tried this but fail : https://serverfault.com/questions/531269/linux-drivers-for-dell-poweredge-server
it seems dell is not really friendly to fedora
@scottalanmiller help
I looked at the results there. ServerFault doesn't seem to know servers very well, their top response was less than stellar. That wouldn't have flown around here.

What do you need the display driver for?
What exactly are you installing that isn't Fedora 26 "Minimal" or "Fedora Server Edition"?
I know if you do install a GUI on a server, Cinnamon is a bad choice. Gnome or XFCE would work better.
This ^^^
Servers don't need display drivers. There is a good reason why Dell doesn't put any energy into this.

Can you run virt-manager from a Linux desktop and connect to your 720 that way?
Even from just a VM on top of Windows or something. Doesn't need to be a dedicated Linux workstation.

@kuyaz said in Dell R720 Display problem with Fedora 26 server:
I have problem with starting the Linux desktop. it seems the display is not set properly.
still figuring how to set the display properly in x11.Why are you using X11 on fedora 26? Wayland is the default.

@francesco-provino i assumae your idrac is enterprise license? mine is express only
sad... haha...
official price of the idrac enterprise license is 400$ ++ .... -.-This is a reason to use SuperMicro. That stuff is free.

thanks.Will continue my experiment. I guess I stuck with PERC RAID then.
Or blessed with, as is more commonly the case.

@francesco-provino do you know how to bypass the HW RAID in DELL R720?
I want to use SW raid instead with MD.Thanks.
Why do you want to bypass the PERC controller?

He wanted to experiment with software raid in a test lab bit everyone said no as if hes doing it in production...

PERC will cause some issues with that. Each drive will be individual RAID 0.

Some PERCs do passthrough. I've done it bit I forget which one. Just look it up.
But doing RAID 0s will still work. I wouldn't do it in production though.

Works for some things, like making an array. Doesn't work for others, like monitoring an array. Arguably, the later is more important.

@tim_g yes, it is PERC 3xx which can be set to IT mode if I read it correctly.

Oh, you have this?

No, I dont have that unit. I just came across article online and someone manage to IT mode H310.
You looking for the unit for testing? will bump you if i find it. -

You looking for the unit for testing? will bump you if i find it.You're looking for HBA mode (pass-through). The PERC H730 does it, but there was another on I used... it's just I forget which one. I want to say H700 or H710, but I'd have to wait until tomorrow sometime to check.
-
Maybe it was the H310... I'll check tomorrow.
-
H310 is not meant to be a RAID controller, it might do passthrough well.
