我意识到尽管我使用的是蓝牙鼠标,但 Ubuntu 上的蓝牙连接已关闭。几天来,指针一直无法平稳移动,所以我正在寻找可能的原因。我认为鼠标通过其 USB 适配器进行蓝牙通信,但我想知道我是否也应该在 Ubuntu 上启用蓝牙连接。但是打开它并没有帮助解决问题。
Andrew Harlan's questions
我使用 Wayland 很长时间了。现在换成X11了,颜色爆炸了。饱和度太高。怎样才能让它的颜色更自然呢?我在设置中看不到任何颜色配置文件。
我已经为我的智能手表下载了一个备份应用程序,但我无法执行该文件。它说
“在终端中转到包含未压缩文件的文件夹并运行“bash amazebkp.command”,然后按照说明进行操作。”
但是,当我这样做时,我会收到以下消息:
Device not detected! Please re-connect the watch to the computer.
amazebkp.command: line 368: adb: command not found
amazebkp.command: line 369: adb: command not found
需要您的帮助来解决问题。
我在笔记本电脑上使用的 wifi 连接总是随机断开连接,并且一天中会发生很多次。首先,wifi信号开始闪烁,然后询问wifi密码,即使它已经保存了。我需要关闭无线网络,重新打开并重新连接到无线网络以重新连接。
我的网络适配器是:
02:00.0 Network controller: Intel Corporation Wireless 3160 (rev cb)
我不认为这是否是硬件相关问题,因为当我使用 Windows 时没有发生,也不是路由器问题,因为连接到网络的其他设备都可以。
我安装了 Ubuntu 20.04.4 LTS,但没有可用的其他驱动程序。你有什么解决方案可以提供给我吗?

我正在尝试在 Ubuntu 20.04.2 上录制我的电吉他的声音,但由于我的笔记本电脑(Toshiba Satellite Radius 14 L40W-C-102)只有一个音频输入插口,它可以用作耳机插口,所以我无法做到. 虽然我的笔记本电脑的规格页面上说它是“外置耳机(立体声)/麦克风组合插座”。所以,我正在尝试将它用作麦克风(在我的情况下是插座中的线路)来录制声音。当我通过普通吉他电缆和 3.5 毫米适配器将吉他插入此插座时,音量图标变为耳机。如何使用此插座进行录音?
我在笔记本电脑上使用 Ubuntu 20.04.2 LTS 几个月了。我刚刚发生了一次崩溃,这迫使我通过电源按钮关闭电脑。只有鼠标指针在移动,而且它也结结巴巴。那时 Firefox 上有 4 个打开的标签页。我想知道这次崩溃的原因。可能吗?
我怀疑它是由硬盘驱动器故障引起的。是否有任何日志文件可以检查?

我从不在笔记本电脑上使用蓝牙并通过右上角的菜单将其禁用,但每次重新启动后它都会再次打开。我的笔记本电脑上也没有物理按钮来打开和关闭它。几周前并没有发生这种情况,但我认为最新的更新导致了这种情况的发生。
我怎样才能完全禁用它?
我试图安装一个名为 i-nex(cpu 临时监控工具)的应用程序,但我不能,因为找不到包。但是,它在系统上留下了一些评论。现在,当我尝试更新 apt 时,出现以下错误。我该如何摆脱这个?

我对 Ubuntu 20.04.2 有一个奇怪的问题。登录一段时间后,我无法通过扩展坞在应用程序之间切换,因为单击图标没有任何效果。由于同样的原因,我也无法访问顶栏上的任何功能。桌面图标也不响应点击。我只能通过 alt+tab 切换应用程序。我必须注销并重新登录才能解决此问题。
这可能是因为我的硬盘有问题。我将很快用 SSD 替换它,但我想知道硬盘故障如何导致这样的问题。
注意:我不使用任何 gnome 扩展。
我刚刚在加载 Ubuntu 时在笔记本电脑屏幕上看到了以下错误消息,但我能够毫无问题地登录。你认为这里可能出了什么问题?
