View Full Version : [ubuntu] X crashes frequently, randomly, not on Live USB

Ok, I've got a rather annoying problem (probably putting it a bit lightly).

Basically, within about five minutes of me logging on to a recently installed and updated installation of Ubuntu 9.10 (on my SATA drive), something happens that has roughly the effect that Ctrl+Alt+Backspace used to. This has happened multiple times, within no less than two installations of Ubuntu. I've always thought that reinstalling an operating system, supposing restarting it didn't fix the problem, would. However, in this case, it seems, reinstalling did no good at all. One possibility, I think, would be that I've installed something, or some things, that conflict either with my hardware (which is already annoyingly conflicted...I'll explain a bit later), or with another package.

The most recent instance, I think, was when I had opened a few tabs in Google Chrome (most recent dev build, as of sometime this morning), and had started loading all but one of the four. When I switched over to it, and pressed enter, within a couple seconds, at most, the screen went black and it returned me to the login screen. I'm fairly sure this has happened more than once on this most recent installation, and probably at least five times in the previous.

You can probably imagine I'm getting tired of this.

I had had a fantastic experience with 9.10 prior to this, but now I worry that the horror stories about 9.10 that have been going around might not be unjustified. This simply can't go on.

If you need any logs, the list of packages, or anything else, don't hesitate to ask. I'm more than happy, in this instance, to attempt to find a way to remedy this life-mutilating problem.

Oh, yes. My hardware. I've got a Dell Optiplex GX280, as you might have seen in my signature...and, yes. I've run a memory test on both of my two gigabytes for hours and hours a while ago, and for thirty minutes or so today (never found any errors at all).

The sticky part? I've got a Pentium 4 670. It's clocked at 3.8 GHz, and Dell, for some reason, has created a BIOS that only allows it to use 2.8 GHz of that. I don't entirely blame them for it...they're a company more for the consumer than the DIYer...

Anyway...when I ran the memory test, it said my memory was clocked at 266 MHz, less than half of what it should be (667 MHz).

Also, when I ran CPU-Z in windows, it came up with the memory clocked at 333 MHz. When I ran some super-exhaustive system info command (can't remember it) in Ubuntu, it showed the memory as DDR2 5300, what it is. It'd be nice to know that I'm only using less than half my memory bandwidth, meaning, with a new motherboard, that my system would be much, much faster, but, still...why all the different stats?

Oh! I forgot to say...the guy I bought this computer from upgraded the motherboard. I've looked all over the internet for info on this board, but, seriously, I can't find anything but prices.

Yikes, tangents.

I hope more than half of this helpful...

Merry Christmas,

Could you post the output of the "lspci" terminal command?

I can't think of anything except maybe the SATA is going bad or something like that. I don't know how likely Intel boards are to that kind of breakage, but I've personally seen that with an nForce board here. Sorry I can't help out more.

I have the same exact problem, and I think I might have found the culprit to be Google Chrome. It started after switching to Chrome, and I have yet to experience it while Chrome is not running. I might be wrong, but that's my guess as of now.
