  1. Re: HOWTO: Improve NVidia Laptop Graphics Performance

    It's not very useful these days but, there is still scripting to be had. You can use the following two commands to toggle the max performance vs. adaptive on and off:

    [ubuntu] Re: Dual Wifi - Tri-Wifi?

    Like I said, it's called bonding or sometimes multiplexing. It's possible to do with wired network cards and I don't see why it wouldn't be possible with wireless cards. It's non-trivial to setup...

    [ubuntu] Re: Dual Wifi - Tri-Wifi?

    I think you are trying to achieve something called bonding. I've never hear of anyone doing it with wifi cards and I don't know if it's useful to do in a home setting but, here is the wikipedia page...

    [ubuntu] Re: Ubuntu 10.10 & SSD's

    The reason people would recommend not using ext3 is because of the journaling. ext4 is also journaled so there is no reason to choose it over ext3. Having said that, modern big name SSDs (Intel,...

    [ubuntu] Re: CPU usage in system monitor.

    That CPU has hyperthreading and, in userland, it's presented as 2 "CPUs". Under the covers, the kernel does know that it's not 2 physical CPUs and will act accordingly. You should be able to run...

    Re: 64 vs 32-bit

    There is no need to install 64-bit just because you have a 64-bit processor. As mentioned above, you can still use 32-bit with PAE but, it might not even be necessary. When you restart the...
  9. [all variants] Re: CPU frequency scaling always enabled, how to disable

    That's not quite true. It used to be the case that the ondemand governor would, by default, shoot the CPU to max speed with very little provocation and keep it there. When that was true, it was...
  10. [all variants] Re: CPU frequency scaling always enabled, how to disable

    mc4man has given some really great advice on this. Your info says you are running 8.04 but, you state you are running KDE4 so, I have to assume you are running a later version of Ubuntu. If you are...

    [other] Re: In 2010 is 64 bit the way to go?

    I was a long time holdout when it came to 64-bit. For years I ran 32-bit with a PAE kernel because I didn't want to deal with the "hassles" of 64-bit. With 10.04, I took the plunge and went 64-bit....

    [SOLVED] Re: Multi-Core+Multi-CPU

    The output of /proc/cpuinfo is showing that you only have a single physical CPU with 2 cores. I'm fairly sure that Atom CPUs lack the hardware needed to be placed in a multi-socket board.

    You will probably need "-march=686 -m32" instead of "-arch=686 -arch=x86_64". That will make 32bit binaries that are capable of running on almost any machine. That doesn't mean they actually *will*...
