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 2.11.9 (released: 2010-08-23)
Known Bugs
Compilation against X server << 1.3 fails since geode 2.9.0 because of a missing header:
