Problem with Optiplex 9010 and linux kernel

[lorenzo33]

Hello,

Recently, I deployed Porteus-Kiosk on a PXE Infrastructure. I'm using the last version (3.1.1) with the kernel version 3.12.20.
The solution works perfectly on most computers but we encounter a display problem with dell optiplex 9010 all in one (flickering screen).

I found a solution on the ubuntu's forum that advises to update the linux kernel to version 3.15. I applied solution on a Unbuntu 14.04.1 distribution and the It works perfectly.

I want to know how to update linux kernel Porteus-Kiosk but i not found solution on the forum.

Please Help me.

Lorenzo

hi Lorenzo,

kiosk security depends strictly on the kernel config and version used in kiosk and i'm the only person who can perform it's upgrades or downgrades. this is the only component which can not be replaced by the users. even if you manage to do it yourself (it's not that easy as one may think - you have to upgrade firmware and initrdpxe.xz component) then kiosk will boot into default/unconfigured state.
kernel takes a part into our server authorization process and protects the profiles of customers who signed to the 'automatic updates' service.
in short - i'm the only person who can replace it in kiosk.

if you want to use Porteus Kiosk on Optiplex 9010 then you have no other choices than:
- subscribe to 'automatic updates' which provides kernel upgrades every month (last kernel version in 'automatic updates' channel is 3.14.18):
http://porteus-kiosk.org/automatic-updates.html

- buy custom kiosk build (kernel can be bumped to any version - even to 3.16.x):
http://porteus-kiosk.org/builds.html

EDIT:\\
forgot to mention:
kiosk offers now 3 months free trial for the 'automatic updates' service:
http://porteus-kiosk.org/news.html#140829
so maybe we could sign one of your Optiplex 9010 PCs and check if an upgrade resolves the problem automatically?
that check would cost nothing on your side.

thanks

Unfortunatly, update of porteus-kiosk doesn't work with the linux kernel 3.14.18.

Anybody have some idea ?
