我从 Ubuntu 20.04 更改为 24.04。现在时钟显示错误的时间（早了 3 个小时）。当我打开系统设置来修复此问题时，单击“日期和时间”时程序崩溃。有人能帮帮我吗？

我正在尝试在一台新的 Ubuntu 24.04 机器上安装 postgresql。令我惊讶的是，

Package postgresql is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'postgresql' has no installation candidate

据我所知，这个包应该可用，上面的情况是意料之外的。我肯定做了一些事情弄乱了我的计算机，但我不确定是什么。任何帮助都非常感谢。

罗技 G915 (TKL 键盘)

所以，故事是这样的：我通过“特殊”程序（而不是 gnome，如 autokey 和其他程序）调整键盘配置，现在功能键不再起作用了……

  • 我尝试重置键盘配置、布局、一切……

  • 我已经尝试过dconf reset -f /org/gnome了dpkg-reconfigure keyboard-configuration

现在我要让 FN 键再次工作的唯一解决方法是：

  1. 登录到第二个用户（之前创建的、未动过的、未使用过的用户），该用户仍可使用 FN 键，
  2. 注销，
  3. 切换回我的用户。

瞧，这就是让它们再次运转起来的“诀窍”......

  • 我已经运行了xev，evtest和showkey，除非我执行“解决方法”，否则 FN 键永远无法被检测到，之后在这 3 个程序中可以再次被检测到。

  • 我已经卸载了定制第二个键盘（小键盘）所需的一些守护进程和程序...

  • 我已经将两个用户中运行的守护进程进行了比较service --status-all，systemctl | grep "running"以防万一有某些守护进程修改了一些东西……但在解决方法之前和之后：系统进程是相同的

  • 我检查了我的~/.config文件夹，它与第二个用户的没有什么不同

  • 我也从 升级到Ubuntu 20.x了Ubuntu 22.04.5，但无济于事。

线索：

  • 它可能是我的用户中的某个东西，我无法处理它，
  • 这可能与 X 服务器有关？gnome 似乎在切换用户后没有保留错误的配置
  • 重启后，如果我登录到第二个用户，FN 键可以正常工作，并且在切换到我的第一个用户时继续起作用...所以这只是我的第一个用户的配置缺陷......

我只有 1 个键盘：Logitek G915 TKL，从命令行配置时，我选择列表中唯一最近的？键盘：Logitech G15 extra keys via G15 daemon

Computer: Asus P50N (minibox, not a laptop)

6.8.0-45我目前正在尝试按照类似于此处提到的步骤编译自定义的 Ubuntu Jammy (22.04) HWE 内核版本。我正在对iwlwifi驱动程序应用一些补丁。

以下是我的分步过程：

  1. git clone git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/jammy && cd jammy
  2. git checkout Ubuntu-hwe-6.8-6.8.0-45.45_22.04.1
  3. git switch -c my_branch/6.8.0-45_iwl_patch
  4. 将我的更改应用到drivers/net/wireless/intel/iwlwifi/iwl-nvm-parse.c文件
  5. git add . && git commit -m "My commit message"
  6. cp /boot/config-$(uname -r) .config
  7. sed -i 's/CONFIG_LOCALVERSION=""/CONFIG_LOCALVERSION="-ricciolino"/g' .config
  8. make oldconfig
  9. fakeroot debian/rules clean
  10. fakeroot debian/rules binary-headers binary-generic

一切工作正常，直到第 10 步，我在构建过程中遇到以下错误：

我最近将我的 Lenovo ThinkPad X1 Yoga 4th Gen 换成了 Ubuntu 24。我使用这台电脑工作，自从换了之后就无法使用我们办公室的打印机打印了。我们办公室有两台打印机，我可以打印到我们医疗办公室的 Canon MF 1643i II，但不能打印到 Canon IR AdvanceDX C3835i。我在设置的打印机列表中可以看到这两台打印机，但我只能从 Canon MF 打印。

我已经安装了 cups 并检查它是否正在运行。我已在 localhost:361 上调出 cups gui，并尝试使用我的机器的名称和密码登录，但没有成功。现在当我尝试时，管理页面不会要求我提供凭据，只是说未经授权。我希望得到帮助，重新访问 cups 管理页面，或者找到一种不需要 gui 即可添加打印机的解决方法。在很多方面，我绝对是一个 Linux 新手，所以请知道我需要一些基本的手把手指导。提前谢谢大家！
