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.</div><div><br data-mce-bogus="1"></div><div>My desktop has not locked up. I get on another system and ssh to my desktop and issue a reboot.</div><div><br data-mce-bogus="1"></div><div>A reboot is VERY BAD for me. </div><div><br data-mce-bogus="1"></div><div>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.</div><div><br data-mce-bogus="1"></div><div>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. :)</div><div><br data-mce-bogus="1"></div><div>3. I have many xterms open going to different places, looking at logs, etc. I can't restore these at all on reboot. </div><div><br data-mce-bogus="1"></div><div>4.
