Nouveau - Jul 2011 - [Bug 39098] New: X segfaults when running a Wine program while 2 screens are, or have been, in use.

https://bugs.freedesktop.org/show_bug.cgi?id=39098

           Summary: X segfaults when running a Wine program while 2
                    screens are, or have been, in use.
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: albertpool at solcon.nl
         QAContact: xorg-team at lists.x.org


When I'm running on 2 screens (extended desktop via XRandR) or had a 2nd
screen
connected during the same X session, X segfaults when running a Wine program.
It can take a minute before anything strange happens, but it can also happen
immediately. Sometimes X locks up, and sometimes X restarts suddenly.
On Ubuntu Maverick it happens sometimes, but on Natty it happens always. And I
don't like to downgrade just for using my Wine programs on 2 screens.

Xorg.0.log: http://pastebin.com/AzVruT8d

dmesg shows absolutely nothing about the crash. The only thing that appears in
dmesg after the crash, is that I've pushed Alt-SysRq and K, and that the
kernel
had killed X because of that sysrq magic key.

It happens when running Nouveau, but does not happen with the proprietary
driver. Probably this is because the proprietary driver does not use XRandR.
I cannot use that driver; it contains a bug which makes it impossible to run
some of my Wine programs on 2 screens.

It happens with all Wine programs I've tried. When there has not been a 2nd
screen connected during the whole X session, it just works.

lspci: http://pastebin.com/Ks3ri3jZ
Intel Core 2 Duo 1667 MHz, 3GB RAM.

HP Pavilion dv6730ed laptop. The second screen, connected via VGA, is an ADI
Microscan LM-1564 CRT monitor, with resolution 1024x768 at 75Hz set. It is
capable
of 1280x1024 but I don't like that resolution; with this one, the text is
just
as big as on my laptop screen.

I hope that I've given enough information. Note that this may also be an
XRandR
or X server bug.

By the way. If it happens that X does not segfault, I am not able to extend a
window from Wine over the second screen. There's also a Wine bug involved
here,
but as it works with the blob I think there's something wrong with Nouveau
that
prevents me from extending that window. Native Linux (GTK and Qt) windows just
extend without problem.

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
