[SOLVED] HP dv6 Problems

I recently installed Arch on my HP dv6 laptop. Everything seemed to just work, but now, several days later, I've noticed some problems. Firstly, when I first boot the machine, it doesn't get past the "Configuring virtual ttys" stage more than half the time. Sometimes it works and boots normally, but other times the screen goes black (with a backlight). However, the system boots correctly regardless, as I can blindly type my username and password followed by a sudo poweroff and the computer will shut down. Not quite sure what's causing this, as I've tried booting with various peripherals unplugged with no success, so that doesn't seem to be the problem. Additionally, the screen doesn't turn back on after resume from a pm-suspend. Unlike the problems on boot, this happens every time I try to suspend, and there is no backlight. Anyone have an idea of what this could be?

About the resume problem. I have the same.
With ATI drivers above 11.4 the screen never worked after suspend.

Re: [SOLVED] HP dv6 Problems

Could the black screen be a kms issue?

Tried disabling KMS in the boot line. It didn't work, and I need KMS because I'm running X.

Re: [SOLVED] HP dv6 Problems

Maybe you should try baking kms (the video driver that is) into the initramfs rather than disabling it.  With my Intel card, it will pull that kind of crap from time to time if I don't have i915 included in my initramfs.

Tried that. Still no luck, but at least now KMS is started earlier so the shutdown->restart->repeat cycle goes faster tongue. But in all seriousness, I'm probably going to try Catalyst and just disable KMS altogether.

Re: [SOLVED] HP dv6 Problems

That may be a good idea... whatever works, right?
