Sorry for the bump guys, but I seem to be having a problem and there is no other place to ask it than in a group of Linux users. I have been researching the last few weeks how to fix this problem where whenever I close my laptop screen, it crashes Linux Mint. I have tried solutions found on many websites (including the once regarding ubuntu/LM) but none of them work. When in the middle of accessing files, I assume that it forcing it to shut down can/will result in a file system failure. After reinstalling LM18.1, this issue seemingly went away, until yesterday. I force shut it down about to reboot and look up how to fix it again, but it won't boot! I tried Upstart mode. Nope, CPU#Whatever soft-lockup! Frozen for 22 seconds. Only booting through recovery mode will it boot. I assume it has to do with my graphics drivers/hardware because it will boot in recovery mode where everything is processed in the CPU, not the GPU/video processor. Any help that you guys can provide would be appreciated, as this exact same problem caused me to reinstall LM after it stopped booting
