Faster boot tips for linux?
Faster boot tips for linux?
What are your tips for faster boots? My system seems to hang a bit at POST until it boots into Mint. Right after post I'll get a blinking cursor for about a full minute until it boots in. All ssd, so I know it's something I must have done wrong. It's also a 14 year old processor (amd fx be 8 core, rx580), but win### booted faster on it.
Mint uses systemd, so just use it;
systemd-analyze/systemd-analyze blame.You can also visualize it;
$ systemd-analyze plot > boot_analysis.svg $ xviewer boot_analysis.svgThis is so cool. I don't know how yall know all this stuff but thanks for sharing ! My startup is 1 min 21 seconds. I know it should be more like 20 seconds
I think that's really an oversimplification--it really all depends. Systems won't boot in under 20 seconds under all circumstances, and just because your system takes a while to boot doesn't necessarily indicate there's an issue.
But either way,
systemd-analize blamewill help you track down some possible issues and hopefully correct them.Another thing you can try if you're running Gnome, is to edit the
application.desktopfile in your system application launch folder and add a startup delayX-GNOME-Autostart-Delay=60to some non-critical applications that you still want to run at startup. This will ensure that not everything tries to star at once, but you still get all your helpful apps to run at startup.
This is the second time I hear about systemd-analyze, which is funny because the first time was earlier today in that Brodie Robertson video about that pewdiepie video...
Anyway, I checked it out and the only thing I noticed was that cups took a whole second, which wouldn't matter, except that I hardly have a printer to print with anyway, so I disabled it. (could also just remove cups I guess)
I feel like the issue is pretty prevalent in the community as systemd not being incredibly popular with the fogies (myself included). Systemd is expanding at an exponential rate and the documentation is difficult to sift through for niche things like this.
But yes, it does exist and works relatively well.
Considering that from my own experience systemd tends to increment boot times by a factor of about 20x due to insisting about things like raising a wifi interface that won't ever connect because you're later on supposed to plug in the wifi password (no save to store), which is an outright historic systemd problem, I wonder: is
systemd-anamyze blameat least honest enough to recognize the fault is in its own design, or will it always blame it on something else in the system?
Thank you all so much for your help, here is my output of systemd:
It must be something weird with my initial boot. I am dual booting, but on separate hard drives. My PC does have 6 hard drives in it however. Or, maybe something is messed up in my install?

It looks like it's running too often, or on the wrong devices, every time you boot your computer. You can actually safely disable it; https://askubuntu.com/questions/1165128/fstrim-is-causing-high-boot-time but it's worth looking into why it's taking so long and being run so often.
Running this should show you the log results of fstrim doing it's thing without actually doing anything;
sudo fstrim --fstab --verbose --dry-runThese two will show the status of fstrim and it's autorun service;
systemctl status fstrimsystemctl status fstrim.timerI got most of this from a quick google search; https://duckduckgo.com/?q=fstrim.service+systemd+slow You can do the same for the other major time-takers on your boot list. For comparison, here's the top results of my semi-fresh install of linux mint;

Check your BIOS boot settings. AMD FX series should support EFI boot so if you haven't already switch to EFI and disable legacy/CSM support. And if you haven't already turn of PXE boot unless you use it. Sounds like some device has a boot up "bios" device that's hanging the boot process/PXE boot is trying to do it's autoconfigure.
If it is the OS, you could try "systemd-analyze" and "systemd-analyze blame" on the terminal to see what is going on, you can post the output of blame here and maybe someone can pinpoint something strange, or you can search online how to speed up or disable certain elements from the list.
If you post a boot log perhaps it'll help determine what fat can be trimmed
I am going to guess its getting the network up and going. You should be able to hit escape on the screen and see where the boot is in its process. Getting the networking going during boot is something a lot of linux installs will do as most enterprise/devs (tbh the biggest part of their audience) have network attached storage. I have never looked into getting it just to move on past it (it will still start the process for getting networking online, it just shouldnt pause) I know that some fedora installs I have had in the past did this.
But boot it again and hit escape and get more info and if it something else post again here maybe we can help better.
On my last computer I found that the boot process was looking for things that weren't there but that the motherboard had rudimentary functionality for like a floppy drive. It didn't even have a connector for one.
For whatever reason, that caused a 10-30 second delay while the kernel tried to determine if there was a floppy drive connected. Pretty sure I had everything disabled via the BIOS but apparently it wasn't disabled enough and the kernel could still see it.
That required throwing something into the system config, probably somewhere in /etc/modprobe.d, to blacklist that particular kernel module.
There was another problematic module as well; I can't remember what that was, but I'm pretty sure it was the same fix. Got the boot time to login screen down to less than 10 seconds.
But all that said, even on this computer where the boot time is pretty quick, I usually put the computer into suspend mode to keep times down.
Are you positive you mean during POST? Like when you see your motherboard details and such?
It varies wildly from board to board, but if you don't already know what you're flipping around in there, I wouldn't mess with it. You can try disabling certain tests like memory or components checks if everything seems fine operationally.
Off the top of my head I cannot remember the specifics, but there are several options during boot that you can make optional, for instance don't wait until there's an internet connection.
One thing that caused my system to hang for a while before post was leaving my valve index plugged in. I'm not sure why, I guess it's trying to use it as a display output and failing for some reason?
