I tried booting with systemd a couple months ago on 14.10. Everything seemed to work except one item: KDM didn't load. The package is lacking a .service file. I tried hacking one up based on examples in other distros but never got it to work. Sure, I could switch to LightDM, but I'd rather keep my computers as pure KDE as possible.

It seems...

It seems that the next Monday is the day - http://irclogs.ubuntu.com/2015/03/05...el.html#t17:03

Riddell we could do with someone testing that first 17:04
yofel systemd runs fine for about 2 months here already 17:06
yofel the only thing I ever had problems with was sddm when we had the systemd support enabled 17:06
yofel er... disabled ofc 17:07

A quick test with the 15.04 - https://wiki.ubuntu.com/SystemdForUpstartUsers:

Switch for a single boot
In grub, select "Advanced options for Ubuntu", where you will find an "Ubuntu, with Linux ... (systemd)" entry. This will boot with init=/lib/systemd/systemd...

Seems to work at here - http://unix.stackexchange.com/questi...svinit-in-bash

With KDE Plasma 5 KDM is being replaced with SDDM and I do know that SDDM does work with systemd.

[deadite66]

Switched early to systemd (apt-get install systemd-sysv).
All working fine apart from cifs shares in fstab needed modifying to mount properly and the pc isn't shutting down or restarting properly, screens turn off but pc not shutting down. maybe related to the cifs shares.

EDIT: looks like systemd not shutting the pc down is effecting others.

Yep. Seems there's no reliable SDDM for 14.10; at least there wasn't when I looked about five months ago. I haven't moved any of my machines to 15.04 because I use all of them for work.

Monday

After:

sudo apt-get dist-upgrade

Change:

Reading package lists...
Building dependency tree...
Reading state information...
The following packages will be REMOVED:
upstart
The following NEW packages will be installed:
systemd-sysv
The following packages will be upgraded:..

...and everything is quiet on the beach...

I am not in a position to try networking at the moment, but I have not had any problems with systemd at this stage. Just for the heck of it, I removed the password prompt and measured the boot time with my stopwatch. I am running 15.04 from a sandisk usb 3.0 flash disc and the boot time for SDDM is 18s and for systemd it is 19s. So there is very little difference in speed. Bugs are another issue of course. So far I have not found any related to systemd.

[GerardV]

I dual boot with SolydK (which, by the way, gives Kubuntu a real run for its money) and this is the boot time with Systemd with a SSD:

gerard@solydxk ~ $ systemd-analyze
Startup finished in 6.322s (kernel) + 1.612s (userspace) = 7.935s

I tried the same code in Kubuntu, but it does't work, but seems quicker still

[GerardV]

After the last update the command

systemd-analyze

now works and this is the output:

gerard@gerard-Satellite-L750:~$ systemd-analyze
Startup finished in 3.674s (kernel) + 1.375s (userspace) = 5.049s

Amazing!
