ubuntu 22.04 flameshot 截图异常的问题

方法找了好久，终于找到一个有用的

Firstly do not install flameshot from snapstore, install it using apt.

• Go to /etc/gdm3/custom.conf
• Remove the comment on #WaylandEnable=false

Your custom.conf file should be like this:

# GDM configuration storage
#
# See /usr/share/gdm/gdm.schemas for a list of available options.

[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false

# Enabling automatic login
#  AutomaticLoginEnable = true
#  AutomaticLogin = user1

# Enabling timed login
#  TimedLoginEnable = true
#  TimedLogin = user1
#  TimedLoginDelay = 10

[security]

[xdmcp]

[chooser]

[debug]
# Uncomment the line below to turn on debugging
# More verbose logs
# Additionally lets the X server dump core if it crashes
#Enable=true

Save custom.conf file and restart your machine
