NVIDIA M60 / M6 Problems – check your card in “graphics” mode!

Virtually Visual

This blog only applies to M60 / M6 (Maxwell generation) GRID cards. It is not relevant to GRID 1.0 (K1/K2 cards).

Try this first!

If you are experiencing issues with a new M60 / M6 card, please run this command:

lspci –n | grep 10de

You should get something that looks like:

[root@SAGRID-ESXi5:~] lspci –n | grep 10de

0000:04:00.0 Class 0300: 10de:11bf [vmgfx2]

0000:05:00.0 Class 0300: 10de:11bf [vmgfx3]

0000:08:00.0 Class 0300: 10de:11bf [vmgfx0]

0000:09:00.0 Class 0300: 10de:11bf [vmgfx1]

0000:86:00.0 Class 0300: 10de:11bf [vmgfx4]

0000:87:00.0 Class 0300: 10de:11bf [vmgfx5]

If your system reports 0302 instead of 0300, the GPU is in “compute” mode. If it reports 0300 as above then it’s in “graphics” mode and this is not the cause of your issue.

If you notice the GPUs are in compute mode – then use the gpumodeswitch utility and change it to graphics, make sure you reboot the server to apply…

Click and Right click not working on Windows 10 Start Menu

Posted on Tuesday 12/04/2016 by Victor — 1 Comment

I found out the hard way, that by removing the AppX software packages that come pre-installed in Windows 10, the “immersive” shell might not work as supposed.

To be more precise, clicking and right-clicking the Start Menu will not do anything.

In order to solve this, all AppX packages will need to be reinstalled and the following command will fix the issue:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

VpxClient has stopped working

Posted on Monday 07/03/2016 by Victor — 8 Comments

1. Navigate to “C:\Program Files (x86)\VMware\Infrastructure\Virtual Infrastructure Client\Launcher”
2. Edit as Administrator VpxClient.exe.config (you can use Notepad++ and if the file editing operation requires Administrative permissions, Notepad++ will ask you to elevate permissions; cool tool!)
3. Add the following lines in a new line, prefferably after </appSettings>:

In the end, my advice is to move away from the vCenter Client and upgrade ESXi and vCenter 🙂

Announcement – VMware VSAN 6.2

Posted on Wednesday 10/02/2016 by Victor — Leave a comment

vcdx133.com

VMware Virtual SAN version 6.2 has been announced. Two big improvements are the inclusion of Data Integrity (checksum on write and read) and improved UI integration into the vSphere Web Client.

This is the fourth major release of VSAN functionality. VMware is definitely taking this product seriously and trying to evolve VSAN to a true enterprise-grade SDS stack.

If you are a customer that has an extensive investment in the VMware eco-system from a people, process and technology perspective, then VSAN could be a good choice if you are dipping your toes into the HCI space for a small part of your infrastructure. Use-cases such as Management, DMZ, PCI, Dev/Test and EUC Clusters are a great fit, in my opinion. If you are selecting an enterprise-wide solution for mission/business critical applications, then a more mature SDS vendor would be worth considering to minimise risk.

Citrix StoreFront authentication in SSO mode

Posted on Monday 08/02/2016 by Victor — Leave a comment

I found something extremely intriguing about StoreFront and authentication and wanted to share it with the community.

Let’s take StoreFront 3.0, although I bet it was there since beginning.

When StoreFront is configured in SSO mode you have two types of authentication:

From the Internet (via NetScaler)
From internal network (no NetScaler involved)

The Internet authentication is pretty straight forward. StoreFront SSO is not active and users must login the old way, with username and password.

The difference can be seen when SSO authentication from internal network is being used and one specific feature is missing. Explicitly.

And apparently, there’s a reason for it.

In StoreFront’s top-right side, there’s a drop-down menu that appears when clicking the user’s name. The drop-down menu is by default populated with the “Activate” and “Log Off ” options, but the Administrator can add more options there.

But where’s the “Change password…” option?

Well, I mentioned that this feature is explicitly removed when SSO is active, and the reason is very logic and I’d give lots of Kudos to Citrix for this.

The reason for the missing “Change password…” option is just one: SECURITY.

As mentioned by some friends at Citrix, the logic behind this is quite simple. When an user logs in to his computer and SSO is active, the option is missing in order to protect it’s password, as he might leave his PC unlocked and “a friend” could change the password from StoreFront. And because SSO is active, the “friend” would not be asked for the current password.

If you have like me, clients that need to change passwords from StoreFront, tell them to connect with the alternate login method (Username and Password) and the “Change password…” field will appear where it should be.

Cheers!

Remove “bloatware” AppX software from Windows 10

Posted on Thursday 14/01/2016 by Victor — 1 Comment

It’s pretty annoying for me to have bloatware on my computer and the embedded Windows 10 applications are for me, bloatware.

Why not to remove them? Well it’s not that easy as you need to click a lot.

So we need to remove it in a scripted way… Well… try running PowerShell as Administrator and type the code below, but beware, that YOU MIGHT actually use some of the apps I don’t, and want removed.

LATER UPDATE: As described in this post, removing the Windows 10 embedded AppX software packages, might break something inside Windows and clicking or right-clicking on the Start Menu will not work!

No right click on desktop after hiding desktop icons in Windows 10 build 10547

Posted on Sunday 13/12/2015 by Victor — Leave a comment

Hey folks,

Today I finally found a fix for a pesky issue that was annoying me for some weeks, but didn’t had the time to fix it.

So, apparently in Windows 10 build 10547 (Windows 10 Enterprise Insider Preview), if you right click your desktop and hide your desktop icons, (Desktop Right click > View > Show desktop icons) the icons will be hidden (as designed) but right click will not work anymore, so you will have no way to put them back on “GOTCHA!”

The right click function has a keyboard shortcut – Shift+F10. Press this combination and be amazed!

🙂

Joy to you all!

Redway 3D Watch demo on a RDP 8.1 session with Windows 2012 R2 and NVIDIA GRID

Posted on Tuesday 14/10/2014 by Victor — Leave a comment

I was very impressed that this is possible. I was trying to do a test with NVIDIA GRID in vDGA (passt-hrough) mode on a Windows Server 2012 R2 XenApp 7.5 and a vSphere 5.5 host with a GRID K2 core assigned.

This is a direct RDP connection from Windows 8.1 client to the server.
The performance is amazing for RDP but look at the bandwidth consumption and CPU. It doesn’t compare with HDX 3D Pro but still, it’s great to see it working!
