Grabbed a Dell G7 7588 (GTX1060), I can see the following behaviour (without the proprietary NVIDIA driver):
* 4.15.47 - Startup finished in 9.204s (firmware) + 12.063s (loader) + 18.618s (kernel) + 35.425s (userspace) = 1min 15.312s - graphical.target reached after 35.321s in userspace * 4.15.46 - Startup finished in 9.960s (firmware) + 26.601s (loader) + 5.682s (kernel) + 21.687s (userspace) = 1min 3.932s - graphical.target reached after 21.675s in userspace * 4.15.45 - Startup finished in 10.107s (firmware) + 10.019s (loader) + 3.652s (kernel) + 20.518s (userspace) = 44.298s - graphical.target reached after 20.501s in userspace Please ignore the time cost in "loader", it the grub menu that I used to switch between different kernels. So if we assume the loader costs 10 second, the start time will be: * 4.15.47 - 73s * 4.15.46 - 47s * 4.15.45 - 44s After installing the proprietary video driver (nvidia-driver-390), the boot time looks ok to me: * 4.15.47 - Startup finished in 13.981s (firmware) + 13.375s (loader) + 3.796s (kernel) + 15.451s (userspace) = 46.604s - graphical.target reached after 15.424s in userspace * 4.15.46 - Startup finished in 8.506s (firmware) + 17.742s (loader) + 8.274s (kernel) + 11.884s (userspace) = 46.407s - graphical.target reached after 11.879s in userspace * 4.15.45 - Startup finished in 8.433s (firmware) + 7.836s (loader) + 2.664s (kernel) + 13.392s (userspace) = 32.327s - graphical.target reached after 13.149s in userspace I guess when booting without the proprietary driver, it's affected by the nouveau timeout issue (bug 1822987) Clement Yuan, can you install the proprietary driver and give it a try? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821027 Title: Feedback on the Dell G7 7588 Boot Time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1821027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
