在 17.04 上暂停不适用于 gnome 和 gdm3

Question

升级到 Ubuntu 17.04 并切换到 gnome-desktop 和 gd3m 后，挂起不再起作用。当尝试暂停显示黑屏但在费用秒（1-2s）后登录屏幕再次出现，但在这种情况下登录屏幕不起作用，因为当输入密码并按回车键再次出现登录屏幕时，没有在桌面登录。那么此时需要重启。以下是我在尝试挂​​起时在 syslog 中找到的日志：

进行的测试：

• [失败] 使用清除但没有重新安装 gdm3，暂停不起作用。
• [失败] 重新安装 Nvidia 驱动并测试多个版本
• [失败] 使用 X.Org Nouveau 显示驱动程序进行测试
• [失败] apt-get 升级
• [OK] 将显示管理器切换到 lightdm 并且挂起工作正常。

在这一点上，我找到的唯一解决方案是切换到 lightdm 显示管理器，但对我来说不是一个真正的解决方案。请任何建议或帮助？

Answer 1

您可能应该切换到 lightdm。

我在 Ubuntu 17.04 中也遇到了 gdm 问题，主要是登录问题。我必须进入恢复模式并使用 dpkg 将其改回 lightdm。

这可能是因为在 ubuntu 17.04 中从 unity 到 gnome-shell 的过渡只是部分的。
