Whenever I turn on my PC, it goes to a pure purple screen then it goes black

Question

This happens with restarting too. When I restart it turns off just fine, but then when it turns back on, it goes to a purple screen and then black.

However it does turn on after I hold the power button until it turns off, and then turn it back on again. This isn't a crucial fix, just really inconvenient. Thanks for your help.

Answer 1

Though it may not be a complete solution, when the screen is black you may try to access the terminal via Ctrl+Alt+F1/.../F6 and try to sudo service lightdm restart.
