So, the root of my booting problem is Linux doesn’t yet fully support my |
| 2 |
intel core i5-10400 processor’s uhd 630 graphics. |
| 3 |
|
| 4 |
I’ve been able to boot gentoo-sources-5.10.27 successfully using grub on my |
| 5 |
new Asus Tuf Gaming B560M-Plus Wifi board equipped with an intel core |
| 6 |
i5-10400 processor. |

If you use the nomodeset kernel parameter, the boot messages scrolling by |
| 9 |
on the screen look like what you’d expect from a normal grub/gentoo boot. |
| 10 |
|
| 11 |
If you don’t use nomodeset, a few initial lines of boot progress appear |
| 12 |
from grub, then stop. It looks like the boot has hung after the initrd, |
| 13 |
but it hasn’t. When the kernel takes over the display, something in the |
| 14 |
modesetting goes wrong, and nothing is displayed from that point on. But |
| 15 |
the system boots fine otherwise. |
| 16 |
|
| 17 |
You can’t start X11 even after following the instructions in |
| 18 |
https://wiki.gentoo.org/wiki/Xorg/Guide. The Xorg log indicates that it |
| 19 |
can’t find the proper driver. |
| 20 |
|
| 21 |
After searching for the errors reported in the Xorg log, I stumbled on the |
| 22 |
same problem I’m having in |
| 23 |
https://unix.stackexchange.com/questions/642535/xorg-detects-no-displays-with-an-intel-uhd-630. |
| 24 |
That article in turn refers to activity in |
| 25 |
https://cgit.freedesktop.org/drm-tip, which is the direct rendering manager |
| 26 |
development site. What I gather from poking around there is that the intel |
| 27 |
915 video driver has just been patched to solve the problem I’m having, but |
| 28 |
uncertain whether the patch has made it out to the linux distros. The |
| 29 |
problem affects all intel processors with onboard uhd 630 graphics. |
| 30 |
|
| 31 |
I’ve tried gentoo-sources 5.10.27 and 5.11.21. Both have the video |
| 32 |
problem. I’ve also tried 5.12.4. Can’t get it to boot. Have also tried |
| 33 |
Ubuntu-20.04.2.0-desktop. It works fine on my older intel boxes, but |
| 34 |
displays the same video problem on my new board/cpu. Haven’t verified it, |
| 35 |
but guessing none of these have the uhd 630 patch. |
| 36 |
|
| 37 |
So, my previous suspects - secure boot, motherboard, grub, and my |
| 38 |
customized kernel configs - are all innocent and working fine. Just have |
| 39 |
to wait for the patched intel driver to show up in gentoo-sources. |
| 40 |
|
| 41 |
Thanks for all the helpful advice I received! Couldn’t have gotten this |
| 42 |
far without it. |
