Fresh Radeon register dump from when xrandr can fix the issue.

Register dump after xrandr change.
This shows the register status after re-enabling display. This is before I attempt to suspend the machine and is when the lvds display is the only output.

kernel log with drm.debug=1 boot param set
Your system is not dce5, it's dce4. Can you attach the output of the display registers before and after suspend? radeonreg regs dce4 > regs.working suspend, resume radeonreg regs dce4 > regs.broken And attach the results. You can get radeonreg here: http://cgit.freedesktop.org/~airlied/radeontool/ Also please attach your dmesg output before and after suspend. Created attachment 65714 [details]
From a fresh Reboot where I am able to turn on/off the lvds.
The commands related to this output.
# This is on a fresh reboot. Where I have blank screen after I login after the broken suspend/resume.
ken@ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 > regs.working.borkedboot.0-initial
ken@ken-K53TA ~/tmp/radeontool $ env DISPLAY=:0 xrandr --auto
# at this point hdmi-0 returns.
ken@ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 > regs.working.borkedboot.1-hdmi-on
ken@ken-K53TA ~/tmp/radeontool $ env DISPLAY=:0 xrandr --output LVDS --off
ken@ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 > regs.working.borkedboot.2-lvds-off
ken@ken-K53TA ~/tmp/radeontool $ env DISPLAY=:0 xrandr --output LVDS --auto
ken@ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 > regs.working.borkedboot.3-lvds-auto

post resume register tries.
This is after I suspended and resumed. Please note that HDMI-0 returned automatically.
ken@ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 > regs.broken.0-lvds-resume
ken@ken-K53TA ~/tmp/radeontool $ env DISPLAY=:0 xrandr --output LVDS --off
ken@ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 > regs.broken.1-lvds-resume-off
ken@ken-K53TA ~/tmp/radeontool $ env DISPLAY=:0 xrandr --output LVDS --auto
ken@ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 > regs.broken.2-lvds-resume-auto
At this point i rebooted after unplugging cable... it's an odd state to haft to login and issue xrandr over ssh but the lvds returned just like the previous entry.

Created attachment 65705 [details] logs related to issue I am having problems with the system having the lcd panel turn back on after I suspend and resume the system... I am able to get the HDMI to work properly, however the built in lvds does not work correctly at all and this is a major problem for laptop owners.
