定位问题，切换到核显后发现一点问题也没有，基本确定是显卡驱动的问题
但是由于配置环境比较复杂，不想重新装N卡驱动，所以另寻方法
sudo gedit /etc/default/grub
修改前
# If you change this file, run \'update-grub\' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n \'Simple configuration\' GRUB_DEFAULT=0 GRUB_TIMEOUT_STYLE=hidden GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo\' #GRUB_GFXMODE=640x480 # Uncomment if you don\'t want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"
把里面的 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
改成 #GRUB_CMDLINE_LINUX_DEFAULT="text"
实测没有效果
为了保证工作安全，忽略笔记本合盖的休眠
打开terminal：
sudo vim /etc/systemd/logind.conf
然后将其中的：
#HandleLidSwitch=suspend
改成：
HandleLidSwitch=ignore
