Bug ID: 363399
Summary: Display setting doesn't allow change in resolution for
external monitor
Product: KScreen
Version: 5.6.4
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: common
Assignee: se...@kde.org
Reporter: nono31...@gmail.com
My laptop is currently running Archlinux.
I have a few external monitors (one at home and one at work), both at 1080p
compatible.
Until a few months ago, I was able to connect and disconnect my laptop to any
of those monitors and it would directly recognized which monitor it was
connected to.
It would then set the screen resolution for the second screen and show it at
the right position next to my main laptop screen (one is on top of the main
screen, the second being on the left of the main screen).
For a few months now, when I connect my screen, the resolution is set by
default to 1280×720 px. Then I go to the System Settings -> Display and
Monitor, but I don't have a list to choose the resolution.
The settings window only shows current 1280×720px and no drop down menu.
One solution I found was to disconnect and reconnect the screen several times,
both with the settings window open and close until the dropdown menu appears.
Another solution is to edit manually the .local/share/kscreen/ corresponding
file.
For connecting my screens, I am using a mini-display port -> hdmi adapter and
the internal graphical Intel chipset. (I have an NVidia optimus compatible
laptop)
Unfortunately I didn't wrote down the version at which the problem appears
because I thought it would quickly disappear with the following versions.
Reproducible: Always
Steps to Reproduce:
1. Connect an external monitor to my Intel chipset
2. Open the systems settings
3. No drop down menu in the Display settings
Actual Results:
The screen resolution cannot be changed from the System settings and once the
change is done, it is not saved when disconnecting and reconnecting the screen.
Expected Results:
A dropdown menu should be available for me to set the right 1920×1080
resolution and that resolution should be saved and resotred when disconnecting
and reconnecting the screen.
