Intel X3100: Unusual graphics problems in 3D games

So I have an Intel X3100 (standard issue with third-generation MacBook) for a graphics card. It works — at least, games run at playable speeds — but I've noticed a few odd problems when playing OpenArena.

For example:
* When I stand up close to a wall or other flat surface and look at it, the little icons at the bottom of the screen get clipped by it. Will post a screenshot if necessary.
* In the main menu, the animated logo at the top does not show.
* When rockets explode, a sort of square flashes around the fireball for a moment.

The first and second problems (not sure about the third) did not happen in either Mac OS X or my old distros (Ubuntu 8.04 and 9.04), so I figure I must have done something stupid. Here are the graphics-related sections of my xorg.conf:

Section "Device"
    Identifier    "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller"
    Driver        "intel"
    BusID        "PCI:0:2:0"
EndSection

Section "Monitor"
    Identifier    "Generic Monitor"
    Option        "DPMS"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Device        "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller"
    Monitor        "Generic Monitor"
    DefaultDepth    24
    SubSection "Display"
        Viewport 0 0
        Depth    16
        Modes        "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection "Display"
        Viewport    0 0
        Depth       24
        Modes       "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
EndSection

Section "DRI"
    Group "video"
    Mode 0666
EndSection

Section "Module"
    # Graphics stuff.
    Load "glx" # OpenGL
    Load "GLcore" # ^
    Load "dri" # Direct rendering
    Load "dbe" # Double buffering -- unused?
    Load "i2c" # Monitor info
    Load "ddc" # ^
    Load "vbe" # VESA BIOS (?)
    Load "int10" # ^

    # Font stuff.
    Load "bitmap"
    Load "extmod"
    #Load "freetype"
    #Load "type1"
EndSection

Installed packages related to Intel graphics (pacman -Q | grep intel):

intel-dri 7.4-2
xf86-video-intel 2.6.3-3

Packages related to SDL (pacman -Q | grep sdl):

sdl 1.2.13-3
sdl_image 1.2.7-1
sdl_mixer 1.2.8-3

Also: I've noticed that War§ow takes a long time to start up, but this may be due to it requesting a file containing the newest version number from its website and then timing out. If so, how do I disable that?

The problem is what you didn't do. Read this first http://keithp.com/blogs/Sharpening_the_ … ver_Focus/  and then try to find the best combination (xaa/exa/uxa/gem/kms/dri/dri2) for you.


You need to install an RTFM interface.

Re: Intel X3100: Unusual graphics problems in 3D games

After a recent update, the logo now displays. Gonna give the rest of the game a try.

Update: The icon-clipping thing seems to be fixed as well.
