I would like to try to help you with your issue. I would like you to try to help me understand your specific issue better. The condition where a relatively recent Intel processor locks at around 600 MHz, where the minimum pstate for the package is 800 MHz has been observed many times. However, I am only aware of the condition occurring after a resume from a ...

If you look at the performance index of your card, it's absolutely normal that you get this kind of speed… Nothing Ubuntu can do about this! Note to low-quality reviewers: That's it!

Try changing/updating the default graphics driver. From my experience, installing linux in a mac is better than keeping the default apple software, but as far as gaming is concerned, apple's software is simply better. That is because graphics drivers are better developed in windows and mac osx.

EVGA GeForce 8400 GS. This graphics card is around the same price range as the one you have but it has 1 GB of vram which should be more than enough to watch videos on the internet.

Pulled from: http://askubuntu.com/a/233947 I can't comment on another answer, but from the highest rated answer, it says to echo "disabled" into an interrupt in order to disable an overactive ACPI line. To find which interrupt, run this: grep . -r /sys/firmware/acpi/interrupts/ Then, look for the answer with the high number. Echo disable into that file ...

no need for any external software just try this... sudo hdparm -I /dev/sda | grep Rotation output would be like Nominal Media Rotation Rate: 5400 cheers.

I seem to have proven my above comment incorrect. With perf, you can view system cache information much the same way ps will let you monitor cache hits/misses, which is just as good as anything else, as the cache is fully loaded as soon as enough data/instructions pass through it to fill it. Be aware that linux-tools (the package installed by apt for you to ...

I was also experiencing these exact same symptoms and finally decided to do a little diving into my dotfiles and found the solution by systematic process of elimination. In my case, it turns out that something had gone wrong with the files stored in my compiz configuration cache. Simply deleting the directory and relogging solved my graphics issues: $ rm ...

You should check your swappiness value. Usually it is left at 60. It should be 10 or 15: cat /proc/sys/vm/swappiness You can change it on the fly with sudo bash -c "echo -e 10 > /proc/sys/vm/swappiness" and make it stick with sudo bash -c "echo 'vm.swappiness = 15' >> /etc/sysctl.conf"

No, it just dumps a load of stuff (slab objects and pagecache) from the system cache. If your system is out of memory (and I mean: deep into swap usage, nothing free, hard disk churning) then yes, this might help... But not as much as: Buying more RAM, it isn't expensive or hard to fit. Closing something that's using lots of memory (or tabs from a ...

No, see How do I clean or disable the memory cache? for an indepth answer. Cache is there to be used and to speed things up. So Linux makes full use of caching. If you do this it will takes seconds for the cache to be filled up again. Adding hardware to your system would be more efficient (depending on what triggered your question it might be memory or ...

You can also write command as: echo 3 > /proc/sys/vm/drop_caches The above command will free pagecache, dentries and inodes. And sudo sync is used to to make sure all cached objects are freed as dirty objects are not free-able and the echo operation is non-destructive.

Just for forwarding latency go to SMPlayer: Preferences/Interface/Seeking/ Precise seeking and check this option off.

SMPlayer can be used with mplayer, mplayer2 and mpv you can manually set it to whatever you like, sometimes I do set it myself to mpv for example. Simply replace the default like on the screenshot: To use mpv which is recommended by SMPlayer simply type mpv instead of mplayer. If you don't have mpv installed you can add this ppa with the latest updates ...
