Unable to make screenshot with <PrintScreen> key in Unity session in Trusty

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks, this is a bug in unity-settings-daemon that is fixed in lp:~laney/unity-settings-daemon/always-gnome-screenshot which should be uploaded to trusty soon

This bug was fixed in the package unity-settings-daemon - 14.04.0+14.04.20140221-0ubuntu1

---------------
unity-settings-daemon (14.04.0+14.04.20140221-0ubuntu1) trusty; urgency=low

  [ Iain Lane ]
  * Always use gnome-screenshot directly, not the gnome-shell screenshot
    interface. We aren't using the legacy keygrabber under Unity, but
    neither can we use gnome-shell's interface since Unity doesn't
    implement it. (LP: #1282649)

Thank you for the fix. <PrintScreen> now works in Unity session.

I did some tests (see my Google Docs table - https://docs.google.com/spreadsheet/ccc?key=0Ao5e713Ig9g_dHpGYVlMZ2JuYXdXdEtmUi1QbGxsYXc&usp=sharing).

In Ubuntu 12.04 (with no matter Unity or GNOME sessions) the full working list of shortcuts used for screenshoting is as follows:
* PrintScreen
* Alt+PrintScreen
* Ctrl+PrintScreen
* Shift+PrintScreen
* Ctrl+Alt+PrintScreen
* Ctrl+Shift+PrintScreen
All these hotkeys work normally in 14.04 too on GNOME FlashBack session (Compiz and Metacity), but
the following hotkeys for screenshots do not work in Unity session:
* Ctrl+PrintScreen,
* Ctrl+Alt+PrintScreen,
* Ctrl+Shift+PrintScreen

I can report separate bugs for them if you ask. Please support all screenshot hotkeys.

On today's clean install of trusty daily-image (2014-03-16) the following hotkeys for screenshots do not work in Unity session:
* Ctrl+PrintScreen,
* Ctrl+Alt+PrintScreen,
* Ctrl+Shift+PrintScreen

Please fix the bug for them.

I reported separate bug about making screenshots to clipboard in Unity session - this is bug 1295592.

I installed 14.04 (clean install) and PrintScreen doesn't work for me...I opened a bug report https://bugs.launchpad.net/ubuntu/+source/gnome-screenshot/+bug/1295994

Made a clean install of 14.04 beta2 (4cf9e5ef2c1c362317c90312c76cfda0 *ubuntu-14.04-beta2-desktop-i386.iso) and got all shortcuts for screenshots working on all sessions - Unity, GMOME Compiz, GNOME Metacity.
It's great! Thank you!

Installed trusty final and upgraded to the latest packages provided by apt, and I can confirm that the bug isn't fixed.

Clean Trusty install, bug is still there.
My current unity-settings-daemon package is 14.04.0+14.04.20140414-0ubuntu1.

I confirm that the bug persists.
I am currently running Ubuntu14.04 upgraded from Ubuntu 13.10.
Strangely, under my system, I found out that the PrintScreen button works under the Fn+Del key combination. No idea why this happens.

I am currently running Ubuntu14.04 upgraded from Ubuntu 13.10 too. And the bug persists. As well as Arthur, the PrintScreen button works under the Fn+Del key combination.

Dear Arthur and Mario!
For me it seems that this is a hardware issue (keyboard, keyboard driver or something).

As far I can understand Mario has Pavilion DV6 (keyboard photo is here - http://www.nix.ru/include/view-photo.html?good_id=118704&pid=2253). According to photo of the keyboard Fn+Delete combination is an undocummented combination. May be keyboard driver identifies keyboard hardware layout wrong.

Could you, guys please install 'x11-utils' package (with 'sudo apt-get install x11-utils') and run 'xev' program?
This program collects all graphics server input events (keyboard, touchpad, mouse and other buttons). Please do the following steps:
1. Open gnome-terminal
2. Send command 'xev -event keyboard'
3. Press PrintScreen button on keyboard. Copy 'xev' output below KeyRelease somewhere (text editor or launchpad comment).
4. Clear gnome-terminal from which 'xev' was started (Terminal - Reset and clear or <Alt>,<t>,<l>).
5. Press Fn+Del button on keyboard. Copy 'xev' output below KeyRelease somewhere (text editor or launchpad comment).

I have Asus UX32a laptop (keyboard photo is here http://www.nix.ru/include/view-photo.html?good_id=148803&pid=2253).
I can make a screenshot only with <PrintScreen> key on any session of Ubuntu 14.04 and 12.04.

For <PrintScreen> button 'xev' produces the following output:
    KeyRelease event, serial 44, synthetic NO, window 0x3e00001,
        root 0x9d, subw 0x0, time 2797480, (-339,166), root:(448,218),
        state 0x0, keycode 107 (keysym 0xff61, Print), same_screen YES,
        XLookupString gives 0 bytes:
        XFilterEvent returns: False

On my laptop <Fn+Del> means <Insert> (see keyboard photo), so it does not work as <PrintScreen>, 'xev' reports the following:
    KeyRelease event, serial 44, synthetic NO, window 0x3e00001,
        root 0x9d, subw 0x0, time 2894533, (-324,567), root:(463,619),
        state 0x0, keycode 118 (keysym 0xff63, Insert), same_screen YES,
        XLookupString gives 0 bytes:
        XFilterEvent returns: False

I have a Hp Pavilion dv7 and I am experiencing the same problem... But in 13.10 all worked fine..

Same problem in hp-pavilion-g6. It worked fine in precise.

Dear guys with HP Pavilions, please collect information about keys as described in comment 14.
It looks really interesting.

Here is my print :

KeyRelease event, serial 28, synthetic NO, window 0x4200001,
    root 0xa1, subw 0x0, time 1202331, (831,420), root:(880,472),
    state 0x10, keycode 218 (keysym 0xff61, Print), same_screen YES,
    XKeysymToKeycode returns keycode: 107
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

My fn+print gives insert too.

@Aaruni
so what is the label on key, which produces "keysym 0xff61, Print"? Does key label equal to its functionality?

@Norbert, yes. "prt sc" produces "keysym 0xff61, Print"

@Aaruni
Does this "prt sc" button produce a screenshot?
If not, it looks strange.

I tested Ubuntu 14.04 on 3 my laptops - I'm able to make screenshots on all of them on all sessions (see my comments 5 and 6).

@Norbert : "prt sc" does not produce a screenshot, although, <alt>+prt
sc produces a screenshot of the currently active window.

also, not that the behaviour of prt sc in Ubuntu Precise 12.04LTS on
the same computer is as expected, ie, to take a screenshot.

Dear all,
I still suspect that the problem is between laptop keyboard and its driver.

I have a new idea.
Could you please connect USB (or Bluetooth, or Wireless) keyboard to your HP Pavilion's and test <PrintScreen> from it.
As I know from my table (https://docs.google.com/spreadsheet/ccc?key=0Ao5e713Ig9g_dHpGYVlMZ2JuYXdXdEtmUi1QbGxsYXc&usp=sharing#gid=0), all shortcuts works normally on all sessions of Ubuntu 14.04 (Unity, GNOME FlashBack Compiz, GNOME FlashBack Metacity) on my 3 laptops (2 Asus - T101MT, UX32A, 1 Sony - VPCF13Z1R).

So please test <PrintScreen>, <Alt+PrintScreen>, <Ctrl+PrintScreen>, <Shift+PrintScreen>, <Ctrl+Alt+PrintScreen>, <Ctrl+Shift+PrintScreen> on Unity session with external keyboard.

Dear Norbert,
Sorry for not responding earlier. I had no usb keyboard at home so I waited till today to do it at the work.
I confirm that the PrintScreen USB Keyboard button works well.
Here are the results for the USB Keyboard testing:

@Arthur Hrast Essenfelder
so all screenshot-related functionality works normally with USB-keyboard, but does not work with laptop keyboard, am I right?
So PrintScreen hotkeys work normally in Ubuntu 14.04.

It seems that your problem with HP Pavillion-s is not related to this bug 1282649 and to bug 1295994
and you need to report another bug on linux-image-generic and xserver-xorg-input-all.

Exactly.
Using the USB keyboard everything works fine, however using the laptop keyboard there is this problem.
I will report another bug as suggested.
Thank you.

Please post the link of the new bug that you are going to report

I do not have an external keyboard to try this out, but the fact that
prt sc works perfectly under 12.04 Precise and Windows 7 makes me
think its something wrong with Trusty.

Even after a fresh Trusty install and applying updates afterwards, the printscreen and all associated key combinations (alt+prtsc), the screenshot does not work. I do not have this issue with my up-to-date Saucy system.

As a temporary fix, change the keyboard shortcut for screenshots to "ctrl+M"

For those interested, I opened a new bug as suggested by Norbert.
Bug #1313754

I'm seeing this issue on Trusty but not on a laptop, and with a USB keyboard:

KeyRelease event, serial 28, synthetic NO, window 0x4000001,
    root 0x296, subw 0x0, time 440656382, (72,58), root:(492,110),
    state 0x10, keycode 107 (keysym 0xff61, Print), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

That's the key event that doesn't trigger a screenshot on my computer. The keyboard shortcuts dialogue registers it as the "Print" key when I try and change the screenshot shortcut to it, so it looks like unity sees the key correctly, it just doesn't trigger a printscreen event.

As advised by someone above, the temporary solution to remap the
screenshot key to Ctrl+M works.

Hello,

I have an Apple Aluminium keyboard without a print screen key.
Usually I set F16 to take a screenshot but it doesn't work in Ubuntu 14.04.

I hope you can fix it. In the meantime I set Ctrl + M to take a screenshot.

I didn't have this issue until yesterday after some updates.This problem was fixed for some people and "activated" for others including me.Now if i press PrintSc key nothing happens.I have a Lenovo laptop.Luckily i can change the key but it used to be standard on PrintScreen key.

Same problem on HP Pavilion G4 2306la
Print screen works on wireless keyboard, in 13.10 also it worked very well.
Every function related to the key "Print Scren" (alt/ctrl/shift....etc+print screen doesn't) work.
Here is my output of xev -event keyboard when pressioning Print Screen

KeyPress event, serial 25, synthetic NO, window 0x4c00001,
    root 0xb1, subw 0x4c00002, time 6378036, (59,37), root:(59,627),
    state 0x10, keycode 218 (keysym 0xff61, Print), same_screen YES,
    XKeysymToKeycode returns keycode: 107
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 28, synthetic NO, window 0x4c00001,

    XKeysymToKeycode returns keycode: 107
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

I have version unity-settings-daemon 14.04.0+14.04.20140414-0ubuntu1, and PrintScreen key doesn't work.

KeyPress event, serial 28, synthetic NO, window 0x4e00001,
    root 0xa9, subw 0x0, time 8225042, (-366,-111), root:(822,479),

    XKeysymToKeycode returns keycode: 107

    XKeysymToKeycode returns keycode: 107
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

Is this already fixed? Is there way without remapping PrScr key? No updates of `unity-settings-daemon`

unity-settings-daemon is already the newest version (15.04.1+16.04.20160701-0ubuntu1).

As of Ubuntu 14.04.5 LTS on HP Pavilion G6, this issue is not fixed.
