Title: Slow boot (~3 min) on old laptop
Post by: Sprintrdriver on May 19, 2019, 03:54:01 PM
I have running LL 4.2 for about half a year by now. From the very first boot after LL was installed, it took some amount of time for it to boot. Last OS installed on the same laptop was LL 3.6, and back then it bootet very fast compared to now.
Hope you can help me find the reason why. I'll try to add as much information I beleive is needed.

Thank you very much - it boots very much faster now  :)
Problem solved

Can't beleive it was that easy . . .
Maybe there also should be a hint for this in welcome screen (or maybe something else if that will cause overpopulation of welcome screen) ?
