Re: I can't set up dual monitors with TwinView/Xinerama/Separate X
Thanks for trying it, penggull. I'm happy to hear that the new driver fixed the DisplayPort problem. As for your other two problems,
#1: Please run "nvidia-xconfig --mode-debug", restart X with both monitors attached, and then generate and attach an nvidia-bug-report.log.gz file.
#2: Please describe "kaboom" in more detail. When the kernel is upgraded, you'll need to reinstall the driver to build a kernel module for your newly-installed kernel. Similarly, if you upgrade the X server it may replace libglx.so with Mesa's, so you may need to reinstall the driver to fix that. This should all be documented in the README, so please let me know if the documentation was insufficient.
