Bug 429898

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

skype

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
procedure...

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.
