New Installation, UXA with hal?

I have successfully installed Arch last night through the guidance of the wiki.
The issue I'm having is with Intel gfx, which I'm sure everyone knows about.

The thing is, I am able to fix this issue in Ubuntu with kernel 2.6.30.rc5 & the latest intel drivers (x-swat) using UXA in Xorg.

How do I go about implementing this in Arch? Is it even possible?

I'm primarily concerned of how to use Uxa without a xorg, since I'm using hal to autodetect?

Thanks in advance!

Once again... xorg uses HAL for INPUT DEVICES ONLY. If you want to specify UXA for your video card, you will need to use xorg.conf.

Re: New Installation, UXA with hal?

@tomk, that is not entirely true.

you need to setup the intel driver under xorg, but from the intel driver manpage: EXA defaults when KMS is not enabled. if you enable KMS, UXA will default. ive tested this removing any accelmethod from my xorg. both KMS and no-KMS boot correctly, picking exa or uxa when expected.

@xoey7, if you want UXA withouth KMS, read the manpages for the intel options in the device section at xorg.conf (man intel)

if you want UXA with KMS, just search the forums on how to enable KMS, UXA will run by default.

Well, I'm using no Xorg.conf because if I do, x freezes with a black screen. I disabled what was needed to be disabled from the wiki, and tried 2 of the methods to make working xorg.conf and they didn't work.

Re: New Installation, UXA with hal?

here's mine, its minimal, so it should do: maybe you need to modify a bit the device section

Section "ServerFlags"
    Option        "DontZap"    "off"
EndSection


Section "Files"
    ModulePath   "/usr/lib/xorg/modules"
    FontPath     "/usr/share/fonts/misc"
    FontPath     "/usr/share/fonts/100dpi:unscaled"
    FontPath     "/usr/share/fonts/75dpi:unscaled"
    FontPath     "/usr/share/fonts/TTF"
    FontPath     "/usr/share/fonts/Type1"
EndSection

Section "Module"
    Load  "GLcore"
EndSection

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    VendorName  "Intel Corporation"
    BoardName   "Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
    BusID       "PCI:0:2:0"
        Option      "MigrationHeuristic" "greedy"  #only works when using EXA. better performance

EndSection

Section "Screen"
    Identifier "Screen0"
    Device     "Card0"
    Monitor    "Monitor0"
    SubSection "Display"
        Viewport   0 0
        Depth     1
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     4
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     8
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     15
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     16
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     24
    EndSubSection
EndSection

Section "Extensions"
    Option "Composite" "Enable"
EndSection

Re: New Installation, UXA with hal?

@eldragon, thanks for the config. I will look over it more in depth when I get home.

EDIT: Should I have hal running or not when using a xorg.conf?
