Fedora 18 on Mythlogic Chaos 1212 (clevo w110er)


Here is a quick hardware compatibility table (this WIP, more soon):

Hardwaref18x64 statusNotes
i7-3612qm works
Intel Centrino 6235 N and BTWorksIt just worked w/o futzing like I had done in f17. 
USB3seems to workGot a USB3 HD enclosure recently (2/17/2013) and plugged in and the drive worked just fine.   Didn't check the  speed to make sure I got USB3 speeds. 
hibernate/sleepWorksfn-f4 seems to work just fine.  I think that is sleep, or maybe hibernate.
audioworks out of boxfn-f3, fn-f5, and fn-f6 all work ok
webcamworksCheese works   I dont' know if the fn-f10 key works
Video/Graphicsworksthe intel stuff is working;  no idea what optimus is doing.   NOTE:  the fn-f8 and fn-f9 brightness keys are working!!!
TouchpadworksDon't know if it has same issue as in f17; doesnt seem like it.  (update after about 5 days, strange touch pad stuff I had under f17 seems gone!!)  Blech, seems like the touch pad wonkiness is present; so far it just happens much less often.
Card ReaderI dunno yet1/31/2013 -- nope doesn't seem to work out of box; will address soon.

SNX -- Checkpoint SSL Extender

I had this working under F17 too, but I will say it was plagued by kernel OOPS that often required a hard re-boot.    I am pretty sure I was actually using a 32bit version of snx.   I tinkered some with getting a 64bit version of snx; but that wasn't' so forthcoming.    Like on f17, I followed some of the suggestions on these blog postings:

And the 32bit snx stuff is working.   Further I haven't' gotten the kernel OOPS yet; while far from thorough testing, it was pretty much guaranteed to happen every snx session under f17 64bit.  Sadly (as 1/27/2013), the kernel oops have come back!   32bit snx on f64 is still pretty unreliable.     Since mid-March 2013, I have been on more recent kernels 3.8.3 xxxx and 3.8.4 xxxx and have had much better luck with snx -- no crashes.    Not sure if just lucky or there has been some fixes some where, kernel or or snx otherwise. 

Video and nVidia Optimus and F18

Initially, I will do the disable nVidia thing.  So here is what I did:

su - root
cd /etc/modprobe.d
vi blacklist-noveau.conf
# add the following:
#blacklisting nouveau
blacklist nouveau

#write/quite vi

cd /boot
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img   #optional but recommended
dracut --force /boot/initramfs-$(uname -r).img $(uname -r)                   #rebuilds initramfs w/o nouveau
cd /etc/boot
vi grub
#   rdblacklist=nouveau nouveau.modeset=0
# to end of line initializing GRUB_CMDLINE_LINUX

#write/quite vi
grub2-mkconfig -o /boot/grub2/grub.cfg      #fix up grub menu

Upon reboot, nouveau should not be loaded anymore, verify with lsmod.
