[Bug 938981] Re: Xorg freeze when starting Firefox
The messages are produced by Apparmor, so its running. Check for the presence of profile abstractions/nvidia and open the profile usr.bin.firefox if the nvidia profile is included #include abstractions/nvidia Apparmor profiles are located in /etc/apparmor.d/ and subdirectories. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/938981 Title: Xorg freeze when starting Firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/938981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 938981] Re: Xorg freeze when starting Firefox
This fix seems to work. Since adapting the Apparmor profile to the ATI grafics card as described above I had no single crash of Firefox nor Gnome neither on FF startup nor on opening links from Thunderbird. Everything is working as its supposed to be. All messages in the syslogs are clean. Seems like this case at least on my machine is solved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/938981 Title: Xorg freeze when starting Firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/938981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 938981] Re: Xorg freeze when starting Firefox
Similar/same problem, except
1) I do not have ati, I have nvidia
2) do not have apparmor, as far as I know
System hangs, sometimes in middle of night, sometimes in middle of day.
The last message in syslog is:
kernel: [13054.112526] type=1503 audit(1349642278.078:46):
operation=open pid=5234 parent=5145

denied_mask=::rw fsuid=1002 ouid=0 name=/dev/nvidiactl
twice; here's another:
kernel: [28822.977516] type=1503 audit(1350612822.928:39): operation=open
pid=4869 parent=4831 profile=/usr/lib/firefox/firefox{,*[^s][^h]}
requested_mask=::rw denied_mask=::rw fsuid=1003 ouid=0 name=/dev/nvidiactl
For the other two crashes, the very last thing in syslog is: NVRM: Xid
(0001:00): 6, PE0001 which comes 8 seconds after the above.
This all started happening a few weeks ago. Running lucid.

[Bug 938981] Re: Xorg freeze when starting Firefox
Ok, bad news. Had a severe crash on firefox today.
Good news: Its the first crash that was reported in the system message log, see
the excerpt at the end.
First segfault in fglrx_dri.so happens at firefox startoff and has no
consequences, firefox still firing up and running.
Second crash rebooted GNOME (or maybe Xorg itsself?)

[Bug 938981] Re: Xorg freeze when starting Firefox
I do have this bug also since some time (ok, some months, maybe over a year). Recently I stumble upon Bug#926906 and Bug#712584, both on Firefox accessing the grafix card and AppArmor blocking the access. Since all my crashed seemed to be preceded by a ratelimit and some audit denies (like the poster above stated) I reasoned, if the bugs are connected in some weird way, lets say AppArmor block firefox from accessing /dev/ati/card0 and the overflow on ratelimit crashes the system ? At least I now adapted my firefox apparmor profile and gave it access to /dev/ati/card0. The audit messages are gone and so is the ratelimit msg. I'll watch the situation and post back, if my crashes are gone. For NVidia the bug was fixed with a new abstraction for apparmor.

Same problem. Started to happen after the (automatic) upgrade to firefox 10, in
my case on February 14.
As the OP, crashes sometimes manifest as Xorg restarts, other times system
freezes completely, showing a black rectangle on top left of the screen. It is
deterministic: it always the third time I open Firefox (tabs do not count)
firefox is 10.0.2+build1-0ubuntu0.10.04.1
fglrx is 2:8.930-0ubuntu1 (package build from ati installer)
ubuntu is 10.04 (32bits)
ATI Radeon HD5450 graphics card
I use 3D design tools like Blender with no problem.

[Bug 938981] Re: Xorg freeze when starting Firefox
This actually also happens when opening links from other programs (e.g. click link in Thunderbird). It doesn't seem to happen within Firefox itself, so possibly to do with the tray animation or redrawing fullscreen? I answered that it happens a couple of times per week, but realistically this happens several times per day - I avoid it by keeping Firefox open for days at a time. I have tried the updated fglrx driver. It appears to fail to install (known bug #873058) but I still end up with: ii fglrx-updates 2:8.911-0ubuntu0.1 However, CCC reports 11.8 and the crashes still occur. Crashes perhaps sometimes manifest as Xorg restarts (as if Ctrl-Alt- Backspace was pressed) - I get both hard lockups (more common) and X restarts under similar circumstances. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/938981 Title: Xorg freeze when starting Firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/938981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
