This is probably due to the open source 'nouveau' driver the system is using. Please open the 'Additional Drivers' app and use it to install the Nvidia driver it recommends.
If the problem continues to happen after that then next time the freeze occurs: 1. Wait for 10 seconds. 2. Reboot. 3. Run these commands: journalctl -b-1 > prevboot.txt lspci -kv > newlspci.txt and attach the resulting text files here. ** Tags added: nouveau ** Summary changed: - Xorg freeze after closing lid and Suspend + Screen freeze after closing lid and suspend ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1900910 Title: Screen freeze after closing lid and suspend Status in Ubuntu: Incomplete Bug description: Starting a few days ago, after I close my laptop lid and Ubuntu suspends, I get only a black screen (and the power light is on) when I open the laptop lid. I tried various 3-finger salutes, and nothing changes. There is no cursor. I cannot get to the console screens. The only thing that works is holding the power button until the laptop shuts off.
