我为 Firefox 创建了一个 .Desktop 文件（我从他们的网站下载了每晚版本）。这是文件。

[Desktop Entry]
Version=1.0
Name=Nightly
Comment=This is the nightly entry ie firefox entry
Exec=/opt/firefox/./firefox
Icon=/opt/firefox/icons/logo.png
Terminal=false
Type=Application
Categories=Accessories;
GenericName[en_IN]=this should start firefox

我放置了这个文件，.local/share/applicaitons以便从扩展坞中进行搜索。但是，每当我启动应用程序并右键单击 Dock 上出现的图标时，它不会让我选择将应用程序锁定到收藏夹，只允许我退出或显示所有窗口。我正在使用GDM3.

unity gdm unity-dash

我最近在笔记本电脑上安装了 Nvidia 显卡。然而，即使在安装后机器仍然使用英特尔图形芯片。我尝试运行prime-select nvidia，nvidia profile is already set但每当我尝试检查我正在使用的显卡时，输出是，

lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA

输出仍然

00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 520 [8086:1916] (rev 07) (prog-if 00 [VGA controller])

我也试过

optirun glxinfo|egrep "OpenGL vendor|OpenGL renderer"

输出

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: llvmpipe (LLVM 5.0, 256 bits)

但仍然没有效果。我尝试nvidia-setting通过 GUI 配置主要配置文件，但未prime profile显示该选项卡。注意：我通过 deb 文件安装了 nvidia-prime，apt install nvidia-prime似乎没有用。

更新
输出sudo lspci -nnk | grep -i vga -A3&&sudo lshw -c display

我最近（今天）在我的笔记本电脑上安装了 Nvidia 图形驱动程序，我按照教程中的说明使用nvidia-xconfig. 我正在使用笔记本电脑并已插入外接显示器，外接显示器的分辨率很好，但笔记本电脑的主屏幕已达到 4:3 分辨率。我不知道xorg.conf文件中有什么，我从来没有见过这样的东西，谁能帮我把屏幕分辨率改回 16:9、1366x768。

这是 xorg.conf 文件。

我通过网络设置在我的机器上设置了一个系统范围的代理，代理是 localhost:9191（我使用的是 Burpsuite）。我现在已经禁用了上述代理。当我试图通过 git clone "url" 克隆一个 git 存储库时，它给出了一个错误unable to connect to 127.0.0.1 port 9191。但是我禁用了代理！谁能帮忙？我重新启动了，network-manager但似乎仍然没有工作。我也尝试更改代理的端口，即使将端口更改为 80，我得到的错误仍然是can't connect to localhost port 9191
