I have two completely unrelated problems that I hope someone can help me with. I'm kinda new to all this so go easy on me
1) when trying to compile a program i get the following:
checking for valac... no
checking valac is at least version 0.1.6... ./configure: line 21334: : command not found
yes
checking for vapigen... vapigen
checking for python module xdg... yes
checking for intltool >= 0.34... 0.36.2 found
checking for perl... /usr/bin/perl
checking for XML::Parser... configure: error: XML::Parser perl module is required for intltool
2) trying to install nvidia drivers but i need to stop the xserver. Is there a boot parameter so i can boot without it one time or a code i can stick in on o/s selector
