[Bug 1090480] New: OpenSUSE Leap 15 redshift causes screen flicker on KDE
http://bugzilla.opensuse.org/show_bug.cgi?id=1090480 Bug ID: 1090480 Summary: OpenSUSE Leap 15 redshift causes screen flicker on KDE Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Normal Priority: P5 - None Component: KDE Applications Assignee: opensuse-kde-bugs@opensuse.org Reporter: mobile.harvey@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Comparing two identical deployments of Tumbleweed and Leap 15 Beta with KDE desktop. On each I have installed Redshift and added the Redshift widget to my panel. On Tumbleweed I see the expected behaviour whereby enabling the redshift widget enables Redshift, and vice versa. On Leap 15 however Redshift seems to be already running on boot, and enabling the widget ends up with two instances seemingly running together. The result is the screen will switch between cold and warm white balances every 1-2 seconds. Disabling the widget stops the flickering but Redshift still seems to be running (i.e. my screen changes to warm white balance in the evening). Below are some observations which I believe sum-up the delta between Leap 15 and Tumbleweed. Can Leap 15 be made to work like Tumbleweed?

AFAICS there is no difference between the current packages in Leap 15 and Tumbleweed though, they appear to be exactly the same. One thought though: do you have plasmoid-redshift installed on the affected system? (from KDE:Extra e.g.) That does contain an autostart file that may run redshift on login to a KDE session. If yes, uninstall it, it's a plasmoid for a KDE4 desktop and won't work with Plasma5. And what "Redshift widget" exactly are you talking about? How do you add that to your panel? -- You are receiving this mail because: You are on the CC list for the bug.

I can fix this by modifying the upstream systemd unit to no longer start by default. For now, you can simply disable systemd redshift: systemctl --user disable redshift.service What I do not understand is if something is really different between Leap and Tumbleweed. Redshift has been in Factory with the upstream systemd user unit for 4 months and package contents should be the same. Can you provide specific package versions on each system? i.e. rpm -q --queryformat="%{NAME}-%{VERSION}-%{RELEASE} %{DISTURL}\n" redshift and for good measure double-check the systemd unit vendor preset and enabled state on both systems: systemctl --user status redshift -- You are receiving this mail because: You are on the CC list for the bug.

The fix for this particular issue (default status of user services) is actually in the systemd package itself, see https://build.opensuse.org/request/show/610240 which is in Factory/Tumbleweed but will have missed getting into the released Leap 15.0. I am not sure if an online update is planned/necessary, perhaps Franck can answer that. Until then, the fix is to ensure the user service is disabled while the plasma widget is running, as you already spotted. systemctl --global disable redshift.service systemctl --user disable redshift.service -- You are receiving this mail because: You are on the CC list for the bug.

Franck has confirmed the update for systemd will be released for Leap 15.0. Once that is out, a reinstall (or any new installs) of redshift will start disabled. The plasma widget you have installed runs its own instance of redshift. Therefore (user AND global) systemd redshift services should be disabled when the widget is installed. Try restarting once the services are disabled and then check the widget functionality. If the widget is now failing to start redshift, that may be a different bug; it was working as of your original report. -- You are receiving this mail because: You are on the CC list for the bug.

Slight confusion on my part about the commands and whether to run as sudo or not. Here's what I did to get this to work: sudo systemctl --global disable redshift.service #running without sudo stated permission denied sudo systemctl --user disable redshift.service Failed to connect to bus: No such file or directory Disabling the user service without sudo just returned nothing. Not to worry as I've rebooted and the redshift widget not only switches on and off correctly, but when on it no longer flickers. That'll do me for now and I'll re-install redshift when the systemd update arrives to test the final fix.

Just for clarification, I said that it will be certainly part of an *update* release. AFAIK Leap 15.0 is already released. -- You are receiving this mail because: You are on the CC list for the bug.
