OM crashes systematically on Ubuntu 21.10

#45

Will try with that two options checked, then.

I don’t think that the problem is workspace related because I have tested with different ones and the crashes were persistent across them.

But I send attached the one I’m working on currently.

I have been using Ubuntu 20.04 until last week when I did a fresh install of Ubuntu 22.04. Just after upgrading, I installed OM and the problem begun to show up. I don’t think I customized anything in Ubuntu since then… The only thing I did was to change from Wayland to Xorg windowing system from the login screen’s cog, but when I did that I had already experienced the crashes.

Thank you, Karim!

#46

Just to add that the crashes keep happening after checking Handle Error and Enable Evaluation only on General Preferences.

#47

Sorry for the overposting, but I just want to add also that the popup with an error message continues to show up on the initialization of OM 7.1. The message is: “ERROR: In 1- of (nil) arguments should be of type number.” I can just close the popup and continue using OM normally, yet maybe it refers somehow to the crashes, I don’t know…

#48

Ok Paulo,

Thanks for reporting back. I will try to see what’s wrong here. It could be the new veraion of gnome and its lib. I will send your crash report to LW team. It could be LW related.

Thank you, Karim. Please let me know if you find something… In the meantime, I’m trying to work piece-by-piece between crashes. Will also consider installing another distro, perhaps Ubuntu is the problem.

By the way, always with hope that a new info can help clarify what the problem could be, I’ve noticed a new message on Terminal when the last crashes happened (OM 6.2, this time):

[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
openmusic: ../../src/xcb_io.c:175: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.

All best,
Paulo

Hi Paulo.

Will also consider installing another distro, perhaps Ubuntu is the problem.

Perhaps i could suggest testing with Fedora? It could help narrowing in since I develop code on Fedora, and i beleive Karims main platform is Ubuntu. (No, Karim?)

No i use mainly Debian. (Ubuntu is a Debian based distro). But i am afraid it is not due to a distro, but maybe to GNome. However, teste it on fedora and it works also.
Did you have an issue on Fedora?

Hi Karim and @anders

I just changed the window system to KDE-Plasma yet on Ubuntu 22.04 LTS. The crashes continue to happen, unfortunately.

Anders, I will maybe try first to run OM through a live Fedora flash drive - I don’t know if it’s possible to run Fedora like this, as we do with Ubuntu.

I’ll let you know what happen then.

Thanks!

Hi,

It should be possible to run Fedora from a live usb flash, I have used this method, time ago, to verify new versions before installing them. Perhaps here some useful information:

Dear Paulo,

Before getting into installing another distrib, can you just try running OM in a different window manager, such as xfce4. You can install it on your ubuntu then reboot, and choose this WM. Maybe things will get better. I suspect something that has to do with Gnome WM.

Dear Karim

Yes, as I said one or two days ago, I’ve changed it to KDE Plasma and the problem persists. Will try xfce4 in the next days, then.

Thank you!

#56

Yes I have read this. Both KDE plasma and Gnome are heavy weight window managers. That is why i am proposing to try with xfce in order to see where the problem lies, since i cannot reproduce your problem and i don;t know if it comes from your installation or indeed a bug in LW/OM.

Dear Paulo,

Ok, Finally succeded into getting your problem so no need to install whatever. However here, OM freezes instead of crash. I suspect something to do with your patches. I will investigate.

Dear Karim

Ok, thank you very much for the help!

Maybe it’s important for you to know that I am probably using the wrong terminology all this time: my OM freezes and I am asked to “Force Quit”. It doesn’t crash instantaneously.

Also maybe is important to tell you that OM froze the entire system once or twice among these errors.

Finally, I would like to report that I am using the same patches without error on another machine (at my University department) on Windows 11. No freezes (or crashes or whatever). Also, I’ve experienced OM freezing with other patches too, besides that one I’ve sent.

Hope to hear from you soon! Thanks!

#59

Dear Paulo,

Thanx for reporting this. I think it might be a combination of new libraries in gtk, and more. Can you just test this: Create new patches and start working with them to see if it happens. I noticed that moving around the boxes in old patches are very slow, but not when you create a new one. I don’t know if it is a virtual machine issue or not. Just to be sure,

Dear Karim

I believe that now I have done tests enough to confirm to you that the freezing doesn’t happen on a fresh patch with no copy-and-paste objects from old patches saved on past workspaces or tutorials and stuff.

Will try now to mess around this new workspace creating patches with copied objects from former projects… then with imported patches from old workspaces to see if OM start freezing again.

I’ll let you know.

In the meantime, assuming that the problem really is the combination of OM old patches (or objects) and Ubuntu 22.04, do you think there would be a workaround? Or I will probably be better starting works on OM from point zero from now on? (at least while using Ubuntu…)

Thank you very much! I really appreciate all the attention given to this, so far.

Paulo

#61

Dear Paulo,

I am afraid that this is not the real issue ie old/new patches. I think i know what’s wrong. I am working on it. In fact this “bug” was introduced when porting OM from LW7 to LW8.
I will keep you informed.

Thanx again for reporting.

Dear Karim

Just to add that I am able to use OM 7.1 without freezings or crashes on a Fedora 36 Virtual Machine - using either old or fresh patches and objects.

Ah, and I would just like to remember that OM 6.2 (LW7 based, correct?) also freezes on my Ubuntu 22.04.

Thank you again!

#63

Dear Paulo,

Do you mean OM 6.20 i believe no?
If it is so, yes it is base on LW7.

THanx for reporting.
Will keep this in mind.

Yes, I meant OM 6.20 indeed.
