我在旧的 HP Proliant ML110 G5 上安装了适用于 x64 系统的 Ubuntu Dekstop 20.04.1 LTS。它工作得很好，因为它可以识别磁带驱动器和嵌入式 SATA raid 控制器，但在登录屏幕期间，系统非常非常滞后；不过我登录后，系统运行良好，很流畅。这不是一个大问题，但很烦人，我想知道如何解决它。的输出lspci命令是：

答案1
我解决了这个问题。我了解到问题的原因是图形芯片 MGA G200e。我通过以下命令安装了驱动程序：
sudo apt install xserver-xorg-video-mga
然后我修改了/etc/gdm3/custom.conf#WaylandEnable=false文件，我取消注释删除字符的行
#。
最后我重新启动了机器。
