Does Crontab always work in the Background? - Raspberry Pi Forums

-

i have pi runs program automatically on reboot using crontab.

pleased in program sends me emails , sends output file designed when run program desktop, opens output window display data produced program.
however, using crontab, window not open , once before on forum said because cron runs in background.

possible add either crontab or program, ensure output window opened.

it runs in background limited environment. starts before gui starts.

getting gui things start cron isn't reliable. you're going need set display=:0 or display=:1 environment variable @ bare minimum.
