Richard Tait's debut goal secured an opening day win for St Mirren as football returned to St Mirren Park.
The full-back's header was enough for Saints, in competitive action for the first time since a 1-0 win over Hearts in March, to pick up all three points in Paisley.
The win means that the Buddies have won there last three home matches on opening day and extended our unbeaten run at home in the league to six matches.
There was very little of note in the opening stages with it taking until 20 minutes for either side to register any real opportunity with Livingston's Efe Ambrose having an effort from the edge of the area held by Jak Alnwick.
Saints took the lead with their first real opportunity on the half-hour mark. Jamie McGrath swung the most inviting ball into the box allowing Richard Tait, who had ghosted into the box, to bullet home a header from six yards out.
With a little over five minutes of the first-half remaining, Craig Sibbald cracked the Saints post with a powerful hit from range.
Livingston started the second-half strongly with Alnwick getting the slightest touch on an Alan Forrest effort after the Livi winger had jinxed his way into the Saints box.
Nicky Devlin should have done better for the visitors six minutes later when he stuck a free header from close range over the bar.
Ambrose had a shot from the edge of the area deflected over with Joe Shaughnessy, a colossus at the back on his Saints debut, clearing the resultant corner.
Substitute Junior Morias should have wrapped the game up with eight minutes remaining. The forward was unmarked 10 yards from goal as he met an Jon Obika header but he smashed off the post.
Again Saints could have sealed the points when Shaughnessy rose well to meet a pinpoint Cammy MacPherson cross but nodded wide.
Scott Pittman came close to an injury time equaliser with a strike from the edge of the box, but as they had done the whole match, the Saints defence stood up to block to secure a well earned three points and a much deserved clean sheet.
