Hi,
I have an sporadic problem with my media server, currently running Leap 42.3. Typically it is running kodi full screen (on XFCE desktop). I leave it running on the night (it is also server for other things full time), so I just power off the display.
Well, sometimes when I power back on the display it remains "dark grey", ie, black with backlight on; there is some signal, but it is black. No response to keyboard at all, that I can see. Most times I can not switch to console text mode. I can do ssh from another machine, tasks are running. I kill kodi if it still there, kill the screen saver, "chvt 1", "init 3"... nothing works, the display does not respond. I have no resource but reboot the server.
I suspect that Kodi has crashed but not fully exited, not restored the display it grabs (full screen mode).
Happened again and got more info; I was able to recover the display.
kodi chrashed, yes. After sometime, the display wen black. Moving the mouse it restored. I had other things to do, so I left it be. After a while it went black, and longer afterwards the display itself powered off completely. Not "standby", but fully off.
Eventually I used the remote control to power it back on. Black. Moved mouse, touched keys... no response. I knew the machine was responsive because I had been doing things on it for hours via ssh. Thinking that screensaver could be triggered, I carefully typed the password and enter. No response. Ctrl-alt-f1... no response.
I removed the cable, which is connected to "HDMI1/DVI/PC" and connected it to HDMI2. No response, the remote control said there was no signal there. I connected it back to HDMI1, and this time I got signal: I could see the result of the Ctrl-alt-f1 I did before. Ctrl-alt-f7 got me back to the normal graphical display. I see my password typed as a command on the terminal, so the screensaver and lock was not active.
Ideas?
It is running Leap 42.3 and XFCE.
The display is a Samsung.
In settings, display power management is "off". Screensaver is disabled. Yet the display itself goes dark and later powers off, something which kodi impedes when it is running.
I will try enabling power management of the display in XFCE, setting "switch off" to "never".
is display/power management enabled in the bios? dpms ?? -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
