So I have Ubuntu 14.04 Installed on my system with a few "tweaks", mainly ccsm. I also have google chromium browser installed as well. I do a lot of work in the browser and usually have 10+ tabs open in my system.
I also like to use the multi-window (Workspace) and have 8 Workspaces (thus one of the reasons for ccsm).
Once I leave the computer and try to come back (before the screen locks), the computer is COMPLETELY frozen with my HDD running at very high speeds. I have a system monitor that monitors the CPU activity and HD activity and right before those things freezes, my RAM is at 100% and so is my HDD.
I'm wondering if anyone can help me FIGURE OUT what the problem is? I've been using ubuntu since '08 so I'm familiar with it. I just don't know where to start!
HELP!
I can not deal with the problem until I install the following packages as follows
sudo apt-get install linux-generic-lts-quantal xserver-xorg-lts-quantal
You could get the detailed reason from http://www.howtoeverything.net/linux/hardware/random-freezes-integrated-hd-4000-graphics
Maybe you have to consider the Google Chrome or Chromium, whose two or more different Flash plugins conflict with each other, and the freeze problem disappear after you Disable the Flash plugins in the webpage opened by inputting
chrome://plugins
in the URL address of Chrome
Or another useful method of changing the chrome plugins is to uninstall the google-chrome completely,and then install the current chrome with newest flash plugin.
After all the above are done, the system need restart.
Hope it can help. Good luck!

I'm making an application with WebVR using React VR. I'll test the application with my Oculus Rift and HTC-Vive. I'm using the browser Firefox Nightly to access the WebVR API's.
If I browse to my application using Firefox Nightly or Chromium, I arrive in an empty space with a loading message. A few seconds later I got this message on my Oculus Rift:
Sorry, firefox.exe/chrome.exe is taking a while to load. If this issue persists, please take off your headset and check this app on your computer.
On the HTC-Vive I got this message in Steam VR but it doesn't load at all.
(unresponsive) firefox.exe/chrome.exe
In the webbrouwser, I got the result I must see inside the headset with motion tracking.
I'm using this browsers
Version Firefox nightly: 55.0a1
Version Chromium: 56.0.2910.0
And this are my specifications:
GeForce: GTX 970
GeForce Game Ready Driver: 378.66
Processor: Intel® Core™ i7-6700 CPU # 3.40GHz
RAM: 15.87 GB
This isn't the Oculus software at all. The problem is an NVIDIA driver update that broke everything. You need to go to the NVIDIA site and download drivers from the "376" generation (Dec'16-Feb'17). Install those and the problems go away. I confirmed that things are working with Oculus 1.12, 1.14, and 1.14 beta channel.
It looked like Oculus broke things because 1.14 came out on almost the same day as the "381" NVidia driver update.
Downgrading my Nvidia driver to 376 worked as a charm for me, but I can't run the VR scenes on Nightly, just on Chromium.
I was able to get my Oculus to work with WebVR by enabling the Beta channel within the oculus app and letting it install an update. Seems like the current Oculus version might be broken.
Try installing SteamVR. SteamVR overrides the Oculus runtime and runs applications on its own.
Try closing Oculus Home before you launch your WebVR application using the WebVR button.
Make sure you are not in the Beta/Dash mode in Oculus
Try to disable the auto-opening of Oculus Home. Oculus home opens automatically on wearing the rift. To disable, select “Run as admin” field in the properties of the Oculus app. More specifically, go to /Oculus-Directory/Support/oculus-client/OculusClient, right click, select properties, check “Run as Administrator”.
Make sure that your Desktop and Rift are connected to the same Graphic card. You might need an HDMI to DVI converter for the same. This is what fixed the problem for me.
Ever since I have upgraded my laptop (Click here for hardware specs.) my screen usually freezes. Mostly in chrome or Firefox browser. I am pretty sure this is a Nvidia driver problem but I can't seem to find the solution. I am running a Nvidia Quadro K2100M.
I am currently running Nvidia 361.42. I have tried using open source Xorg server without any luck.
The only solution I have found so far is forcefully turning off the computer by holding down the power button.
Things that I have tried:
I got keyboard input
I cannot switch to another terminal to restart lightdm
This problem came to me occasionally, making me really annoyed.
As illustrated in many blogs, this may be caused by graphic driver problem. For me, my desktop has a NVIDIA video card, you can run lspci | grep VGA to see what type of your video type, in my case, it returned:
02:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 8400 GS Rev. 2] (rev a1)
I followed the instruction on jiakai zhang's blog to reinstall proper drivers for the desktop, hope this will help you.
The key steps in [1] are to reinstall the ubuntu desktop and nvidia drivier by:
$ sudo su
$ apt-get update
$ apt-get install --reinstall ubuntu-desktop
$ apt-get install unity
$ apt-get remove --purge nvidia*
$ reboot
$ sudo apt-get install nvidia-current
$ sudo reboot
Updating the grub settings worked for me! Do the following:
1. Open the GRUB configuration
sudo vi /etc/default/grub
2. Change the value of GRUB_CMDLINE_LINUX_DEFAULT from "quiet splash" to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"
and save the file.
3. Update & Reboot
sudo update-grub
sudo reboot
More info:
This is a bug in the processor, known as the c-state bug. It causes total freezes when the CPU tries to enter an unsupported sleep state. It's a problem for many Bay Trail devices especially with newer (4.*) kernels. There is a simple workaround until it gets properly fixed upstream. You just need to pass a kernel boot parameter and the random freezing stops completely. The parameter may increase battery consumption slightly, but it will give you a usable system. You do this by editing the configuration file for GRUB as described above.
GRUB - boot loader package from the GNU Project, which provides a user the choice to boot one of multiple operating systems
installed on a computer or select a specific kernel configuration available on a particular operating system's partitions;
Intel Bay Trail - new Atom Processors from Intel. Atom is Intel's family of x86 and x86-64 processors that are optimized
for small computing devices, such as smartphones and mobile Internet devices;
C-States - used to optimize optimize or reduce power consumption in idle mode (i. e. when no code is executed) - (C0 to C8)
Reference: here.
I have since fixed this problem by re-installing Ubuntu 16.04 and not switching from the nouveau video driver. I also disable updates and everything been working good for about 2 months now.
Gaming is pretty good but I usually play steam games so doesn't push any kinda hard core graphics
Well, I had the same problem: My PC was freezing randomly. I tried Ubuntu 16, 17 and 18.04 and everything was the same. I tried several drivers and didn't get a solution. I tried several solutions that I found in the forums (including this) and got bad and harmful results.
My solution was: I stopped using the graphical nvidia card, removed it and now I'm using the integrated Intel HD graphics card (Intel® HD Graphics 530 card (Skylake GT2)) and all the problems were solved!
I fixed mine using a few commands from #Qoros solution above. i just ran apt-get update, apt-get install nvidia-current, and sudo reboot. cheers to #Qoros btw!
For me, none of the approaches described in rest of the answers worked.
I was opening multiple terminal tabs running some heavy processes and ubuntu used to freeze when I had 6-7 tabs. I tried monitoring the resources used while I was starting my processes in terminal tabs. You can do it by opening System Monitor app and going to Resources tab.
What I noticed is that when my RAM(8GB) and my swap space(1GB) were completely used up, ubuntu would freeze.
As a solution, I increased my swap space and made it 16GB. After this memory never gets used completely and ubuntu doesn't freeze.

I am really new to Windows Phone 8 App development. I would be grateful to you if you can answer my question. I have a machine with Intel(R) Core(TM) i3 processor and when checked I found out that my virtualization setting enabled.
I installed Windows Pro 8.1 in to my machine and then it indicates that my Hyper Visor is default switched off and I had to run it. But when I run it after making some of the changes by restarting the machine, suddenly for some unknown reason it undoes every change made finally leaving the machine with no Hyper Visor running.
I come across the same process when I am to run the Windows Phone emulator to test Windows Phone 8 Apps.
I hope my issue is clear to you all, can someone help me to fix this issue or tell me the exact reason behind this?
I would look at my Windows Event log and see if you perhaps there's a problem with Hyper-V being incompatible with a driver or something like that. It may be failing to reboot and the doing a system restore to get the machine back to a bootable state (by rolling back Hyper-V). I've had problems with Hyper-V and my HP laptop's blue tooth drivers:
Here's the thread where I found out about that:
HP Bluetooth / Hyper-V woes
Updating the driver to the newest version on HP's site fixed my computer for a while, but then I had problems with Windows Update hosing my machine with an update to the Bluetooth driver.
I seem to have fixed it for good by going to RA Link's website and downloading a version of the driver that's newer than the one on HP's website. I'm not at my personal computer right now, but if you'd like I can see if I can find the driver version that seems to have fixed my Bluetooth/hyper-v problems for good.

First my specs are an Intel i7 toshiba laptop with 8gigs of RAM running windows 8.1 with all the latest updates. When I first launch any of Jetbrains IDEs after install, it would ask me for my workspace location and then it would proceed to do nothing after than, but it stays in memory and slows down my entire system for about a minute, after that, the computer stops being slow and returns to normal but the program still does nothing (no GUI) but still remains in memory, what is going on??? Thanks in advance.
It's hard giving a definite answer to your question. But it sounds to me like you have a problem with your Java. Make sure you have it installed and at the latest version.
Also, try looking for matching bugs in the JetBrains bug tracker.
Replacing the jre folder within the IDE folder (pycharm,intelliJ,etc.) with one from an updated JDK install not JRE install.
ex:
JDK/jre7 copy over Jetbrains/IDE/jre
fixes the issue
So, I'm developing my rails applications on my mac, thro WEBrick at 0.0.0.0:3000 and I need to test how the layout are showing on PC running Windows with Internet Explorer 7 and IE8.
I have tried to test it thro Wine + Wine Bottler, but I can't access that point.
And now I'm thinking to install VirtualBox to give a try, but before doing this, it will be good to know from others if it will or not work for me in this case.
Any advice?
Thanks!
I use VirtualBox for interface testing. I've had no problems with it at all. I have an external drive with various disk images for firing up various versions of Windows and thus various versions of IE as well as Firefox and Chrome. Works a treat and no complaints.
We have used VirtualBox and a program called IETester:
http://www.my-debugbar.com/wiki/IETester/HomePage
It works well, even for IE6 although there are some very minor differences for IE6.
Makes it very quick to test in all versions of IE as you can have a tab for each.
Give it a go.
