I am getting started with Cloudera Hadoop and downloaded the VMWare image from here. While the image itself works fine, my mouse does not.
I am running on a new MacBookAir, using VMWare for the Mac. I created the image using the uncompressed image file, but was unsure which OS to select in VMWare. I tried both Mac OS (which didn't even boot in the VM) and then Windows OS (which did boot).
The mouse behaves as follows in the VM. Right click works fine, i.e. context-menu appears. Left click does nothing. I have tried to use the 'mouse' system setting to fix this, but that doesn't change anything.
Suggestions?
I got it working - a couple of things. First I needed to re-create the VM using the correct OS (it is Linux - CentOS 5.8, and in my case 64-bit).
Next I needed to mount a CD drive (had to force shutdown and then re-start) via the Settings. After that I had to install the VMWare Tools via the newly mounted CD (from the original source media).
After that I had to do a cold restart one more time, then voila - mouse is working ok.

I am trying to get a GUI running on an AWS Centos 7 instance. Tiger vnc seems to run fine and I can get connected with the tigervnc viewer. However, all I get is a grey screen with 4 checkboxes in the upper right hand corner.
I installed Gnome and Server with GUI and I have tried changing my xstartup a hundred different ways, but I always get a grey screen. See the screenshot.
How can I get the gnome gui to work over my vnc session?
thanks
I found out that you will get this issue when using cPanel and WHM if you have the user in a jailed root. Open up the access and the full OS will load.
I would imagine that there is some way to work around this to keep a jailed root, but I am not a linux guru, so I don't know how to accomplish that.
I had built console core image for raspberry Pi3, and I am able to boot the Rpi3 successfully using SD card.
I have created an electron app which is able to launch on remote display over ssh.
However when I launch the application on Monitor connected through HDMI Cable, It gives following error
Can not open Display :0.0
I have seen many people asking this question for not able to launch on remote display, which works fine in my case.
Can anyone help in this?
With console core, you don't have an X server running to display on.
You can upgrade your system to include the X installation -- search for 'install pixel desktop' -- or you could just refresh the card with the lite or full image.
If you set the Pi to auto login to the pi account, you can start your application on login by adding it to the bottom of .xinitrc. You could also start it from a remote ssh, displaying on the local display, by setting DISPLAY=:0 in the environment before you start. You'll need to explore the world of X Windows authentication to make this work. See the man page for the xhost command, for instance.
(This is an expansion of LetoThe2nd's comment, which probably should have been an answer instead.)
Console core image means that there is no xserver running, and hence no display :0. Try getting started with core-image-x11 maybe, or whatever suits the RasPi.
I'm using ORACLE Virtualbox in my Mac, I get two problems when running a VM
The Display is shrunk, it doesn't occupy the complete screen even at Full Screen Mode.
When mouse is captured in the VM I'm unable to move it out of VM, when I'm not in Full Screen Mode.
I'm not sure why this happens
I toggled into full screen mode on QGIS 2.2 on my Mac, and now the menu bar won't show and I can't toggle out of it. From the documentation, it looks like it should toggle with F11, but it's not working. I've seen people having similar trouble on Ubuntu and Windows 7, but nothing for OSX. Any ideas? I appreciate it.
Just spent close to an hour with this problem- QGIS 2.2 on mavericks. Really vexing! I tried reinstalling (after trashing the previous version as instructed in the install notes), tried removing the hidden .qgis2 folder in the home directory, tried disabling all spaces on the machine (I started with 8 desktops), tried all permutations of Apple-F, ctrl-F, apple-shift-F, etc...
Finally, and simply, the answer was this:
F11 is documented as the toggle key, but in my mostly stock setup this was bound in MissionControl to 'display the desktop'. I rebound that function to F1, and then with QGIS up, hit F11 (on my MBP I need to also hold the fn key otherwise it's 'volume down') and I was out of Full screen mode.
Hope it works for you!
I have accidentally deleted the file System/Library/Extensions/IOStorageFamily.kext by mistake. I know how stupid this was!
Now my iMac (model 2008, running Mavericks) gets stuck on the grey startup screen and hangs forever after the Apple logo turns into a no entry sign whilst the wheel continues to turn forever, see the following link for image showing this screen:
No entry sign on startup screen
I have run Disk Utility from the install CD and repaired the disk permissions with no success.
I have tried to run the rescue partition by using the Command + R key but this just displays my exsisting HD and does not show another option.
I have tried to boot into single user start with no success. The screen eventually hangs and says it can not find IOStorageFamily.kext.
I have tried to boot into safe mode with no success. It simply fails with the no entry sign as above.
I have reset the PRAM but this did not make any difference.
I have done a hardware test using the D key on startup but this returned no errors.
Please can someone advise if there is any way to fix this problem and if the is then what is the best way to do it? I know that it is not a harddrive failing or anything else and is simply because I accidently deleted the IOStorageFamily.kext file. Surely there is a way to repair this?
I appreciate any help or advice.
Many thanks
I have managed to fix the problem by using the following method:
http://support.apple.com/kb/PH13842
It says:
If you have two Mac computers with FireWire or Thunderbolt ports, you
can connect them so that one of them appears as an external hard disk
on the other. This is called “target disk mode.”
Connect the two computers with a FireWire or Thunderbolt cable. Start
up the computer to be used as a disk in target disk mode: If the
computer is off, start it up while holding down the T key.
If the computer is on, choose Apple menu > System Preferences, click
Startup Disk, then click Target Disk Mode.
When the computer has started up, a disk icon appears on the desktop
of the other computer.
Transfer files by dragging them to and from the disk. Eject the disk
by dragging its icon to the Trash. While you drag, the Trash icon
changes to an Eject icon.
On the computer you used as a disk, push the power button to shut it
down, then disconnect the cable.
After connecting to another Mac I simply copied the deleted file back into the correct directory from the host Mac.
I then booted my Mac successfully and repaired the file permissions via Disk Utility.
