Good evening, I am trying to install Qubes 4.0.3 as my primary system but am having issues. I am able to install the OS with legacy by disabling nouveau however there is no such option in UEFI (it's been removed)
I am stuck at a black screen and would appreciate any help.
Solved!
It seems that XEN was not playing well with my nvidia gpu, to fix this I opened "disk" (on linux) and mounted the XEN partition (called Anacoda). I opened the EFI folder and found the config file.
I added "nouveau.modeset=0" after the qubes-verbose section and it works!
I hope this helps any any all who wish to enjoy qubes!

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.

Goal
I was attempting to install Elastix 4.0 on a home PC via a Bootable USB, but never had any luck getting it to install past the CentOS7 part (it kept giving me a "Warning: /dev/root does not exist" error).
What I've Tried
My main PC is Windows 10 Pro, so after downloading the latest Elastix 4.0 .iso from "http://www.elastix.com/en/downloads/" (Elastix-4.0.74-Stable-x86_64-bin-10Feb2016.iso) I used UNetbootin to create my Bootable USB for Elastix 4.0. I put the now Bootable USB into the PC I want to put Elastix 4.0 on and started it up.
It gave me the "Install Elastix 4" menu, so I hit enter and waited. Then the install proceeded to do its checks for CentOS7, but ended up getting stuck and gave me an error message "dracut-initqueue[580]: Warning: Could not boot." and "Warning: /dev/root does not exist".
This is where I am stuck and cannot proceed.
EDIT #1: I signed up for the Elastix forms, and someone else also had this issue. They said they downloaded the .iso and used Rufus to make a Bootable USB, and then booted the installation using the Troubleshooting -> Install CentOS 7 using Basic Graphics ... but according to them, that apparently corrupted something else and then they opted to just use a DVD.
EDIT #2: I tested this, and making a Bootable DVD of the .iso does work great for local machines. Installing it via a VM also seems to work without hassle. As a personal goal, I would like to get this working via a Bootable USB.
Research
I did some research but a lot of the solutions I've noticed are using the dd command in Linux to make a Bootable USB for just CentOS7 because it is (was?) known that UNetbootin did not properly make a Bootable USB for CentOS7, and I can't seem to find anything that would assist in making the Elastix 4.0 .iso work properly via a Bootable USB. I did try other tools such as Rufus 2.7, Win32 Disk Imager, ISO2USB, and dd for Windows, though most rendered my USB not bootable at all (Rufus worked OK, but still got stuck at the CentOS7 part). Also, installing via a CD/DVD is not ideal, as I have no CD/DVD drive (and I want to see if I can get this working via a Bootable USB drive).
There seem to be a few guides out there for trying to create a Bootable USB for Elastix 2.x, but nothing for Elastix 4.0. Reviewing those, it looks like the guides reference some files that do not exist in the new .iso (ex: ks_default.cfg). Still, my issue pertains mainly to the CentOS7 error I'm getting so I don't think this is related.
Any assistance with this is appreciated, and if you require more information from my end just let me know. I'm willing to try / re-try anything.
Thank you in advance.

Look for this line, but it may change:
append initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 inst.ks=cdrom:/dev/cdrom:/ks/anaconda-ks.cfg quiet
Change it to:
append initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 inst.ks=sdb1:/dev/sdb1:/ks/anaconda-ks.cfg quiet
Hi there i solve this problem 80%.
i did some manual change at line:
inst.ks=cdrom:/dev/cdrom:/ks/anaconda-ks.cfg quiet
Mine:
inst.ks=scsi:/dev/sdb1:/ks/anaconda-ks.cfg quiet
hd is not recogniced by Centos7.
made my usb bootable with rufus 2.9
then open isolinux.cfg with notepad++
just change the line
inst.ks=hd:sdb1:/ks/anaconda-ks.cfg quiet
where sdb1 used to say cdrom

According this tutorial, I should remove all HDDs I do not want to install chromium OS to during install. I wanted to try this guide on my imac using an external SSD for chromeos. Obviously, removing the HDD isn't an option. Will the chromiumOS installer format my mac drive too, if I don't remove it?
AS the writer of that tutorial I can hopefully help you. When you install Chromium OS to begin with you can specify where to install to if you know your unix commands well enough. and then from there you can update to Chrome OS once you have your external working for you.
To find out what your hard drive is when connected, open a terminal (you may need to use a developer terminal) and use the command "fdisk -l" This will list your hard drives. for example /dev/sda1 etc...
Your install command would be "Install /Dev/sda1" but replace the dev part with whatever your hard drive was listed as. If you need further help email me at admin#xiaorishu.co.uk
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!
Trying to create a virtual machine using VMPlayer, I discovered that as the Chrome OS is now a Release Candidate, it is only available here: http://www.getchrome.eu/download.php
However, there is no .vmdk download but "Live CD" and "USB Disk Image". I've downloaded the "Live CD", but the VMPlayer couldn't create a new machine. Ive tried several samples from the internet, using the following methods:
Create it as Ubuntu.
Create it as a 2.6.x kernel.
Create a blank VM and point the HD to the .iso file.
I keep getting" "Failed to mount RW root filesystem" and then there's a 120 seconds suspension before a reboot (which causes the same error). The screen shot of the log (Alt+F3):
What am I missing?
In the link you've shared there is no .vmdk (and I couldn't find it around the web). So if I were in your shoes I would go to: http://www.chromium.org/chromium-os/developer-guide#TOC-Building-Chromium-OS
and try to built it with the spec (cpu, mem etc') that you have on the VMPlayer.
Another option is to try and install a built that someone did: http://www.tomshardware.com/news/chrome-os-google-vmware-download,9124.html
Good luck.
You can try Chrome OS by deploying ready-to-use Chrome OS VMs by hexxeh.
