解决y7000笔记本ubuntu18.04下 休眠挂起后唤醒花屏

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=
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=
GRUB_DISTRIBUTOR=`lsb_release -i -s > /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
