Bug Description
This is a followup on a bug discussion started in bug https:/
This bugs is related to a crash when loading X, for PC with at least two nVidia graphics cards and using the nvidia-current drivers (195.36.15) with kernel 2.6.32-any version.
In my case the installation was done with a clean install of Kubuntu Lucid Lynx - booting with the two graphics cards and the nouveau driver works fine. Installing the nVidia driver went also fine, but during reboot the computer froze right around the time X should load. The computer is totally unresponsive, only a hard reset allows rebooting.
The booting issue goes away if one of the two cards is removed or, if using a 2.6.31 kernel with the two cards attached.
Note that in my case only one card has two screens attached, the other has non, for GPU computing.
Using the 195.36.24 nvidia-current driver (from ppa) gives the same results.
This bug is still present after applying all available updates for Lucid.
Attached is the nvidia-bug-report, which aggregate most useful information. What I did was:
1) Start from working 2.6.31
2) reboot on 2.6.32 => crash
3) wait 2 minutes
4) hard reboot to 2.6.31
5) nvidia-
In the nvidia-bug-report text file you have aggregated (among other files) the Xorg.0.log and Xorg.0.log.old (just search for 'Xorg.0' to find them). However at the beginning of each log you'll see that the kernel is 2.6.31... In other words during the 2.6.32 boot X did not manage to start logging...

=> apparently there is an incompatibility between current nvidia graphics driver and the new VGA arbiter (not present in 2.6.31 ?)

Same here. Dual NVIDIA Geforce 8800 GTX cards, Lucid Lynx 64-bit Beta 2, after installing nvidia-current drivers with jockey, system will no longer boot. It never even gets as far as writing an Xorg.0.log.
The previous bug report was already about exactly this issue. It's a pity that there is apparently a knee-jerk reaction around here to automatically dismiss any bug report where someone even mentions the NV**IA webs*te...
