4.20 mainline dmesg
sorry cant bisect even if i could it requires a lot of time,since it is graphical and the laptop uses only amd gpus,it is likely a commit to the amdgpu that caused it.
kernel 4.20rc5 completely broke on my laptop cannot boot or look at logs it freezes after grub with cursor blink and cpu fan at 100%
that was an issue with the kernel fedora mainline repo, kernel 4.20rc5 boots on my laptop on archlinux, but the mouse pointer issue remains
A workaround that works is to enable software cursor in Xorg,
i edited 10-amdgpu.conf and 10-radeon.conf
Option "SWCursor" "True"
Hello issue persists on latest kernel 4.20 stable
tried both wayland and xorg on kde
This issue also affects 2500U and 2700U, but not Vega 64.
bug exists in kernel 5.0rc1 too
There's a fix for this bug coming soon.
The bug only affects Raven systems and was a regression introduced in 4.20.
regression is still present at linux 4.20.3
Will show up in stable soon.
Finally!!! i applied the fix in kernel 4.20.3 and it works!!!thx i ve been waiting for a month for this
