"It appears that there's a big power management regression in the Linux kernel for the 2.6.38 and 2.6.39 development releases, including the kernel to ship with Ubuntu 11.04 next week. It's reportedly causing a 10~30% increase in power consumption on many laptop computers."
Source Source 2 anyone else feeling this? This post has been edited by zy_xcup: Apr 23 2011, 11:09 AM |

Nope. I've used 2.6.32, 2.6.35, 2.6.36, 2.6.37 and 2.6.38. I get similar battery life on all of these. Didn't try 2.6.39 tho 'coz liquorix sauce is still on 38  |

Hi guys.
I haven't been around for the last couple of weeks, so I apologize if I missed any questions addressed to me. Just let me know if I missed anything. Also, I have a question. Any of you guys run Linux on new Sandy Bridge chipsets? I'm building a rig, and am wondering if I should bother adding an Nvidia card. I don't play games, and the only use for a gfx card would be VDPAU acceleration for HD videos, but seeing as the new Core i5/7 chipsets already have very decent acceleration, I'm thinking a separate GPU isn't needed. I know early Sandy Bridge performance was buggy, but I'll be getting a mobo with an updated BIOS/UEFI (after the recent recall) and will also be running a new kernel. Can someone kindly point me to some Sandy Bridge reviews for Linux that are NOT from Phoronix? (I don't hate Phoronix, but I'm more interested in daily real world usage, not isolated benchmarks) Thanks in advance. |

The PSU bought from one of the seller here in LYN at the price of RM3xx, a derivative model from PC Power and Cooling model Silencer 750 Quad (Black) very quiet PSU I can say.

@scorps
What packages did you install? For pulseaudio on Debian (and possibly Ubuntu and other Debian stepchildren), this is the absolute minimum you need, as far as I know (just pulse and basic libs .... no plugins, bluetooth, etc). For ArchLinux or Gentoo, you find the current libsdl via pacman/portage. Not sure about other distros yet. As root (or sudo); CODE apt-get install pulseaudio paprefs pavucontrol pulseaudio-module-hal pulseaudio-module-x11 pulseaudio-utils libasound2-plugins paman pavumeter pulseaudio-esound-compat libpulse0 libsdl1.2debian-pulseaudio You should also have something like this added to your /etc/asound.conf (ref: Debian Wiki) CODE pcm.pulse { type pulse } ctl.pulse { type pulse } pcm.!default { type pulse } ctl.!default { type pulse } If you still can't get it to work, I suspect a permissions problem, or maybe false detection of your sound hardware. If so, do this in terminal and paste output here; CODE cat /proc/asound/cards Some further reading: (credit: #! forums) http://pulseaudio.org/wiki/PerfectSetup http://forums.debian.net/viewtopic.php?t=12497 Edit: ...and if you still get permission errors (ie: Access Denied), try reading this (it's a 3 yr old article, though) http://tuxicity.wordpress.com/2008/03/15/d...nd-pulse-audio/ This post has been edited by G-17: May 13 2011, 04:23 PM |
