CentOS

Hello,

I purchased a Sumsung 32" 3840x2160 monitor and a gigabyte graphics card because my onboard graphics didn't support 3840x2160.
The graphic card is Gigabyte GT710 pcie x 8. I changed the cmos settings to auto detect the graphics card and configured it for pcie x 8.
With the hdmi cable plugged into the graphics card. The bios screens work fine. When I try to boot I get the screen to select the kernel to boot. But I never get the question to enter the encryption pass phase. Would a reinstall help?

The funny thing is when I change the cable to the onboard graphics I don't get the screen to select the kernel but get the question for the encryption pass phase. Upon entering the pass phase, it boots up normally.

I have a gigabyte motherboard which is 8 years old and i5 CPU.

Hello,

UPDATE: There was no question to input the encryption pass phase, but I guessed it was waiting for the pass phase, so I input the pass phase and was able to boot. Everything looks normal, so I guess my answer to "do I need to reinstall" is no.

Thanks for coming back and letting us know. I'll mark the thread as [SOLVED].

I think the problem is with plymouth, which is the application responsible for showing the graphical boot and asking for the encryption password.

Its installed by default, so one of the hundreds of packages that I always delete is plymouth. You can remove it with:
Once that is removed, you should see the normal text password prompt.

Sounds like you have two monitors and half the output is appearing on each...

Hi Trevor,

Good tip! I changed the BIOS monitor setting from auto to force use of graphics card. Now I get prompted for the encryption pass phase.
Thanks
