Fglrx 12.6 segfaults at startx (Radeon 7950, Gentoo Hardened)


Just bought a new computer, with a Radeon 7950 videocard. I installed ati-drivers-12.6, and run aticonfig --initial.
However when i execute 'startx', i get a segfault:

As the topicsubject suggests, i run Gentoo Hardened. I have heard of problems between Hardened and Fglrx, however these were quite old. As this is the first time i run Gentoo Hardened, so i don't have experience of Hardened in combination with Fglrx.

The word that jumped out of that to me was 'Hardened' as in Gentoo Hardened.

This is where you want to investigate that hardening process. The only hardened system I ever ran was hlfs, and it used pax/grsecurity. There was a little utility called paxctl that allowed you to bend rules. You need to learn your own system. I also imagine Gentoo will have some advice.

I disabled PaX/GRsecurity in my kernel, and all PaX flags should be disabled:
Code:
# paxctl -v /usr/bin/Xorg
Pax control v0.7
Copyright 2004, 2005, 2006, 2007, 2009, 2010, 2011, 2012 Pax Team <pageexec@freemail.hu>

- Pax flags: -------x-e-- [/usr/bin/Xorg]
        RANDEXEC is disabled
        EMUTRAMP is disabled
I have found forums with similar segfault posts, however the solutions didn't work for me.
I think i will test a non-hardened Gentoo installation this evening.

It's 10 years since I was near that stuff, but disabling it in the kernel may not be enough. The system is put together differently, which is why a lfs approach to a hardened system is always better. There is/was a very good explanation of the differences in the early part of the HLFS book.

Hmm interesting stuff. Never heard of Hardened LFS before. I will check it out sometime.

Use the Catalyst 12.7 Beta driver. If that doesn't work well for you, you need to use an older version of xorg.

I'm running Debian Wheezy and the way I fixed it originally was to use an older Xorg version that I pulled from Debian Squeeze and grabbed catalyst 12.6 to go with it as well.

I believe now the 12.7 Beta will work with the newer versions of xorg that you're trying to use now, but I'm too lazy to try it. Good luck.

The joys of running bleeding edge hardware... Ya' know?

I reiinstalled Gentoo (not Hardened this time), the Xorg and driver versions are the same as before. Now it runs without a problem.

I think you can mark this solved, then.

You really only want a hardened system if you expect hacking attempts. They do best for servers where some program is compromised by a hack attempt and the hacker will find it difficult and noisy to get out by comparison with the ordinary user. For home boxes, hardening is just a pain.
