Hi List, just wondering which driver I need to be looking at / for that deals with the laptop's external video connector. Background - went to deliver a presentation last week and found that there was no way to get any video output to the external D-15 connector (hooked up to a video projector). Eventually I re-booted to windoze 7 and all worked just fine - major embarrassment after telling everyone how great Linux was. The laptop has a nvidia GTX 460M card and I use the el-repo kmod-nvidia-295.59-1.el6.elrepo.x86_64 and nvidia-x11-drv-295.59-1.el6.elrepo.x86_64 I do have compiz-0.8.2-24.el6.x86_64 and compiz-gnome-0.8.2-24.el6.x86_64 running but as these should not be dealing directly with the hardware am not thinking they should matter. Not sure where to start trouble shooting - I tried lots of different screen resolutions via the System > Preferences > Display but no joy getting any signal out to the external connector. This laptop does have an hdmi socket but I was not using that, I thought the good old fashioned D-15 video plug should "just work" (tm). The function key <Fn> <F8> did toggle the laptop screen off and on and varied the resolution of the laptop display but never any output on the external connector. I booted the laptop with the display not connected and then tried connecting it - no joy. Then rebooted with it connected and tried power on and off two times but never any signal on the external connector simply booting into w7 and it immediately worked Any ideas of what magic foo I need to get this working would be appreciated. TIA Rob
