This seems to be more of a problem with the notebook rather than specifically omega's driver. Before I knew anyone else had done this I spent a day or two modifying Nvidia's (at the time) current reference driver to make it work with the Dell Latitude D800s (1920x1200 screen, GFFX Go5650 w/128MB). I had tried both 53.03 and 56.72. By adding the appropriate deviceIDs and matching/adding/removing various pieces between the reference .INF and Dell's 45.81 .INF I was finally able to get it to install and work but I too had the same problem with the screen failing to shutoff in power saving. It would go black but was still obviously powered on. Then, trying to wake it up would result in the whole screen turning pure white and nothing more would happen. Only a poweroff/reboot would fix it. My goal was to avoid paying the extra $1000 for the essentially the *same* notebook (the Precision M60). But I need to support Unigraphics NX and I-DEAS. Unfortunately only the Precision line of notebooks receive the video driver attention (certification) that is sometimes necessary to fix display bugs with these kinds of high-end applications. So far I've purchased around twenty D800s but I may have to bite the bullet and begin ordering M60s from now on if Dell refuses to update their ANCIENT video driver for the Latitude line.
