Ubuntu: Screenlock = death



Question:

So, I'm a newbie and I've loaded Ubuntu Studio (16.04) onto a Compaq 8000 using a "DP Display Port to HDMI Converter" to my LED TV and I'm loving it, EXCEPT for this problem.

When the Display times out (for long periods) I cannot get it back. If I hit and/or play with the power button, I can USUALLY get back to the password screen, but can NEVER get back into my locked session When I type my password it goes blank screen again (it WILL let me in as another user and it works). Rarely I am never able to revive the display, at all, forcing a power cycle.

I think the problem MAY be limited to ONLY those occasions where the display times out and then the TV turns itself off (from lack of signal - figure 30 mins).

Quick & Fast: I'm willing to "never" suspend the screen if that's what it takes but I can't even find out how to do that, I seem to have a maximum time limit of 60 mins. I'll be great if somebody can tell me (remember, running ubuntu studio default installation - seems to not offer "never" as a screen timeout)

For those who love to be problem solvers: - Here are some details that MAY be useful based upon what I've browsed, not sure:

rick@Ubuntu1:~/.local$ lshw -c video  WARNING: you should run this program as super-user.    *-display:0                      description: VGA compatible controller         product: 4 Series Chipset Integrated Graphics Controller         vendor: Intel Corporation         physical id: 2         bus info: pci@0000:00:02.0         version: 03         width: 64 bits         clock: 33MHz         capabilities: vga_controller bus_master cap_list rom         configuration: driver=i915 latency=0         resources: irq:30 memory:f0000000-f03fffff memory:e0000000-efffffff ioport:1250(size=8) memory:c0000-dffff    *-display:1 UNCLAIMED         description: Display controller         product: 4 Series Chipset Integrated Graphics Controller         vendor: Intel Corporation         physical id: 2.1         bus info: pci@0000:00:02.1         version: 03         width: 64 bits         clock: 33MHz         capabilities: bus_master cap_list         configuration: latency=0         resources: memory:f0400000-f04fffff  WARNING: output may be incomplete or inaccurate, you should run this program as super-user.  

=========

I also noticed files below (in case it helps)

rick@Ubuntu1:~$ cat .xsession-errors  openConnection: connect: No such file or directory  cannot connect to brltty at :0    rick@Ubuntu1:~$ cat .xsession-errors.old  openConnection: connect: No such file or directory  cannot connect to brltty at :0  upstart: startxfce4 pre-stop process (14205) killed by TERM signal  upstart: gpg-agent post-stop process (14206) killed by TERM signal  upstart: startxfce4 main process (1622) killed by TERM signal  upstart: Disconnected from notified D-Bus bus  rick@Ubuntu1:~$  

Anyway, if somebody can point me to a fix that's not too complicated, I can give it a try. Thanks.
