Geode Driver
Hardware Support
NOTE: the cyrix and nsc drivers are seriously rotting and some distributions have chosen not to ship them. As such, we have set a milestone to import GX1 support into geode and then deprecate cyrix and nsc. Help is welcome! See below for details.
- AMD Geode NX is not supported by any known driver.
xf86-video-geode
This driver was previously called amd. It was renamed geode to avoid confusion with ATI chipsets acquired by AMD.
- AMD Geode LX (a.k.a. GX3) PCI ID: 0x1022:0x2081
- AMD Geode GX (a.k.a. GX2) PCI ID: 0x100B:0x0030
This is not a typo; both nsc and geode support GX2. However, only geode has up-to-date code, while nsc is deprecated.
xf86-video-nsc
- NSC Geode Media GX (a.k.a. GX2) PCI ID: 0x100B:0x0030
- NSC Geode SCx200 (a.k.a. GX1) PCI ID: 0x100B:0x0504
- NSC Geode SC1400 (a.k.a. GX1) PCI ID: 0x100B:0x0104
xf86-video-cyrix
- Cyrix Geode Media GX (a.k.a. GX1) PCI ID: 0x1078:0x0104
Auto Config support
- LX works since X server 1.5.
- GX2 works since X server 1.7.
- GX1 works since X server 1.7.
See patches on the Ubuntu BTS to implement this on 1.4 and 1.6; should also work on 1.3 and 1.5 with minor adjustments.
Current Status: xf86-video-geode 2.11.5 (released: 2009-09-22)
Known Bugs
Compilation against X server << 1.3 fails since geode 2.9.0 because of a missing header:
geode_ddc.c:31:23: error: xf86Modes.h: No such file or directory
geode_ddc.c:158:50: error: missing binary operator before token "("Might be fixable following Intel driver autoconf methods.
Server-specific Bugs
- With X server 1.7:
- No known issue.
- With X server 1.5 and X server 1.6:
EXA Composite rendering bug: Black boxes X.org BTS
GX2: AccelMethod "XAA" is needed in the Device section of xorg.conf (fixed since geode 2.11.4.1)
AutoConfig only implemented for LX.
- With X server 1.3 and X server 1.4:
Some platforms will freeze when using X -configure: Ubuntu BTS.
Attachments include two patches against x86emu (port blacklist, PCI bus access) that resolve this issue.

PCI patch merged into X core 1.5 tree
- With X server 1.2:
- Cannot compile since 2.9.0 (see above).
Switching to a console using CTRL+ALT+Fx fails on some platforms: Debian BTS Ubuntu BTS.
Attachments include a patch against x86emu (CPUID) that resolves the issue.
