 Posted: Mon Jan 25, 2021 12:15 pm Post subject: cinnamon-4.8 crash at startup |
 |
|
I've installed the new cinnamon-4.8 and the session crashes at startup. I've tried to start openbox as fresh new user and use | Code: | | cinnamon --replace >~/cinnamon.log 2>&1 |
from tmux. Below is the only entries I've got:
| Code: | Cjs-Message: 12:59:34.581: Profiler is disabled. Not setting up signals.
Clutter-Message: 12:59:34.597: Sync method: PRESENTATION TIME
Gdk-Message: 12:59:34.614: cinnamon: Fatal IO error 0 (Success) on X server :1. |
The following packages have been updated: | Code: | x11-libs/xapps
gnome-extra/cinnamon-menus
gnome-extra/cjs
x11-wm/muffin
gnome-extra/cinnamon-control-center
gnome-extra/cinnamon-screensaver
gnome-extra/cinnamon-session
gnome-extra/cinnamon-settings-daemon
gnome-extra/nemo
gnome-extra/cinnamon |
cinnamon-4.6.x works on the same box without any issues. I'd appreciate any help! |

Is there something related to the crash in syslog?

I haven't been able to find any other traces of this crash while running 'cinnamon --replace'. However if I start cinnamon directly form ~/.xinitrc (exec /usr/bin/cinnamon) the following entry in the log appears: | Code: | | kernel: traps: cinnamon[2207300] general protection fault ip:7ff9437b0450 sp:7ffc16f7bc50 error:0 in libcjs.so.0.0.0[7ff94377d000+82000] |

Looks similar to an old bug, fixed by patching libcjs.
Try to downgrade gnome-extra/cjs?
Or, it was recommended in the same bugreport, to disable the network data monitor.

Thanks for the tip! I've tried both cjs-4.8.0 and 4.8.1, but the error was the same, then I tried the old one 4.6.0 (which is obviously incompatible) and I've been able to see "desktop", but no applets at all.

I'm not sure what exactly this means, but removing /usr/share/cinnamon/applets/network@cinnamon.org didn't change anything. |

CJS is Cinnamon's Javascript interpreter. If I decide to debug that issue, I would try to disable all the applets (by one or in groups; it can be done in menu), and/or to insert "log/Global.logError" lines into applet.js files of the active applets (non-active applets should not affect the situation at all) to see where the code runs before the segfault and where not.

yeah, I've tried removing ALL the applets in /usr/share/cinnamon/applets already but the error is still the same. I think the error occurs earlier in one of the scripts in /usr/share/cinnamon/js/ui... |

Hmm... I am not an expert in Cinnamon and in DEs in general, I just help to a friend to configure it on a laptop, and I do it mostly via menu  When you untick an applet via menu, does its folder disappear from /usr/share/cinnamon/applets? If not (as I guess), then those operations are not equal, and the decision to go to the folder or not to go can be taken right in /usr/share/cinnamon/js/ui; if you removed the folder for an applet that is still active in menu, it could be an exception for ui.
If the problem is in js/ui, then I would try to insert logging lines in its scripts, beginning from js/ui/main.js (where is written "This is the heart of Cinnamon"), from the function 'start' (where variables needed for logging are declared).

I do appreciate you help very much, thanks for your time! I'll try to dig into this issue. |

Not at all! If you have questions about JavaScript syntax, feel free to ask, I have some experience in it.

If I start with a fresh new user profile I see the following suspicious error in the log file. | Code: | Cjs-Message: 17:51:41.359: Profiler is disabled. Not setting up signals.
Cinnamon warning: Failed to load theme "Adwaita": Failed to find a valid file for theme Adwaita

The theme is installed and I can select this theme if I run cinnamon-settings form openbox... |

There's a tutorial how to report cjs crashes at https://github.com/linuxmint/cjs/tree/b69b7477705481c50b9373acba0d5832076ca18b , among other things it lets to determine the name of a function where the crash happened.

Good catch  I don't use sysprof, but just in case tried to compile cjs with sysprof use flag which enables profiler, but unfortunately this didn't solve my problem as well. I'm really curious what is going on, but this takes too much time already. Maybe it's a time to stick to amd64? |

I saw this one in the bug report as well and the result is: | Code: | addr2line -e /usr/lib64/libcjs.so.0.0.0 33450 -fCi
??
??:0 |
I think I'm missing some debug symbols... |
