The new Win10 update to 1903 broke this app #100
Comments
It worked for me after deleting the registry keys also |
In my case, the first restart, it works. Then it breaks after second restart, I have to delete the registry keys again |
After installing Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4503293) |
I have the Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4503293) and it's not fixed for me :-/ |
@scarystuff my LightBulb and Windows Night Mode stopped working today. So the issue is windows update itself, the problem still persists |
Broken on 1903 for me too. |
Not sure if anyone else is still having issues, but I had it not work once after a reset. I just deleted the 2 registry files again and it seems to be working as intended now after resetting multiple times. This is on the Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4503293). |
@Win10pissesmeoff I deleted the registry keys, but after restarting, the problem comes back. |
The problem comes back for me if I shut down my PC but I usually just keep it on sleep so that's why it wasn't resetting for me. Not sure how to fix other than deleting the registry files after every shut down. |
Finally it's fixed |
Still not fixed after installing kb4501375 for me. |
I can confirm it's still working for me after many times restarting. |
Not working for me either on the latest cumulative update (KB4507453). |
Enabling or disabling multi-monitor in Windows fixes the problem temporarily until next scheduled color shift. |
I just tested, and this is true for me as well. Updating to the latest (KB4507453) made no difference, but Lightbulb immediately began working once I disconnected all but my primary monitor. @Tyrrrz, it appears the issue with color temperature not changing is caused by multiple displays, ever since Windows 1903. |
+1 same issue, disabling multi-monitor fixes it. |
Looks like Windows broke something with this update. The fact that it affects only multi-monitor setup leads me to think they changed something related to how the I'll try to figure out if there's a workaround as soon as I have some time. |
Any news on this front? |
Working on it. Making some large changes in #105 which should hopefully enable tackling this issue. |
|
Unfortunately, does not work on multi-monitor setup. At least works when only single monitor is used. Previous version did not work for single or multi monitor setup. |
@Dainius14 just to clarify, "does not work on multi-monitor setup" means that neither of the two monitors' gamma change? or does it mean only primary monitor is affected but the other monitors stay the same? |
I think it means both, I briefly tested it a few days ago and couldnt notice any change |
None of the monitors work

Tried it now. Does not work :( Nothing happens on multi-monitor setup |
I used the portable version(not installer) |
@Dainius14 try this one https://github.com/Tyrrrz/LightBulb/commit/9018e191f2c36c501566ad111c8ca64c3cc9d2e7/checks?check_suite_id=305727114 |
Great work! It's working! |
Sweet :) |
@Dainius14 Did you use the portable or installer? Portable for me is still not starting. |
Fix is in master, build is here, please test this on both single monitor and multi-monitor setups. And if you have access to Win7, Win8, Win8.1, it would be nice to test on them too. CC @mirh @NomDeMorte @aure2006 if you guys can help test the latest build. @starsoccer |
Also, @starsoccer you might need to install .NET Core 3.0 runtime (installer sets it up automatically). |
Giving it a try now, but I dont think thats the issue. Mainly because my other portable install, 1.6.4.1 starts fine. So unless this is a new requirement I dont think its related. |
Yes, it's new in 2.0 |
Nice that worked, would be useful to have that as an error popup. Like if its not found to show an error saying both are needed |
I will include a notice on release page when 2.0 is released |
Seems to be working here, on both monitors - although I'm still on 1809 so I'm not sure if this is of any relevance.... at least, the change didn't break old versions ;) |
I couldn't get this to work on 1903. I just updated to 1909 and it still doesn't seem to be working on either monitor. Windows night light doesn't seem to do anything either. |
@spacecheese what interface are your monitors connected with? Does f.lux not work either? |
@Tyrrrz my monitors are connected to a gtx 970, f.lux seems to work fine though I'll try an update my graphics drivers and see if that makes any difference. |
I've also updated to 1909 today and there is no change in LightBulb functionality (or f.lux). |
New drivers didn't seem to make any difference. |
@spacecheese I mean, are you using DisplayLink dock connect by any chance? |
@Tyrrrz not using anything like that. My monitors are directly connected to the graphics card outputs. |
Appologies. I've resolved my issue- it seems that the display drivers that TeamViewer installs don't support gamma ramps so that SetDeviceGammaRamp was failing. |
@spacecheese |
Teamviewer has an optional monitor driver that replaces the Windows "Generic PnP" one so that you can draw pictures over the screen. Pretty annoying to track down. |
Good to know. We should probably have a list of known issues like this. Edit: apparently there already was a wiki page from 2017 lol. https://github.com/Tyrrrz/LightBulb/wiki/Troubleshooting |
FWIW, I do occasionally use a MS Teams conferencing project, can't recall if it is called TeamViewer, but that sounds familiar. I don't install the full version - just the one-time download when joining a meeting. I can't tell if it has mucked with my driver or not. Or if f.lux would be similarly affected by that? On a separate note, I've also confirmed that I do not have a DisplayLink driver installed (as described in the link from the Troubleshooting page). That's what I would expect since I'm using DVI via my dock, but thought I'd double-check. |
@ChrisLMerrill I think your situation is a bit different. Also, I have MS Teams installed on my other PC and it works fine with LightBulb, so I don't think it's related to that. You could however open device manager (Windows key + type "device manager" + press enter) and check what it says under "Display adapters". |
Under display adapters, it lists AMD Radeon M370 and Intel HD Graphics 530, which is correct for my Dell E5570. Under Monitors, it shows Dell U2410 (twice for my dual monitors) and Generic PnP Monitor, which I assume is my built-in display (inactive at the moment). |
@ChrisLMerrill let's continue discussion in #102, I left a comment. |
Never had any issues before but after this Windows 10 update to 1903 this app doesn't work at all anymore. Not sure if there is an setting to fix this but figured you'd want to know about it.
Edit- After doing a bit more searching I found a fix on this page https://answers.microsoft.com/en-us/windows/forum/all/windows-10-1903-may-update-breaks-night-light/75f21187-07ff-4c3d-b552-f390f205db67?auth=1
I had slightly different files other than what was listed but I found 2 by ctrl+F "windows.data.bluelightreduction" and deleted that one and "windows.data.bluelightreduction.settings"
I restarted and it seems to be working again. Will update if the problem persists.
