This is a 6 display card that I setup in an array of monitors of 3 across by 2 down so I have one very big area to work on -- that is I can move any window between the screens and stretch them across multiple screens as well. This is using analog connections to the monitors, i.e. there is no EDID. I have had this setup running on OS 11.4 for years and never upgraded to 12.x because I could never get it to work. However, with 13.1 one it did, even with Linux native drivers so things are certainly getting better as on 11.4 it would only work with Catalyst (the AMD proprietary driver, currently 9.4). However, sometimes, and pretty often, when I stretch a window across two monitors (so far I have only seen it when stretching vertically but I only got it going last night so it's early days) the GUI will suddenly quit and in an instant I'm back on the log in screen. At first I thought it was the Linux driver so I installed AMD's Catalyst and was running on the AMD drivers however exactly the same thing happened so it's a bug in a layer above the hardware drivers I'm presuming. Has anyone heard of this bug or a bug that might be this? I'm not even sure what keywords to look for to search for it or I would have done a more thorough search before asking. Also once it happened without spanning across monitors but just when I pulled a window right to the top of the top screen (with the rest of the window on the same screen) which leads me to suspect it's more something with a monitor boundary issue (probably a negative number issue if I was to hazard to guess on the programming level) than just spanning monitors. I have noticed this is KDE and Gnome however in Gnome only with the window on the same screen as I haven't figured out how to get a window moving between monitors to work on Gnome. I've also noticed that it seems to be far more likely if I move the mouse quickly, although again it's early days so that just might be coincidence. Currently I am only running under KDE even though I am used to Gnome because I couldn't get Gnome to do a span across monitors, at least with native drivers, I haven't tried with the AMD driver. I suspect that's just me not knowing the new Gnome more than anything however. One last symptom, and I noticed this in both Gnome and KDE. If I move a window to some position where it causes this instant jump to the login screen I may not be able to log in after that. I'm assuming this is because a window is in a postion where it's causing the error perpetually. There was one lot of online upgrades that was left when I last observed this particular behavior. Since then I have always been able to log in after being kicked back to the log in screen however I have not done much so that could be only because I haven't done enough to cause that again. One last thing, I couldn't find in Gnome or KDE where to set the screen resolution when using the linux driver, it's not a problem with Catalyst. There was a display settings where I could set the grey scale and display layout where I could arrange multiple monitors graphically but that was it and it seems like I'm missing something in that respect. I don't know if that is just the way the new Linux is or if that's a related issue or a separate issue. Perhaps I would need to use nomodset on the command line so it's not all decided by the kernel? Does anyone know about this resolution settings missing as well? Given that the issue happens in an instant and leaves no message I don't really know how to give you more information however if you give me instructions for collecting more information for you I'll be happy to do so. Reg Reproducible: Always Steps to Reproduce: 1. Create clean install of OS 13.1 2. Add all the updates 3. Resize windows across screens or quickly pull window to edge of screen Actual Results: Sometimes kicks you back to the log in screen.
