I wonder if I can output 4k resolution (3840 × 2160) @ 30Hz with a Intel HD4000 graphics using Linux and a single HDMI output.
The best I've gotten is 18 Hz when I use "cvt -r 3840 2160 60" and change the pixel limit it gives to 165.00 and use xrandr. Anything higher and there is too much blinking of the screen.
I know that there is a problem with the pixel clock (which is limited to 165MHz) which limits the output maximal output power.
Where is the pixel clock limited? In the kernel? In the graphics driver? Can it be removed/fixed in general?submitted by milkywaymasta

I've enabled four ports in my iptables but when I run a port scanner against the box, it only shows two being open. 8834 and 22, 80 and 443 are not showing as open. Any thoughts?
[root@lab3 mnickel]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- anywhere anywhere tcp dpt:8834 DROP all -- anywhere anywheresubmitted by michaeln05

As with most cutting-edge gadgets these days, there's not much going on in the smart eyewear market that doesn't involve Android or Linux.
Preface: I have experience with Windows, Linux, VMware, and Virtualbox. But I am not anywhere close to an expert.
Goal: I want to dual boot my Windows 7 machine with a lightweight Linux OS that serves only as a host for a VM environment. So basically ESXi, but on a much smaller level.
Has anyone attempted this before? Is it possible to do on a consumer device level? Is there a linux distro that functions or can be made to function like ESXi? Is there a better alternative?
Edit: I should add a few details.
I want to boot into and access the VM from my machine, so it wouldn't be exactly like ESXi. I would want it to perform like a "VirtualBox OS" or "VMWare OS", that takes me directly to a list of VMs, I choose which one to boot, and it brings it up full screen. I have no reason to have a UI at any point before booting into the VM, so that all feels like overhead I don't want.submitted by handbra

I have been a Windows operating system user since i started computing, i would like to get some information on switching to Linux from Windows. I also have various questions like If you have to have emulators to run my .exe files, what would i have to prepare for and information general information that you would think helpful. Links are welcomed and thanks in advance.submitted by Endoresu
