Apparently it's a bug in libx11, which persisted for a long time but became much more likely with an update in libxcb.

Just to add a few thoughts, this bug affects Google Chrome also. The error is hard to reproduce, it happens anytime, even if in idle mode. However Chrome seems to do a lot of things in the background. I've put this here just to ask if the bug could be somewhere else, like in the libxcb or libx11 that causes other applications to crash. I upgraded a few days ago from 16.04 and there were no problems. ** Attachment added: "Google Chrome affected by similar error" https://bugs.launchpad.net/ubuntu/+source/pcmanfm/+bug/1782984/+attachment/5317148/+files/2020-01-02-152943_1119x504_scrot.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782984 Title: PCManFM freezes with Assertion `!xcb_xlib_threads_sequence_lost' failed when clicking on a file or folder in 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcmanfm/+bug/1782984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, any news on this? I have the same issue on Ubuntu 18.04.3 LTS. I have upgraded from 16.04 recently and started to have this error. This bug also affects leafpad and probably meld. meld has a fix or workaround but can't remenber what was the fix, i had to install the latest meld from source, that fixed the problem. I would like to hear if someone found any workaround or is it a bug on libX11? https://github.com/mirror/libX11/blob/master/src/xcb_io.c#L259 Looks like google chrome freezes from time to time in a very similar way but could be a tone of things, just for the record.

Actually, Daniel, your mention of "upgrading" to LXQt has me wondering whether or not you took an LXDE version and then upgraded to an LXQt version(unsupported by Lubuntu, officially) without cleaning up all the old LXDE/GTK stuff. This could certainly lead to you using pcmanfm rather than pcmanfm-qt or otherwise using some app or apps that use GTK2, which everything seems to point to being the problem. LXQt doesn't use GTK-anything, so it should entirely be a non-issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782984 Title: PCManFM freezes with Assertion `!xcb_xlib_threads_sequence_lost' failed when clicking on a file or folder in 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcmanfm/+bug/1782984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi All, This problem still exists in LXDE - after reading the comments here I upgraded to LXQT and I am still experiencing the same problem. This seems like it is something endemic to this desktop environment and I would also agree that it seems to come about from "Clicking too much". Basically Lubuntu is unusable as is which is a huge shame - especially as LXQT is really sleek for my uses. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782984 Title: PCManFM freezes with Assertion `!xcb_xlib_threads_sequence_lost' failed when clicking on a file or folder in 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcmanfm/+bug/1782984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1782984] Re: PCManFM freezes with Assertion `!xcb_xlib_threads_sequence_lost' failed when clicking on a file or folder in 18.04
This bug still exists. PCManFM randomly freezes and prompts me to end the process. Like @Patrick Schmitt, I receive a "Sorry Ubuntu has experienced an internal error " message, and when I than try to see the details of the error message, the message window itself crashes instantly. In addition to this, the desktop icons will disappear, leaving just my wallpaper. I can't get my icons to reappear unless I restart my computer. Today, matters got worse. Now when PCManFM freezes and its process ends, my desktop completely resets to its default state. I see the default Lubuntu wallpaper and all my icons lose the places I moved them to and shift to the left side of the screen. The font size and color reset to the default too. It's been over a year since this issue started. This is getting ridiculous. I'm a new user to Linux and I have to face an issue like this within months of picking up this distro. Developers, I hope you realize this is a very bad look for you. Windows would have fixed a bug like this within a day. I thought LTS was supposed to be the stable version? Can someone please tell me how to solve this?

This is (maybe) the solution, especially for small size RAM... under 2GB... When i change and set the thumbnail_size in ~/.config/libfm/libfm.conf as 320 from 512 (default), then there is not any random crash anymore... You may to change as an even lower number (till 64)... Or if you prefer GUI, you may change the value from pcmanfm/preferences/display/value_of_thumbnails. In every case, you must restart pcmanfm after value changing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782984 Title: PCManFM freezes with Assertion `!xcb_xlib_threads_sequence_lost' failed when clicking on a file or folder in 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcmanfm/+bug/1782984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
