screensaver (lock) causes the color management to drop profile

[Doug Henry]

When the screen fade kicks in to begin the screen lock process (or sometimes after forced screen lock), the active color profile is somehow reset to the default. Re-enabling the profile via settings will correct the issue. It may have something to do with xorg and the native nvidia drivers, as bringing up nvidia-settings app will cause the same issue. I believe this is a bug with budgie as I don't remember ever experiencing this issue with stock ubuntu (e.g. unity version). Possible this is just a strange side-effect, but its the only other time I have seen this behavior outside of the screensaver fade sequence.

My system info follows, please let me know if I can supply anything else to help locate the issue:

- budgie 17.04 (fully up to date)
- nvidia driver 375.66 (1050 Ti)

Also affects me.

Ubuntu-budgie 17.10 artful
4.13.0-16 Kernel
Budgie 10.4-1ubuntu4

Let me know how I can help track it down.

Additional notes:
I do NOT have an nvidia graphics card, just built-in graphics on haswell.

The 'reset' isn't actually reflected in the color settings window: it still SHOWS that I it is using a custom color profile, but it isn't. If i double-click on the (already selected) profile, colors switch and profile is activated again.

Screen lock (as mentioned in bug description) does not influence it. Turned off lock screen in privacy settings, same thing.

think this is probably related or at least in the same area https://bugs.launchpad.net/ubuntubudgie/+bug/1696625

yes, this sounds exactly like the process that resets the color management
as well.

How odd - when I go into Gnome settings > Color, there seems to be no way to simply add a profile from within the GUI, or to use anything other than the default profile. This seems inconsistent with the help page called "How do I test if color management is working correctly?", which I found via the "Learn More" hyperlink within Gnome Settings > Color. I'll raise a separate bug report for this.

(By the way, I'm using the latest daily build for Ubuntu Budgie 18.04, 32bit.)

Thanks,
Ken.
