Red Hat Bugzilla – Bug 429898
Skype crashes (nouveau driver)
Last modified: 2009-08-03 03:36:26 EDT
Description of problem:
When Skype is started X crashes and user is logged out
Version-Release number of selected component (if applicable):
Steps to Reproduce:
It was running fine until two days ago, skype is running with nv
driver...GoogleEarth is fine!!! Until two days ago Skype was o.k. and
GoogleEarth crashed X. If I switch to nv driver Skype works but Googleearth
Forgot to say in the report that driver is nouveau
I feel skeptical -- unless you show me useful stacktrace (i.e., it has to be
from open-source application, because otherwise you won't create useful
stacktrace), I will be suspicious that it is bug in skype.
Anyway, please attach your X server config file (/etc/X11/xorg.conf) and X
server log file (/var/log/Xorg.*.log) to the bug report as individual
uncompressed file attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
However, unless I see something obvious in the log, I will be suspicious about
skype, so proving that some open-source app crashes as well would be helpful.
Thanks in advance.

log of a crash
I booted at runlevel=3 then I logged in as user, then I issued startx>crash.txt
1>&2 and then I started Skype. I do not know if any useful can be found in it.
What surprises me that with nv driver is working bit not with nouveau.

That's very simple -- although I have unending respect for nouveau developers,
their driver is just not there YET in terms of stability and maturity.
Actually, I don't see any backtrace from X in the log. What EXACTLY happens,
when you run command
in the gnome-terminal (or whatever is your console emulator in X)?
Something like (this is just an example to show how detailed I wont the
description to be):
- ten seconds nothing, skype is starting,
- panel flashes three times,
- everything evaporates from the screen except for background,
- screen is black, mouse is moving, but even Ctrl-Alt-Backspace doesn't help to
make X working again.
Putting this bug into NEEDINFO
BTW, if X gets to unusable state, you may investigate further your computer
using ssh from other computer. In such case, it would be interesting to see,
whether X actually crashed (i.e., pgrep -f -l Xorg gives no output), or if it is
running whether it takes almost all CPU of the computer (run top and take a look
at the top process to find out).

When I say surprised I do not blame nouveau developers, as I find good
performance but I mean that something strange has happened during some driver
upgrade, but I am not sure as for some time I didn't run Skype on that machine
as I usually a wireless Skype phone....Skype was working with nouveau, then it
started breaking X

No difference if I start Skype from the menu or from a terminal:
1)skype starts with the initial window calling for username and password
2) when I click on o.k. after a very short period a blank screen appears, then I
get the login screen of Fedora calling for username and password
I do not if that is correlated, but after this kind of crash when I stop the
machine I get a blurred screen orange coloured and not a single line of closing
OK, putting this bug officially on probation -- unless you will show me in a
month useful backtrace from some open source application which crashes you X, I
will blame Skype and close this bug as CANTFIX.
Doing as promised.
can be related to bug in Xserver.
