Gnome disable screen power off on lockscreen

Hi, a quick tip today. To keep screen on while lockscreen is activated you must disable DPMS. do it by typing in console:

xset -dpms

Because this setting is only active during current session, you must put it to some startup script. I have my scripts in ~/.config

I use gnome-session-properties for configuring startup scripts. 

I even registered to gnome bugzilla to suggest this workaround. Strange, that all those Linux gurus didn't found out this solution, me, Windows guy, had to do it ;)

VCAP - DCA 5.5 thoughts

Today I took VCAP - DCA 5.5 exam. And I passed :)

So now I'm officially:

Few thoughts about this exam, maybe someone will find it usefull:

- Many people already mentioned that. Time is your worst enemy. I wasn't able to do few questions, because time ran out.
- Because of that, don't spend too much time on one question. Do whatever you can and move along.
- Pay attention to question and required servers you're supposed to work on.
- Expect typos in naming, questions. Be intelligent.
- There is no option to "mark" question for review at the end. So if you want to read questions from beggining of the exam, be ready to click "previous","previous","previous"... It takes time, which you don't have. So either remember things you have to do or write it down.
- Yeah, it's slow... connection I mean, don't freak out if you'll loose connection for a short while (happened to me).


Generally, if you have an experience you'll pass it. Just watch this timer....

Static teaming causes packet lost on HP BL460c gen 8 with virtual connect

A quickie today. We had problems with packet lost on Windows Server 2012 R2 servers. It turned out that Virtual Connect doesn't support "Static" and "LACP" teaming modes, only "Switch independent".

Changing teaming mode resolved our issue.
