我今天从软件更新中心安装了最新更新(我在ubuntu显示通知时进行更新),重新启动了计算机,现在无法正常启动。我可以得到的最佳屏幕显示在下面。如果我调整屏幕大小,则会变成黑色。如果我重新启动机器,则它只会显示紫色。
请注意,该屏幕无响应,我无法在其上单击任何内容。
除了SMBus Host Controller not enabled!
我没有看到其他警告。请注意,我不知道更新之前是否存在此警告。
我正在vwmare工作站15播放器(最新更新)中运行ubuntu 18.04。关于如何开始调试的任何想法?

Update: Blacklisting i2c-piix4
according to this answer removed the warning but didn't fix the issue.
Update: The answer from Uzair helped me log into the account (run dpkg and update grub from recovery mode).
Answer: This answer helped me fully to resolve the issue. I don't understand the fix. If anyone does, put it as the answer and I'll mark it as such.
Regarding duplicity: The answer from another question did solve my issue but I don't think my question is a duplicate of that one. I began with a fresh install of 18.04 a few months ago, did several updates without an issue and only today experienced issues which are different than those described in the other question. I think we experienced different bugs with wayland and we both solved it by disabling it which is a destructive solution applicable to many questions.
The issue is with Wayland. While Ubuntu defaults to an X11 session, for some reason they left it enabled for GDM.
You can certainly replace GDM with LightDM, but an easier option would be to:
sudo nano /etc/gdm3/custom.conf
Then change the line:
#WaylandEnable=false
to
WaylandEnable=false
Press Ctrl+O and then Ctrl+X and reboot. If you don't wish to reboot you can do
sudo systemctl restart gdm
这将重新启动Windows会话(假定ssh进入了上述修复框)。
