I never heard that anybody solved this issue, but I read that many people have this issue too. On my computer there are only 3 GB + 768 MB of 4 MB available. The graphics has got it's own framebuffer, 256 MB, but IIRC I once have seen that the framebuffer is 512 MB. I guess I can see it running NVIDIA settings, but at the moment I can't run it, because I'm using the nv driver. IIRC memtest86+ did always show the complete memory on my machine. I don't care, since it doesn't make a difference if I got 4GB or 3.8GB. However, I read often about this 8GB issue, for different distros. And it where definitive threads about 64-bit architecture, not about 32-bit and PAE issues. Regards, Ralf
