Hi Thran,

Sorry to hear you're having issues with your system being unresponsive while using Linux/Youtube.

If you haven't already, try following these steps in the Knowledge Based article to see if it resolves the issue : Firefox crashes - Troubleshoot, prevent and get help fixing crashes {link}

It is recommended you try and check to see if the crash happens in Safe Mode before moving forward. Diagnose Firefox issues using Troubleshoot Mode {link}

Have you tried disabling hardware acceleration? Hardware acceleration and WindowBlinds causes Firefox to crash {link}

Get the Report ID of your latest crash report by opening about:crashes in the address bar and copy and paste the Report ID for the latest crash beginning with bp-

WMagicModel,

I tried to restart Firefox into safe mode. Unfortunately, it also crashed whilst trying to perform this. The crash report of that incident was: bp-61e8eb09-4b4b-4817-bc7b-d160a0190919. I also have some more details from the xsession-errors which I shall append at the end of this reply.

The latest crash report before this has ID: bp-c3441f06-f87f-4f0c-a7bb-e43620190917. It is possibly corresponding with the hang mentioned first, though when these happen the system itself hangs (mouse and keyboard unresponsive, any audio will become "stuck" on the last second ad infinitum) and I must do a hard reset. I presume that the Firefox crash reporter would not have had the chance to gather anything on the hang.

Edit: Running Firefox with hardware acceleration disabled still causes this super-hang.

Hi Thran,

Was this something that has always been occurring since you've had it, or an update/upgrade to Firefox?

I noticed allot of crashes in version 69.0 with that report. You could try installing Firefox Nightly which gives you the opportunity to test out the latest features while being a possible remedy to your problem.

WMagicModel,

As far as I remember this hang has been happening. I have been using this laptop since early July. I think more than one major release of FF made its way downstream to Ubuntu in that time.

I have installed Firefox Nightly (v71) by way of a PPA repository. Thus far, it hasn't crashed in the same manner. I'll continue trying it for a week and get back to you if this happens again.

As far as new features go, I can only give hearty approval to the new anti-tracking tools.

Best wishes, Thran

Dear WMagicmodel and other users,

I fixed this issue by going into the ThinkPad BIOS and disabling some of the hardware that I wasn't using. This included the security chip and fingerprint reader. And lo, I could open up YouTube and stream five videos at once in highest of definitions using Firefox. This proved to me that the issue was fixed.

I reckon that it was the security chip. Overall, my system seems much stabler since disabling it. Now I'm a happy man!

So in short, if anyone else is having this same issue using Linux on a ThinkPad T450, try disabling the security chip. It may well be that it is meant for only Windows and its presence conflicts with a Linux system.

Happy computing, Thran
