Default X crash after closing opengl screensaver

If I open up the glmatrix screensaver and run it for a second, when I escape it crashes X. I have the latest kernal and nvidia driver. I'll attach my config and the log.

Default Re: X crash after closing opengl screensaver

I can run glxgears but when I close the app X crashes and I got this in the output:

Default Re: X crash after closing opengl screensaver

I added "noapic acpi=off" to the kernel options and now it no longer crashes after closing glxgears. What do these options do (saw them in another post)? What is the reason for the crash?

Default Re: X crash after closing opengl screensaver

If disabling both of those options fixes the problem then you're hitting a kernel or BIOS bug.

noapic disables the advanced programmable interrupt controller (APIC)
acpi=off disables ACPI support, which is used for power management, SMP support (for Intel CPUs), as well as some other resource management

Thanks,
Lonni

Well, I was able to run the glxgears app with no problem 3 times and then the fourth time it crashed my system again. No it appears it's not totally fixed. Does this have anything to do with running a smp system (hyperthreading)?

I'll need to see an nvidia-bug-report.log to comment further.

Thanks,
