I'll be happy to collect some debugging info from the command line next time it happens if I get instructions. Thank you guys for your diligence in reporting this issue its obviously important to get this resolved soon. The Window actually works fine, just the screen rendering of the window doesn't redraw. For example, in Chromium, when you click on another tab or open a new one, the Title in the Panel changes accordingly, if we reply to a facebook chat, the reply goes fine, just the window doesnt redraw.
I have worked around this issue by issuing compiz --replace. Since mouse does not work I have a launcher on my desktop to complete the action. Also keyboard commands not work is not entirely accurate, Tab, Enter, and the arrow keys still function. The same thing occured when notebook woke up from blank screen energy saving. Mouse moving, I can increase volume with multimedia keys, but the screen doesnt respond to any keypresses or clicks. Once or twice a day at me two, it doesn't accept mouse clicks but after a while it does, I don't need to reboot.
I see this as well, it occurs anywhere from every half hour to every three or four hours. Dell Inspiron with Intel integrated mobile graphics. No keyboard input is accepted, I can move the mouse but nothing responds to any clicks, even the seconds on the clock are stuck.
I've been rebooting from the console to remedy the issue, I'll try compiz --replace and report back next time it happens. It only happens on this machine, so I'm guessing it's somehow related to the graphics card. I'm surprised this hasn't received more attention. Just had it happen again.
I'm going to try logging into the Ubuntu Classic desktop to see if I can reproduce the issue there, has anyone else tried that? Sorry to post so many comments in quick succession, but this bug is related to screen blanking, i. I can reproduce the bug by closing and opening the laptop lid. It does no occur when using the Ubuntu Classic desktop. Usually either inactivity due to lid closing or screen blanking and I have the same symptoms.
No duplicate of bug for me: it doesn't happen only when closing lid, but also just leaving the laptop alone for enough time; it happens to me times per day, after the upgrade to Ubuntu The process is X. I'll try the "compiz --replace" fix next time, and post an update here.
Hi, 'compiz --replace' didn't work no display , so I had to kill -9 gnome-session also this time. Applications running at the time of the freeze were: - Firefox - Chromium - Thunderbird No LibreOffice applications were running at the time of the freeze, but beforehand. I don't think this has anything to do with the screensaver.
I have an HP EliteBook p with an nVidia video controller and fairly often I get this same problem -- mouse moves around, apps work but the system responds to no keypresses or mouse clicks. Killing gnome-session from the console fixes the problem, but then I lose all unsaved data from the apps. Are you sure that fixed it?
I think the comments on this bug are a mix of different cases, all resulting in graphics hanging. In mine, every single time I opened Open Libre Office applications, or executed some commands from the shell touch, rm, for instance the system hanged as described by almost everyone. Have never had problems with the computer in idle state or some other symptoms mentioned. I can now go back to using Unity.
Lately, I've been having the same issue. My desktop mouse cursor was responsive, but the clicks were registering or being detected. I was able to ssh into this machine when it happened. Also, there were some ibus related processes hogging up gigabytes of memory. Bizarre and a little unnerving. I killed a couple of these ibus related memory hogs, my system came back to normal. So, I think the mouse clicks not being detected was a side effect of the system being under such a heavy load that it couldn't respond in a timely fashion to mouse clicks.
Also, as a side note, I changed my Google Chrome configuration to disallow running in the background. I'm going to try to remove ibus and see if the crazy load issue I wasn't really actively doing anything to stress the system at the time goes away.. Ubuntu unity package. Desktop stops responding to all keyboard and mouse clicks Bug reported by Barry Warsaw on This bug report is a duplicate of: Bug Natty Screensaver freezes system after some period of inactivity.
Edit Remove. This bug affects 26 people. Bug Description. Binary package hint: unity I don't have a way to reproduce this yet, but I believe it is associated with Alt-tab use.

However, the desktop is still grey and right mouse click doesn't work. When I tried to start Terminal using xterm I got the following error message:. Your vnc log file tells you about problem.

Both provides window manager and you need only one. From screenshot I see only two problems - grey screen and missing indicators. To fix missing indicators install one more package: sudo apt-get install indicator-applet-complete. To fix grey screen you need --force-desktop commandline option. Don't forget to install it if you decide to change that. In both cases you also need gnome-flashback.
Install it and make sure it also started. Defaults are configurated for unity-settings-daemon. And to install required packages just do sudo apt-get install gnome-session-flashback. Looks like nautilus does not show desktop icons and background, because desktop icons are disabled. You can enable it with gsettings set org.

I had the same problem. I followed all these instructions I performed a BIOS update and reboot today and experienced the same problem again.

It is a lightweight desktop environment and it help the VNC connection will be stable and smooth. Next, let's run a VNC server instance and you have to set a password for the installed that server:.
As we have are starting server first time after installation it will ask us to set a password that client use to connect. It will also ask to set view-only password which will allow the user to see the screen but not interact with it. Noted that the password length is between 6 and 8 characters. If you enter the longer password, it will be automatically trim off. We call this port as a display port.
We can launch many instances of the VNC server and each instance has its own display ports: the first display listens on port , the second display listens on port and so forth. It's necessary to configure the VNC server to run along with the Ubuntu server startup. By default, the VNC server doesn't use the secure protocol. Launch the terminal on your local machine macOS or Linux , run the following command:. Then, click on 'Add' button as the below:.
It doesn't allow every machine just connects to port Now, you can connect to the remotely Ubuntu server using the a VNC client. In this tutorial, we use the VNC viewer. You can control the server as if you're working with a physical server in your office. For example, you can access the file manager, launch a program or open the terminal:.
