Public bug reported:
Hello, ive reported this some few times before, I even apointed mister
Shuttelworth to the bug, but they said I had other bug, I will include
information reported by others, because I dont know how to shh into the
problem.
By fixture:
I installed ssh-server to get to the bottom of this. When the computer
froze, I ssh'ed into it. Surprise! It worked.
It turns out that this is not a kernel freeze. Mouse moves but Caps lock
does not respond. In the ssh session, I went into top and htop. Nothing
suspicious at all, in fact, there's no cpu usage at all! I do even know
what to go on.
Then I theorized that this is a graphics hardware problem. I went to
test this out by restarting GDM. This little bit of kernel log is what
you get:
[ 723.628131] [drm:i915_gem_idle] *ERROR* hardware wedged
[ 723.640543] [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count
for disabled pipe 0
[ 791.378469] [drm:i915_gem_entervt_ioctl] *ERROR* Reenabling wedged hardware,
good luck

I also attached the bigger kernel log to the message.
