Re: iMac upgrade 20.04 > 20.10 graphics driver issue
As I stated above I tried booting of both Groovy and the lastest Manjaro, both present me with a black screen on boot. (LiveUsb)
I didn't try safe graphics which seems to set NOMODESET upon starting.
On the Manjaro forums people seem to be experiencing this problem since the 5.7 kernel.
Re: iMac upgrade 20.04 > 20.10 graphics driver issue
I can boot again without having to set NOMODESET..... using 5.10 RC1 kernel!
Kernel 5.10 seems to fix the issue.
I did this:
Code:
mkdir kernel_5_10_RC_1
cd kernel_5_10_RC_1
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10-rc1/amd64/linux-headers-5.10.0-051000rc1_5.10.0-051000rc1.202010291359_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10-rc1/amd64/linux-headers-5.10.0-051000rc1-generic_5.10.0-051000rc1.202010291359_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10-rc1/amd64/linux-image-unsigned-5.10.0-051000rc1-generic_5.10.0-051000rc1.202010291359_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10-rc1/amd64/linux-modules-5.10.0-051000rc1-generic_5.10.0-051000rc1.202010291359_amd64.deb
sudo dpkg -i *.deb
reboot

Congrats! Installing an RC kernel is not for the faint of heart, but if it works for you, that's what counts. If you consider this matter solved, please mark it so by using the thread tools option in your first post and others can then benefit from their searches.
