I started a discussion on a problem I was having with my laptop running too hot
( http://supergamer.org/vl/forum/index.php?topic=6658.msg45548#msg45548 ). I noticed that the laptop's temperature went up a lot when Opera was running, but not when SeaMonkey was running. Modprobing powernow-k8 and setting vcpufreq to ondemand made a substantial improvement in the heating problem. However, Opera still had a tendency to raise the temperature when it was running. (I used System Profiler and Benchmark to track the temperature, but I have some doubts about how reliable it is, especially on a laptop.)

In checking htop, I noticed some operapluginwrapper processes and decided to terminate them to see what would happen. Lo and behold, the computer cooled down and nothing seemed amiss with Opera. Flash is working. I also got rid of the operaplugincleaner process with no apparent ill effects. So now I make sure those operaplugin things aren't running, and things aren't heating up the way they do when they're running.

I don't have this problem on my Athlon desktop. The laptop is an all-NVidia system. I don't know whether any of that is involved.

If any of you are having problems with Opera hogging CPU cycles or making your computer run hot, please see if killing the operapluginwrapper processes helps out. And be sure to report your results.

I'm running Opera 9.51.

yes, I notice operapluginwrapper going amokk also. But I solve it by pressing F12 and disabling Java and plugins. Less annoying flash stuff to see. I turn it on when necessary.

Disabling Java and plugins doesn't prevent Opera from raising the temperature for me. I still have to kill operapluginwrapper and operaplugincleaner. Once I do that, the temperature quickly drops by 15 degrees C. (according to System Profiler and Benchmark).

When I have time I'll poke around in the Opera and Linux forum and see if other people are having this problem. If so, maybe it'll get fixed in the next version. I know that Opera 9.51 fixed an issue I was experiencing.

Do others have any more feedback to offer on operapluginwrapper?

I've tried this, but my htop doesn't even show a operapluginwrapper or operaplugincleaner running.

This is opera 9.50 running on VL Light Beta5

Today when I started Opera Java and plugins were turned off at startup. I guess you have to close and restart Opera if you hit F12 to turn things off in order to have no operapluginwrapper or operaplugincleaner processes running.

So I didn't have to turn off the nonexistent processes this time--hooray! And things have been cool temperature-wise.

M0E-lnx, are you having any heat problems related to Opera? The problem doesn't seem to happen on my Athlon 64 X2 system. I haven't had the Celeron desktop on for a couple of weeks to see what's happening there.

I removed the Opera package right after installation from my laptop (Celeron M) but I have it installed @ work on a desktop PC (old VL-Light candidate box)
