ATI & Nvidia: Resume, Good News, Bad News

ATI & Nvidia: Resume, Good News, Bad News
If you're using ATI or Nvidia's binary drivers on a laptop, you've probably noticed that resuming from suspend & hibernate doesn't work so well. The fix is pretty simple, but definitely not intuitive.
Hit alt+f2 (or if you use KDE whatever their runbox thing is...or use a terminal)
Type in gksu gedit /etc/default/acpi-support (replace gksu gedit with kdesu kate if you use KDE)
Scroll to Line 17, which says MODULES="" and put fglrx (if you use ATI) or nvidia (if you use Nvidia) in the quotes
Save and exit
This will make the computer automatically unload your ATI or Nvidia drivers when you hibernate/suspend and reload them when you resume. If for some reason it still doesn't work perfectly (like the 3D is gone when you come back), try turning off Compiz before you suspend or hibernate. I've seen that mess with things too.
In the realm of good news, ATI has agreed to release open source drivers for Linux, just like Intel did years ago. Yay! In the realm of bad news, Nvidia still has not. We want to put pressure on Nvidia to rise to ATI's and Intel's challenge, do we not? Please take a moment to sign the Open Letter to Nvidia asking for fully free and open source 3D-accelerated Nvidia graphics drivers for Linux (8,264 signatures at time of posting) and Digg It. In case you aren't aware, there are 2D open source (barely...the code's fairly well obfuscated) Nvidia drivers on Linux, but that's not good enough for games or for Compiz. Nouveau has been working on creating these 3D open source Nvidia drivers for a while now by reverse engineering and doing lots of hardware probing. For now, they've got better 2D than Nvidia's own open source driver (haha) and some experimental 3D support on the cards the developers have in their own computer and therefore get to mess with the most.
