Nvidia TV-out gives kernel panic

Hello fellow Archers,

I am using Arch for years now and encountered a very weird problem. My multimedia machine has a new videocard, an Nvidia 6200 A-LE. With this card, I am unable to use the TV-out. By default, it sets NTSC as where my TV needs PAL-B. I took the xorg.conf which worked with my previous nvidia videocard.

The problem is, when I set this option in xorg.conf:

option "TVStandard" "PAL-B"

my system freezes when starting X. The flasing keyboard lights indicate a kernel panic, but when I do a hard reboot, nothing useful has been stored in either /var/log/Xorg.0.log or /var/log/messages, as suggested in other topics. When I uncomment this option, X starts up just fine (it only gives me a black and white screen due to the default NTSC). The annoying thing is that this configuration worked just fine with my old GeForce 4 card.

Does anyone know what what is causing this issue or how to find it?

Thanks!

Re: Nvidia TV-out gives kernel panic

What video driver are you using?  nVidia proprietary?  Nouveau?  These are the only two that support TV-out I believe, so try the other one.  And file an upstream bug report for the one you're using.

Also, to tell if you've really had a kernel panic, it might make sense to enable the magic sysrq key in /etc/sysctl.conf, and try Alt+SysRq+{R,E,I,S,U,B} to safely reboot your computer.

I am using the proprieraty Nvidia driver.

Thanks for the hint to use sysrq, I'll try that as soon as I can.

Sysrq wouldn't work if there's a kernel panic, not just a xorg crash.

Dheart: Mhm, hence the "to tell if you've really had a kernel panic" in my post.

Re: Nvidia TV-out gives kernel panic

Unfortunately the debugging keyboard shortcuts did not have any effect, so I guess this really gives a kernel panic.
