As a follow up to my bug report, it could be useful to add the logs. The freezes appear to be reported as: [user] acpid: client xxxx[0:0] has disconnected
A relevant excerpt from my log is: Jun 18 01:18:34 [user] acpid: client XXXX[0:0] has disconnected Jun 18 01:19:53 [user] gdm-Xorg-:0[XXXX]: (II) NVIDIA(0): Setting mode "CRT-0:nvidia-auto-select" Jun 18 01:19:54 [user] acpid: client connected from XXXX[0:0] Jun 18 01:19:54 [user] acpid: 1 client rule loaded Jun 18 01:19:54 [user] gdm-Xorg-:0[XXXX]: (II) NVIDIA(GPU-0): Display (DELL ST2310 (CRT-0)) does not support NVIDIA 3D Jun 18 01:19:54 [user] gdm-Xorg-:0[XXXX]: (II) NVIDIA(GPU-0): Vision stereo.

Jun 18 01:21:23 [user] acpid: client XXXX[0:0] has disconnected In that instance, the desktop froze at 01:18:34 and never stopped until a reboot. Audio can still be heard during the freeze. Potential solutions: 1) After searching for similar errors, I found a number of entries about client disconnects on various Linux forums. I came across a suggestion to reinstall acpid. I reinstalled the package and haven't experienced a freeze since, but I cannot confirm if this is really a fix. 2) Another bug report (#780553) <780...@bugs.debian.org>was solved by installing Cinnamon 2.6. I will test this possibility. In any case, if anyone knows why this bug occurred, please let me know.
