I am experiencing similar issues with a brand new Dell Inc. XPS 13 9300/077Y9N. Perhaps this bug should be renamed for the symptoms and user impact, as there are bunch of linked bugs for specific crashes related to packages? @vanvugt If it's helpful, I have also uploaded (with some struggle

Well, similar experience for me today, booted and logged in okay, but then the desktop session died leaving monitor backlight and keyboard lights on, but no other sign of life. Shutting lid to suspend then resume didn't help, had to hard power off. Then on next boot, it hung after login, but

Okay, pretty sure have found the right upstream bug, and have what looks like a good workaround. $ gsettings set org.gnome.settings-daemon.plugins.xsettings antialiasing 'grayscale' https://gitlab.freedesktop.org/mesa/mesa/issues/2183 The steps to reproduce does kill the session with a gpu hang

@chihchun see bug 1879389 for the apport dump. Because the kernel logs fill up with WARN_ON(intel_wait_for_register(...))/hsw_wait_for_power_well_enable it's hard to find specific other issues. I have observed the sound driver being crashy/sad on the same hardware but it's possibly improved with
