When running x-setup from the livecd-tools package an error in line 117 from livecd-functions.sh is printed. This is due to the way ATi video cards are detected. The warning is about integer comparison with the variable $ATI_CARD not being an integer. Here is my lspci line: 01:05.0 VGA compatible controller: ATI Technologies Inc RS300M AGP [Radeon Mobility 9100IGP] This can also be fixed by adding |sed -e 's/[^0-9]//g' to line 117.
I've added this to SVN and it'll show up in the next livecd-tools version.
Fixed in 1.0.34 (finally)
