Howdy, On my new rig, I've got everything installed. I mostly been on a console which has worked without issue. Now I've started using the GUI, KDE, and I'm having issues. I wanted to run a command to generate a xorg.conf file and it generate all the needed info regarding hardware and such since the GUI wasn't working right without a config file. The only one I found is the nvidia one. It is minimal at best. Anyway, when I try to start display-manager, with or without a config file, I get the sddm login. I login and if I just let it sit there, after a minute or so, the monitor goes black. It is still powered up but nothing on the screen at all. I've moved the mouse and pressed buttons on the keyboard to make sure it isn't powering off but nothing. Also, the resolution is pretty low too. It should run in 1080P easily. The card supports 4K I think. The monitor tho has ran 1080P on my main rig before, for years I might add.
I used tail -f to watch a few error logs. I watched sddm, messages and Xorg.0.log. The only thing that got added when the monitor went black was this: Jun 21 13:27:41 Gentoo-1 kernel: nvidia-modeset: WARNING: GPU:0: Unable to read EDID for display device DP-3 Jun 21 13:29:01 Gentoo-1 kernel: nvidia-modeset: WARNING: GPU:0: Unable to read EDID for display device LG Electronics W2253 (DP-3) Jun 21 13:29:02 Gentoo-1 kernel: nvidia-modeset: WARNING: GPU:0: Unable to read EDID for display device DP-3 Jun 21 13:29:03 Gentoo-1 kernel: nvidia-modeset: WARNING: GPU:0: Unable to read EDID for display device LG Electronics W2253 (DP-3) If I let it sit for a good while, it comes back on, sort of. The plasma panel thing on the bottom, where the app menu, clock and all is, doesn't come back tho. Also, the background is just black, no picture like usual. The only thing that shows up is gkrellm. I'm pretty sure plasma died. I thought maybe it was heat, the fan isn't running on the video card or something. Nvidia shows the card between 25 and 30C. The fan nvidia says is at 34%. If that is correct, then the fan is running and heat is not a issue. Out comes the flashlight and a mirror. Yep, fan spinning. According to IR temp thingy, nothing even gets into the 90F area. I think if it was heat, I'd see something getting hot with the IR temp thing. There is two versions of Nvidia driver for this card in the tree. I've tried both, no change at all. Screen goes black and after a while comes back but most of the desktop has crashed. By the way, I ran the tail command over ssh. Sometimes when the monitor goes black, it doesn't come back. I can use ssh to reboot and repeat tho. Did I miss something during the install? Does the error above cause this problem? If so, how do I fix it? If you need info, just let me know the command to run. I monitored all I could think of. The one above is all I saw that showed a problem exists. Given this rig is still in testing, I can reboot or anything else as needed. Thanks. Dale :-) :-)
