|
I've just got the ati-drivers installed for my Radeon 9800. Score of 2300 in glxgears.
I got a bit confused during the glrxconfig...
I was asked about x11-drg, but I've no idea what that is? In fact there were quite a few questions ...
| Code: | # === OpenGL specific profiles/settings ===
Option "Capabilities" "0x00000000"
# === Video Overlay for the Xv extension ===
Option "VideoOverlay" "on"
# === OpenGL Overlay ===
# Note: When OpenGL Overlay is enabled, Video Overlay
# will be disabled automatically
Option "OpenGLOverlay" "off"
# === Center Mode (Laptops only) ===
Option "CenterMode" "off"
# === Pseudo Color Visuals (8-bit visuals) ===
Option "PseudoColorVisuals" "off"
# === QBS Management ===
Option "Stereo" "off"
Option "StereoSyncEnable" "1"
# === FSAA Management ===
Option "FSAAEnable" "no"
Option "FSAAScale" "1"
Option "FSAADisableGamma" "no"
Option "FSAACustomizeMSPos" "yes" |
that I just couldn't answer. Not a clue what PseudoColorVisuals is! Anybody have any suggestions please?
The other thing is, for xorg, it has the option of compiling with 3dfx and 3dnow... should I use these, what do they really do? And mmx, should that be compiled in?
Thanks,
Erlend
PS: does xorg now run through my GPU? |

Pseudo color visuals are those in which you can change the actual colors that the indices correspond to. Each index maps to a red/green/blue, or RGB triplet that defines the color that will be displayed on the screen. You can change these RGB triplets for each index. Pseudo color visuals are very common in low-end graphics cards, for example, 256-color SVGA cards that let you change the individual colors in the palette and are of the pseudo color visual type.
so setting this option "off" is a good thing to do with your radeon 9800 
btw you're sure you mean x11-drg and not x11-drm, because I really don't now what x11-drg stands for. |

Found out that DGA is Direct Graphics Access, and should be enabled where possible.
I've also read about xComposite, I really like the sound of not having nasty refreshes. I tried enabling it, but it made everything super slow and windows were being partially rendered. Is there anything else I should have enabled?
Here is the change I made to my xorg.conf:
| Code: | # ***********************************************************
# Extensions Section
# ***********************************************************
Section "Extensions"
Option "Composite" "Enable" # draws in an offscreen buffer, then blits to fb
Option "RENDER" "Enable"
EndSection |
I have DGA enabled in xorg.conf, could the two be conflicting?
Also, am I right in assuming that xfixes and xdamage are both enabled by default?
Thanks,
Erlend |

Composite does not work well at the moment. AFAIK it's still under development, and the drivers can have problems when you enable it. Doing so will also disable 3D acceleration. I would just comment out the Composite line and leave it at that for now tbh.

Okay, thanks.
Am I right in keeping DGA enabled just now though?

Yep, that should be OK.

Just out of curiousity... I have read that you can add "Option" "RenderAccel" "true" in your xorg.conf if you have an nvidia card, why only if you have an nvidia card? Is there a similar option for ati? I mean, will ati cards be able to use xcomposite in the future?
Thanks,
Erlend |
