Any changes recently?

Comment 3 Robert de Rooy 2009-10-28 09:14:18 UTC
I am seeing the same problem on a ThinkPad T60 running F12 beta. But only when a secondary display is attached (multi-head).

I tried upgrading to the latest Intel driver, Xorg and kernel to no avail. Here are my current versions;

If I use that same kernel version on a plain F11 install, multi-head works great.

Comment 5 Vedran Miletić 2009-10-28 15:57:57 UTC
Original bug is G31, and you have 945GM. Not sure how similar these are, but let's leave it as 945GM for the time being. Updating summary.

Comment 6 Matěj Cepl 2009-11-05 17:14:38 UTC
Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages (at least F12Beta, but even better if the very latest versions).

Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.

If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.

Comment 7 Robert de Rooy 2009-11-05 18:04:29 UTC
Yes this segfault is a current issue, and is preventing me from upgrading my work system to F12.

Comment 8 Søren Sandmann Pedersen 2009-11-05 19:19:42 UTC
You may want to try xorg-x11-server 1.7.1-5 or later.

There is a good chance this bug is fixed there.

Comment 9 Robert de Rooy 2009-11-06 07:26:45 UTC
Indeed, I upgraded to the latest 1.7.1-6 build and it works again. For me this issue is therefore resolved.

Thanks for reporting back.
