Package: gnome-shell-extension-pixelsaver Version: 1.30-1 Severity: critical
Enabling the Pixel Saver GNOME Shell Extension freezes GNOME immediately. No mouse or keyboard input is accepted. Only Alt+SysRq+k gets me out of it. On subsequent sessions, i.e. with Pixel Saver previously enabled, GNOME will freeze when any window is opened. I supposed that's when Pixel Saver's code gets called. Upon freezing, and getting killed with Alt+SysRq+k, sometimes GNOME disables all Extensions on the next session (probably a failsafe). As soon as I enable the Extensions, GNOME freezes immediately, making it impossible to disable Pixel Saver (greyed out when Extensions are disabled). Uninstalling gnome-shell-extension-pixelsaver solves it all. I got a couple segfaults on dmesg, like this: gnome-shell[11082]: segfault at 78 ip 00007f01cbb92b57 sp 00007f01937fd420 error 4 in libglib-2.0.so.0.7400.6[7f01cbb07000+8d000] likely on CPU 0 (core 0, socket 0) I do not get them everytime GNOME freezes, therefore I don't know if it's related. On rare occasions, I was able to run sessions with Pixel Saver enabled (and visually working) without any freeze. The freezing returns upon restarting the session. I was unable to reproduce the (rare) conditions which enable Pixel Saver to run smoothly. I was able to reproduce all this on 2 different desktop machines. Both x86_64, running Debian 12 bookworm with kernel 6.1.0-10-amd64 and GNOME Shell 43.6 on Wayland. Apart from that, all hardware (CPU, GPU, motherboard, display) is different.
