Two Zorin 7 Questions

I have been 'playing' with Zorin 7 for a week or so now, as a new user to Linux-based systems, and all seems to be going quite well, with a couple of odd things.

1. I am using a TP-Link wi-fi dongle (WN722N) which the OS picked up and installed fine, and works well. The problem is that, every time the system goes into stand-by mode, when I revive it, the dongle has gone off-line, and I have to unplug it and replug it to get it going again. If I do this, it immediately re-connects and all is fine. But why does this happen, and is there anything I can do about it?

2. Again, the OS discovered my trusty old Laserjet 1220 printer and installed it correctly. When I try to print, the software goes through the motions, the data light on the printer blinks as normal, no error messages are posted - but no printed output appears either! There's nothing shown in the output list and after a prolonged period (a minute or so), the data light stops blinking and all is as before. As I say, nothing indicates any error, it simply doesn't print.

If I switch back to Win7, both of these problems disappear.

Any ideas, experts?

For the 1st problem I think I can help you.
With the dongle plugged in and your internet working, post back here the results of the temrinal commands
lsusb
sudo lshw -c network

For the 2n problem we need to see if there are any linux drivers for your printer.
Is your printer connected via USB or network?
How did you install it?
If it is connected via USB, please post back the result of:
lsusb

Your best chance to get it working is to install from software center the program called HPLIP and HPLIP tools.
Open it and then try to find and install your printer from there.

Otherwise you can download it from here: http://hplipopensource.com/hplip-web/in ... index.html
As I see, your all-in-one-printer is supported.

Here's the results of your enquiry:

~$ sudo lshw -c network
PCI (sysfs)

Printer is connected via USB

Hope it makes sense to you!

Phil

I also need the result of

Code:

sudo lshw -c network

I think the driver you need is ath9k_htc but I want to confirm that.

It takes 3-4 seconds to show the result, so please wait and then post it back here. Thanx!

About the printer, as I said, download HPLIP and HPLIP-tools from software center and try find and to install the printer from there (HPlip program).

Sorry - I didn't wait long enough! Here it is:

~$ sudo lshw -c network

Hi,

install the package "hplip-gui" and install your printer using the HPLip Toolbox gui:

Code:

sudo apt-get install hplip-gui

See the post install guide about "Adding Printers":

About your first problem with the suspend of the dongle, indeed as you have seen, your wireless driver is ath9k_htc.

Open terminal and write:

Code:

sudo gedit /etc/pm/config.d/modules

A file will open. Inside it add the line:

SUSPEND_MODULES="ath9k_htc"

Save, exit, reboot and test if your dongle wakes up after suspend.


About your second problem, I think it is just a matter of installing and using HPLIP as me and Wolfman advise you.

@madvinegar - tried that. See below...

~$ sudo gedit /etc/pm/config.d/modules

** (gedit:28949): WARNING **: Can't load fallback CSS resource: Failed to import: The resource at '/org/gnome/adwaita/gtk-fallback.css' does not exist

(gedit:28949): IBUS-WARNING **: The owner of /home/phil/.config/ibus/bus is not root!

Still working on the printer...

[Update] Printer problem solved - thank you! Still puzzled about the errors above, though!

No problem about the errors. I get the same ones. The important think is: Did the blank document open? Did you insert the line

SUSPEND_MODULES="ath9k_htc"

inside it and then save it, exit, reboot?
Did you try after that to see if your wireless works after suspend?

Interesting! The first time, the file did not open, so I assumed this was because of the error messages.

Having read your reply, I tried again. This time the file did open, though it was empty. I added the line as specified and - woo hoo! The wireless works after a suspend! Thanks again.

Having been wedded to Windows since version 3.0 (yes, I am that old!) it's going to be a bit of a learning curve, but I am already appreciating the advantages of Zorin.

Microsoft lost me for good when I foolishly 'upgraded' to Windows 8!

Great! So both of your issues are solved???
Can we mark the thread as solved?

Interesting, as I made a comment that it looks like they copied Pear OS but badly on another forum and commented that you would have had to have had experience of Gnome3 DE to find your way around! Glad you are sorted - 60 blue jewels in advance to madvinegar!
