I got the dn2820fykh with BIOS version 015 installed.
I installed Ubuntu 14.04 on the machine and also installed software to be able to remotely connect to the machine.
Everything work fine, and the I decided to upgrade BIOS to latest version (034) and then it was no longer possible to remotely control the machine.
I can connect but I can not see anything on the desktop, just the background image.
I've tried two different remote control softwars with same result. Are there any bugs reported in this area?
I do realize Linux is not supported, but it seems like some Windows user have had similar problems.
Hi igo309, you may try rolling back with a BIOS recovery. It will probably work better if you do incremental BIOS updates; that is what we recommend instead of jumping many versions up to the latest one.
