Bug Description

Booting from Ubuntu 9.04 Live CD I get the following warning message in .xsession-errors file:

I/O warning : failed to load external entity "/home/ubuntu/.compiz/session/1043119e9cf87de33f123725997285809400000049470017"

I see this error message in my .xsession-errors file (ubuntu 10.04):

I/O warning : failed to load external entity "/home/user/.compiz/session/10d25c55e671baf78d127419533628510600000015610032"

This is really not a problem. It just means you didn't save your session.

if it is not a problem then the warning message should not be displayed

How can a fresh session be generated then. Or all sessions wiped out so a fresh one can be created? I am getting this also.

I get this warning too, which might not be much of a problem at all, but I would still like to address it.

Firstly the error msg in .xsession-errors adds difficulty of troubleshooting, secondly I suspect that the error msg indicates
gnome will first try to recover the saved compiz session, find no saved and output the error msg, then start a new one.
Obviously this slows down the loading speed of gnome desktop when logging in.

I have the same message in my ~/.xsession-errors file under Ubuntu 10.10 Netbook Edition on ASUS EeePC 900:

I/O warning : failed to load external entity "/home/val/.compiz/session/<filen>".

Compiz works. But I want to delete this warning. On my desktop with Ubuntu 10.10 compiz has similar configuration and installed from the same source. And there is no such warning in ~/.xsession-errors.

I find workaround. if disable Session Management plugin in Compiz Config settings Manager and logout/login then the message disappeared. But it is not the solution, because on my desktop with the same configuration (only OS Ubuntu 10.10 rather than Ubuntu 10.10 Netbook Edition) there is no such message.

May be Ubuntu Netbook Edition doesn't use gnome-session so Session Management in CCSM doesn't work (http://otvety.google.ru/otvety/thread?tid=5c2806c977ec6253)?

After every reboot file name in the warning "/home/val/.compiz/session/<filename>" is different.

I tried to save session via System - Preferences - Startup Applications - button "Remember Currently Running Applications". I also tried to reset compis settings by CCSM - Preferences - button "Reset to Defaults". After reboot the warning still appeares.

I tried to delete file ~/.xsession-errors. But after reboot it creates again with the same warning.

The problem solved by deleting Compiz Fusion from System - Preferences - Startup Applications. On my desktop Compiz Fusion didn't exist in System - Preferences - Startup Applications.

I get this error message in 11.04 beta, accompanied by the following, which may or may not be related:

Sometimes, ~20% of the time, when an application gains focus, or is maximized, the window displays is blank and white. The window does not display application content until some combination of minimizing, maximizing, changing focus, or restarting the application is performed. The exact sequence seems to vary.

I hit the same problem after "ubuntu" (unity-3d) profile was BROKEN here.
To workaround this, I used "unity-2d".

compiz-session-ids are stored at different places.
unity-2d: ~/.compiz/session/
ubuntu (unity-3d): ~/.compiz-1/session/

When switching at the X-login-manager (LightDM) from "unity-2d" to "ubuntu" (unity-3d) you will hit the warning.
NOTE: ~/.compiz/ dir gets removed.

The profiles in LightDM are called "Ubuntu" and "Ubuntu-2d".

NOTE: Check ~/.dmrc file!

Ok, I'm still getting this warning on Ubuntu 13.04 fully updated:

I/O warning : failed to load external entity "/home/darkhole/.compiz/session/10feb45e4f48274a12136340188589842900000018690036"

This bug is back in 15.4 64-bit. At least it is back if you try to auto-start a gui application from a .desktop file.

I've seen this in 16.04 today (kernel 4.8):

can you reproduce this in Ubuntu 16.10?

@petrosyan I'm still on fully up-to-date 16.04, Kernel 4.8 via HES packages.

I've just seen this again in syslog:

gnome-session[3496]: I/O warning : failed to load external entity "/home/userX/.compiz/session/106261e716d9321ea1149497258226461600000034960003"

This time, my whole gnome session crashed after this error occured.

I was left with the login box, after that all desktop applications were closed. That implies data loss of unsaved data in applications that were open before the crash.
