Re: Debian 2.6.5 nvidia driver issues
Unless you've also upgraded X, the errors you get should have been there in your previous configuration as well. The speedo error is probably caused by incorrect settings of either your fontpath in XF86Config or the xfs configuration, I can only assume that the pex5 and xie extensions are in fact missing. Please post your XF86Config and the full X log so we can have a look at it.
Have you dealt with the 4K stacks issue, by the way? (Search this forum for more information if necessary.) Also, check whether you are using the libraries that came with the driver, and not the X ones. (See the README included with the driver for a detailed discussion.) Uninstalling the driver completely before re-installing might solve some issues here.
