Send CTRL+ALT+F1

[FinnTux]

Hello,

I noticed VM console window now has Start, Stop etc buttons to control the VM. Thats a great feature. How about sending key combinations other that CAD? At least CTRL+ALT+F1(-F4) would be useful. That would make it possible to switch to another virtual terminal on linux consoles.

sounds reasonable - do you plan to implement yourself?

I'm afraid I don't know proxmox well enough to do that. Furthermore I'm not that much of a programmer.

Also the Posibility to send TAB via VNC would be nice.

OK - will add to our TODO list

I actually figured out a way to add "CAF1" button to the menu. While adding "CAF2" and "CAF7" buttons I realized that "Send Key" button like described in the above bug report (feature request) is much better way to do it.

Altough I'd like to see a fix to the TAB problem in linux desktops first...

Someone needs to find the difference why it´s working on Windows and not on Linux. (Most times it´s the opposite...)

Please, can you give me some pointers to start searching? What code is involved for that bug?
Thank you

We use the tigervnc java console, and qemu-kvm as vnc server.

Sorry, but I could not verfiy it.

Yesterday "TAB didn't work n Linux (Windows not tested) now I want to verify it and it worked on Linux and Windows.

So forget it

Ok, I tried the proxmox '/usr/share/vncterm/VncViewer.jar' (tigervnc) to connect to a VNC server and the TAB key behaves correctly.
So the problem must be in 'pvemanagerlib.js'. I can suggest a workaround:
Edit file '/usr/share/pve-manager/ext4/pvemanagerlib.js'
at line 1842
for the applet parameter 'Show Controls' change the value from 'No' to 'Yes'
before:

{tag: 'param', name: 'Show Controls', value: 'No'}

after:

{tag: 'param', name: 'Show Controls', value: 'Yes'}

Now TAB works from Linux desktop. The side effect is to show the applet controls.
For me this is much more acceptable than having TAB not working from Linux desktop (using Windows only to connect to ProxMox console was not a valid option).

Same here. Working TAB is a must in the console and I rarely have windows desktop in front of me. Thanks.

Interesting, but I do not understand why that influences the behavior of the tab key? Any ideas? Please can you ask on the tigervnc lists if anybody there can explain the behavior?

I'm not completely sure that is an applet fault. As I already wrote, the applet alone seems to work correctly.
The command:
$ java -jar VncViewer.jar HOST <host> PORT <port> "Show controls" No
gives me a VNC viewer without controls and with working TAB key.
Maybe the problem is coming from your "js code" interacting with the applet.

How I can influence keypress behaviour of java applets from outside???

Anyways, I will do a code review tomorrow - maybe I can find something related.

I can confirm this, setting this value to yes leads to a working tab on Linux. Lets see.

TightVNC has fixed similar sounding problem:
http://www.tightvnc.com/changelog-java.html

"Disabling focus traversal keys under JVMs 1.4 and higher. This fixes the problem with not sending Tab key events to the VNC server."

"Traversal key" keeps coming up when googling for this.
http://readlist.com/lists/lists.sourceforge.net/vnc-tight-list/0/1688.html

Something to get started with?

What if you run the applet inside the browser (without our js code)?
