Black screen on boot - 2007 Samsung signage

Post#1 by TM8TFY » 02 Mar 2020, 14:39

I cannot get Porteus to install on one of the digital signage panels I have at my workplace.

When I try any other linux distro, I have similar difficulty, which I think is related to display resolution. If I use nomodeset on Lubuntu, for instance, I get much further along, but I still can't seem to get a graphical interface to load. I still seem to eventually land on a black screen with blinking cursor in Lubuntu, though I can CTRL-ALT-2 into a terminal and muck about.

The default resolution of the panel is 1366x768.

Is there a way to get Porteus to try that resolution when it boots, or an even lower one? Am I barking up the wrong tree with the display?

Hi TM8TFY,

Please query me on support@porteus-kiosk.org for debugging ISO.
It will boot to text mode and connect to my PK Server so i could test the GPU driver quickly.

Thanks

If anyone knows how to work through this issue, and can point me to a useful how-to, I am lost on my own.
TIA

I could not get it to work. Monitor is not discovered:

Code: Select all

[  304.877654] [drm] Cannot find any crtc or sizes
I suspected a hardware problem (bad cable or HDMI port) but OP claims that it works under Windows XP so maybe its a kernel driver issue.

Thanks
