Bug ID: 396071
Summary: plasma5 screen management going wrong
Product: KScreen
Version: 5.13.2
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: common
Assignee: se...@kde.org
Reporter: bugreporte...@gmail.com
Target Milestone: ---
With the most recent update of KDE, screen management is acting up. I have a
desktop with 3 monitors.
Expected behavior: If no hardware has changed, I should be able to log into KDE
and the layout of everything remains as it was when I last logged out. The
arrangement of the 3 monitors in particular should be the same (left, middle,
right).
Actual behavior: Each time I log in, the arrangement of the 3 monitors has
changed. For example, the middle monitor becomes the left monitor. The desktop
wallpapers get mixed up, and sometimes the panel placement gets mixed up too.
In more detail, here are some things I have observed:
1. I get a popup asking me about laptop display options. I'm on a desktop, not
a laptop. Furthermore, the options presented are confusing. None the selections
I have picked have actually worked, and neither has doing nothing. I do not
want this dialog every time I log in when my attached screens have not changed.
More importantly, I do not want my settings lost on each login.
2. As stated, the arrangement of my screens has changed (e.g., the screen that
should be in the middle is arranged on the left or right, etc.)
3. the primary display may have changed too.
Other settings may be lost or changed too, such as the locations and settings
of my panels. That appears to be a consequence of the screen arrangement being
screwed up.
As far as I can tell, this started with plasmashell 5.13.2. This computer,
running the same hardware with Arch and KDE has worked correctly for the last 2
years until this recent update.
Here are my versions:
Linux 4.17.3-1-ARCH #1 SMP PREEMPT Tue Jun 26 04:42:36 UTC 2018 x86_64
GNU/Linux
plasmashell 5.13.2
dolphin 18.04.2
kate 18.04.2
QMake version 3.1
Using Qt version 5.11.1 in /usr/lib
My monitors are:
left: DELL U3415W
Expected Geometry: 3440x1440+0+0
middle: ELL U3415W
Expected Geometry: 3440x1440+3440+0
right: Acer K272HUL
Expected Geometry: 2560x1440+6880+0
I am in touch with a friend running KDe on a laptop with 2 external monitors
and they are experiencing what sounds like the same issue.
