在我的 lubuntu 24.04 上，我有一个小的 / 文件系统，因此我会不时检查是否有足够的可用空间。

为此我使用

sudo du -xh -d 3 / | sort -h -r | egrep -v '*M|*K'
grep: warning: * at start of expression
grep: warning: * at start of expression
27G     /
12G     /var
10G     /var/cache
9,8G    /var/cache/apt
9,6G    /usr
6,0G    /usr/lib
5,6G    /boot
2,8G    /boot/ubuntu-20.10
2,5G    /boot/bullseye
2,2G    /usr/share
1,9G    /usr/lib/x86_64-linux-gnu
1,7G    /var/lib

这不是我的空间消失了的问题，我无法弄清楚警告是什么意思以及如何避免它。

我正在运行 Lubuntu 22.04。对于 PS4，我在带有 exfat 文件系统的 USB 驱动器上创建；我不记得它是与较新的 exfatprogs 还是与较旧的 exfat-utils 一起使用的。

问题：

显示我用来创建它的文件系统的转储。

我想给 exfat 文件系统一个标签，但我不知道我是否必须使用tune.exfat或exfatlabel- 或者我使用哪个无关紧要？

我将尝试在 lubuntu 20.04 中向我发送短信提醒。我的自动启动 ($HOME/.config/autostart) 中有 2 个有效，第二个无效。

工作执行放置在 /usr/local/bin/ 中的 bash-skript 第二次我在 $HOME/.config/autostart/ 下创建一个桌面文件

cat .config/autostart/firefox-hold.desktop 
[Desktop Entry]
Exec=/usr/bin/notify-send "firefox auf hold gesetzt"
Name=firefox-hold
Type=Application
OnlyShowIn=LXQt;
Version=1.0

我激活它

lxqt-config-session

查看 .xsession-errors

+ /usr/bin/notify-send -i /usr/share/icons/gnome/48x48/status/dialog-warning.png Warnung 'home voll' # the working one

从第二

notify-send \"firefox auf hold gesetzt\" #looks strange

在终端中，该命令notify-send "firefox auf hold gesetzt"有效。

操作系统=lubuntu 20.04。我将升级到 22.04（不是问题）我想备份我的 $HOME，但有些文件不属于我的用户

是否可以将 find 的输出提供给 rsync 并让他排除它？

我的英语不足：

find $HOME -not -user $USER
/home/alex/initrd.img-5.3.0-53-generic
/home/alex/backup/restricted.pref
skip

我可以以某种方式以这种形式将其提供给 rsync 吗？就像从文件中一样？

rsync someoption --exclude /path/to my exclude file

我不知道如何排除文件和文件夹，但如果没有必要，我有点懒惰地更改我的备份脚本。

我正在使用 sddm 作为显示管理器运行 lubuntu 20.04。

每当我通过 gui 注销并以其他用户身份登录时，用户会话都不会被杀死（不知道它是否是设计使然）。所以 loginctl 为我的用户显示了双重会话。

我杀死的 2. 用户的所有会话

killall -u second_user_name

对于我的主要用户 3 个会话仍然存在。

我可以删除的具有最低会话 ID 的会话

sudo loginctl kill-session 3

剩饭剩菜

loginctl list-sessions 
SESSION  UID USER SEAT  TTY
     11 1000 alex seat0

     11 1000 alex seat0

How can I get rid of it? Or avoid this situation (more than one session per user)

我用这个script工具做了一个终端记录。

mediainfo video 
General
Complete name                            : video
File size                                : 1.29 KiB

我可以玩它scriptreplay。是否可以将其转换为 GIF，例如使用ffmpeg或其他程序？

澄清一下，我script的意思是来自bsdutils包，而不是程序脚本。我认为保存的文件是一种视频，所以我可以 grep 一些帧/图片并创建一个 GIF。

我希望现在更清楚了。

我在 Lubuntu Focal 上。

Hardwaretime 显示正确，但在我的桌面上时钟是 2 小时后。

hwclock --verbose

与timedatectl：

              NTP service: inactive                   
          RTC in local TZ: no

重新配置 tzdata 没有帮助；时区设置正确。

也试过：

timedatectl set-local-rtc 0

..没有帮助，但也许我理解手册页错误。

核心：

uname -r

我正在运行 lubuntu 20.04。

debian 和 ubuntu 中的用户名和 (id/gid) 相同。我可以将 ubuntu $HOME 中的 mv 或 cp 文件绑定到文件夹。

我不确定，如果我犯了错误，或者脚本本身有问题。

我正在运行 lubuntu 20.04（从 19.04-->19.10 升级）我的网络连接最多的时间是来自邻居的来宾帐户。信号有时很弱，我失去了连接；然后通知守护进程给了我一个气泡。当我看视频时，这很烦人。我将尝试通过排除 nm-tray 和 NetworkManger

lxqt-config-notificationd

并在文件中

$HOME/.config/lxqt/notifications.conf

但我不知道如何使它正确。

这是在我从 gui 前端尝试之后。

cat .config/lxqt/notifications.conf 
[General]
__userfile__=true
blackList=nm-tray, "  NetworkManager"
server_decides=5
spacing=6
unattendedMaxNum=10
width=300

它看起来我错了。

注意：升级到 lubuntu 20.04 后。我将配置更改为

cat .config/lxqt/notifications.conf 
[General]
__userfile__=true
blackList=nm-tray, NetworkManager
placement=top-right
server_decides=5
spacing=6
unattendedMaxNum=10

好的，我知道这是提议的，通常我可以处理它。但是我没有看到 linux-image 和 Thunderbird 以及其他软件包之间的联系。

请注意，这是全新安装的 ubuntu disco。没有ppa。没有按扣/扁平包装。

我想在 ubuntu disco 中使用 smartctl 测试 USB 硬盘。

我从smartmontools.org/wiki/获得的选项 -d usbjmicron

lsusb | grep -i micron

smartctl --scan 也显示了它

一段时间后，fdisk 和 parted 挂起。
