I recently got Jack_fst functioning on my Mandrake 10 box for the first time. It is working very well and I am very pleased... I am primarily running a GM2 synth called Edirol Hyper Canvas. I have tried 2 versions with this same issue... "The program 'jack_fst' received an X Window System error. >This probably reflects a bug in the program. >The error was 'BadRequest (invalid request code or no such operation)'. > (Details: serial 16653680 error_code 1 request_code 0 minor_code 0) > (Note to programmers: normally, X errors are reported asynchronously; > that is, you will receive the error a while after causing it. > To debug your program, run it with the --sync command line > option to change this behavior. You can then get a meaningful > backtrace from your debugger if you break on the gdk_x_error() >function.) >[oz@fx oz]$ " It runs fine for a time and then this occurs and shuts it down. Any thoughts?? Thanks R~
