I suppose that's one possible answer, but I have the same problem on Ceres.  If I try to run two different videos at the same type my system freezes solid.  The only way out is to press and hold down the power off button.  That's not a good option.

Are you streaming the videos on wifi? I had wifi related lockups on MX and Devuan, and fixed them by turning off USB Autosuspend in tlpui. Clearly tlp was not playing nice with my wifi card. Just figured I would throw that out there.

If it's not wifi related or some setting in tlp, feel free to share how you are watching the two videos when the lockup happens. I can try to recreate it on my antiX Sid install, maybe we'll find it's some wayward Sid package that's causing the lockups.

Next step: see if AQemu works, despite the IOMMU BIOS setting being disabled by default. Goal: run Win7 as VM.

Come to think of it, it could be related to power management and/or screensaver stuff instead. I have the screensaver turned off and the power management switched off to the maximum intent, but after a period of no user input (mouse, kb), the screen still blanks itself (which is probably inside the monitor). I need to look that up and see if I can counter this behaviour (IIRC there was a kernel option to disable it, not sure)

(PS: for those who want to look it up, the mainboard is a Gigabyte F2A88XM-D3H with BIOS version F8, CPU is an AMD APU: PRO A10-8750B, no separate discrete GPU)

ALWAYS_SET_PATH yes

in /etc/default/su

But you still have to use su -, you just don't get sent to /root.
Right?

Best,

After making the edit:
Use su -if you want to cd to /root.
Use su if you want to stay in the current directory or if you want to run a graphical app as root on the user's desktop. (e.g. I frequently start gparted from terminal because I'm already in a terminal and it's easier than going up to the menu.)

@Dutch_Master: check to see if your cpu or motherboard is known to freeze with linux. I have one box that needs an extra boot option to prevent lockups.

Well, after one too many freeze up I ditched Beowulf, tried to get Funtoo to work (but a core package for Mate failed to configure repeatedly and consequently build) then late last night I took my ASCII USB stick and booted from it. Installed ASCII, but sadly, the random freezes are still there. It might be related to Firefox, may need to look into that.

So, not a happy chappy here, to say the least >:-{  I may try Mint, but that means [shudder] systemd :puke:

have you tried a decent memtest?

I had intended to creat the file /etc/default/su with the content ALWAYS_SET_PATH yes, but all I did was paste in the file address instead of the command. :'-(

Sorry for the bumb steer.

I don't want to change to /root.

Ahh ...
And I thought I was the only one.  8^D

I'm trying hard to get use to su - and how it works.
Sometimes I fear that not being where I want to be (and in /root instead) will make/allow me to do something stupid.

ahh, no. I thought I was the only one! Funny, not funny.

I have nothing to add, except the ufw program complains when trying to start that user ID is 1000 when 0 is expected. Which I think may be a similar problem to the above, so I'm following this thread. Thank you.

So far, Beowulf impresses me badly for all the wrong reasons
