In some cases you are forced to use FGLRX drivers provided by AMD, instead of opensource radeon module - e.g. suspend is not working with radeon module (won't recover).
If also you are GDM user like me, you wil find issue. After the GDM is started only Black screen is showed with some random white pixels (like when GPU is broken or overclocked) on the screen.
To fix the issue just downgrade cogl to latest version under catalyst repo, instead using the Archlinux official package.

I had few times situation when after system update had incorrect sequence. What I mean, it updated nvidia dkms module first and a few packages later kernel was updated. This lead to missing nividia DKMS module during boot, and in my case booting without X11...
The fix of this issue is very trivial, but might be useful for beginners.

Recent update of opensuse packages for Cinnamon, totally made my desktop fonts unreadable. Trying alot of fix tutorials, none of those worked for Adwaita theme. More even, the Adwaita theme was hardcoded(gtk.gresource) whichrequired some additional steps to re-generate the DB used for CSS schemas. But I could find a easy fix, maybe it will be useful for other themes too...

This issue came probably after update of packages, after locking the screen I couldn't get unlocked using the password. I oculd the desktop back (without menu bar) by killing the process of cinnamon-screensaver but it's not the solution....

In somecases you would like to have suspend working but the system is unable to recover from suspend to ram. From Linux Kernel 3.9 we have a chance to configure the new option called 'suspend-freeze'. It's diffrent suspend mode, it does not turn off the computer but it's better than nothing.

I was struggiling with this for almost whole day, I wanted to have Power Button under GDM to hibernate the machine, but the settings applied under gconf / dconf did't work. I'm used as my Window Manager Cinnamon and for Display Manager GDM with opensuse branding.
dconf database seems to be not full/ I could find power management options, probably it's to gconf. But gconf was configured with some action even for gdm user.
