Thanks for the bug report. It appears you're stuck in software rendering mode because the proper Intel kernel graphics driver was never loaded:
Added device '/dev/dri/card0' (simpledrm) using atomic mode setting. So that's why it's slow at least. Next please run: lspci -k > lspci.txt journalctl -b0 > journal.txt journalctl -b-1 > prevjournal.txt dpkg -l > packages.txt and attach the resulting text files here. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete ** Package changed: gnome-shell (Ubuntu) => linux-hwe-6.8 (Ubuntu) ** Tags added: regression-update -- 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/2077585 Title: my laptop is laggy Status in linux-hwe-6.8 package in Ubuntu: Incomplete Bug description: I have trouble in login.
