I am experiencing long boot times on my Ubuntu Desktop (>5min.) and during boot there is either no output to my monitors (dual, DP) or there is a stream of scrolling horizontal static. Finally the login screen will appear as normal. I log in and there are never any issues with the display after that.
VGA compatible controller: NVIDIA Corporation GA102GL [RTX A4500] Driver Version : 535.113.01
I've looked at so many other posts but can't find the same scenario. I checked the boot log and there are a number of warnings/errors. Like these:
May 30 09:46:15 kernel: You have booted with nomodeset. This means your GPU drivers are DISABLED
May 30 09:46:15 kernel: Any video related functionality will be severely degraded, and you may not even be able to suspend the system properly
May 30 09:46:15 kernel: Unless you actually understand what nomodeset does, you should reboot without enabling it
May 30 09:46:15 kernel: nvidia: loading out-of-tree module taints kernel.
May 30 09:46:15 kernel: nvidia: module license 'NVIDIA' taints kernel.
May 30 09:46:15 kernel: Disabling lock debugging due to kernel taint
And the top processes contributing to the boot delay are:
>systemd-analyze blame
2min 37ms systemd-networkd-wait-online.service
1min 392ms apt-daily-upgrade.service
15.082s fstrim.service
9.107s plocate-updatedb.service
6.348s snap.lxd.activate.service
6.141s snapd.service
5.732s NetworkManager-wait-online.service
But this is my first Linux machine (or any machine). What settings and other logs should I check? I'm afraid of doing something that will cause it to not boot at all. Because otherwise it is working fine.
