[Desktop-packages] [Bug 1266784] Re: i915_set_reset_status *ERROR* render ring hung inside bo

2014-02-21 Thread Simon SimonG
I'm having very similar issues and I noticed that the same symptoms
appear when I change my screen orientation, log out and log back in.
For some reason, If I keep the rotation normal and use xrandr to
manually rotate the screen, I don't get these problems.

Christopher, are you changing the screen rotation by any chance?

Bug description:
  This is occuring when I change users, and when I log in from the login GUI, 
but not 100% of the time (!). 
  It just started yesterday.

  Boot brings up the graphical login screen normally. I log in with the 
primary/only user, and the screen goes very dark and I get just a mouse pointer 
which appears and moves if I use the mouse (trackpad or etc).
  I don't seem to be able to get windows to work, but if I could I couldn't see 
them, since the screen stays black except for that pointer.

  If I type Ctrl-Alt-F1, it takes a few seconds rather than less than 1
  to get to a TTY.  There, there is a steady but slow stream of errors
  coming up that look like this:

  *ERROR* render ring hung inside bo (0) at (0)
  drm:i915_hangcheck_elapsed
  i915_set_reset_status *ERROR* render ring hung inside bo

  
  I can however, log in fine in TTY and access my files. It looks like nothing 
much is running (top), and I don't see the normal X processes.

  This is making my computer unusable.  I'm running on the latest 13.10 on a 
Lenovo thinkpad X230tablet.
  I don't think I made any changes. There was one update that occurred shortly 
before this started yesterday, but it doesn't have anything suspicious-looking 
in it.  It was:

Please note that with these bugs, the /sys/class/drm/card0/error file is
vital for debugging the issue.

Re: [Desktop-packages] [Bug 1266784] Re: i915_set_reset_status *ERROR* render ring hung inside bo

2014-02-21 Thread Christopher Barrington-Leigh
Whoo. By what means, if not xrandr?  I'm certainly changing screen rotation
sometimes, though not by choice. One of the many things that's buggy or
become buggy on this wretched machine (ie combo of hardware and software)
is that when I undock my laptop from its dockingstation (and possibly in
other circumstances too?), the screen sometimes rotates the way it might if
I were converting to tablet mode (It's an X230 tablet).
 However, I don't think I've noticed anything like a 1-to-1 relationship
between that problem (fixed simply by pushing a rotate-screen hardware
button next to the display) and the can't-login problem. I don't know how
to initiate the problem, in fact.

Is yours fully reproducible?
