I have a Dell Latitude E6440 with a Radeon Graphics Card and do not want to disable Secure Boot.

How can I install the proper drivers for the Card without disabling Secure Boot?

I found some posts mentioning loading self created certificates into the kernel but no real instructions on how to do it.

lspci -nn | grep -E 'VGA|Display'
00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06)

  • If your BIOS or your graphics card does not support it that is never going to happen. Please provide details on both. Sometimes you can get it to work with a BIOS update. – Rinzwind Jan 30 '18 at 9:26
  • @Rinzwind I added the lscpi output, BIOS should be Up-to-date and using UEFI Boot. – FatalMerlin Jan 30 '18 at 9:33
