ArchLinux, xorg 1.7, Nvidia 190.42 => segfault

So there are two independent SIGSEGV's. One related to Xinerama, second related to Gtk applications.

Is xfig a GTK application? xfig causes very reliable crashes (SEGFAULT) for me when trying to access the menus. I found this so annoying, since I'm in the process of drawing floor plans to a new house, so I found a way to make xfig run without crashing: by starting X with startx and having xfig as the only app in ~/.xinitrc...

Thunderbird is also a reliable source for the crash for me, when moving the mouse over the message frame in mails from a certain source (a newsmail from a mobile phone news site).

Oh well, it looks like the source of the problem has been found, so a fix is eminent.

BTW: what WM is everyone using? I've seen a few mention KDE, but can't recall seeing others mentioned. I use KDE4.

Segfault again with xorg patched... So, really seems to be an NVIDIA bug :-(

It sounds like there are a number of different crash problems being reported in this thread. One is due to a buggy change that went into xserver 1.7 that is addressed by the Fedora 12 patch. That patch ought to solve the crash problem but has performance problems that I described in Freedesktop.org bug #25136. The other crashes being reported sound like different problems.

After some more testing, bug seems to only occur with konqueror + webkitkde...

Can't make it crash with firefox...

But with konqueror, i'm looking at a webpage and just moving the pointer (no scroll) can make X crash.

xfig (accessing menus) and Thunderbird (certain mail content) causes crashes for me as well.

Using a completely updated fedora 12, I can confirm:

1. The same issue David Ronis had, though I'm now using:

Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Xinerama" "1"
EndSection

and it works fine.

2. The segmentation faults many have been reporting using xorg 1.7 and 190.42:

I'm running a completely patched fedora (I'm using xorg-x11-server-Xorg-1.7.1-7.fc12.i686). Applications I had open at the time: thunderbird, firefox, gnome-terminal, xchat, amsn, xmms and the gimp. xccreensaver was probably active, I wasn't at my computer and cannot confirm that.

Same Problem here with LFS + BLFS.

Xorg Server 1.7.1
gcc 4.4.2
