You're experiencing several issues with your new Ubuntu setup on the Thinkpad E15 Gen 2. It seems the display settings aren't responding as expected, and the lock functionality isn't working properly. This could be due to a faulty installation or driver problems. You might want to check the display configuration files, ensure the graphics drivers are up to date, and verify that the power button and lid lock features are correctly enabled in the system settings. If the problem persists, consider reinstalling the display drivers or consulting the manufacturer's support for further assistance.
