The past two weeks, 3 times my computer has completely frozen (nothing responds and the image is frozen on screen) and the caps lock key’s light will be blinking. I think it’s a kernel panic but I’m not sure what’s causing it.
How do i diagnose what’s causing it? What do I look at? Commands? Log files?
openSUSE 42.1
Linux 4.7.2-1
KDE
Lenovo X1 Carbon 4th gen
Video and driver ???
Command:
/sbin/lspci -nnk | grep VGA -A2
Output:

Sorry don’t know about Intel Graphics Check the posts for possible problems with the newer modes. Seems there is a fix by modifying the xorg files
Do you know where I would look for those posts? I’m not even sure what you mean by modes. thanks 
See
Don’t know if this is the problem but Intel GPU seem to require this at least on some hardware
Thanks! Do you mean this answer? (There’s a few diff answers)
Think that is the one that is most recommended
If that causes an issue, how can I start up and remove it?
What do you mean??? Just edit or add the indicated text files as root?? Boot to a terminal if you need or edit file from a live DVD/USB
