I can produce the crash reliably within a few days, and on the new kernel it almost always results in a panic with the blinking lights

So it seems clear that the problem is in the nvidia drivers... We could try downgrading it to the 9746 which was the only one wich worked well on my computer, or we could wait for the new driver and see...

Unfortunately no version of any driver has ever been stable for me on this laptop

more debug info for anyone who wants to take it.

I had another xid yesterday (trying to test this and see if I can get more info out of the kernel panic). This time though, it did not lead to a lockup, just a black flicker of the screen. I thought this may be because this time it's L0->L0 instead of 1 to 0 or 2 to 1

I'm trying to be patient. Though this bug is still not fixed for me after a year of use. I'd like some feedback as to the next step for helping you guys solve this problem on hp laptops.

I am currently using XFCE with composing enabled, and ipw3945. This seems to be working. Maybe that was a bug in Beryl? Or maybe it's just because xfce takes less video resources.

[mlfarrell]

I believe beryl triggers a bug in one of (bios, nvidia, wireless driver). But I can't figure out which one.

I almost never completely lock up anymore (but I still can). However I still get frequent xid's which are coupled with screen flickers/corruption, wireless shutdown (until reboot) and god knows what other problems.

I just upgraded iwlwifi today and i'm gonna see if that helps.

It seems that 100.14.23 + compiz-fusion is more stable than 100.14.19 + beryl... some minor issues here, but no freezes for now (it's more than a week that I am using it).

[mlfarrell]

beta drivers fixes all xid's on my laptop. will report back here if I see more of them

update: no, never mind. I didn't lock up but I got these yesterday on 169.04 coupled with a black flicker
