X goes black and utilizes 100% CPU
1 Attachment(s)

I've got a problem in my hands that I seem to be unable to fix.

When I use the nvidia graphics driver, my X will not launch properly. When I type "startx" it starts up and my screen turns black. X utilzes 100% CPU at this time and my console is completely wasted. I have to log on using ssh and reboot from there.

My hardware is:
AMD Athlon XP 2400+ CPU
Abit NF7 Motherboard ( nForce2 based )
Gainward Geforce4 MX460 Graphics
1 GB of RAM.

My software is:
Gentoo Linux 1.4_r4, 2.4.20-gentoo-r4 kernel
nvidia driver 1.0-4363 (I've also tried 4349 with the same results)
nvidia kernel modeule loaded

My /var/log/XFree86.0.log is attached and my /etc/X11/XF86Config will come in my next post.

I got some assistance from some guy on the Gentoo user mailing list, so, from what I know the next thing in this log should be 2D support starting up, but it never does.

Any assistance you might be able to give would be really helpful.

And here is my XF86Config..

Of course, I forgot to mention a couple of things..

agpart and dri support is not compiled into my kernel. I've also tried compiling completely without framebuffer support but that didn't make a difference either.

I have exactly the same problem, only on a nforce2 based Shuttle SFF PC.

Also using Gentoo 1.4 and tried various driver versions.

Andy, any ideas? I thought the drivers would be right at home on nforce2 hardware!

Just thought I'd post and say problem solved -- the 'IgnoreDisplayDevices' option worked perfectly.


Spirit[Si] 05-09-03 11:09 AM

Just tried that option, nu luck. Still the same problem.

As an update -- I actually used the 'IgnoreDisplayDevices' and another fix at the same time and through experimentation discovered I need both to get X to work on my Nforce2 system.

To the line that boots your kernel add: pci=noacpi pci=biosirq

I found this in these forums, thanks to other Nvidia Linux users.

Andy, it might be worth adding this to the FAQ.

Thanks Martigen, this worked for me too :) You're the man !!

Now to the next step.. lets try some games :)
