If it's software at all then this would be a kernel bug. But I suspect the issue is more likely hardware since 1920x1080 @60Hz is pushing the limits of analog VGA. Anything less than a perfect cable with perfect connections and I'd expect display glitches like this.
Personally I'd recommend adding a graphics card to the machine so you can use HDMI on both monitors. But you might also want to try 30Hz to see if it makes the display more stable. We can also keep this open as a kernel bug just in case it is. ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Summary changed: - multiscreen one display goes black on resume + Analog VGA goes black on resume -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2049976 Title: Analog VGA goes black on resume Status in linux package in Ubuntu: New Bug description: Starting a few weeks ago after applying regular maintenance to 22.04.3 LTS one of my two displays, an LG 22MP47HQ-P connected to my tower by a D-Sub cable, blinked multiple times immediately on resume from suspend. My second display which is connected using HDMI works normally. This, of course, was merely a mild annoyance because after a few seconds it stopped. However in the past week that same display flashes on, and then goes black. I power the display off and back on and again it flashes on for a fraction of a second and then goes black. After several power cycles of the display it stays on, so again this is only a mild annoyance. Is this a known issue with a recent update? Specifically this is after a deep suspend, one where on unlock you need to press a key to get the login prompt. I tried updating to 23.10 but the problem is there as well. This bug tool does not permit reporting a problem against Wayland. lshw -C video *-display description: VGA compatible controller product: Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics
