我的Ubuntu 12.04系统上一直都不能正常连接我的Galaxy Nexus 3手机，今天下定决心要解决这个问题。Google了一下，找到了解决的办法。
首先要更新MTP的库，据说Ubuntu 13.10的MTP库已经很好用了，网上有可以直接提供好的源可以直接下载。
sudo add-apt-repository ppa:langdalepl/gvfs-mtp
Enter your user password and than you’ll be shown following text:
You are about to add the following PPA to your system:These builds of gvfs have my native mtp backend backported from gvfs master. Use this to easily access MTP based devices with Nautilus.More info: https://launchpad.net/~langdalepl/+archive/gvfs-mtpPress [ENTER] to continue or ctrl-c to cancel adding it
Hit the Enter Key. After this is done you need to type following command, which updates the package list:
sudo apt-get update
After this was successful you need to upgrade the installed packages with:
sudo apt-get upgrade
然后就是发现这样还是不行，会弹出USB错误的提示，有人提示说要加Android在ubuntu中的连接规则。
3. Configure 51-android.rules:sudo gedit /etc/udev/rules.d/51-android.rulespaste the following at the end of the file (if the file does not exist then just paste):#LG – Nexus 4SUBSYSTEM==”usb”, ATTR{idVendor}==”1004″, MODE=”0666″#Samsung – Nexus 7 & 10SUBSYSTEM==”usb”, SYSFS{idVendor}==”18d1″, MODE=”0666″
Save and exit.4. Make the file executable:sudo chmod +x /etc/udev/rules.d/51-android.rules5. Restart udevsudo service udev restart
，人生没有彩排，每天都是现场直播。
