Asked if Scotland's Achilles' heel had been the 14 handling errors they made, Laidlaw said: "It certainly doesn't help against a good team like Ireland but there were frustrating things as well. We're relying on other people now (to win the championship), but the one thing we don't have to rely on other people for is how we approach things and how we perform". A minute later Scotland suffered a further setback when Stuart Hogg left the field with an injury.
Ireland failed to convince for long stretches in their search for a riposte following last weekend's punishing 32-20 home loss to England.
Scotland will meet Ireland in their opening Rugby World Cup Pool A game in Yokohama, Japan on September 22, with the victor in that fixture likely to top the group and avoid a possible quarter-final with defending champions New Zealand.
But after a breathless first half which the Irish edged 12-10, they scored a third soft try for some breathing room and their defense limited Scotland to just a penalty. He said Sexton failed a head injury exam after a heavy fall and a stamp.
There was an expectation that he'd be fit to start Saturday's match against Scotland at Murrayfield in the Guinness Six Nations.
"It probably took us until today to really get a spring back in our step and really get hungry because we can't pass up a second opportunity".
The try was a double blow to Scotland. "Blair Kinghorn was great last week and him being on the bench is excellent for us".
Stockdale has made a habit of picking off wide passes for interception tries, but admitted he can ill afford to take any risks given Scotland fly-half Finn Russell's playmaking talents. Grieg Laidlaw converted and Scotland trailed 12-10 with more than 10 minutes to halftime.
"He's definitely the kind of player that if he sees you going for it, he'll let you think you're going to have it, and then he'll put the ball past you, or in behind you".
Laidlaw and Carbery exchanged penalties as Ireland maintained that nine-point advantage, and so it stayed, leaving Ireland mightily relieved to head home with the win.
Ireland have named a much-changed lineup to face Scotland at Murrayfield on Saturday, with a host of injuries making what was already a hard game into a huge challenge.
"Scotland will look to try and replicate how England played against Ireland, the speed of the defence that the English had, and see if they can put Ireland under the same amount of pressure".
The game will be only Farrell's second Six Nations appearance.
