I have experienced similar. I tried Cinnamon on Ubuntu 15.04. Sometimes when it would lock the screen whatever was on the screen is cut into boxes and shifted around like a puzzle. There is no way to get out of this. Going to TTY1 provieds nothing. The LCD goes to power save mode as if there is no video signal. 

My desktop has not locked up. I get on another system and ssh to my desktop and issue a reboot. 

A reboot is VERY BAD for me. 

1. I have many tabs open in chrome. If I need a tab I may lose that on a shutdown. My current, and horrible method, for rebooting is to killall -9 chrome, reboot, and then tell chrome to restore. There must be a better way. I am using OneTab, but that only works if I push a page to that tab. I need an add-on that will save state, even if I close chrome normally. 

2. I may have some files in /tmp that I'm working on as temp. These are deleted at boot. A solution is to end that nasty habit and use ~/tmp instead. :) 

3. I have many xterms open going to different places, looking at logs, etc. I can't restore these at all on reboot. 

4. Reboots take time. 

I'm using an NVIDIA card as well. 

01:00.0 VGA compatible controller: NVIDIA Corporation G86 [GeForce 8500 GT] (rev a1) (prog-if 00 [VGA controller]) 
Subsystem: Micro-Star International Co., Ltd. [MSI] Device 0921 
Flags: bus master, fast devsel, latency 0, IRQ 18 
Memory at fa000000 (32-bit, non-prefetchable) [size=16M] 
Memory at d0000000 (64-bit, prefetchable) [size=256M] 
Memory at f8000000 (64-bit, non-prefetchable) [size=32M] 
I/O ports at df00 [size=128] 
[virtual] Expansion ROM at fb000000 [disabled] [size=128K] 
Capabilities: <access denied> 
Kernel driver in use: nvidia 

At this point I'm debating about dropping down to 14.04 and testing that. Even thinking about replacing my desktop and 
going away from NVIDIA on the next one. My system is c2011 and a new system would help.
