# Python backtrace

已尝试重新安装Radeon驱动，但问题未解决；启动3D游戏时也会崩溃。

从崩溃日志可见libLLVM-15.so与libLLVM-16.so同时被调用，这是Arch滚动更新中常见的LLVM版本冲突问题，导致显卡驱动相关组件依赖不匹配。

修复步骤： #

1. 清理残留的旧版本LLVM包
   先查看已安装的LLVM相关包：

   pacman -Qs llvm
   

   卸载所有低于当前稳定版的LLVM包（例如llvm15系列）：

   sudo pacman -Rns llvm15 llvm15-libs
   

2. 强制重新安装显卡相关组件，确保依赖版本统一

   sudo pacman -Syu mesa lib32-mesa vulkan-radeon lib32-vulkan-radeon amdvlk lib32-amdvlk
   

3. 重建系统库缓存

   sudo ldconfig
   

4. 验证修复效果
   重新启动Blender或3D游戏测试；也可通过以下命令确认LLVM版本一致性：

   ldd /usr/bin/blender | grep llvm
   

   输出应仅显示同一个大版本的LLVM库。

若上述步骤无效，可尝试清理Blender配置文件后再测试：

mv ~/.config/blender ~/.config/blender.bak
