I’m using a VIM2 Max. I recently burned the DualOS to eMMC and the Android/Ubuntu setup worked great in the GUI & command line environment.
However, now I automatically boot into the Ubuntu command line and startx doesn’t seem to work. I have not been able to go back to either Ubuntu GUI or the Android GUI.
The VIM2 Max HDMI is attached to an new HP monitor (not 4K UHD) that works fine. I have a new 4K UHD monitor that just doesn’t work on the VIM2 Max. The 4K UHD monitor does work perfectly on other computers.
I am going to use the UBUNTU 16.04 as a server but it needs to be able to display specific 4K UHD information when required.
I am unable to find the display using xrandr, read-edid and other commands. “Can’t find display”.
1st: Can you explain why I can’t find a display that is connected through HDMI and working fine?
2nd: Once the display is found, I want to setup the default HDMI to auto-connect into 4K UHD mode. Can you explain how I can do this? I can use the cvt command to get the information for the following:
xrandr --newmode “3840x2160_60.00” 712.75 3840 4160 4576 5312 2160 2163 2168 2237 -hsync +vsync
xrandr --addmode ??? “3840x2160_60.00”
The “???” is the required display device name that I can’t locate. Is there a default display name I can use?
3rd: Can I just enter these commands or do I need to write a pre-mount script? If so, where do I put it?
Thanks for your help and have a good day.
