Some questions that might help narrow down the cause of this crash and the one from Bug 2510731: - Do you have multiple displays attached? - Was there a change in the number of displays before and after hibernation? Did a display fail to wake up? - Did you have the display settings dialog open before hibernating? Thanks!
VERY interesting that you ask. My display setup is somewhat unusual. My CPU is an AMD with an integrated GPU (Raphael), but my primary graphics card is an NVIDIA RTX 5060. I have a 4-port HDMI/USB KVM switch, and both GPUs are connected to it. I assume only one GPU is active at any given time. Whenever I switch between the two GPU outputs, the XFCE "Display Settings" confirmation dialog appears, as if a new monitor had just been connected. I'm still running the same boot session in which the error occurred, and I've noticed something odd. The AMD output appears to be frozen in time—it and is still showing the ABRT bug report window from when I submitted the report. No "Display Settings" dialog appears on the AMD output. However, every time I switch back to the NVIDIA output, a new "Display Settings" confirmation dialog pops up. One more detail that may be relevant: I only recently started using hibernation. It has been somewhat unreliable. Sometimes the system fails to hibernate or fails to resume properly. Other times, the graphical session freezes completely, and I can't even switch to a text console with Ctrl+Alt+F2. Interestingly, if I SSH into the machine and run `systemctl restart lightdm.service`, the graphical session comes back without requiring a reboot. Hope this helps, Jonny
