Hello, I’m using root_v6.26.10. It compiled on the Linux server without problem. When I remotely access the server using ssh via my PC (macOS Monterey 12.2) and test the event display, I get the following error, and the display is empty.
cd root/tutorials/eve
root -l arrow.C

Another test with alice_esd.C also gives empty display.
