Affects me too, and it recurred with the next kernel via unattended- upgrades.
Ubuntu 24.04 HWE, RTX 4070 SUPER (+ AMD iGPU), nvidia-driver-595-open 595.84. On 2026-09-24 unattended-upgrades installed linux-generic-hwe-24.04 7.0.0-34 but kept back linux-modules-nvidia-595-open-generic-hwe-24.04: "Package linux-modules-nvidia-595-open-generic-hwe-24.04 is kept back because a related package is kept back" After reboot there was no nvidia.ko for 7.0.0-34; the display fell back to simpledrm. Root cause: the noble-security pocket is not self-consistent. linux-modules-nvidia-595-open-7.0.0-34-generic 7.0.0-34.34~24.04.1+1 is published in noble-security and depends on nvidia-kernel-common-595 (>= 595.91.07), but 595.91.07 exists only in noble-updates (noble-security has 595.84). With the default unattended-upgrades config (security only), every kernel bump leaves the system without a working NVIDIA driver. Expected: publish nvidia-graphics-drivers-595 595.91.07 to -security together with the restricted modules, or don't publish modules into -security that need a driver from -updates. The kernel meta should not upgrade when the matching nvidia modules can't be installed. Workaround: sudo apt install nvidia-driver-595-open linux-modules-nvidia-595-open-generic-hwe-24.04 and reboot immediately. On a hybrid system this loads nvidia-drm live, which removes simpledrm from under the running GNOME session and freezes it until reboot. The package source is linux-restricted-signatures-hwe-7.0 / linux-restricted-modules-hwe-7.0, so this bug probably needs a task on that package too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2167531 Title: linux-modules-nvidia-595-open missing/conflict for kernel 7.0.0-31-generic (dual monitor fails) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-595/+bug/2167531/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
