> There is no documentation about resetting the monitors status to default in this case.
The closest thing to a reset that GNOME has is: 1. rm ~/.config/monitors.xml 2. Log in again. > Even worse, two identical monitors are seen from Ubuntu with a slightly different refresh frequency. In theory that can happen due to different ports or cables measuring different bandwidth. The kernel driver measures the currently available bandwidth in order to limit the set of modes offered. So it sounds like you might have a suboptimal connection on one of the monitors. > Do you have a good doc link on the "best practices" to setup this hw configuration? I am trying to avoid weird suggestions from the community (which change over time). There is no best practices doc for Nvidia multimonitor. And I can say that being the engineer who has overseen Nvidia support for the last few years. All I can say is we're making it better in each release. The change in 24.10 I mentioned is also in the release notes: https://discourse.ubuntu.com/t/oracular-oriole-release-notes/44878 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2085893 Title: [nvidia][xorg] Ubuntu 24.04 shell crashes on 3 monitors Status in gnome-shell package in Ubuntu: New Bug description: This bug happens every single day, even after rebooting and updating. I have 3 4k monitors with 150% zoom (extended mode). On the late evening, I lock the workstation and the monitors goes to sleep (the PC is still wake up and stays accessible all the time from the network). Every morning I log into Ubuntu 24 and the 2nd and 3rd monitor are mirrored instead of extended. From the configuration there is nothing you can do to set the correct configuration. I have to disconnect the 3rd monitor and reattach. But as soon as I reattach the monitor, the Ubuntu shell crashes (the white screen with the logout button). I repeat: this happens every single day. This morning i tried to use ubuntu-bug to report the logs, but the ubuntu-bug hangs the machine completely as I reported in another manual bug two minutes ago. For this reason the attached log is the same as it contains both events. I have two NVida RTX4060Ti plugged in: - one is virtualized in a VM using IOMMU (not used at all by the host) - the other is used by the host for all the three monitors If I use the embedded Intel graphics for the third monitor, the monitor configuration is completely drunk (monitors shows a zoomed shell and there is no way xrandr or the shell settings can fix it). What hardware can be used on Ubuntu to have a stable working workstation? I reinstalled Ubuntu 3 times to avoid issues with the Upgrade from 22 to 24 and still the machine hangs/freezes even on a totally different hardware (with AMD hardware the situation is even worse).
