Unfortunately there are multiple issues. Those GTK apps crashing with signal 5 appear to be related to GSettings schemas being out of date, preventing the app from launching. That's caused by a broken system upgrade so check that your upgrade to 25.10 is really complete with nothing left to resolve:
sudo apt update sudo apt full-upgrade Separately, one of those crash reports mentions that the Nvidia kernel and user drivers have different versions: kernel: NVRM: API mismatch: the client 'ptyxis' (pid 72780) NVRM: has the version 580.82.07, but this kernel module has NVRM: the version 580.65.06. Please make sure that this NVRM: kernel module and all NVIDIA driver components NVRM: have the same version. That is also an upgrade problem (which might explain the performance issue). To resolve it I would do: sudo apt update sudo apt install linux-modules-nvidia-580-generic-hwe-24.04 sudo apt full-upgrade -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2127046 Title: GSK_RENDERER=vulkan wakes dGPU up on first app launch.
