我在使用 Radeon HD 8670 卡让专有 AMD 显卡驱动程序在 RHEL 6.9 上运行时遇到问题。
输出来自lspci | grep -i VGA：
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland XT [Radeon HD 8670 / R7 250/350] (rev 83)
如果我设置export LIBGL_DEBUG=verbose并运行glxgears，我会得到以下输出：

为什么显卡驱动程序不工作？
答案1
专有的 AMDGPU-PRO 驱动程序仅支持新卡，其中似乎不包括您的 Radeon HD 8670。
打开的驱动程序缺少库（显然）。我能想到的唯一两个解决方案是：
- 重新安装驱动程序，和/或
- 下载并安装可能包含必要文件的所有软件包
就我个人而言，我会从选项 1 开始。
如果这两项都失败了，按照可能性的顺序：
- 这两个驱动程序完全不支持您的 GPU
- 您的 RHEL 安装已损坏
- RHEL 整体已损坏
对于第一个，请查看更改 /etc/X11/xorg.conf 以使用较旧的 radeon 驱动程序之一（ati、radeohd 等）
对于后两个，请提交错误报告
