我的 Ubuntu 系统 GUI 变得非常慢。不知道原因是什么。
问题可能出在显卡驱动程序上。我该如何解决?
glxinfo | grep Mesa
client glx vendor string: Mesa Project and SGI
OpenGL core profile version string: 3.3 (Core Profile) Mesa 18.0.0
OpenGL version string: 3.0 Mesa 18.0.0
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 18.0.0.
我全新安装了 Ubuntu 18.04.3 64 位。以为这可以解决问题,但事实并非如此。
系统在双启动下运行,Windows 10 和 Ubuntu 18.04。
安装完 Ubuntu 后,当我尝试登录时,UI 冻结。我不得不按照上述说明操作这里获取登录后信息。但 UI 太滞后,无法使用。
输出:
