总的来说,我对Lubuntu和Linux很陌生。
我试图通过安装Ubuntu18.04 x64来恢复一台旧的戴尔x64笔记本电脑。
我已经解决了一些问题,但我仍然很痛苦的启动时间非常缓慢和缓慢的简历暂停。该设备有一个SSD,所以我不认为它应该需要几分钟来启动,因为它正在做的。

如戴尔D 630上自18.04安装以来启动时间缓慢中所提议的
我将GRUB_CMDLINE_LINUX_DEFAULT行在/etc/default/grub中更改为:
GRUB_CMDLINE_LINUX_DEFAULT="video=SVIDEO-1:d"运行sudo update-grub。
现在我的启动时间大约是30秒:
