Welcome to the Linux forum Snorty!

Unfortunately problems with suspend and hibernation are very common with Linux. But fortunately everything worked fine before in your case. Therefore I have high hopes that this problem can be solved.

Does your screen come back after a reboot?

Do you mean "suspend" or "hibernation" with the word "sleep"?

What kind of version of LinuxMint are you using right now?

Have you recently gotten a new kernel version? This often affects issues with suspend or hibernation. Changing back to an earlier kernel version that caused no problems is often the only and best working solution.

Select menu, then type "system information" , then you will find what type of linux system you are using.

Yes, extensive Details are always needed here, to get useful help. Is your ASUS the "ROG" bad boy with the nVidia GTX 10 GPU? "All" nVidia GPU devices have had proprietary Drivers for many years. The 'soft' GPU drivers in the GNU/Linux world can never get "all" functions correct. [ See Webster's definition for Proprietary ] More importantly for you, is that your GPU will generate HEAT when stressed, which your laptop 'mini' Cooling System may NOT be able to move out ... causing Overheating/Dead PC. Be very careful to monitor your GPU and CPU and HDD temperatures, at all times!... BEFORE making changes.

Does your screen come back after a reboot?
Yes

Do you mean "suspend" or "hibernation" with the word "sleep"?
Yes. The issue happens after Suspend, Hibernation and if the Screen Turns Off after time.

What kind of version of LinuxMint are you using right now?
Currently, it's Linux Mint 18.3 Cinnamon

Have you recently gotten a new kernel version?
Yes, so I did try rolling back, but it did not resolve the issue. Since then, I have had a few kernal updates occur.

Select menu, then type "system information" , then you will find what type of linux system you are using.
Linux Mint 18.3 Cinnamon 64-bit
Kernal 4.15.0-38-generic

Snorty, What was the Linux OS with which everything worked fine before?

Did you install new Nvidea drivers just before everything started going wrong with your screen?
Have you tried disabling the Nvidea drivers and have you tried installing the LinuxMInt Noveau drivers instead?

Select "Menu" and type "Driver ". Click on the Driver Management icon and check what sort of driver you are currently using. You can select the LinuxMint nouveau driver in that very same field.

Snorty, another step you can take to find out what is going in is the following:
select "Menu" and type "Logfiles". Open the logfiles and look at the submenu "Important". It will list the most important error messages. Double click on every error message to see what level of importance the error messages are.

Post back the results of the error messages on the forum so more forum users can help you find the cause of your problem.
