Actually, I think I know what the problem is. The 820M is one of those
card with a boost feature and on Windows the driver will boost until the
GPU temperature reaches 70C, then the driver will start downclocking the
GPU. On Linux this feature seems to be missing, the driver never

I would think it a good idea if setting the pstate to performance

Yes, you have a point there about injecting idle time to the CPU to cool down
the GPU. The thing is that modern GPU's (and CPU's) already have thermal
protection so I don't need intel_powerclamp to protect anything. Now, if I was
interested in keeping the power usage down then powerclamp would
I should probably add that suspend/resume worked just fine in 13.10 with

Hi Christopher,
I updated the BIOS to F.18 but it doesn't change anything. Suspend/resume still
behaves as stated above. I also tried with the Nouveau driver but the result is
similar; on resume you get the graphical login screen (at least) but it does
not accept any input (keyboard or mouse)

Hi William,
How is your GPU temperature when this happens? Btw, as a more permanent
temporary fix than rmmod you can blacklist it by creating the file
/etc/modprobe.d/blacklist-intel_powerclamp.conf and adding the line blacklist
intel_powerclamp to it.
As for my problem, I think it's a bit
I have noticed the same thing. If I start playing a game in wine, say
ETS2, on my laptop (Intel HD 4000+Nvidia 820M) it runs fine for maybe a
minute and after that the FPS drops like a rock. The problem, if you
can call it that, is that the GPU temperature goes above 85C and thus
powerclamp kicks
Addition: the CPU temperature never goes above 80C when this happens and
I don't think the GPU temperature is a problem, I think the driver or
GPU itself will slow down if it gets too hot (but I could be wrong).

It seems this is still not fixed. I have rsyslog 5.8.11-2ubuntu2.2
running on 13.04 and the full hostname (using either $PreserveFQDN or
$LocalHostName) is only used for messages from rsyslog itself. Messages
from sshd, sudo, pam etc etc are only using the bare hostname.

Public bug reported:
The $PreserveFQDn and $LocalHostname options are not always used when
configured. To be precise, they seem to only be used in messages from rsyslog

In my experience this is only a problem in unity 2d and not in unity.
