要退出QEMU，可以同时按住ctrl+a，松开后再输入'x'
```
#### 5.6 改进驱动
如果在驱动程序里设置属性位：
```shell
__set_bit(INPUT_PROP_DIRECT, g_input_dev->propbit);
```
那么tslib可以自动扫描到触摸屏设备，
使用tslib时就不需要设置这些环境变量：
```shell
export TSLIB_TSDEVICE=/dev/input/event3
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_PLUGINDIR=/lib/ts
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
