Hi Hui Wang. I'm on a -28 kernel. Did what you said to install the -26
v4 kernel. As usual, comment out "options snd-intel-dspcfg
dsp_driver=1". Use my Hdmi.conf. When I rebooted with the -26 v4 kernel,
I got stuck at a black screen again. But this time, I decided to try it
a couple of times. It tu
please install a higher version kernel like 5.4.0-28/29 first, boot with
the new kernel, then sudo dpkg -r --force-all linux-image-
unsigned-5.4.0-26-generic, install the v4 testing kernel to do the test.
I installed the v4 testing kernel on my machine, there is no errors:
hwang4@hwang4-Vostro-5
Sorry. How should I start installing the v4 kernel? I just downloaded
and did "sudo dpkg -i *.deb". But I got "errors encountered installing..
(the kernel)".
Do I have to do " sudo dpkg -r --force-all (something here)" first? Also
what will happen to the original -26 kernel?

This is the testing kernel based on the -26 kernel:
https://people.canonical.com/~hwang4/25skipi915/v4/
And don't forget the Hdmi.conf if kernel has no obvious errors or failures on
audio.

I don't know that.
Maybe there is some necessary fixup in the -26 kernel but not in the
-25 kernel. After the -27 is ready, I will build a testing kernel based
on -26 kernel, then you could test -26 testing kernel, if it has boot
issues, you could choose the -27 kernel to boot then.
