Public bug reported:
I own an HP LP3065 monitor (http://www.amazon.com/dp/B000KB6E3G/) with a
BizLink displayport adapter (http://www.amazon.com/dp/B003XYBA72/). The command
sudo get-edid -b 6 | parse-edid correctly identifies the available
resolutions of the screen as 2560x1600 and 1280x800.
I guess it is way to late for me to figure that out now. However, you
might try to run your computer from a USB pen, installing Ubuntu 14.04
with unetbootin and then see what behavior you get. That is what I did
and made me realize that the problem likely relied in some settings.
Maybe try
For some weird reasons, by deleting all configuration files in my home
directory, the behavior reverted to what it was with Ubuntu 13.10. I
cannot reproduce the crash anymore. I still need to add the correct
resolution with xrandr as it is not detected correctly. Somehow there is
a lurking bug in
It is a Dell BIZLINK DisplayPort to DVI Dual Link Adapter (see here:

I have some new information. Apparently, I tried a different external
monitor with the displayport and the same 2560x1600 resolution and the
laptop worked just fine. I can run xrandr or unity-control-center while
the monitor is connected and there are no issues.
The monitor that does not work
I wonder if this is the same as bug

pureblood, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com

I still have not experienced a single GPU hang since I added the options
i915.i915_enable_rc6=0 i915.i915_enable_fbc=0 to the grub command line. This

Provided that it is likely that people in this forum are affected by different
bugs, I will share my own experience. I have been using in the last weeks

(i915.i915_enable_rc6=0) and #280 (i915.i915_enable_fbc=0), my Dell
Vostro V131 with Sandy Bridge and HD 3000 has not hard crashed (no mouse
movement, no SysRq, no ssh) for about a week using kernel 3.4.1

Actually in the log I posted it says [drm:intel_enable_rc6],
Sandybridge: deep RC6 disabled, do you think I have it enabled instead?
What did you see in the log file?

Since the bug many people are experiencing is related to hard freezes
where you *cannot* move the mouse anymore or ssh the machine, maybe a
new bug should be opened with these directions in the title, and then
people should be directed from this thread to that thread instead. I

I have to agree with yorgasor #20. There are two different bugs here. I
happened to be affected by both. I could reproduce the google-earth bug
by running google-earth and zooming into something. The X server would
lock, but I could still move the mouse. Using the sudo intel_reg_write

I confirm that I have had the same problem since I upgraded to Ubuntu
Precise. The freezes I experience are completely random, sudden, and
there is nothing I can do. I tried upgrading to 3.4.0 and I still
experienced freezes. I tried downgrading to 3.0.0 and I still experience
freezes. I have just
