Hello,
im a new linux user, having a little experience with ubuntu but very new to manjaro.
I just installed manjaro with XFCE and noticed that im having a black flickering from time to time. Usually after booting it occurs some times. When using the system it occurs unregularly. It sometimes happens 3 times in a row, and sometimes doesn’t occur for 10 minutes.
I dont really know how to describe the problem… it looks like the screen is turning black for a split second.
My primary screen is a 144hz screen (2560x1440, DisplayPort) and it feels like the problem doesnt occur when i set it to 60hz.
I have a secondary screen connected (1920x1080, HDMI).
On installation i selected to use NVIDIA drivers.
In NVIDIA X Server Settings i tried selecting “Force Composition Pipeline” or “Force Full Composition Pipeline”, but after that it doesn’t look and feel like it is 144hz.
When I select “Save to X Configuration File” and then select “Show Preview…” it shows this:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 460.39

[ 993.822] (EE) event20 - HID 046a:0023: client bug: event processing lagging behind by 12ms, your system is too slow
But this doesn’t seem to be the problem. I tried to convert the timestamp with date -d “-458.747 seconds” and this is no time when there was a flickering.
Id be very thankful if someone could help me here.
