I recently installed the Nvidia-supplied driver (v5336), via Nvidia's installer, against kernel 2.4.22-1.2166.nptl, on a Dell Inspriron 8600. O/S is FC1, all errata (up to 4 days ago). My overall impression has been great, except I see a screen flicker from time to time. Some early monitoring seems to show this is occuring regularly, every 8-9 minutes. $HOME/.xsession-errors and /var/log/messages do not show any warnings or errors at these times. Has anyone seen (and hopefully solved) this problem? I realise this driver is 3rd-party, so apologies if this is considered off-topic. Thanks, Ben
