使用两个独立指针在双屏设置中将鼠标绑定到混凝土监视器

场景是，将我的 Wacom Bamboo 绑定到第二台显示器，将鼠标绑定到第一台显示器。Wacom Bamboo 的装订与数位板的设置完美搭配。但是如何将鼠标绑定到另一台显示器？

我目前的步骤：

将 Wacom Bamboo 绑定到我的第二台显示器

配置两个独立的指针

使用插入的 Wacom Bamboo 和我的鼠标，xinput --list显示

如此屏幕截图所示：

我正在寻找一种简单的方法在终端内使用诸如以下的命令来执行此操作

sudo apt-add-update enable updates
sudo apt-add-update enable proposed
sudo apt-add-update enable backports
sudo apt-add-update enable security

sudo apt-add-update disable updates

通过 udev 忽略两个 USB 记忆棒的一个分区

我有一个带有两个分区的 USB 记忆棒。插入棒后，我使用以下命令查找设备。

dmesg

示例输出

[11195.236020] usb 2-2: new high-speed USB device number 9 using ehci-pci
[11195.375432] usb 2-2: New USB device found, idVendor=058f, idProduct=6387

[11196.390454]  sdc: sdc1 sdc2
[11196.394696] sd 10:0:0:0: [sdc] Attached SCSI removable disk

因此，我的设备是/sdc，我的分区/dev/sdc1和/dev/sdc2

我使用这两个命令来获取他们的 UUID

udevadm info /dev/sdc1 | grep ID_FS_UUID=

示例输出

E: ID_FS_UUID=dbf323e9-8d63-444c-9c11-76b9b9a0fed4

和

udevadm info /dev/sdc2 | grep ID_FS_UUID=

示例输出

E: ID_FS_UUID=0eeb7004-8955-4358-a205-07d7376adb8c

dbf323e9-8d63-444c-9c11-76b9b9a0fed4因此我的UUID 是0eeb7004-8955-4358-a205-07d7376adb8c

或每个分区

/dev/sdc1>> dbf323e9-8d63-444c-9c11-76b9b9a0fed4
/dev/sdc2 >> 0eeb7004-8955-4358-a205-07d7376adb8c

现在我创建了一个文件/etc/udev/rules.d/100-myusb.rules

sudo nano /etc/udev/rules.d/100-myusb.rules

并添加了以下规则

KERNEL=="sd??", ENV{ID_FS_UUID}=="0eeb7004-8955-4358-a205-07d7376adb8c", ENV{UDISKS_IGNORE}="1"

并重新启动udev

sudo service udev restart

但是再次插入棒后，两个分区都显示为FilesakaNautilus

我做错了什么？

编辑所以 2015 年 9 月 6 日 21:07:50 CEST

规则

KERNEL=="sd??", ENV{ID_FS_UUID}=="0eeb7004-8955-4358-a205-07d7376adb8c", RUN+="/bin/mkdir /tmp/folder1"

创建文件夹/tmp/folder1

对于@Sneetsher

KERNEL=="sd??", ENV{ID_FS_UUID}=="0eeb7004-8955-4358-a205-07d7376adb8c", RUN+="/usr/bin/env > /tmp/udev-partition-env.log"

有效，但输出文件是env_root.output？o_O

编辑 Mo 7. Sep 20:31:06 CEST 2015

经过测试但不起作用

KERNEL=="sd??", ENV{ID_FS_UUID}=="0eeb7004-8955-4358-a205-07d7376adb8c", ENV{UDISKS_AUTO}="0", ENV{UDISKS_SYSTEM}="0"

为什么我可以删除 root 用户拥有的文件？

5

正如标题所说：为什么我可以以 root 用户身份删除文件？

这是一个例子：

% sudo touch ~/test

% ls -la ~/test    
-rw-r--r-- 1 root root 0 Jun 18 20:31 /home/aboettger/test

% rm ~/test
rm: remove write-protected regular empty file ‘/home/aboettger/test’? Y

% ls -la ~/test
ls: cannot access /home/aboettger/test: No such file or directory

WLAN 问题：(wlan0/wireless)：关联时间过长，激活失败

4

我有一台笔记本电脑

英特尔公司无线 3160（修订版 83）；固件版本 25.17.12.0

我看到 WLAN，我可以输入我的密码。尽管重复输入密码并目视检查密码，但仍未建立连接。

路由器上没有 MAC 过滤，并且允许所有（新）设备。

在使用 Ubuntu 安装的固件测试网络之前，我已经从Linux Wireless安装了固件。

我该如何解决这个问题？

我用我的智能手机创建了一个热点。同样的问题。

IPv6 禁用，同样的问题

$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6

$ ip a | grep inet6
*no output*
