Xubuntu on Alienware 14 R2

don't need anything but linux on this guy.
deleted intel rst
modified bios
  • turned of raid, enabled ahci
  • turned on uefi boot
booted usb with xubuntu and installed os to conventional harddrive
left ssd empty

enabled alternate drivers


enable caching on the SSD

lvcreate -n CacheMetaLV -L 32M xubuntu-vg /dev/sdb
lvcreate -n temp -l 8 xubuntu-vg /dev/sdb
lvcreate -n CacheDataLV -l 100%FREE xubuntu-vg /dev/sdb
lvremove xubuntu-vg/temp
lvconvert --type cache-pool --poolmetadata xubuntu-vg/CacheMetaLV xubuntu-vg/CacheDataLV
lvconvert --type cache --cachepool xubuntu-vg/CacheDataLV xubuntu-vg/root
lvs -a xubuntu-vg

So it turns out that this works fine until you reboot then the rootfs can't be mounted because the init ramdisk lacks some modules
These are my reference links:

I deleted the cache and am going to try again.

Yep following those instructions made rebooting work well.

I was desperately trying to get my Dell P2415Q to work through the displayport for several days.   No matter what I dud the monitor was never detected.  I thought I had an Optimus problem, but no, after 3 days of beating my head against the wall, I power cycled my monitor and voila, 4k output with the Nvidia driver through the displayport.  Sadly I had reinstalled winblows because I thought it was something wrong with Linux on this laptop.
Well Xubuntu back on now, time to re-engage the lvmcache.....

Next step let's get google chrome on here as well as firefox
http://askubuntu.com/questions/510056/how-to-install-google-chrome

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
sudo sh -c 'echo "deb https://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
sudo apt-get update sudo apt-get install google-chrome-beta


Apparently installing beta Google Chrome results in a second apt source being created. This causes an error when running `sudo apt-get update`. To fix `sudo vi /etc/apt/sources.list.d/google-chrome-beta.list` and comment the deb repository.

sudo apt-get update

Ok, now my work VPN solution is Cisco based. Luckily the Openconnect clients work just fine.

Cygwin + syslog-ng

Until I can get a real workstation at work and get off this winblows, Cygwin is my friend.  I am working on some OO programming with PERL and really need to be able to log syslog messages locally. After installing syslog-ng, I couldn't figure out how to run it, till I stumbled on a page that mentioned the syslogd-config command. Initially I had some problems because the /etc/passwd and /etc/group files were not world readable (don't know if that is a side effect of the Legato restore of my laptop or just the default behavior) however a quick " chmod a+r /etc/passwd /etc/group " seemed to help. running syslogd-config yielded this output: > syslogd-ng-config Creating default /etc/syslog-ng.conf file Warning: The syslogd service is already installed.  You can not run both, syslogd and syslog-ng in parallel. Do you want to deinstall the syslogd service in favor of syslog-ng? (yes/no) yes Warning: The following function requires administrator privileg...
