Description From 2003-11-25 10:59:49
libGLwrapper-5.0.1-alt7.
libGLwrapper don't filter video4linux devices while search appropriate GLX 
device. For example, AVerMedia tvtuner & NVidia GeForce 4 (and any other).
In this example libGLwrapper can't find NV in this string (string 84 from 
GLwrapper-0.1.8-nv_and_fglrx.patch) 

if (ainfo && strstr (ainfo[0].name, "NV")) 

because ainfo[0] -> video4linux.:(

Как я говорил, первым идет tvtuner.
Для себя я решил проблему прикладыванием
небольшого патча (прикладывается после GLwrapper-0.1.8-nv_and_fglrx.patch):

Возможно, из-за этого у меня дома рендеринг стал софтовым примерно после
установки тюнера. Проверю.
------- Comment #5 From 2004-05-29 19:13:51 -------
Выбросил тюнер, не загружаю v4l в иксах. Рендеринг по-прежнему софтовый, так
что
v4l в моём случае не при чём.

libGLwrapper-5.0.2-alt2, система Alt Linux 2.4 Master DVD Edition
все то же самое.:(
попрежнему нет 3D при наличии v4l.:(

в Sisyphus больше не используется libGLwrapper, эта подсистема переписана.
