I just upgraded from RH 9 to Fedora Core 1 yesterday on a Dell Precision 340 with an Nvidia graphics card. I have read the previous thread about Nvidia drivers. I had already installed them from the Nvidia script using the CC_IGNORE_MISMATCH flag, but uninstalled them and installed the rpms at www2.educ.umu.se/~peter/nvidia. The rpms seem to work as well as the Nvidia script so far, but I still have a problem -- none of the OpenGL screensavers work. All fail with the error "Xlib: extension XFree86-DRI missing on display :0.0" (to be clear, this error occurred with the Nvidia-installed drivers as well as with the rpms). Nvidia explicitly states that dri should *not* be loaded in XF86config and I did not do so for RH 9.0. Everything worked fine under RH 9.0. What has changed?
