还有个sudo dmesg -w应该也可以用（）但是我没试过（）应该是实时的，适合复现
日志里面nvt_ts_suspend之后nvt_ts_resume，但是失败了nvt_check_fw_reset_state 537: error, retry=11, buf[1]=0x00
尝试解决
如果在模块当中，应该用
lsmod | grep -iE(E是正则表达式~) 'nvt|novatek|touch|andAnyOtherTings'
然后像后面一样，写个禁用脚本
# 查找SPI 总线上的 Novatek设备(显驱设备)
ls /sys/bus/spi/devices/
# 如果是spi0.0
ls -l /sys/bus/spi/devices/spi0.0/driver
#然后得到这个名字
sudo nano /usr/lib/systemd/system-sleep/99-nabu-touch-fix.sh
#写这个脚本，脚本内容大概类似于
#!/bin/bash
case $1 inpre)# 休眠前：强行卸载触摸屏驱动modprobe -r nvt_ts_spi;;post)# 唤醒后：重新加载触摸屏驱动modprobe nvt_ts_spi;;
esac
然后
sudo chmod +x /user/lib/systemd/system-sleep/fix-touch.sh
#或者写用户自定义区/etc/lib/systemd.....
另一种情况
如果内核没有集成触摸，即触摸模组不作为模块加载，而是built-in的（类似于我手上这种） （我猜可以这么说？管他呢 把问题解决就行）
一样找到spi几几
然后船舰脚本
sudo nano /usr/lib/systemd/system-sleep/99-nabu-touch-fix.sh
#!/bin/bash# 设备 ID
TOUCH_DEV="spi0.0"DRIVER_PATH="/sys/bus/spi/drivers/nvt_ts_spi"case $1 inpre)# 在进入休眠前解绑驱动 #不作为模块加载，编译在内核，利用解绑机制if [ -e "$DRIVER_PATH/$TOUCH_DEV" ]; thenecho "$TOUCH_DEV" > "$DRIVER_PATH/unbind"echo "Touch screen unbound before suspend" >> /tmp/touch_fix.log #可要可不要fi;;post)# 在唤醒后重新绑定驱动if [ ! -e "$DRIVER_PATH/$TOUCH_DEV" ]; thenecho "$TOUCH_DEV" > "$DRIVER_PATH/bind"echo "Touch screen re-bound after resume" >> /tmp/touch_fix.log #随便你吧fi;;
esac
然后不要忘了
sudo chmod +x /usr/lib/systemd/system-sleep/99-nabu-touch-fix.sh
然后休眠试试看
