Mplayer and framedropping

mplayer -framedrop helps when the image falls behind the sound.
I also had to change -vo x11 to -vo xv, in so that the animation would become smoother.

Font Server

After an improper restart (x-server hung up) the X-server wouldn't start, saying something about FontPath being specified as user:/ 7100 (which it is, in xorg.conf), and that it can't find font 'fixed'. Turns out it was caused by the xfs server. It hadn't started despite a couple of reboots. Doing

• /etc/init.d/xfs start

seems to have fixed the problem. Brilliant!

Fix the sound problem with the firefox flash plugin

This is something that keeps recurring every other linux upgrade or reinstallation. The solution is to simply change the permissions on the plugins directory:

• chmod a+rwx /usr/lib/firefox-xxx/plugins

Putting Nvidia to Sleep

Turns out Hibernation (which now comes with the FC package) can coexist with the NVIDIA drivers. One of the biggest hurdles in the process was the fact that online posters kept referring to 8178 as the latest Nvidia driver. It's not, as I found out by visiting their official website. There, in the download section

• get the driver version - NVIDIA-Linux-x86-1.0-8756-pkg1.run (if you have a 32 bit architecture) and run it as usual.
• In my case I had to downgrade from kernel version 2.6.16-1.2084_FC5 to 2.6.16-1.2080_FC5, since 1) I couldn't find the source package for the 84-version, and 2) because I vaguely recalled somebody claiming to have less headache with hibernation after going through the analogous downgrade.
  
• One more thing - not sure if this played any role in making everything work, but following some other guys suggestion I added

Option "NvAgp" "1"
to my /etc/X11/xorg.conf. Probably not, because I put it in the "Screen" section, instead of "Device", where chances are it's ought to be.

• BY THE WAY, installing FC5 onto LVM's doesn't change a thing. Although smartd service stopped complaining. But hibernation is ok.
