opengl/glx 核心轉儲 - 通用 intel linux 驅動程序，RHEL6
最近，我從使用專用 ATI 顯卡和專有驅動程序切換到板載 Intel 顯卡和預設/通用 Intel 驅動程序，因為 ATI 顯卡已損壞，我無法讓專有驅動程序與我的 X 伺服器很好地執行。
無論如何，現在每當使用 OpenGL 的程序執行時，我都會得到核心轉儲。例如：

編輯：我剛剛注意到
Module glx: vendor="Advanced Micro Devices, Inc."我的 xorg 日誌中的行。我注意到該文件的最後修改時間是相當近的——大約在我安裝 ATI 影片驅動程序的時候。當我安裝專有的 ATI 驅動程序時，這個庫是否可能被破壞？
我想到了。正如我所懷疑的，AMD 想要使用的共享庫與 Intel 驅動程序使用的共享庫之間存在衝突。解決方案是解除安裝 AMD 驅動程序。我通過在
/usr/share/ati. 在我執行這個腳本之後，我不得不恢復我/etc/X11/xorg.conf一直在使用英特爾驅動程序的那個，因為解除安裝腳本試圖破壞它。
