我在 Ubuntu 18.04 上的视频播放性能很差，我想更新我的集成 Intel UHD Graphics 620 卡的驱动程序。但是，我不太清楚该怎么做。查看输出，apt show xserver-xorg-video-intel我得到以下内容：

Description: X.Org X server -- Intel i8xx, i9xx display driver
This package provides the driver for the Intel i8xx and i9xx family
of chipsets, including i810, i815, i830, i845, i855, i865, i915, i945
and i965 series chips.
.
This package also provides XvMC (XVideo Motion Compensation) drivers
for i810/i815 and i9xx and newer chipsets.
.
This package is built from the X.org xf86-video-intel driver module.
.
The use of this driver is discouraged if your hw is new enough (ca.
2007 and newer). You can try uninstalling this driver and let the
server use it's builtin modesetting driver instead.
让我困惑的是上面输出的最后一段，其中指出
The use of this driver is discouraged if your hw is new enough (ca.
2007 and newer). You can try uninstalling this driver and let the
server use it's builtin modesetting driver instead.
因此，我想问以下问题：
- 为什么 Ubuntu 18.04（已有 3 年历史的操作系统）附带的英特尔显卡驱动程序适用于超过 14 年的显卡，而默认情况下似乎不支持较新的显卡？
- 有没有办法安全地安装最新的英特尔显卡驱动程序？查看“软件和更新”应用程序中的“其他驱动程序”选项卡，我似乎无法更新我的英特尔驱动程序。
- 从输出中读到最后一段
apt show xserver-xorg-video-intel似乎意味着我可以简单地使用sudo apt remove xserver-xorg-video-intel。这会删除旧的英特尔显卡驱动程序并自动安装最新的驱动程序吗？ - 最后一个问题：模式设置驱动程序到底是什么？
非常感谢。
