SD as shipped from CanaKit worked perfectly in headless mode. But on several reimagines of the SD card, when attempting to open Chrome or Firefox using RDP, the hourglass spins for a minute and then nothing. Same happened on another program trying to open a GUI of its own. I don't know what changed since the original SD other than I'm now using the latest version. And, I cannot find anything wrong other than once, I got an error message that TTY0 could not be opened due to lack of permissions. I ran this:
pi@raspberrypi:~ $ ls -l /dev/tty0 /dev/ttyAMA0
crw-rw---- 1 root tty 4, 0 Dec 8 09:02 /dev/tty0
crw-rw---- 1 root dialout 204, 64 Dec 8 09:02 /dev/ttyAMA0
pi@raspberrypi:~ $ ls -l /dev/tty1 /dev/ttyAMA0
crw------- 1 pi tty 4, 1 Dec 8 09:03 /dev/tty1
crw-rw---- 1 root dialout 204, 64 Dec 8 09:02 /dev/ttyAMA0
I have little understanding of what this might be telling me. I want to use RDP rather than VNC because screen scaling on RDP is MUCH more user friendly. But I have the same issue with both.
I've searched everything I know how to search and other than others reporting the issue, there were no solutions.
Anyone?
