Closing lid causes system hang

[ritwik]

I have been having this problem for a past few weeks. I have been using this system for almost 1 year. I use with the power setting to suspend my system when I close the lid. In the past few weeks sometimes when I close the lid, the system doesn't gets suspended. Instead, it gets stuck. When i reopen the lid screen will be back and nothing can bring the system back. I have to restart the system by pressing the power key. No key is working during this state. I tried pressing num lock and no response. It happened rarely before. But for past few days, my system has been getting stuck like this more. Before this, I used to have system crash suddenly and lose all data without any reasons. I am fairly new to ubuntu I don't know how to diagnose these things. Please help me.
Thank you

Is this problem still present in current Ubuntu releases?

Recently I moved to ubuntu 18.04. Still the issue is happening
occasionally. Sometimes the whole system restarts.

Another issue with 18.05 noticed. In auto brightness the screen is turning
off sometimes when I am using it at minimal brightness. I think this should
be easily fixable.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Sure. Will check it and update. Will probably takes some time to update
since issue is not reproduced everytime. I will use it for 1 month max and
if no issue report same fine?
