    Cool perfomance tweaking cat. 10.10 ubuntu 10.10 (32 bit)

    hi yall,

    i installed the official cat. 10.10 for 32 bit ubuntu 10.10. i am also using a crossfire chain with a 5750 & 5770 and i think its working. therefore, i used the guide here on phoronix.

    i did not install cat. control center. now, is there a way to tweak all those settings manually, like in xorg conf? and what are all the available options to do so, is there a list somewhere?

    my xorg.conf looks like this atm:
    Section "ServerLayout"
    Identifier "aticonfig Layout"
    Screen 0 "aticonfig-Screen[0]-0" 0 0
    EndSection

    Section "Module"
    EndSection

    Section "Monitor"
    Identifier "aticonfig-Monitor[0]-0"
    Option "VendorName" "ATI Proprietary Driver"
    Option "ModelName" "Generic Autodetecting Monitor"
    Option "DPMS" "true"
    EndSection

    Section "Device"
    Identifier "aticonfig-Device[0]-0"
    Driver "fglrx"
    BusID "PCI:1:0:0"
    EndSection

    Section "Screen"
    Identifier "aticonfig-Screen[0]-0"
    Device "aticonfig-Device[0]-0"
    Monitor "aticonfig-Monitor[0]-0"
    DefaultDepth 24
    SubSection "Display"
    Viewport 0 0
    Depth 24
    EndSubSection
    EndSection
    what should i change about this xorg.conf, when i want to have even better performance for games and desktop applications?

    second, is direct2d accel. enabled by default with this driver? and would you recommend to enable it? which different modes exist to accelerate 2d?

    third, how would i configure an automatic switching low power state for 2d and a high power state for 3d? or how can i make a permanent overclocking? i see there are some options in aticonfig.

    fourth, i see the crossfire chain is enabled, but how can i really check if its actually 100% working or being used by an application (for example heroes of newerth)?

    fifth, would you recommend to install opencl driver? what applications will profit of it?

    best regards

    aticonfig --lscs shows me:

    Candidate Combination:
    Master: 1:0:0
    Slave: 2:0:0
    CrossFire is disabled on current device
    CrossFire Diagnostics:
    CrossFire can work with P2P mapping through GART
    Dongle Capabilities: support PASSTHROUGH |INTERLINK_SW_AFR | INTERLINK_AUTO_AFR | INTERLINK_BLACKING | INTERLINK_SUPERAA

    so crossfire is not working it appears!


    aticonfig --lsch shows:

    CrossFire chain for adapter 0, status: enabled
    0. 01:00.0 ATI Radeon HD 5700 Series
    1. 02:00.0 ATI Radeon HD 5700 Series

    the second (slave) adapter is not! in xorg.conf, why?

    Section "ServerLayout"
    Identifier "aticonfig Layout"
    Screen 0 "aticonfig-Screen[0]-0" 0 0
    EndSection

    Section "Module"
    EndSection

    Section "Monitor"
    Identifier "aticonfig-Monitor[0]-0"
    Option "VendorName" "ATI Proprietary Driver"
    Option "ModelName" "Generic Autodetecting Monitor"
    Option "DPMS" "true"
    EndSection

    Section "Device"
    Identifier "aticonfig-Device[0]-0"
    Driver "fglrx"
    BusID "PCI:1:0:0"
    EndSection

    Section "Screen"
    Identifier "aticonfig-Screen[0]-0"
    Device "aticonfig-Device[0]-0"
    Monitor "aticonfig-Monitor[0]-0"
    DefaultDepth 24
    SubSection "Display"
    Viewport 0 0
    Depth 24
    EndSubSection
    EndSection

    if i initiate the second adapter with aticonfig --adapter=all --initial for example, it will be in the xorg.conf but linux will show it as a second master adapter. if i delete the extra screens for the 2. adapter aticonfig --lscc will show:

    Master adapter: 0. 01:00.0 ATI Radeon HD 5700 Series
    Candidates: 1. 02:00.0 ATI Radeon HD 5700 Series

    Master adapter: 0. 02:00.0 ATI Radeon HD 5700 Series
    Candidates: 1. 02:00.0 ATI Radeon HD 5700 Series


    what is wrong here and what is the correct way to get crossfire to work? i think the second adapter needs to be in xorg.conf too, but it need some special options to work as a crossfire slave.

    sorry, at the end it was more like:

    Master adapter: 0. 01:00.0 ATI Radeon HD 5700 Series
    Candidates: 1. 02:00.0 ATI Radeon HD 5700 Series

    Master adapter: 1. 02:00.0 ATI Radeon HD 5700 Series
    Candidates: 1. 02:00.0 ATI Radeon HD 5700 Series
