Booted to run level 3 with the 126.96.36.199-pclos5 kernel. Dkms again failed to build the nvidia 173.xx driver. Tried the nVidia d/l installer with version.h in place in full sources, and got;
ERROR:Unable to determine the version of the kernel sources located in '/lib/modules/188.8.131.52-pclos5/source'. Please make sure you have installed the kernel source for your kernel and that they are properly configured: on Red Hat Linux systems for example, be sure you have 'kernel-source' or 'kernel-devel' RPM installed. If you know the correct kernel source files are installed, you may specify the kernel source with the '--kernel-source-path' command line option.
Retried the command with --kernel-source-path /usr/src/linux parameter, after making sure the link pointed to the correct sources directory. Got the same above error.
Uninstalled the kernel source, and installed the kernel-devel package. Dkms still fails to build the 173.xx package with this kernel,... but the nVidia d/l package now builds... and I am currently still running with the 184.108.40.206-pclos5 kernel and that driver installed.
So far the one item that seems not quite up to snuff is glxgears, which gives 3000+ fps with the 220.127.116.11.tex5 kernel, but with this kernel;[root@fatman ~]# glxgears
5774 frames in 5.0 seconds = 1154.772 FPS
6354 frames in 5.0 seconds = 1270.696 FPS
6611 frames in 5.0 seconds = 1321.870 FPS
6921 frames in 5.0 seconds = 1384.167 FPS
7127 frames in 5.0 seconds = 1425.357 FPS
6899 frames in 5.0 seconds = 1379.329 FPS
6892 frames in 5.0 seconds = 1378.122 FPS
Other than that everything seems to be working so far. Edit:
After playing about a bit getting VBox setup for this kernel, and testing my video players and such, re ran glxgears;[root@fatman ~]# glxgears
20916 frames in 5.0 seconds = 4183.042 FPS
21411 frames in 5.0 seconds = 4282.139 FPS
21527 frames in 5.0 seconds = 4305.304 FPS
21336 frames in 5.0 seconds = 4267.135 FPS
20982 frames in 5.0 seconds = 4196.236 FPS
21573 frames in 5.0 seconds = 4314.500 FPS
21408 frames in 5.0 seconds = 4281.247 FPS
21415 frames in 5.0 seconds = 4282.621 FPS
21541 frames in 5.0 seconds = 4308.126 FPS
Now that's looking more like what I expected.
