我在使用 Radeon HD 8670 卡讓專有 AMD 顯示卡驅動程式在 RHEL 6.9 上運行時遇到問題。
輸出來自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)
如果我設定export LIBGL_DEBUG=verbose並運行glxgears，我會得到以下輸出：

上述輸出是從執行 X-Win32 的 Windows PC 遠端登入系統時獲得的。在系統控制台上，通常的 GUI 登入畫面不會出現在預設 TTY 上。當切換到其他 TTY 之一（Ctrl + Alt + F2等）時，會顯示通常的純文字終端登入畫面。

為什麼顯示卡驅動程式不工作？
答案1
專有的 AMDGPU-PRO 驅動程式僅支援新卡，其中似乎不包括您的 Radeon HD 8670。
打開的驅動程式缺少庫（顯然）。我能想到的唯一兩個解決方案是：
- 重新安裝驅動程序，和/或
- 下載並安裝可能包含必要文件的所有軟體包
就我個人而言，我會從選項 1 開始。
如果這兩項都失敗了，按照可能性的順序：
- 這兩個驅動程式完全不支援您的 GPU
- 您的 RHEL 安裝已損壞
- RHEL 整體已損壞
對於第一個，請查看更改 /etc/X11/xorg.conf 以使用較舊的 radeon 驅動程式之一（ati、radeohd 等）
對於後兩個，請提交錯誤報告
