前因

某个闲暇的下午，我打开了steam，用鼠标划过库目录，两眼一亮。“是你！天际线！”我惊呼着，点击“开始游戏”

加载新游戏的时候就…

当机立断

机智的我立刻用coredumpctl查看崩溃dump

其中不难发现这个crash是由$HOME/.local/share/Steam/ubuntu12_32/../ubuntu12_64/vulkandriverquery引发的，于是我就手动运行单独了一下它，结果输出了DRM版本过低的消息，然后我便开始了四方查阅

后果

查阅到的原因是因为linux内核中的radeon模块所使用的是DRM 2.*，无法满足vulkandriverquery的要求，那怎么办啊，我这可是老显卡(R9 270 Southern Island)，又是一波猛如虎的操作，我将目光投向了那边实验性支持SI指Sounthern Island的amdgpu驱动或者可以索性将vulkan全套东西删掉？没试过

ArchWiki上有指南，我就不造轮子了 传送门

最后完美运行ExcellenXD!
