Dell Precision 5530 上的 Ubuntu 19.04 出现屏幕撕裂/故障

Dell Precision 5530 上的 Ubuntu 19.04 出现屏幕撕裂/故障

我目前在 Dell Precision 5530 笔记本电脑上运行 Ubuntu 19.04。我已从 Linux Mint 切换到 Ubuntu,希望 Linux 中的屏幕撕裂现象能够停止,但随着时间的推移,它又开始重新出现。

屏幕会出现故障、冻结和撕裂,而不仅限于任何特定的应用程序。

我尝试创建一个 /etc/X11/xorg.conf.d/20-intel.conf 文件,但当我重新启动时,我会陷入登录循环。

我该怎么办?我正绞尽脑汁寻找解决这个问题的方法。
