i read this under known issues:
Now i have removed xserver-xorg-video-intel driver and now output inxi says this:Cinnamon freezes when changing resolution (Intel GPU)
If your Intel GPU is recent enough (2007 or newer) it is recommended to remove the legacy Intel driver "xserver-xorg-video-intel" and to use the built-in modesetting driver instead:
apt remove xserver-xorg-video-intel
sudo reboot
Not only will the modesetting fix the freeze issue when changing resolutions, it should also work better with Cinnamon and produce better performance.
The legacy driver is no longer maintained and only useful for the old i800x and i900x family of chipsets.
If you are using one of these old chipsets or if you do not want to use the modesetting driver, an alternative is to continue to use the "xserver-xorg-video-intel" driver, but to disable VSync:
echo CLUTTER_VBLANK=none >> ~/.profile
Log out for this change to take effect, and please be aware that disabling Vsync might result in video screen tearing.
