In my laptop installed 128GB SSD and 500GB HDD and I have /, /home and swap on SSD, and store other files on HDD.
/ – 20GB;
/home – 100GB;
swap – 8GB.
All 500GB on /media/storage.
On the HDD I keep only large files that don't need high-speed read/write. It's a music, videos, ISO images, system snapshots, etc. For convenience, in my home ...
The machine is attempting to book to your second drive. There are a few things that fix this:
Reorder Boot Devices in BIOS
By pressing the function keys, ususally F2 during startup (like, as soon as you power on), you can enter the BIOS. Look for a "Boot Order" section of the BIOS (usually one of the last tabs). Find your USB HDD, USB DISK, and/or your USB ...
Setting up a trim job on Freya
You can add the TRIM command to /etc/rc.local. Then this command will be executed automatically on system boot. This hardly slows the boot process down.
You can do that as follows:
Type in the terminal:
sudo -i scratch-text-editor /etc/rc.local
Above the line exit 0 in that file, you now add the TRIM command
fstrim for every ...
from reading the messages on the kernel mailing list I understand that the data loss only is a problem when using the SSD in a raid0 or raid10 configuration.
They have fixed the bug in the kernel, but I can't seem to find in which version the fix was released.
It depends on the size of your SSD. If your SSD is bigger than your current HDD you could just use a live distro like SystemRescueCD and use ddrescue with sudo ddrescue -v --force /dev/sda /dev/sdb Here is a pretty decent tutorial which also covers the case that your SSD is smaller than your HDD.
But -- and that is just my personal experience -- I would ...
Executing trim every boot or weekly won't make a huge difference unless you are constantly writing lots of data. Anyway, make sure your ssd supports it:
Execute lsblk -D from a terminal and check the values of DISC-GRAN and DISC-MAX. Non zero values indicate trim support.
TLP is safe and it's also recommended to use it instead of laptop-mode-tools. So ...
Hi I just received my XPS15 9560 as well and installed Elementary OS dual booting with windows (And of course run into the same issues as you).
You need to install Elementary in UEFI mode and not in legacy mode
In the bios you need to disable secure boot.
Also (an absolute MUST) you need to switch your disk from RAID driver to AHCI, without it you won't ...
You run Gparted and create a swap partition in the disk. Right click on that partition >>information tab.
There you locate UUID and location (ex. /dev/sda5). Then you open '/etc/fstab' (can be opened with Sketch or Sublime) and modify the lines #swap was on <prev dev location> and UUID=<prev UUID> to new data. Save it (you'll need admin password) ...
