some problems on Ubuntu 20.04

no 3dinfo program, where could I find it, please? I use instead hwinfo --framebuffer --gfxcard | grep -E '^[0-9]|Driver:' | tr -d '\n, it seems to work
running in verbose mode displays the message Redundant argument in printf at ./Run line 1784. (missing a %s ?)
at line 734 Debian-like systems are missing, I fixed it with elsif ( -r "/etc/debian_version" ) { $info->{'system'} = getCmdOutput("cat /etc/debian_version"); }
sometimes it crashes at line 935 due to the fact that $count = 0, would it be possible to add a test like if ($count > 0) { ?
