in Ubuntu 20.04; if my mouse is grabbed by a vm and I try to take a screenshot via "Screenshot" - default snipping tool in "Select area to grab" mode-, as I click the "Take Screenshot" button, my mouse icon switches to snip mode but then mode selection window reappears as pressed "ESC" button. In my experience, this behavior appears if your mouse drops to a vm which had already grabbed your mouse.
if you move your mouse to the top bar or side bar, your mouse icon switches to snip mode but it is false positive since when you click it just does not function. And if you click "Take Screenshot" button again, even you successfully take a snap, your click function that brings windows forward, disappears. So, lets say if I use double monitor and each has a window on the front. If I click other window to interact etc, it wont do any good. I can not get my keyboard and mouse in the focus of another window. Also at this point, I can not use top right bar features as well. What I can do is, use ALT+TAB to switch windows. And by this was, I can switch the focus and interact with my mouse and keyboard. I might remember wrong but this was not happening in 18.04. I hope this is fixed soon cuz I really get myself into this trap often, especially if I use double vm which I control each on different monitors. I must remember to use "CTRL+ALT" combo to let loose my mouse from vm's. This is the second VM related issue which I got this year. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1181666 Title: gnome-shell randomly blocks mouse clicks from working in app windows Status in GNOME Shell: Confirmed Status in Ubuntu GNOME: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: Under GNOME 3, the use of the mouse-click stops occasionally, though I can still move the mouse around and can still click on items in the Activities screen and the top-bar. I can use alt-tab to cycle windows and can still type into already- active textboxes in windows, but I cannot click within the windows, and the mouse is not picked up at all by the windows. I can open the alt-f2 "run command" dialogue, but cannot type into it. The workaround I'm using is to open terminal (ctrl-alt-T) and run "gnome-shell -r", and restarting that command every time I have the problem again. Please ask if there's anything I forgot to mention. ADDITIONAL: The error tends to happen randomly, but it seems to happen upon opening a new window, changing windows, closing windows, or opening the activities pane (whether a change of window is thus instigated or not) ADDITIONAL 2: (sorry, it's early) The other workaround is to log out and to log in again, but that is also less than ideal ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: gnome-shell 3.6.3.1-0ubuntu6 ProcVersionSignature: Ubuntu 3.8.0-22.33-generic 3.8.11 Uname: Linux 3.8.0-22-generic x86_64 ApportVersion: 2.9.2-0ubuntu8 Architecture: amd64 Date: Sun May 19 07:02:18 2013 DisplayManager: gdm GsettingsChanges: b'org.gnome.desktop.interface' b'clock-show-date' b'true' b'org.gnome.desktop.interface' b'clock-show-seconds' b'true' b'org.gnome.desktop.interface' b'document-font-name' b"'Sans 10'" b'org.gnome.desktop.interface' b'font-name' b"'Cantarell 10'" b'org.gnome.desktop.interface' b'monospace-font-name' b"'Ubuntu Mono 12'" InstallationDate: Installed on 2013-05-04 (14 days ago) InstallationMedia: Ubuntu-GNOME 13.04 "Raring Ringtail" - Release amd64 (20130424) MarkForUpload: True ProcEnviron: LANGUAGE=en_GB:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_GB.UTF-8 SHELL=/bin/bash SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1181666/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
