I honestly think that the Nvidia driver is terrible and very badly integrated. -- 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).
