Try using underdeclared arrays instead of subscripted variable names.
Although the latex code generated by your code does compile for me, the
subscripts can cause problems.

e1:x[1]*K[1]+%i*x[1]*G[1]-k*k[2]/m[1]-omega**2*x[1]=F/m[1];
e2:x[2]*K[2]+%i*x[2]*G[2]-k*k[1]/m[2]-omega**2*x[2]=0;
[globalsolve:false,programmode:false];
linsolve([e1,e2],[x[1],x[2]]);

The latex code will 'do the right thing' with the array subscripts.
