mythfrontend segault in libGL

[tmorley]

Binary package hint: mythtv

Just done a apt-get dist-upgrade, rebooted and mythfrontend doesn't start.

Using the nouveau x-server.

Here is the backtrace from the core file.

Can you please make sure you have *no* remenants of the closed source
nvidia driver?

dpkg -l | grep nvidia

Should be sufficient.

I have the following installed:

rewind@rewind:~$ dpkg -l | grep -i nvidia
ii nvidia-173-modaliases 173.14.16-0ubuntu1 Modaliases for the NVIDIA binary X.Org drive
ii nvidia-180-modaliases 180.44-0ubuntu1 Modaliases for the NVIDIA binary X.Org drive
ii nvidia-71-modaliases 71.86.08-0ubuntu1 Modaliases for the NVIDIA binary X.Org drive
ii nvidia-96-modaliases 96.43.10-0ubuntu1 Modaliases for the NVIDIA binary X.Org drive
ii nvidia-common 0.2.9 Find obsolete NVIDIA drivers

Trying to remove them fails, as mythbuntu-common depends on nvidia-common which, in turn, seems to depend on the nvidia-*-modaliases

[Mario Limonciello (superm1)]

Those are okay to have, not a worry.

FYI, I see this mythfrontend crash as well, since upgrading packages a couple days ago.

I'm on Jaunty amd64, using open-source radeonhd driver (latest from git.)

[shuvalov (shuvalovpavel)]

i think it is not mythtv bug, but don`t know exctly what package it affect. Maybe qt4-x11?

[brian.hasselbeck (brian-hasselbeck)]

It seems this bug was introduced with the mesa 7.4 update: libgl1-mesa-glx (7.4-0ubuntu1). Downgrading this package to the previous 7.3-1ubuntu4 version solved the problem for me.

(I grabbed the old version of the package from here: https://launchpad.net/ubuntu/jaunty/amd64/libgl1-mesa-glx/7.3-1ubuntu4 )

[shuvalov (shuvalovpavel)]

Hm, i am found one similar bug in qt-x11 (dated 2009-04-07): https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/356940/

[Jonathan Thomas (echidnaman)]

Mythtv is a Qt3 application, so it's probably not a Qt4 bug.

[Greg Helps (bigdoggy)]

mythfrontend also segfaults for me with a SIGSEGV in QGLWidget::resizeEvent() on an updated jaunty i386 install.

Downgrading libgl1-mesa-glx to 7.3-1ubuntu4 (as posted above) resolves the issue for me.

[Jonathan Thomas (echidnaman)]

Seems to be a mesa problem, so invalidating the mythtv task.

Conversely, confirming the mesa task due to the duplicate bug.
