Hello o/
I have an old potato laptop in which I installed Lubuntu 23.10 deleting everything else (I selected the delete disk option when installing it). It turns on and off fine but a screen appears for some seconds with the following warnings (from kern.log):
Code:
2024-04-11T20:51:07.662130+02:00 aspire kernel: [ 4.406799] UBSAN: array-index-out-of-bounds in /build/linux-D15vQj/linux-6.5.0/drivers/gpu/drm/radeon/radeon_atombios.c:2715:55

After searching these errors, I found multiple threads. One said that downgrading the kernel version was needed because it wasn't compatible with old specs, while another thread said that and update was probably needed. What should I do and what commands should I execute if necessary? (all packages from apt are up-to-date)
