View Full Version : Fedora crashes and takes me back to logon screen

4th September 2007, 06:59 PM
I got the problem, that my fedora 7 sometimes crashes like this. I get a black screen for a second and then the logon screen is displayed, I got to choose a user and enter its password, then my system looks like after reboot. All windows and applications are closed.
The problem mainly occurs when I close Mozilla Firefox, mostly after I was on sites like myspace.
I should mention that for some reason flash isn't working well with Firefox on my system, I usually open flash sites with opera, but sometimes I accidentally click a myspace link in firefox or another site containing flash. I don't know whether it has something to do with the crashes, but for completeness I should mention.
I don't know whether linux is rebooting the x-server or just logging off my user account.
Please tell me what can i do to stop those crashes?

Have you updated to the latest flash version?

I think so, cause I installed flash only two weeks ago, so it should be the newest version

I'm having a very similar problem. Very often, when I close Firefox, the X-server crashes taking my session with it. It seems to happen only when closing Firefox or a tab within Firefox. It may only happen when closing Firefox when several tabs are open.

The error looks like this in Xorg.0.log.old. I guess Xorg.0.log logs the X-Server restarting. At least that is what the timestamps seem to say.

Fatal server error:
Caught signal 11. Server aborting

I personally think it has nothing to do with flash. It happens about 5 to 10% of the time when I close Firefox. I rarely use flash.

Piet85, what does your Xorg logs show? (They can be found in /var/log)

This is the last line of my x-org.0.log:
(II) VESA(0): VBESetVBEMode failed...Tried again without customized values.
I also checked the flash version, it is the latest one, but maybe it's necessary to mention there's also Gnash installed on my system.

Hmmm... I don't think gnash or flash really has much to do with it. I could be wrong, of course, but my problem seems so much like yours, and I don't use flash very much on this machine. The X-server dies when Firefox is closed and the login session is ended. It seems more frequent when multiple tabs are open, and sometimes it happens when a tab is closed.

Maybe somebody who knows will pitch in here. It doesn't seem likely that this is a vanishingly rare problem. Surely somebody else has experienced it.

If you get any further diagnosing this, Piet85, please post here. I'll do the same.

Good luck!

I have exactly the same problem, Are you using compiz ? Because it seems to me that it began to occur after XGL installation.

Hi, I have the same problem but it only happened with IMs like kopete or aMSN. With kopete happens when I try to open another chat window, with aMSN happens when I try to change my display picture from a chat window.

I'm using Fedora 8 + Compiz Fusion + NVIDIA Quadro NVS 140M (I guess I'm using AIGLX) but I'm not sure
