execstack/" target="_blank" rel="noopener" >这篇 Blog</a>，按所述方法修复后能正常启动了。</p> <p>Blog 中推荐的方案一用的是 execstack，但是实际上新系统中已经没有这个工具了，所以使用了方案二的 patchelf。</p> <h3 id="无法打开会议">无法打开会议 </h3> <p>正常打开后发现点击会议没有反应，为了查看日志，到应用目录下手动执行了启动脚本 sh，然后将相关日志喂给了 DeepSeek：</p>

是一样的：手动移除相关文件（<code>libconference_new.so</code>）的可执行栈标记。</p> <h3 id="无法共享屏幕">无法共享屏幕 </h3> <p>这个相比前两个原因“简单”一点，不涉及 Linux 的安全机制，“只”是钉钉没有适配 Wayland 协议而已，但是解决起来就很麻烦。因为 AI 会选择最“正确”的那个解决方案：不要用 Wayland……</p> <p>最后还是自己检索找到了一个第三方的补丁：<a class="link" href="https://github.com/lzl200110/dingtalk-wayland-screenshare" target="_blank" rel="noopener" >dingtalk-wayland-screenshare</a>。手动执行编译（中间反复报错→喂给 AI →安装依赖→报下一个错……）后得到一个用于实现 hook 逻辑的 so 文件，根据说明修改了钉钉的启动脚本，把它塞到了 LD_PRELOAD 中，最后一切正常了。</p> <hr> <p>以上一堆问题解决下来，发现其实保持最开始老老实实用 Mint 就能避免大部分问题：Linux 内核更新没那么激进 &amp; 桌面协议还是 X11，等 Mint 都更新了钉钉应该也适配了。结果现在费时费力还要重新配置 keyd、输入法、指纹识别等一堆东西……</p>
