*****************************************************

I have recently, re-installed fresh ubuntu 13.10 distribution release. But everything worked fine. until recently i had strange problem of my display screen getting freezed randomly; but no response to either mouse/keyboard.
But i want to point it out; it happens randomly and is not specific ?
Other day, i had music player playing in background, but screen freezed. but my music was still running.
Kindly note, i used multiple monitor setup and same issue of screen freeze also cropped up.

Have seen the same running 3.9.0-3-generic #8-Ubuntu SMP Tue May 28 18:40:41 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
 issue decreases greatly when compiz effects are disabled using compiz config setting manager.

Only way to recover is to control+alt+F3 and give shutdown -r command.

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

[Saha (smirta)]

I confirm the problem. XUbuntu 13.04, kernel 3.8.0-25-generic.
I think this is a problem with X-server.

[Saha (smirta)]

The screen freeze arises mainly while processor is fully loaded

[Phill (phill.l)]

I may be having this same problem but currently unsure as it seems to be tied to Skype use for me, although this might just be a coincidence - my computer is rarely heavily loaded. It was the fact that the other terminals still work that's made me this this is the same issue that I'm having.

* GUI becomes non-responsive (no hovering changes, clicking, scrolling etc).
* Video freezes (in Skype)
* Sound and microphone continues to work normally (in Skype)
* Mouse still moves (clicks don't work)
* Keyboard doesn't work, except to switch terminals
* Text terminals appear to work normally
* Computer doesn't appear to be busy after the freeze (I didn't check CPU, but terminal is responsive and there's no disk thrashing)
* Restarting lightdm has worked once, but display didn't wake-up after its next sleep - direct power-off required.
* Reboot required to get PC working normally again.
* Ubuntu 13.04 64-bit (3.8.0-23-generic)

Does this stack up with the other experiences?

[Daniel Arteaga (daniel-arteaga)]

In my case, every once in a while the screen freezes and the keyboard and mouse stop responding. This lasts for about 0.5-5 sec, and then activity resumes as normal. Makes usage of the computer very incovenient. Cannot confirm 100%, but it looks like it is linked to heavy processor usage.

Using Ubuntu Gnome 13.10 (with gnome ppa enabled) with

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV610
OpenGL version string: 3.0 Mesa 9.1.3
OpenGL shading language version string: 1.30

Any workaround suggested?

[Saha (smirta)]

The problem with screen freezing seems to be solved when I set /proc/sys/vm/swappiness to 0 (probably 10 also will be fine).
And I should note than in my case of screen freezing mouse cursor also stops moving completely. Such freeing lasts from 1 second to ~10 seconds.

[Saha (smirta)]

Unfortunately, problem is not solved... :(

[fyksen (fredrik-fyksen)]

I got the same problem. Tried changing swappiness, but with no luck. It freezes randomly (CPU usage doesn't seem to make any difference).

If it freezes, I can ctrl+tab+f1-6, and then ctrl+tab+f7, and then everything is good again. Anybody else got this?

[Daniel Arteaga (daniel-arteaga)]

Changing swappiness doesn't work for me either...

[Saha (smirta)]

Apropos, please write which graphics driver do you use.
I use radeon.

Below I attach Xorg.0.log when xorg is almost frozen and I need to restart it from terminal.

Short peace of it:

[1048945.485] [mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack.
[1048945.485] [mi] mieq is *NOT* the cause. It is a victim.
[1048945.827] [mi] EQ processing has resumed after 43 dropped events.
[1048945.827] [mi] This may be caused my a misbehaving driver monopolizing the server's resources.

[Shanekpiper (shanekpiper)]

This has been the case for me since 12.04 LTS, when ever the a sound is playing and the volume is up on 100% past the unamplified setting it freezes most of the OS, but the instant that the volume is turned down there is a delay, Linux catches up and unfreezes everything. I have a feeling that Pulseaudio is knotting things up. I'm unsure where the issue lies but this does seem to be the case. I do hope that this does not happen with the Ubuntu Touch OS for mobiles cos I know a heap of people that crank the volume right up to the max. Linux 3.0 has always been an issue for my realtek audio, 5.1 no longer works as standard when compared to Linux 2.6 which was fluid.

[Daniel Arteaga (daniel-arteaga)]

In my case freezes become more infrequent and shorter (but they do not disappear) when I remove the tracker package, so I believe it is somehow linked to hard disk access.

I'm using the Radeon driver:

VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV610 [Radeon HD 2400 PRO/XT]

I haven't seen a link to the sound so far.

No susupicious messages in the Xorg logs.

[Pierre-Luc Gagnon (gagnonpluc)]

Hi all. I too had these issues right after upgrading my system to 13.10. My experience mirrors that of Phill, with a few differences:

* Sound output is sometimes interrupted in my audio player
* Mouse still moves (clicks don't work) BUT it sometimes freezes as well
* The problem occurs in a virtual console as well. Emacs freezes (I can't enter text)
* No reboot required. But sometimes it takes a long time for the computer to unfreeze.
* Ubuntu 13.10 64-bit (3.11.0-7-generic)

Furthermore, contrary to saha's experience, there isn't any correlation between a freeze and cpu load for me. Also saha is running a 3.8.0-25-generic kernel and the freezes don't occurs with 3.8.0 for me (see end of my comment).

I have a laptop with nvidia optimus (intel graphics + discrete nvidia card, however the intel card always drives the display even though the nvidia card might be the source). The problem occurs while using any of the 2 graphics adapters. However a bug in the intel driver could still be to blame, but very unlikely in my opinion. So I don't think this is a graphics issue.

Now, I also have a 3.8.0-30-generic kernel, which I have been using for an hour now. No freezes yet. So I think this is a kernel bug. I think it unlikely to be a problem related to a combination kernel + gfx card because as I mentioned the problem occurs without X too. I will update my comment if a freeze occurs.

I will try different kernels and see what happens and report back.

[Pierre-Luc Gagnon (gagnonpluc)]

Eh the freezes started occurring again, with the older kernel and very frequently too. I thought I was on to something. Oh well.

Also I notice that after rebooting it takes a little while before the freezes start

Maybe relevant info:

Linux 3.11.0-7-generic x86_64

I can do CTRL-ALT-F6 CTRL-ALT-F7 and it works again, but really annoying, can't find anything helpfull in Xorg.0.log or syslog

Do you also have the nvidia-prime package installed?

[Daniel Arteaga (daniel-arteaga)]

In my case freezes disappeared when I removed the gnome ppa (https://launchpad.net/~gnome3-team/+archive/gnome3).

Having the gnome-ppa installed produced freezes not only in gnome-shell, but also in Unity.

[Saha (smirta)]

Sometimes freezes arise when Firefox is running. It seems that something like "out of memory" happens and (as 'top' shows) kswap is active (although I disable swap completely). Pressing Alt+SysRq+F kills Firefox and everything goes well.

[Pierre-Luc Gagnon (gagnonpluc)]

Update: I downgraded back to 13.04 and the problem vanished, thus confirming that one of the upgraded packages is causing it. However, I am still running the 3.11.0-7-generic kernel, so it's something else.

One way to uncover the culprit would be to update to 13.10 incrementally just a few packages at a time and see which one brings back the freezes. I don't have much time these next few days but if somebody could try it, it would save all of us a lot of pain (really can't work like this). I will have a go at it next week. I don't see any other solution unless someone finally finds an error message in a log somewhere.

[Randall (rlague)]

I just upgraded to 13.10 from 13.04 and experienced a frozen mouse cursor after returning from standby. I could still click the mouse and bring up a right-click dropdown menu; however, I could not move the cursor. I had not ever experienced this issue under 13.04.

I hope you're able to pinpoint and resolve the issue.

[Felix Bünemann (felix-buenemann)]

I'm also seeing frequent freezes on Nvidia Optimus muxless system when using nvidia-prime and the nvidia drivers (no matter which version). I think it doesn't happen when I remove the nvidia drivers and only use the intel card.

[pirrax (rpsutanto-googlemail)]

Just installed Ubuntu 10.13 64-bit from ISO yesterday and cannot work with it at all. It freezes already after 1-2 minute(s).

My Computer:

NVidia GTX 580
Ubuntu installed on Plextor 256 GB SSD

[Ajit Natarajan (ajitk)]

I started experiencing this hang after I upgraded from Kubuntu 13.04 to 13.10 yesterday (both 64 bit).

The freeze usually happens when I try to context switch between windows running Firefox or between Firefox/Thunderbird windows. It also happens when I close windows. The problem is not consistent (i.e., happening on every switch/close) but happens fairly frequently. Ctl-Alt-F1/Ctl-Alt-F7 does not always help.

Recovery takes several seconds.

A reboot does not fix the problem, i.e., hangs happen after reboots.

Follow up to comment 25.

Sometimes the hang happens even while browsing within a Firefox window.

I saw the following in dmesg around the time of the problems. I tried Ctl-Alt-F1/Ctl-Alt-F7 and the graphics screen hung (black screen with moveable mouse cursor). I do recall seeing the login screen for a moment and the black screen right after I logged in again. I then rebooted the system.

[Christopher Nelson (nadiasvertex)]

I can also confirm this problem. It happens to me in Unity on a repeatable basis: whenever I click the mouse on the desktop to draw a selection, everything freezes momentarily. It doesn't happen when resizing or moving windows, just when I click on the desktop. However, it does happen if I try to maximize a window in Unity

This happens in Gnome3 in other situations, especially in Eclipse.

I am using the nvidia-319 driver in the Ubuntu repo.

[Ajit Natarajan (ajitk)]

The problem disappeared when I switched to the nvidia propreitary driver.

$ dpkg -l | grep nvidia
rc libkwinnvidiahack4 4:4.10.5-0ubuntu0.2 amd64 library used by nvidia cards for the KDE window manager
ii nvidia-304-updates 304.108-0ubuntu1 amd64 NVIDIA binary Xorg driver, kernel module and VDPAU library
ii nvidia-common 1:0.2.83 amd64 transitional package for ubuntu-drivers-common
ii nvidia-settings-304-updates 304.88-0ubuntu2 amd64 Tool for configuring the NVIDIA graphics driver

To me, this means that the problem is in the noveau driver since nothing
else changed in my configuration.

[Dylan (nucleotidex)]

Can confirm this affects me on newly clean installed Ubuntu 13.10. Unity, Gnome Shell, it doesn't matter. Doesn't seem to have much rhyme or reason for when it freezes either.

[StSav012 (stsav012)]

In my case, both screen and keyboard freeze completely (even SysRq don't work). Once I left my PC frozen for an hour, and no avail.
Once it happened while watching video. Sound was looped; some a half of a second was being repeated. Then in several minutes it stopped.
I noticed the increasing of CPU load while freezing, for the cooler is rotating much faster at the moments.
I'm using Ubuntu 13.10 after upgrading from 13.04. Previously, I haven't noticed anything like this.

[Letatcest (ksoeteman)]

I don't use Firefox as my standard browser, so I didn't notice it myself. When other people use my computer, they have to use firefox, as I don't want them to use 'my' browser (chromium). It only seems to happen when Firefox is in use and I've seen it happening. It's quite annoying. Screen freezes for ~30 sec or even longer. Only sysreq-keystrokes still work. Cannot find anything in logs (or maybe I haven't checked the right logs).
I am not entirely sure, but in all cases an instance of Libre Office had been used as well, which is also something I never do (use gedit or google docs...). But I haven't been able to recreate the problem. It seems completely random...

[Mattia Impellizzeri (matt-91web)]

my computer freezes and reboot. This sometimes when i open dash
i not find any useful logs

[Michael Horgan (mhorgan)]

It also affects Chrome as well as the entire system it seems for me.

[Cimdrap (giosaci)]

same problem here after few minutes i start using a browser. I thought it was zram related issue and upgraded the kernel to 3.12, but the problem persists

[abdozzahra (sehagh)]

I have the same problem with intel graphic card. freeze time to time.
by enabling hot corner in desktop and move mouse to corners in freeze time , i can unfreeze desktop

[Gustavo Rocha (gustavorocha-deactivatedaccount)]

Same to me. But I didn't see cpu, memory, and hard disk fully load. I see that the mouse and the system freezes ...sometimes comes back, sometimes not!

hello, I'm also affected by gnome freeze (forcing me to reboot) when using the maximize function (by dragging the windows on top of the screen) :(

I have the same problem as described by many in this thread. Ubuntu-studio v13.10, kernel 3.11.0-13-generic

MSI GE40, NVIDIA GeForce 760M, nvidia-319 & nvidia-331 both cause problems with nvidia-prime (muxless system)

GUI will completely lockup randomly & infrequently... mouse/keyboard doesn't visually update, but I think things continue to happen (just doesn't update on the screen). Switching to a text terminal (ctrl+alt+f2) FIXES the problem and things resume normally (until the next lockup).

Hoping for a fix!

For me it starts hanging about 10 minutes after it starts using Swap.

I'm going to point the finger at something in xorg, as the 14.04 beta has been behaving perfectly.

[Imre Széll (konzerwe)]

i have this issue on a freshly installed trusty (kubuntu) & asus x550lb notebook, nvidia geforce gt 740m (using proprietary driver) , with an elantech touchpad. additionally, when the problem occurs, the following message is logged to the syslog:

acpid: client 11187[0:0] has disconnected

switching to character mode and back after waiting a few seconds makes the problem disappear and the i see in the syslog the following:

acpid: client connected from 11187[0:0]
acpid: 1 client rule loaded

i reported the bug as https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1313902

Happens for me too, after enabling compiz on xubuntu trusty tahr with Nvidia GTX 760 and nvidia official driver.

I needed compiz, because otherwise I have screen tearing.

[Oleg Cherkasov (o1e9)]

The same problem with 14.04 on Lenovo T540p using NVIDIA. It seems if I am using UltraDock with mouse and keyboard no issues however with trackpad the coursor may freeze eventually and the only way to fix the problem would be C-A-F1 and then back C-A-F7.

This bug affects me also,
but somehow up to now only under heavy CPU load, sometimes clicking into the DASH search bar.
Cursor moves, no clicks, only frozen screen.

GPU 580, NIVIDIA Driver Manual install from NVIDIA Page.
13.10 ubuntu

[SammyA (sda5150-w)]

This bug was affecting me under these specific circumstances:

Ubuntu 13.10 - all updates applied
Hardware: HP Elitebook 8440p (Video is NVIDIA NVS 3100M graphics)
Problem seemed more prevalent when laptop was under load and was getting hot, almost like a CPU thermal shutdown issue..

This problem has stabalised for me since upgrading to 14.04, and have not had an issue since..

Regardless of new report policy for this site... I'm not sure if the mods here are aware, but this page is top hit in Google search for this problem, this is why everyone is posting here...

[SammyA (sda5150-w)]

Spoke too soon... Just crashed again :-(
It is certainly more stable though under 14.04 but not 100%

[penalvch (penalvch)]

SammyA, thank you for your comment. Unfortunately, 13.10 is EoL as of July 17, 2014. For more on this, please see https://wiki.ubuntu.com/Releases . However, so your hardware and problem may be tracked, could you please file a new report in a supported release by executing the following in a terminal:

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

Thankyou Christopher,

Bug report submitted :-)

[Andrey Konstantinov (andreyinvolute)]

Exactly the same issue on Asus N550JV laptop (hybrid graphics: Intel HD 4600/nVIDIA GT 750M), fresh install of 14.04, nvidia-331. Random lockups when using nVIDIA card, no lockups at all when using Intel. Lockups happen more often when nVIDIA card is under load (for example, playing Civilization V).

[penalvch (penalvch)]

Andrey Konstantinov, unfortunately, this bug report is not scoped to you, or your problem. So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via:

Exactly the same issue on Ubuntu 14.04.5 LTS, laptop DELL Latitude E6440 with Intel Graphics.
Sometimes it happens ones per 2 weeks, sometimes every 2 days.
