Hmm, my stack looks pretty much like the one in https://bugs.launchpad.net/bugs/539772. But after installing xorg-server - 2:1.7.6-2ubuntu7.1, which is supposed to fix #539772 I can still easily reproduce the crash. Either I'm seeing a different problem here or the fix does not work. Not marking as a duplicate yet. More investigations required.

ooops, please ignore my previous comment. I had a package pin left over from my investigations and not all packages were updated now. So there are still chances that the correction actually works. It's too late now, I'll investigate this tomorrow. -- [RV250] Kubuntu Lucid: Xorg gets SEGV https://bugs.launchpad.net/bugs/575140 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Bryce, [This is an automatic notification.] This bug was reported against an earlier version of Ubuntu, can you test if it still occurs on Lucid? Did your script fail here?

[Bug 575140] Re: [RV250] Kubuntu Lucid: Xorg gets SEGV
I was somehow guessing that EXA could be the culprit and tried to verify my guess by disabling EXA. How could I do that? Simply renaming /usr/lib/xorg/modules/libexa.so did not work, the server gets a fatal error when it cannot locate the file. I googled around and understood that XAA is a predecessor of EXA. So I created the following conf file: Section Device Identifier Configured Video Device Driver ati Option AccelMethod XAA EndSection According the log the file was read without warnings and AccelMethod XAA was selected. But the Radeon driver still decided to load libexa.so. And no surprise the crash did occur again. Is EXA hardcoded in the drivers for this card or can I disable it somehow? -- [RV250] Kubuntu Lucid: Xorg gets SEGV https://bugs.launchpad.net/bugs/575140 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
