部分电脑安装升级 ubuntu 12.04 后无法挂起问题的解决(挂起无法唤醒同样有效)

我的Ubuntu12.04是安装的windows桌面安装版(使用wubi安装),原来使用状况良好,前两天安装了更新后,发现系统挂起后不能唤醒--出现的状况有:屏幕暗黑但是能移动鼠标,打不开原桌面即使有时能打开桌面但是什么功能按键也没有,需要进入终端(Ctrl+Alt+F1)重启系统!

google了很久终于找到解决方法，根据[http://ubuntuforums.org/showthread.php?p=11926504][http_ubuntuforums.org_showthread.php_p_11926504]方法解决了。  
方法：  
一、打开终端在/etc/pm/sleep.d/建立20\_custom-ehci\_hcd文件  
sudo gedit /etc/pm/sleep.d/20\_custom-ehci\_hcd  
二、复制下面代码到文件里保存并退出

    VERSION=1.1
    DEV_LIST=/tmp/usb-dev-list
    DRIVERS_DIR=/sys/bus/pci/drivers
    DRIVERS="ehci xhci" # ehci_hcd, xhci_hcd
    HEX="[[:xdigit:]]"
    MAX_BIND_ATTEMPTS=2
    BIND_WAIT=0.1
    unbindDev() {
    echo -n > $DEV_LIST 2>/dev/null
    for driver in $DRIVERS; do
    DDIR=$DRIVERS_DIR/${driver}_hcd
    for dev in `ls $DDIR 2>/dev/null | egrep "^$HEX+:$HEX+:$HEX"`; do
    echo -n "$dev" > $DDIR/unbind
    echo "$driver $dev" >> $DEV_LIST
    done
    #for bus in $EHCI_BUSES; do
    echo -n $bus > /sys/bus/pci/drivers/ehci_hcd/unbind
    # done
    done
    }
    bindDev() {
    if [ -s $DEV_LIST ]; then
    while read driver dev; do
    DDIR=$DRIVERS_DIR/${driver}_hcd
    #for bus in $EHCI_BUSES; do
    echo -n $bus > /sys/bus/pci/drivers/ehci_hcd/bind
    #done
    while [ $((MAX_BIND_ATTEMPTS)) -gt 0 ]; do
    echo -n "$dev" > $DDIR/bind
    if [ ! -L "$DDIR/$dev" ]; then
    sleep $BIND_WAIT
    else
    break
    fi
    MAX_BIND_ATTEMPTS=$((MAX_BIND_ATTEMPTS-1))
    done
    done < $DEV_LIST
    fi
    rm $DEV_LIST 2>/dev/null
    chvt 1
    chvt 7
    }
    EHCI_BUSES="0000:00:1a.0 0000:00:1d.0"
    case "$1" in
    hibernate|suspend)
    unbindDev;;
    resume|thaw)
    bindDev;;
    esac

三、改变20\_custom-ehci\_hcd文件权限  
sudo chmod 755 /etc/pm/sleep.d/20\_custom-ehci\_hcd  
四、重启  
我电脑就是这样弄好的。
