I’ve been switching between NVIDIA 570.124.04 and 570.86.16 and choosing between kernels 6.4.0-150600.23.42-default and 6.4.0-150600.23.38-default with GRUB to collect data to report. I have not been able to consistently reproduce the problem.
kernel switch with previous driver installed:
kernel 23.42 NVIDIA 570.86.16 installed —> no graphics mode, inxi -G
reports 570.86.16 as driver
shutdown now
boot
kernel 23.38 NVIDIA 570.86.16 installed —> graphics mode, inxi -G
reports 570.86.16 as driver
With newer driver installed:
kernel 23.42 NVIDIA 570.124.04 installed —> graphics mode, but second monitor says signal is bad with fD: 312.3Mhz, fH: 39.5kHz, fV: 59.9Hz, inxi -G
reports 570.124.04 as driver
kernel 23.38 NVIDIA 570.124.04 installed —> hangs
But then:
shutdown now
boot
kernel 23.42 NVIDIA 570.124.04 installed —> graphics mode, but second monitor says signal is bad with fD: 312.3Mhz, fH: 39.5kHz, fV: 59.9Hz, inxi -G
reports 570.124.04 as driver
shutdown now
boot
kernel 23.42 NVIDIA 570.124.04 installed —> graphics mode, working
shutdown now, waited 30 min
boot
kernel 23.42 NVIDIA 570.124.04 installed —> graphics mode, but second monitor says signal is bad with fD: 312.3Mhz, fH: 39.5kHz, fV: 59.9Hz, inxi -G
reports 570.124.04 as driver
shutdown now
boot
kernel 23.42 NVIDIA 570.124.04 installed —> graphics mode, with second monitor is blank but no bad signal error, inxi -G
reports 570.124.04 as driver
shutdown now
boot
kernel 23.42 NVIDIA 570.124.04 installed —> graphics mode, working
So, after a cold boot, it seems to take more boots to get to a working state with the latest kernel and NVIDIA driver. Could it be a thermal issue, like the NVIDIA T600 graphics card needs to warm up? Is this worth bug reporting? Or more likely a hardware issue, versus a software one?
