我遇到了以下问题:我的笔记本电脑已挂起并通过 Thunderbolt 连接到扩展坞。当我按下某个键唤醒笔记本电脑时,外接显示器(通过扩展坞连接)打开,一切正常。然后,几秒钟后,它短暂变黑,然后再次打开,但这次出现了屏幕撕裂。我在日志中发现以下消息:

其中一行写着“禁用 TearFree”,所以它可能与此有关。有人知道我该如何解决这个问题吗?这是 autorandr 的计时问题吗?我可以提供其他有用的信息吗?
(我可以通过在不同的 autorandr 配置之间来回切换一次来解决撕裂问题。但这真的很烦人......)
答案1
添加Option "TripleBuffer" "true"
英特尔驱动程序配置文件20-intel.conf
似乎可以解决该问题。
编辑:这似乎没有完全解决问题。这有帮助,但在暂停系统后,我仍然经常遇到屏幕撕裂的情况。
