Display manager fails to load with fast SSD
I was having a problem with my display manager (LXDM) not loading on my laptop, which has a Sandisk Extreme SSD. Xorg.log would show errors like "No screens found."
I eventually figured out that the problem was that my computer was booting so fast that KMS didn't have enough time to kick in before X was started. I solved by adding the KMS driver (i915 in my case) to the initramfs.
- This is a general problem that needs to be solved in the display manager. GDM already implements the bits for the CanGraphical flag.

Hibernation with systemd
The hibernation section should be considered a hack since systemd does not directly handle the backend that handles power management. Systemd uses the Upower interface to handle such requests

- I talked about hibernation process with Lennart Poettering and he said that systemd-hibernate does only "echo disk > /sys/power/state" . As far as i can see, it works perfectly with tuxonice, since it seems it is now using the same userspace API as kernel hibernation; so it works even without hibernate-script installed (i use it without that package).

- what is the #Hibernation section all about anyway? It makes it sound like you need to use uswsusp to hibernate while it should work out of the box just fine. It doesn't explain at all why you would want to use uswsusp instead of the default command. I don't use hibernate nor do I know what uswsusp actually does, so what am I missing here? ::-- 65kid (talk) 15:12, 25 October 2012 (UTC)
- Hey Nierro, do
systemctl suspendreally do different things on your box? In my setup (linux-pf, systemd 195-2), if I do the latter, my box is also in suspend mode, meaning that my power button is glowing on and off and I don't see grub after pressing the power button again but are back to my desktop almost immediately. To me, it rather seems as if
systemctl hibernategoes into hybrid mode?

- Hey Nierro, do
It isn't clear how to get rid of rc.local. It would be useful to include this statement from the forum discussion in moving from a mixed system to a pure system:
/etc/rc.local.shutdown and turn them into service files (or, if you intend to keep them as they are, copy

- I added a new section Systemd#.2Fetc.2Frc.local_emulation_for_systemd that covers how to emulate
/etc/rc.localin a pure systemd environment. Closing.
Replacing ConsoleKit with systemd-logind -> networkmanager
- 0.9.6.0-2 in [extra] was compiled on 2012-09-19 and the change to systemd was on 2012-09-29, so as far as I can see, it still needs to be recompiled. https://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/networkmanager&id=c34580e6e35b9e87f7dc27f360507143d4fd9106

video group is still needed!
"Adding your user to groups (optical, audio, scanner, ...) is not necessary for most use cases with systemd. The groups can even cause some functionality to break." (Systemd#Supplementary_information)
