i am running my x server in multiscreen mode. certain applications, e.g.
gitk/git gui crash the complete x server.

i experienced this issue on ubuntu 11.04 with both the default xorg and with
the x edgers ppa packages. none is working correctly.

Hi Tim,

First of all the bug report you linked is about a issue relating both the
blob (nvidia's proprietary driver) and nouveau

Thus:
* Most likely the issue is not nouveau related, but nevertheless take a
look further down

1. We do *not* handle bug reports of the blob
2. The bug report contains almost no information about nouveau.
There are logs of the blob (non relevant to us)
3. Please take a look at "How to report bugs" [1]
4. But beforehand drop by our FAQ [2] and troubleshooting [3] section
5. It appears that the "bug: [mi] EQ overflowing" is already covered [4]

Note:
We are *not* the maintainers of Ubuntu's stack nor the xorg-edgers.
Therefore if you mention them please use the corresponding commits they
are based on.

Therefore:

I'm closing this bug as NOTOURBUG, and please do provide a reasonable
bug report, after you have checked that one does not exist

[2] http://nouveau.freedesktop.org/wiki/FAQ
[3] http://nouveau.freedesktop.org/wiki/TroubleShooting
[4] http://nouveau.freedesktop.org/wiki/TroubleShooting#Igetthe.22EQoverflowing.22error

P.S. I'm a Ubuntu user, to the extent that I do not want to configure
all the userspace by myself. I do configure and build the kernel, libdrm,
ddx and mesa by myself (simple script does the job for me)

sorry for trying to report and resolve a bug, which at least in my case, is
definitely related to nouveau

Yet another relatively long reply but I believe it is necessary

1. How about looking at the log for about 20 secs - you would have easily seen
the issue - "EQ overflow"
2. Then use that information to go through the relevant sections -
faq/troubleshooting
3. And provide a simple clear report indicating the issue and following the
guides (see the bugs section)
4. I would *not* have pointed out to bug report, that is not well defined - not
to mention that your name does not appear in it (i.e. probably lacks
information provided by yourself)

My approach (not only) would be - spend 5(or less) minutes reading, another up
to 5 thinking on how to formulate the issue, and 2 minutes for write up.

I realize I sound like a prick although I'm a bit fed up with some users' *lack
of interest to actually resolve issues* - they just want to report that "it
does not work"

Hopefully you will see some of the positive things that have been said in here

unfortunately, my x debugging capabilities are a bit limited: if i try to
attach gdb to the x process, x freezes, which makes it a bit hard to get a good
backtrace


> I realize I sound like a prick although I'm a bit fed up with some users' *lack

* i experience a bug
* i check the tracker of my distribution and find a related issue
* i subscribe to the bug
* nothing happens
* i stop using one of my crucial applications
* i submit a bug report upstream, pointing to the downstream report
* it initially gets `resolved' as `notourbug'

i am maintaining an open source project myself. but i have never told any of my
users that it is their problem, if my code crashes.

The above has been taken from the latest Xorg.log in the bug report and clearly
indicated that the issue was experienced using nouveau

well, this is the reason, why i am reporting the bug here ... after all, this
is the bug tracker for nouveau,  isn't it?

the first sentence of my bug report was:
"i am running my x server in multiscreen mode"

the subject:
"some applications crash the x server in multiscreen mode"


> > ...

the symptoms are the same:
nouveau + multiscreen + gitk/git gui == crash

> > ...

> * Or try to find a workaround

like stop using gitk? i've been working without it for almost two months ...

... sorry, but i have already spent too much time with this bug today ... will
reinstall ubuntu 10.10 and the proprietary driver, since i need to get some
work done
