I have been searching for a few days and and even thought my problem was related to a reported bug but it seems different.
I apologized if this is reported already and I missed it.
When I resume from suspend UbuntuGnome 13.10 x64 the screen is black and I cannot recover without power down.
1. This is my home built desktop and I have Nvidia GT9800 video card and I have tried both Nouveau and proprietary Nvidia 3.19 driver which I used previous in Ubuntu 12.10 (not Gnome)
2. My monitor is getting a signal on resume because it comes out of sleep mode. In fact it goes from the gray screen to solid black after resume.
3. Ctrl+Alt+F1 does Not bring up a tty session. Going back to Ctrl+Alt+F7 does not help either.
4. I tried changing Settings > Brightness & Lock to Never turn off screen but no help.
5. During normal operation if I let the screen blank after 5 mins (not suspend) it works just fine.
6. I have been using this desktop for many years and suspend with Ubuntu 11.x, 12.x (not Gnome) was no problem.
I have Ubuntu Gnome 13.10 32 bit running on a laptop and it resumes fine although I am not sure that means much for this problem.
My next step is to try Ubuntu 13.10 live usb key and see if I can suspend / resume. I will try the same version Gnome Ubuntu 13.10 on a live key and see what happens there as well.
Any other ideas?
Thanks in advance.
