Comment 17 for bug 1321623

Same here.

Interestingly enough it happened both on Ubuntu 14.04 (Unity) and on Mint 17 (Mate), both fresh 32-bit installs. The freezes in Ubuntu made me decide to do a fresh install of Mint 17 (apparently to no avail).

My specs: a rather old HP Pavillion T3640 desktop with Intel Dual Core (Intel Pentium D 3.000 GHZ), 2 GB RAM, Nvidia GeForce 7000 series GPU.

Freeze happens randomly while running Firefox 33, or Chrome, Thunderbird and/or File Manager (Nautilus/Caja). Happens both with Nouveau and proprietary 304 Nvidia drivers. For a while I thought it was GPU/Compiz related since it sometimes happened whilst playing Flash of Html5 youtube video. I also thought resizing windows would cause it, but it also happens without that, so it's really a random matter.

Symptoms: mouse and keyboard freeze. Ctrl+Alt+F* does not work, neither do the Alt+SysRq combinations. Only a hard reboot with power button will do.
