On Topic / HP Printer Driver Website

« on: June 18, 2017, 01:46:50 PM »

FYI... HP Printer Driver Website is back.

Just installed latest printer driver pack. HP do a good job, it looks just like Winblows Version.
All the same tools & diagnostics.
This is "Wizard" to guide you through the install.

Note: For some reason this version(never seen before) tells me another "Package Manager" is running, it wasn't, so I selected ignore.
If you are using a Wireless Printer, pay attention to the very last step, and note what you need to run for final set-up.

Off Topic / Microsoft Surface 3 & Linux 4.8 Kernel

« on: September 26, 2016, 06:55:29 AM »

Just read in the latest Linux User Magazine that 4.8 is probably going to support the Surface 3,
and the speculation is that it will run Linux better than Windows on the Atom CPU...!!!

Built in the smallest case I could find with a single 5.25" inch bay to take the 4 X 2.5" drive bay adaptor.((DVD Case for comparative size))
Sorry, picture not great, from my phone, you can just make out the 4 Drives bays, you can open and change drives.

Here's the "How I Did It" ~ Install "LL-BTRFS - RAID10 ~ 4 Disks"
This is based on info from various sources, did test in Virtualbox first.

Boot LL Live from USB/CD/DVD

First open a terminal and do a

Code: [Select]

ll /dev/sdCheck that you can see all the 4 disks O.K ,
Then
Create Disk Partition(s) (see note at end on swap**)

Open "gparted" and select 1st disk, "sda"
Then go: Device > Create Partion Table, select "DOS"
Then create a "single partitition on each of the sdX's, "DO NOT" select file system type and leave "unformatted"
repeat this for each of the disk: sdb & sdc and sdd. ((btrfs automatically created a /home))
Next
Create File System & RAID for installation.
Open a terminal. (ctrl+alt+t)

Code: [Select]

sudo mkfs.btrfs -L RAID10 -m raid10 -d raid10 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1Next
Start installation, at the where to install, make sure to select "Other"
Just make selection "change" to install on the1st drive "sda1 = /"
>> DO NOT TICK FORMAT <<
Select use as "btrfs file system"
You only need to select the first disk partion "sda1" for "/" and "sda2" if you created "swap"
Click the "Install Now" button. ((btrfs will know to install to all 4 drives))
Click "Continue" to the various dialogue box's about partitions...
At GRUB dialogue box, you will get "Errors", select "Continue" without installing,
When install finishes, select "Continue Testing".

Then:
Open a terminal. (ctrl+alt+t)

Code: [Select]

sudo mount -t btrfs -o subvol=@ /dev/sda1 /target
sudo mount --bind /proc     /target/proc
sudo mount --bind /sys      /target/sys
sudo mount --bind /dev      /target/dev
sudo mount --bind /dev/pts  /target/dev/pts
sudo mount --bind /dev/shm  /target/dev/shm
sudo cp -f /etc/resolv.conf /target/etc/resolv.conf


sudo chroot /target
grub-install /dev/sda
grub-install /dev/sdb
grub-install /dev/sdc
grub-install /dev/sdd
update-grub

Ignore the "Logger Error", The above will allow you to Boot from any drive

Close any open terminals.
Shutdown, remove the LL boot disk, and re-boot.
All being well you should now be in LL, and on Btrfs RAID 10.

"NOTE" - There is an Ubuntu bug that "may" give an error at boot on btrfs, I did not get the error, but to fix it:

Code: [Select]

gksu leafpad /etc/grub.d/00_header

Edit line that starts with: if [ -n “\${have_grubenv}
and change it to: # if [ -n “\${have_grubenv}
Then save & exit and re-boot.

To check basics, open a terminal. (ctrl+alt+t)

Code: [Select]

sudo btrfs filesystem show
sudo btrfs filesystem df /
sudo btrfs device stats /mnt

"Should show status & disk information & no errors."

Carry on with your normal set-up.

**swap
If you have 4GB or more of memory, you probably don't need swap for general Desktop use.
If less than 4GB, create a swap, larger then your memory, say 1.5X or 2X memory.

Printing and Scanning / [ HELPFUL TIP ] HP-LIP - Disappeared...!!!

« on: July 26, 2016, 01:22:52 PM »

Hi,

FYI, This is on LL 2.8, not on 3.0 yet.
I needed to check ink levels on 1 of my printers, printing not looking good.

Went to main menu, typed HP and selected "HPLIP Toolbox"
Nothing happened, NO GUI appeared...
After a bit of Googling/Checking decided to re-install.

Latest HPLIP Install Link

No idea what or when it disappeared, not checked it for months...
Main thing is, I can can now see the printers
