fedora 12 - hp pavilion dv7 - flickering image and reboot issue


hello to everybody,

I successfully installed a fedora 12 64 bit distro on my hp pavilion dv7-3020el (VT325EA).

Had a minor issue with headset that I solved thanks to this forum. But now I have two problems that I don't know how to solve...

1) when I start the pc the first thing that appears is a message of cpu cooling failure, the boot stops on this message until I press enter as requested by the message. This happens only if I closed my last session from fedora system, not if I switched off the pc from Windows. Any ideas?

2) I start the system and everything looks fine, but when I switch user the screen begins to flicker and I have to reboot to have things right again.
The flickering happens also when I switch off the pc, the last messages fedora gives while going down always appear flickering. I installed the nvidia drivers using easy life.

Tell me if you need more info, I'm not a total newbie but I'm a normal user without much knowledge of the heart of the system.

Thank you

Is acpi running? Check with
pgrep acpid
Is a fan running?

In linux, the fan is run by acpid. There's a catch-22 type thing here because acpid is not running on startup or shutdown. My laptop boots with the fan at full force, and then slows when acpid takes over. I guess yours is off. Try the Fedora lists, and observe fan behaviour closely on powerup. When you see that message, does it halt? Is a fan running then?

The temperature message thing only happens when I restart the system after having switched off from fedora, and also if I had run the system for 5 seconds.

When I use fedora the fan goes on without problems and the temperature (felt by hand) is not high at all.

To me it seems more like a fault in the way fedora manages the switch off than a real problem in fan management. There's no issue with cooling, but the system comes up as if it were switched off abruptly by a security-temperature-abrupt switch off.

I'll try also on fedora lists. Thanx anyway...

All the basics are right. It's probably a 'note to self' or some config setting. Remember the first rule of maintainance
1. If it ain't broke, don't fix it :-P.

The other thing you could do is run lm_sensors which checks for sensors and loads approipriate modules. Then make sure those modules are in your initrd. Forget how to make initrds in Fedora, mkinitrd has a man page.
