Hi, I have installed Fedora in a VM and gpsim worked without problems. I think the problem is in Ubuntu the pkg libgtkextra-x11-3.0 is different, so it's not a gpsim issue. I didnt know different distros could have different libraries, so I'll just use gpsim with with Fedora. Thanks for your support, if you need more info from me let me know. BR
