#StackBounty: #boot #drivers #intel-graphics #21.04 No driver Intel iRIS xe under Ubuntu 21.04

Bounty: 50

Since I have make the new Ubuntu update, I have a black screen when I start my HP laptop (11th Gen Intel® Core™ i7-1165G7 @ 2.80GHz × 8 ) with a Intel iRIS xe GPU.

The only solution that I have find until now to work with my laptop is to put the "nomodeset" command in the grub but with this option, linux don’t used the Intel vendor driver and the driver that I can see in my config is a "llvmpipe (LLVM 12.0.0, 256 bits)"

I have reinstall my laptop one time with Secure Boot and one time without but I have always the same issue. I have try other solution like the "oibaf" drivers but always the same issue.

Here are info :

Without this drivers, I can’t change the brighthess of my screen and everybody is a little bit to dark for me 🙂
