Comment 25 for bug 507233

To people having this problem with Alienware m15x,

I seem to find a way out to stabilize the problem. Ubuntu 10.04 with (almost) latest updates

Linux Kernel 2.6.32-22-generic
Nvidia driver currrent 195.36.24 (through ubuntu package)
xserver-xorg 1:7.5+5ubuntu1
xserver-xorg-core 2:1.7.6-2ubuntu
xserver-common 2:1.7.6-2ubuntu

has been running on my M15x for a week without any problem I encountered before. The flash version is 10.1 (released days before, but it's not the cure I suppose since the problem is gone days before its release).

Basically I upgraded to 10.04 in late April, but the problem persists. My problem has been the crash of x server when playing flash in Firefox for a few minutes, although it suffers from random crash when using other applications, mostly when a drawing operation using OpenGL is underway.

The problem was gone like a miracle two weeks ago. To verify it I play several flash videos on youtube simultaneously for several hours. A few days later, my GPU fan suddenly had a little problem and I asked DELL to come to help me with it. During that time, I noticed that guy unplugged the power jumper of the GPU fan (which is on the right hand side if you turn the notebook upside down with the battery side near you, the power jumper is just visible). Later he plugged it back again and left. That night I found the old problem came back again. I remembered what the guy did, removed the undercover of the laptop, and pushed the power jumper so that it fits tightly. Then I opened the computer and tested it with several flash videos. The problem is gone once again.

Therefore, I think that what Anders Aagaard says is correct. There can be some hardware problem, most likely power supply, with the laptop.
