Catalyst (fglrx) with GDM @ Archlinux

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.

Cinnamon, Font color fix for Adwaita

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...

Use suspend-freeze with hibernation instead of suspend-to-ram

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.

How to enable power button under GDM

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.
