Waking / resume not working with new monitor?
by slackerDude from LinuxQuestions.org on (#5S7WZ)
I have a 14.2 base system, some upgrades (mostly kernel + nvidia driver). It hasn't been the most stable (Ryzen 1700, B350 mobo, still not 100% stable). Running nvidia driver 460.67, kernel 5.4.53.
However, here's a new one. Upgraded my 4k Seiki monitor to a 40" Samsung TV (4k@60Hz instead of 4k@30Hz, nicer picture, etc).
Unfortunately, when I turn off the TV at the end of the day, come back the next day, the screen is blank, and nothing I do gets it back. Ctrl+Alt+Delete will kill the Xserver, and it goes back to the prompt (I start it via startx/xinit), I can re-start, and all is well.
So the machine isn't hanging, it's just putting the Xserver into a sleep mode, and then not recovering when I turn the monitor back on?
I remember WAY back when I first installed the new version of 14.2, I had to disable some event from always telling KDE I had a new monitor attached - it would try to reconfigure my desktop every time I turned on my display after having it off for a while. This seems like that, but acting somewhat different.
Any suggestions? I've tried changing power settings to never sleep (but that's a KDE setting, not an X setting), I believe I have DPMS disabled, etc. I've also tried disabled eco features on the TV. I may try a different HDMI port next.
Does this sound familiar to anyone?
