Since I have upgraded from 16.04 to 18.04 my boot time has increased tremendously. I cannot understand the problem after looking at my dmesg. Please help me to find the exact problem. dmesg Edit : systemd-analyze blame

  • When booting, in the GRUB menu, press e, and delete the options quiet splash, then press f10. You will see the full loading of the kernel. Check out where does the system slow down. – schrodingerscatcuriosity Sep 19 '19 at 13:57
  • Please edit your question and add the output of systemd-analyze blame (the first 20 or so lines are relevant). – Jos Sep 19 '19 at 13:57

I've noticed you have kernel 5.1. How are boot times with an official Ubuntu kernel from the repositories? – mikewhatever Sep 19 '19 at 14:10

Read the lines 176 - 179 of your dmesg carefully. As to be seen in line 218 you have radeon-graphics and can delete 'nomodeset' out of grub securely.-watnu
