Hi all. So I put the 64bit iso on a usb and booted from that. Then I selecting "try Trisquel without installing" and gnome seems to work fine, except for the panel that is not there. I mean, both the bar supposed to be at the top of the screen and the one supposed to be at the bottom aren't there, the only sign of them is the empty space, created where should be the bottom one, when I make a window full screen where should be the bottom one.
I log out with ctrl-alt-canc then and notice that in the login screen the top one was actually.
Does anyone have an idea what could be the problem?

p.s. an intel dual band wireless-AC 7260 is not good for Trisquel, right?

Yes, unfortunately Intel wireless won't work without a firmware blob
which Trisquel doesn't provide.

Fortunately there are other options, such as buying an internal NIC (if
your computer doesn't block it, as some manufacturers do) or buying a
USB NIC/WiFi adapter.

According to Chris these are the companies that are known to block
internal WiFi cards from working: HP, Lenovo/IBM, Sony, Apple, Dell, and
Toshiba. If you aren't using a recent computer from one of these
companies you might be able to get an internal WiFi card, otherwise you
should definitely consider getting a USB NIC.

It could be this bug, although I can't reproduce it anymore:
http://trisquel.info/en/issues/7703

For me the bug didn't occur very often. Here is a possible workaround:

1. Open terminal (Ctrl+Alt+T) and run "killall gnome-panel" (without
quotes).

2. Press ALT+F2 and run gnome-panel.

First of all, sorry for my first post, it seems written by a drunk person, I don't know why.

Anyways, thanks but your method didn't work. What I don't understand, being me a tech illiterate, is how this kind of bug is possible. I mean, the iso is always the same, but the hardware changes, but can something like this be an hardware problem?

And on a second note what's the quickest way to check if my hardware are ok for trisquel, is testing the only way?

Sorry for asking about two different issues in the same thread, but I don't want to flood the forum.

The ".iso" image is not granted to be the same unless you check the hashes that are shared by the download provider. Nonetheless, it is a shame that you got such an issue. We can probably work this out faster if you tell us what error you were given you when you ran the following command inside a terminal(you can open a terminal with Ctrl+Alt+t)
gnome-panel
After getting the error code and messages (if any) you will need to press Ctrl+C to regain control of the terminal.
You can also try to run this command afterwards:
gnome-panel --replace
It will attempt to terminate the previous panel in execution and start a new one. Again, include any error messages that you get.

The ALT+F2 method to launch programs is not the best, when you need to know if something is going wrong as it will suppress the output.

# About hardware testing
Testing with a Live CD is not a very systematic approach as some hardware will require additional drivers and you will need to reboot (very common with graphic's cards for example), in order to test it properly you will have to test the system as you want it to be in it's future functioning state. Of course, checking hardware compatibility lists for devices like GPUs and Network Interface Cards is a very good practice, since these vary greatly on GNU/linux support.

typing gnome-panel in the terminal just gives me this message "cannot register the panel shell: there is already one running"
if I type gonme-panel --replace it doesn't give me any message back

I tried using the killall command, and the gnome-panel actually disappear from the list of the processes running, if then I type
display=:0.0 gnome-panel
as it was suggested in the link from the user below, the process appear again, but the panel is still invisible

Also, don't know if it matters, but it seems to have other little problems, like for example if I try to open the keyboard layout folder/application/dunno, the cursor loads for a little and then nothing happens. Can it be that the usb is ruined in some way? Cause if I install it on a virtualbox I don't have any problem with the panel.

Also, on this forum, what should I type to use that box to write the commands inside?

Is there no chance that the panel is hidden off-screen? This has happened to me on some monitors. You can change the resolution in gnome-control-center . There is also a tool to popup the menu. It does the same action as if it were clicked by the mouse. It's called gnome-panel-control and it is in the repository.
I am all out of ideas. I would go check the logs on /var/log& and also try to download the ".iso" from the website again and burning it to a different or even the same USB.

Well, thanks anyways. I am pretty sure the panel is not hidden off screen, I tried changing the resolution. Also, whenever I make a window full screen it never go over the area where the panel should be, it stops those 1/2 cm before the bottom of the screen. And if I kill the gnome-panel process, the window goes really full screen, if then I start it again, the window shrinkg again a little. But if click on it it react like if there is just the desktop, also I can move a window over that space.

I tried downloading the iso again but didn't work, now with me I just have this usb but I'll try buying a new one.

I guess I'll have to wait for Trisquel... but I'll make it... hopefully.

You do not "have to wait for Trisquel": you can install any desktop environment you like!

I personally use GNOME Shell (just install the eponymous package on top of Trisquel and choose it at the graphical login screen). There is Trisquel Mini with LXDE. There are the "triskel" and "triskel-recommended" meta-packages if you like KDE. a_slacker_here recently uploaded a script to easily install Unity: https://trisquel.info/en/wiki/how-install-unity-desktop-environment-and-create-session-entry-trisquel-70

And so on.

And it might be that "gnome-panel" will actually work on the installed system!

yeah, you are right, didn't think about it... lol, I guess this stuff confuses me. I'll try to download gnome shell then, after I get the right wi-fi card. This one https://www.thinkpenguin.com/gnu-linux/penguin-wireless-n-half-height-mini-pcie-card is good if now I'm using this one http://www.intel.com/content/www/us/en/wireless-products/dual-band-wireless-ac-7260-bluetooth.html? They look the same but I don't know this stuff so maybe they come in different size.

Testing with the live system is the easiest way to see whether everything works. Otherwise, you can check your hardware against lists of hardware known to work in GNU/Linux without non-free support, or, as you already have done with the wireless, ask about your machine in places like this forum. In the default system, the panel should be on bottom, with desktop having Home, Install, Computer, Trash, and Network Servers icons.

Unfortunately I can't edit my first post, but basically what I meant is that there is no panel. The icons on the desktop are there and from those I can reach oll the other folders, but the panel is still invisible.

Just a thought but if you right click on the panel (where it should be) and click "properties, then background", is it checked for "none use system theme" or "solid color", if solid color, make sure the transparency setting is not too low or it will be "invisible or transparent".

Even if the panel is completely transparent, you can still see the launchers, applets, and indicators on it.

Questions:

Do you still have gnome-panel in your system via apt-get or synaptic?

What happens when you type "gnome-panel" into your terminal (without quotes of course)?
