Video toggle button hang, Fn+F4 on Compaq Evo N1005v.

Video toggle button hang, Fn+F4 on Compaq Evo N1005v.

[Christer Backstrom]

Hi All,

I got this video-out toggle button Fn-F4 on my Evo, which totally hang my 
lappy if I use it, no messages and no serial console, no difference if I got 
something connected or not. I've been looking round on the web for the 
solution to this, and found patches for ignoring ff buttons and correcting 
the dsdt, but no go. And Compaq of course gives me the old "Linux is not 
supported" yadi-yadi-yada. I was wondering if anyone has suggestions for 
howto debug this? And to be honest, I'm not even sure this is a ACPI problem, 
but everything else seems to be ACPI controlled. I've seen others complaining 
about exactly the same problem on the Presario900 list (pretty much the same 
computer). On another note: there's a Presario model with almost the same 
config, but with everything working. Anyone know if I can use the Presario 
BIOS? 

Config: linux-2.6.7+dsdt-initrd-patch+ignore-ff-button-patch.

PS. As I'm not getting anything out of the box as it hangs, I'm not attaching 
any files. If someone wants this, I'll post them. DS.

/Chris

First and last Compaq ever. Promise.

You might try booting with 'nolapic'.

Well I'll be d... It works! Thank you so very much. Should I be worried about not having the local APIC working?

Provided your IRQ config is not messed up and all your devices are working,
not really.
Glad to be of help,

Interesting that you never came across the much publicised solution to
this problem (perhaps your searches were too specific). Try disabling
uniprocessor apic, either via a boot time option as suggested by Karol
Kozimor, or in the kernel config itself. The kernel config option is
CONFIG_X86_UP_APIC

Let us know if that works

Cheers

Andrew
