我的显示屏在 60 分钟后关闭。
我的电脑是 HP Pavilion h8-1234。我有 Windows 7 和 Linux Mint 13 的双启动设置。
我用新的 Radeon R7 260x 显卡更换了旧显卡。我通过以下链接安装了 AMD 显卡驱动程序：http://support.amd.com/en-us/download/desktop?os=Linux%20x86_64。在视频需求量很大的情况下，我可以在 Windows 操作系统上运行几个小时。然而，当我在 Linux Mint 操作系统上运行显卡时，显示器在进入桌面会话大约 60 分钟后崩溃。一旦显示器崩溃，我就无法使用++Ctrl访问终端控制台来执行软关机。AltF2
我该如何解决显示崩溃问题？
下面是崩溃前的xserver日志文件
