libxext fills up .xsession-errors log files

[Jonathan Riddell]

libxext can write debug output, and it can write so much of it that it fills up .xsession-errors t be several GB and fill up the hard disk (or the equivalent file with lightdm).

error is "_xgeWireToEvent: Unknown extension 148, this should never happen"

[TEST CASE]
Install Plasma 5 on utopic
Use it for a while
Notice that ~/.xsession-errors is filling up saying "_xgeWireToEvent: Unknown extension 148, this should never happen"

with the new packages this will not happen

Herrlich, resolved for Vivid.
Should I put the Vivid alpha on my parent's laptop? May I start telling them to install and configure everything?

Is there any solution for Utopic?

[Jayesh Bhoot (bhoot-jayesh)]

Is there any solution for 14.10? I am not too willing to switch to Vivid Alpha at the moment, but this bug has become annoying now.

I'm suffering the same problem and I've applied the suggested upstream patch in my personal PPA:
https://launchpad.net/~tanty/+archive/ubuntu/ppa/+packages

However, I don't think this is a proper fix for the problem I'm observing.

When the problem was happening and tons of

error is "_xgeWireToEvent: Unknown extension 148, this should never happen"

messages were spitted, everything was going much slower in the affected application.

With the fix, the application now is mute about this problem but it is still clearly slower. Hence, the error is still happening it is just that we are not seeing the error messages any more.

Is this error a regression in libXext ?

In my case, I'm specially seeing it in a custom compilation of epiphany, the GNOME Browser, from upstream. It seems to be affecting webkitgtk+ ...

I've just upgraded from Trusty and I was not suffering this problem before with the same custom compilation of epiphany.

[Andres Gomez (Tanty) (tanty)]

It seems I'm hitting 2 bugs at the same time since some of my performance problems with WebKitGTK+ seems to be caused because of this bug:

I've uploaded this again to the utopic proposed queue.

Sorry if it is obvious, but is the fix included in 5.2? The problem is still present there.

[Jonathan Riddell (jr)]

I installed kubuntu plasma 5
I installed kdm and set it as default login manager (so it would output to .xsession-errors)
I installed libxext6 from utopic-proposed
I rebooted and logged in
.xsession-errors was pleasinly free of spamming error messages
