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
