Description Shlomi Fish 2012-07-01 10:13:09 UTC 
I'm using Mageia Linux Cauldron on a Core i3 machine with KDE 4.8.95. After I run "gdb empathy", type "r", wait for empathy to crash and then type "q" in the gdb prompt, then X crashes with this backtrace:

I've been getting many other relatively frequent crashes recently (including using LXDE) and it's annoying.

Please fix it. Let me know if I can prove of further assistance.

My computer's specs are:


My primary machine is a desktop machine with a:

    An Intel Core i3 CPU (x86-64).
    8 GB of RAM.
    Intel Corporation Sandy Bridge Integrated Graphics Controller (rev 09)
    A 2 TB hard-disk.
    A 19״ LCD Screen by ViewSonic.
    Intel Corporation Cougar Point High Definition Audio Controller.
    Intel Corporation 82579V Gigabit Network Connection.

I found another way to reproduce it. After I install empathy (which also installs gstreamer0.10-gstclutter-1.6.0-1.mga3.x86_64 ), then double clicking the Pidgin icon on the KDE desktop causes the X server to crash.

Hi,

I am still experiencing many frequent crashes and would appreciate if someone can investigate this issue and recommend a fix. Please let me know if you need anything else.

Regards,

I should note that this happens only if I put «export LIBGL_ALWAYS_INDIRECT=1» inside my .Xclients file, but I've ran into other frequent crashes with running X apps from an ssh sesssion, so this should be fixed.

We generally don't work on bugs involving indirect rendering (the long-term plan is to render locally and ship images over the wire).
Comment 5 Kenneth Graunke 2017-09-14 22:13:08 UTC 
Sorry we never looked at this.  The X server has disabled indirect rendering by default these days, for security reasons, and a lot of things have changed in the last 5 years.  Feel free to reopen if this is still a problem.
