I am running Ubuntu 14.04 LTS inside of VirtualBox. Functionally it is great, it is just very slow compared to 12.04. I've seen some posts about changing the desktop to XFCE and other desktops so that the OS runs faster. I like the 12.04 desktop and am wondering if it is possible to use the 12.04 desktop with 14.04. If so, how do I do this?

For me, the newest edition of XFCE runs really fast, not slower than any previous version (much faster than default Ubuntu desktop).
To install older version of XFCE, choose version you want and download all the files you need from here
Installation manual I recommend is available on this site.
Hope this will help.

I have installed debian 9.3 on HP DL20 Gen9. When Debian 9.3 start, what happen is that the screen of the system appear like on the picture after the grub goes. any help?
Try booting your computer up in safe mode from Grub. Install updates and restart.
If it happens again you probably need to configure your graphics card for your installation.
Re-install Debian 9, when in the Software selection menu,
don't enable Debian Desktop Environment. If you need a desktop environment, simply enable certain Desktop environments.
In this case, I'm using Cinnamon. Until now there are no problems.
Thanks.
I find a solution. I used "nomodeset on the boot", and the screen appear normaly. I have used another tty2 and i get connected with the shell.
nano /etc/default/grub
i find this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
and i have changed it to this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset"
I just bought the new Dell XPS 13 Developer edition which came preinstalled with ubuntu 14.04.
After the initial boot it seemed a bit slow, but then it updated and worked fine, then later the same day seemed to slow down again.
Even running programs like eclipse it seems very laggy on, which is odd. As the specifications should be fine;
16gb Ram
i7-6560U cpu
64-bit
500gb ssd.
I'm not sure what to post to help, so any suggestions would be great.
Thank you!
Check what is using much system load using the command top.
You can also use htop which is easier to read.
For that install it using the following command:
sudo apt-get install htop
Have you tried reinstalling Ubuntu 14.04.3 LTS on your computer?
In future, please use the Ask Ubuntu forums for such questions.
I had a similar issue in my lenovo thinkpad with i7 and 16GB. pycharm and android studio was exteremely slow and it was almost not usable for any development. Even it took a while for the terminal to start.
Finally I found a solution for my issue. I needed to disable "speed step" feature in BIOS.

I need to test a web application on older versions of Internet Explorer. I'm running OSX El Capitan locally.
My preference is to run a local VM (Virtual Box or VMWare) rather than use a service like https://www.browserstack.com, although I'm open to any suggestions or recommendations.
What's the best way to test older versions of IE on OSX?
You can download virtual machines with different versions of IE on them directly from Microsoft: https://dev.windows.com/en-us/microsoft-edge/tools/vms/mac/
They have IE6 all the way up to Edge available. The virtual machines are available for VirtualBox, Vagrant, VMWare and Parallels.
Host machine was ported from 11.10 to 12.04 LTS (Xubuntu)
Virtualbox image is win7 x64
With upgrade /dev/vboxdrv was missing, so within synaptics I reinstalled:
virtualbox (4.1.12dsfg-2 not OSE)
virtualbox-qt 4.1.12dsfg
virtualbox-dkms 4.1.12dsfg
Then it works again but my windows is badly crashed. Once started and desktop icons pops out it's really slow and crash (network icon is also blocked)
I reinstalled guest additions, but does not make any difference.
Nothing is serious because I still have available snapshots.
I'm asking for advices, like for example how do I clean reinstall (clear parameters) vbox ?
Is there any workaround, or do I need to wait fresh 12.04LTS updates to fix this pbm by magic ?
I can confirm this bug on two of my Ubuntu 12.04 machines (i7 Desktop, Samsung Dual Core Laptop):
All my Windows (Win7, WinServer2003,WinServer 2008) 64bit guest machines which were working under Ubuntu 11.10 behave the same way after upgrading / reinstalling to Ubuntu Precise:
During guest bootup or shortly after bootup (sometimes I can even access the guest's desktop for a moment) the complete system host + guest freezes completly.
The Vbox.log doesnt contain any hint. Even a fresh install of Ubuntu Precise has the same error (with the same guest machines).
I have not found any combination of guest settings which prevents this freeze yet. Even using the OSE edition of Virtualbox 4.1.12-UbuntuR7724S has the same error.
The probably-related VirtualBox bug ticket says it is fixed in VirtualBox source, and also details a workaround via grub.
The Debian bug is here.
Hopefully the patch will be applied to Ubuntu-12.04 .
(This answer is also at: https://askubuntu.com/questions/130726/win-7-virtual-box-vm-fails-to-start-after-upgrade-to-12-04 )
I can't be sure that I was having the same problem, but I also just upgraded from ubuntu 11.10 to 12.04 and attempting to boot my virtual machine (xp 32bit) would cause the host to freeze.
The fix was to do the following:
Enable absolute pointing device (almost certainly wasnt this that fixed it but hey ho!)
Enable VT-x/AMD-V acceleration and nested paging (found under settings->System->Acceleration)
Disable video acceleration (again dont think it was this but I don't fancy fiddling now it works)
Hope this works for you too.
I am using win7. I wish to use Fedora on my machine, but don't know just how much I will be needing either of my OS. I wish to install Ferdora and configure it as a dual boot system.
At the same time, when time calls for it, I want to run the same Fedora installation as a virtual machine on top of win7. Is there a way to do it?
VMWare Workstation supports this, but I've never tried in Windows.
Here's an article on their site (it discusses VMWare 5 and they're now on 7.1, so a newer one can probably be unearthed):
