Could not install LCD 3.5 Touchscreen Shield @ ODROID C2

Unread postby Ameridroid » Sat Aug 11, 2018 5:08 am

I would like this to be reopened because everything goes right on both versions of Ubuntu until the sudo chvt 1 command is entered. (Please move if this seems out of topic)
The entire board seems to freeze. I cannot see anything being typed and cannot move mouse. I thought may just my screen (connected via HDMI) is the issue so I will remove HDMI. The backlight of 3.5 stays lit but no terminal at all.

Everything goes smooth until sudo chvt 1 is entered.

Any ideas?

This topic has been split from other thread to make a better installation guide.
Let us know the Ubuntu image version and Kernel version first.
Is it 18.04? or 16.04? minimal? or Mate?

Did you run chvt 1 command from SSH or serial console?

Thank you for the update and splitting this.

The version is 18.04, but I have run into the same problem with 16.04 as well. Someone mentioned that it may be an HDMI issue and that I should use SSH. Well I really want to try that but running into the problem with Ethernet connections for et0. Both versions were not mate. I am going to try mate next on the HDMI to try and rule out any OS issues. I will also try UART and see if that work.

I am really sorry to bother you all about this. I should have been testing this more and getting familiar. Just recently the customers have brought this to my attention so I have been digging in.

PS. Thank you T for sticking it out with me on Skype:)

By the way I ran chvt from the the HDMI method. I will do it again from SSH and serial to test.
