1.If I do dispcal -r with a connected instrument it asks to measure patches; problem solved. dispread - prints usage information. 2.I have been unclear, sorry. I do supply a basename for the .ti1 file (it's called "Schermo.ti1"). Here, I just managed to reproduce this behaviour again: ludovico@gogo:~/Desktop/Targets/display$ dispread -k schermetto.cal Schermo dispread: Error - tcgetattr failed with 'Input/output error' ludovico@gogo:~/Desktop/Targets/display$ dispread -kschermetto.cal Schermo Place the instrument on its reflective white reference Serial no. 310345, and then hit any key to continue, or hit Esc, ^C or Q to abort: On Fri, 2007-12-07 at 12:29 +1100, Graeme Gill wrote: > Ludovico Fischer wrote: > > > I compiled argyll beta 7 on Ubuntu 7.10 64 bits.
