17.10至18.04在启动期间冻结升级

Question

我只是拿了一台工作网关P4桌面电脑，并将它从16.04LTS一路升级到17.10，没有任何问题。当我试图安装18.04LTS时，我的引导就有问题了。

我以许多不同的方式重新安装，但在引导问题上没有任何改进。Ubuntu的标志出现，点闪烁几次，然后鼠标指针冻结，系统是完全没有反应。如果我用从grub内核行中删除的“静音启动”启动，我可以看到它在启动第一个用户帐户120后不久就停止了。

这里有条线索..。如果我用nomodeset替换“静音启动”，它会完全启动，但它只处于640x480模式。

这是i915的视频信息..。

我怀疑我需要在grub中添加一个特殊的i915视频控制器内核参数，以使视频正常工作。关于那个参数可能是什么..。或者其他的想法？

更新1:我刚刚发现，如果我启动到“恢复模式”，然后选择“恢复正常启动”，它完全启动，一个1024x768 4:3 (应该是16:9)桌面。

更新2:从17.10升级到18.04，引导失败。重新安装18.04，引导失败。磁盘分区删除和清理18.04，引导失败。安装18.04“建议”软件，引导仍然失败。运行良好。

更新3:我找到了一个i915参数列表..。

更新4:我目前正在我的grub内核行中运行i915.modeset=0，它正在引导，我得到了1024x768 (4:3)。

更新5:更新到内核4.16.9并没有解决问题。

更新#6：@卡雷尔的部分回答提供了一个足够好的解决办法。从gdm3显示管理器切换到轻型显示管理器工作。然后，我也可以从我的grub内核行中删除i915.modeset=0。

sudo apt-get update
sudo apt-get install lightdm
# if lightdm wasn't already installed, it'll ask which dm you want
# if lightdm was already installed, then you need to:
sudo dpkg-reconfigure lightdm
# and choose lightdm over gdm3
reboot

更新#7:

结果发现这个问题不是gdm3和lightdm的问题。这是旧的英特尔GPU的gdm3 3/wayland的问题。

在terminal..。

• cd /etc/gdm3 #更改目录
• sudo pico custom.conf #编辑此文件

查找和改变：

#WaylandEnable=false

对此：

WaylandEnable=false

保存文件。

• sudo dpkg-reconfigure gdm3 #选择gdm3 DM

选择gdm3和OK。

• reboot #重新启动计算机
