I've been getting a rather strange issue between Nvidia driver and the linux compatibility. I've tried this with default Fedora Core 4 libraries, default 2.4 version emulation, 2.6.16, FC6, F7, and now Gentoo. With older Linux X11 libraries (eg, those from ports), anything trying to use Nvidia's libGL that installs into the linux compat area will crash immediately. To get this working at all, I had to install the Gentoo linux dist and install with newer versions of everything (except glibc). This will get far enough that it notes things like: NVIDIA: Direct rendering failed; attempting indirect rendering. /sbin/modprobe, as per suggestions and documentation, is symlinked to ../bin/true, and that allows many things to work rather than complaining that the module can't be loaded. Linux glxgears gets roughly the same speed as on native host, but Linux glxinfo reports no direct rendering is enabled, and a number of extensions aren't reported. This means for basically all Linux games and most 3D apps, they get a small fraction of the normal speed. In addition, I have devfs mounted on /compat/linux/dev (also per various suggestions found), but if I run Linux glxinfo or glxgears or something else that loads OpenGL several times, but keeps complaining that it can't enable direct rendering, it erases nvidiactl and nvidia0 from devfs. That also obviously disables accelerated rendering on host unless the files are remade. I haven't seen this issue before in the past, and I've been wrestling around with it for several weeks. I specifically waited until after the latest Nvidia driver release, because I thought it may have been a strange fault on Nvidia's part. I get a little hesitant to post to the mailing list when I get an issue that I haven't seen reported anywhere yet, but given how hard I've been trying to sort this out, I'm not even sure of any other direction to try to get this working correctly. I can't see anything about my configuration that would be affecting the way Linux emulation works, let alone in such a strange way.
