I’m having a problem with my two 2k external monitors where they, at seemingly random times, will blink quickly on and off, and then after just a couple more seconds show me that they’re receiving any input on that source anymore. In order to hack a fix for this I’ve found two solutions though Googeling;
- Use xrandr to turn the displays off and on. This will however mess with all the open windows in i3.
- Use xrandr to shift the display position back and forth by one pixel. This will get the displays on again without messing with the windows.
Now - these are by no means a temporary fix. It has now happened 13 times the last 40 minutes and I’m going crazy. Following is a description of my setup:
Laptop: Lenovo ThinkPad T490s
Monitors: LG 27GL850-B, Philips E-line 275E1S
Dock: Lenovo ThinkPad Thunderbolt 3 Dock Gen 2
Qubes version: R4.0
Both monitors are connected to the dock using HDMI cables.
The dock is connected to the laptop using USB-C and into the “Lenovo port”, not the USB-C at the far back. If I connect to that other USB-C port, the laptop will not even boot but is stuck at the Lenovo splash screen where I can choose to enter BIOS etc.
Also; This setup worked perfectly with two HD monitors - troubles started after I switched to 2k.
Also; Plugging one of my 2k monitors directly to my laptop through HDMI works just fine.
I hope someone is able to help me here Thank you all in advance
