我刚刚安装kde-full并在安装后选择sddm作为显示管理器，但我没有注销并将桌面环境更改为 KDE 并重新启动，现在当我启动我的 Ubuntu 时我看到黑屏。

几天前更新后，Okular（我使用一段时间后一直很顺利）在打开时停止显示任何窗口。停靠栏和活动进程列表显示该程序正在运行。这种情况发生在程序打开和关闭几次之后。重新启动计算机没有帮助。如果我卸载并重新安装，我会在几个会话中恢复正常运行，然后行为会恢复。有没有人遇到过类似的事情，有谁知道发生了什么？我正在运行 Ubuntu 24.04，Okular 版本是 24.05.1。从命令行，我可以生成以下对话框。

$ okular (一些 PDF 文件)
kf.windowsystem: static int KX11Extras::currentDesktop() 只能在 X11 上使用

** (okular:(进程 ID)): 警告 **: (时间戳): atk-bridge: get_device_events_reply: 未知签名

在我按 ^C 中断之前没有发生任何其他事情。仅输入

$ 奥克拉尔

只会出现警告。不会出现任何程序窗口。

我在更新 Ubuntu 时遇到了问题。证书验证失败，于是上网查找。然后根据我自己的逻辑和一些论坛上的一些答案。我运行了以下命令：

sudo apt autoremove ca-certificates

现在，重新启动电脑后，我看到的是 tty1 屏幕，而不是正常的登录屏幕。我多次尝试按键盘组合 Ctrl+Shift+F7-或-F8。有谁知道这是什么以及如何解决它？

我正在使用 Ubuntu 和 KDE Plasma Desktop 全套套件。我已经卸载了 GNOME。

尝试后

sudo apt update && sudo apt install ubuntu-desktop

这就是我得到的：

我刚刚在我的笔记本电脑上安装了 Kubuntu，一切运行顺利。然后plasma-discover突然停止工作。当我尝试启动它时，窗口在左上角显示为一个小矩形一秒钟左右，然后立即消失。从命令行启动它，会给出相同的结果，并显示以下消息：

我做了一些研究，也许它与一些键绑定有关，但我不知道如何解决这个问题......我的plasma-discover版本是5.24.7，我在6.5.0-15-generic x86_64内核上运行 Kubuntu 22.04

我通过快速创建安装了 Ubuntu 22.04，Gnome 一切正常。不过，我想切换到 KDE 并安装它，而且它在 Hyper V 本地模式下运行良好。但是，如果我通过 XRDP 连接，则仍然使用 Gnome。我更改/etc/xrdp/startwm.sh并注释掉了最后两行并添加了exec startkde：

#test -x /etc/X11/Xsession && exec /etc/X11/Xsession
#exec /bin/sh /etc/X11/Xsession
exec startkde

但是，这不起作用，在本地模式下，我可以在以下位置看到这些错误/var/log/xrdp.log：

[20231017-13:52:43] [ERROR] xrdp_sec_recv: xrdp_mcs_recv failed
[20231017-13:52:43] [ERROR] xrdp_rdp_recv: xrdp_sec_recv failed

我还找到了如何配置 XRDP 以启动 cinnamon 作为默认桌面会话并尝试

echo "startkde" > ~/.Xclients

chmod u+x ~/.Xclients

sudo systemctl restart xrdp.service

然而这也行不通。怎么了？

刚刚看到该/etc/xrdp/startubuntu.sh文件，看起来也应该更改：

#!/bin/sh
# DESKTOP_IMG: This file was created/modified by the Desktop Image build process
export GNOME_SHELL_SESSION_MODE=ubuntu
export XDG_CURRENT_DESKTOP=ubuntu:GNOME
exec /etc/xrdp/startwm.sh

我尝试过

export KDE_SESSION_VERSION=5
export DESKTOP_SESSION=plasma
export XDG_CURRENT_DESKTOP=KDE
exec /etc/xrdp/startwm.sh

然而仍然不工作。

在 KDE Plasma 上，Konsole 没有外观选项...我希望 Konsole 有一个半透明的背景，因为我使用的是 neovim，并且在我的终端后面有文档在如此小的单显示器设置中非常重要。

我的 Ubuntu Studio 安装上的任何 KDE su 提示似乎都无法正常工作。我已经通过终端为root帐户设置了密码，并通过这样的终端成功以root身份登录......

su
{enter password}

一切都很好

但是从图形上看，我被卡住了-我发现的唯一解决方法是su在终端中，然后手动执行命令。

我怎样才能解决这个问题？我正在尝试设置一些我目前无法设置的东西，而不得不通过挖掘来查找文件。

尝试更新 MariaDB

我读到，我应该更新 MariaDB，但我不知道如何。

~$ sudo systemctl restart mariadb
Failed to restart mariadb.service: Unit mariadb.service not found.
~$ sudo mysql_upgrade
Reading datadir from the MariaDB server failed. Got the following error when executing the 'mysql' command line client
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
FATAL ERROR: Upgrade failed

sudo: mariadb-upgrade: Command not found
~$ mariadb --version
mariadb  Ver 15.1 Distrib 10.3.34-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

然后我跑了

curl -LsS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash -s -- --mariadb-server-version=10.8
sudo apt update && sudo apt upgrade -y
~$ mariadb --version
mariadb  Ver 15.1 Distrib 10.3.34-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

但正如人们所看到的，这并没有太大变化。

我读到https://bbs.archlinux.org/viewtopic.php?id=184192，更新到 MariaDB 版本 10 可能是问题所在。它建议降级，然后做一些事情，然后再次升级。但是，那篇文章是 2014 年的，所以我不确定它是否仍然适用。

应用装甲

根据升级到 Ubuntu 20.04.2 LTS 会破坏 Akonadi，因此 KMail可能是 apparmor 的问题，所以我跑了

sudo systemctl disable apparmor

并重新启动，但这并没有帮助。

我能做些什么？
