Quanta crashes, takes X along

bitpicker · 03-08-2008, 02:29 AM

Occasionally I work on HTML files for a website. I do that using Quanta Plus 3.5.8.

Presently there's an annoying problem the source of which I cannot locate; when I use the 'Upload Project' function, Quanta crashes and takes the X server along with it. I get dropped to the command line. It's not a problem with a specific project, it happens in all of them.

The Xorg server log contains the following after such a crash:

Code:

Backtrace:
0: X(xf86SigHandler+0x85) [0x80d5a45]

Fatal server error:
Caught signal 11.  Server aborting

I don't use KDE as my environment but XFce. the system is Gentoo with a 2.6.23 kernel.

There is another problem which may or may not be related to this one, at least it's got something to do with FTP, too: occasionally, gftp crashes, too, during some FTP work. In contrast to the quanta problem the problem cannot be replicated with any certainty; I upload a couple of files, it works, I upload another couple of files, it crashes. Crashes can happen at other times, too, when changing a directory, changing the FTP connection etc. In these crashes it's just gftp that disappears, X is unfazed.

Can anyone shed any light on this?

If you're running a compositing window manager (e.g. Compiz or translucency in XFCE), turn it off, restart X, and see if the problem goes away. I've had the X server segfault by running yakuake (a dropdown terminal emulator for KDE) along with translucency in KDE.

Thanks, you're right - disabling compositing makes the error go away. I downgraded to a nvidia driver version which doesn't crash quanta despite compositing being turned on, I'd rather have compositing than the latest driver.

I think this is actually the X server's (or AIGLX's) fault and not the nvidia driver's, because my occurrence of the error happens on an ATI Rage Mobility. Perhaps it's a problem with zero-size windows or something. I don't notice the problem on my main computer which runs a Radeon 9250.

This bug seems to be reported all over the net from users of OpenSUSE, Fedore, Ubuntu, against Fusion-Dev as well as in general Linux Forums.

A thorough bug report that links together the Debian, Fusion-Dev and Ubuntu entries can be found here: https://bugs.launchpad.net/compiz/+bug/243708

I have supplied more detailed information regarding my personal experiences with the bug there.

It would be great if you could share detailed information on what drivers you used/downgraded to in order to work around this problem!

Thanks!
