    Alternatives to Unity

    Ok, maybe this is more venting and advice giving than advice getting, but I'm yet another person for whom Unity doesn't 'work' and am curious what other people's sentiment is out there. I'm not...

    [all variants] Re: AMD/Intel Hybrid Graphics works !

    My system seems stable with Catalyst installed but the original xorg.conf in place. This is a good setup for me because it seems to be using somewhat less power (no idea why) and, when I want to use...

    [all variants] Re: AMD/Intel Hybrid Graphics works !

    Hi Niccola:

    Again, thanks for the info, though that had some adverse effects for me (see below).

    Some info I acquired on power usage with Catalyst. I had run a test earlier without Catalyst in...

    [all variants] Re: AMD/Intel Hybrid Graphics works !

    Well, tickle me pink, this time going through the instructions, Catalyst seems to have installed properly!

    Powertop reports, at times, lower wattage used than I've ever seen before, but the power...

    [all variants] Re: AMD/Intel Hybrid Graphics works !

    Hi Niccola: Thanks for letting me know that the OpenCL software isn't needed. Best not to have useless software clogging my system. I've removed it (it did create some problems by installing...

    [all variants] Re: AMD/Intel Hybrid Graphics works !

    I tried to use these instructions to install the new Catalyst 12.6, which should be appropriate for my Radeon HD 6700M graphics processor.

    On a first run-through, X11 fails to work and I need to...
  7. [ubuntu] Re: Increase battery life on HP laptop w/ dual graphics

    A bit of an update. I've discovered that Ubuntu is MORE energy efficient than Windows, at least on the best test I've run.

    I finally had time to run a test to see how much better Windows is in...
  8. [ubuntu] Re: Increase battery life on HP laptop w/ dual graphics

    Thanks mastablasta!

    I'll have to give that a try when I have an afternoon free. About to leave on vacation, so probably not for a while.

    I did discover some instructions for installing and...
  9. [ubuntu] Re: Increase battery life on HP laptop w/ dual graphics

    Hi N0oki3:

    Thanks! I did try switching settings in the BIOS. I get options of dynamic vs. static graphics. I gather dynamic means that the needs of applications will determine which card is...
  10. [ubuntu] Increase battery life on HP laptop w/ dual graphics

    I have a dual boot with Win 7 and Ubuntu 12.04. The laptop got about 3 times the battery life with Win 7 as with Ubuntu.

    I suspect part of that is that Ubuntu is running the Radeon graphics card...
  11. [ubuntu] Re: Problems installing proprietary video drivers on dual card laptop

    Interesting. I entirely removed the proprietary drivers from my system. Now, 3D graphics seem to work. It looks like xserve-xorg-video-radeon, which is installed, provides some 3D and was being...
  12. [ubuntu] Re: Problems installing proprietary video drivers on dual card laptop

    Played with it some more. I get the above mentioned error when I try to directly install the proprietary FGLRX driver post-release update.

    I SEEM able to install the proprietary FGLRX driver...
  13. [ubuntu] Re: Problems installing proprietary video drivers on dual card laptop

    Hi zvacet:

    Yes, what I meant was that when I tried to install the driver from Additional Drivers, I got the following error in /var/log/jockey.log:

    WARNING: /sys/module/fglrx_updates/drivers...
  14. [ubuntu] Problems installing proprietary video drivers on dual card laptop

    So, I'm taking the leap & trying Ubuntu on a laptop. Pretty good, but when I try to install the ATI / AMD proprietary FGLRX, installation fails. I get this error:

    [ubuntu] Port knocking not working

    So, I tried to implement a basic port knocking scheme on an office desktop that is getting a lot of break-in attempts. But, simple though the scheme is, I can't seem to make it work. Maybe there's...
  17. [SOLVED] Re: EEK! An Open Port! Is security compromised? Is it really open?

    Hi KevDog:

    Thanks for your input! You were right that the port bumping in ssh did not cause my problem. The problem, as I mention in another thread, was due to the difficulty of de-banning...
  18. [ubuntu] Re: SSH repeatedly locked out by denyhosts after UFW install

    Hi folks: Thanks for all the input! Nothing seemed to work, but I finally figured out that the sole problem was denyhosts itself, not something w/ the firewall.

    I would, for example, disconnect...
  19. [ubuntu] Re: SSH repeatedly locked out by denyhosts after UFW install

    Hi folks: The desktop is at my workplace, and I'm currently at home. I can't access it remotely because of this problem.

    When I'm next at the office (likely soon), I'll try flushing the...
  20. [ubuntu] SSH repeatedly locked out by denyhosts after UFW install

    Hello! I experimented with going to UFW, after reading the sticky in Security Discussions. After turning it on w/ GUFW, *and even after allowing SSH access using the preprogrammed GUFW rule to allow...

    Ok, I'll bump my new problem to a new thread.

    CharlesA: Thanks! I now have several reasons to think the address is legit.

    cariboo907: You're right, the desktop is a personal research machine at my workplace.

  23. [SOLVED] Re: EEK! An Open Port! Is security compromised? Is it really open?

    Ok, I think I may have figured out what is happening. Apparently the ipaddress for my laptop is a private one, so when it goes outside to the network my desktop is on, it gets rewritten. The...
  24. [SOLVED] Re: EEK! An Open Port! Is security compromised? Is it really open?

    Hi CharlesA: Yup, in GUFW, I activated the preprogrammed SSH allow for Anywhere & then rebooted. This really is perplexing, esp. given that the problem seems to persist when I turn off ufw with...
  25. [SOLVED] Re: EEK! An Open Port! Is security compromised? Is it really open?

    CharlesA: Thanks for explaining how to read this info! It sounds like there aren't a lot of services listening, which is good. I wonder why nmap seems to think there are 15 services w/ open ports?...
