Hi everyone,
I have a Dell Latitude 5480 laptop (i5 7440HQ with GeForce 930MX) with Fedora 41 installed.
When the laptop is idle for some time, the screen turns off and the laptop locks up. When I wake it up, the screen backlight starts flickering heavily and gradually goes away after about 10-15 minutes.
This happens especially when running on battery power.
Maybe someone has encountered this and can tell me where to dig?
I have already Nvidia drivers installed. In my GRUB configs I have:
GRUB_CMDLINE_LINUX_DEFAULT="quiet rhgb i915.enable_psr=0 i915.enable_rc6=0 i915.enable_fbc=0 nvidia-drm.modeset=1 nvidia-drm.fbdev=1”
GRUB_CMDLINE_LINUX=“modeprobe.blacklist=nouveau nvidia.NVreg_EnableGpuFirmware=0 nvidia.NVreg_PreserveVideoMemoryAllocations=1””
Here is some info about the GPUs and drivers:
root@latitude-lin:/mnt/data# lspci -k | grep -EA3 'VGA|3D|Display'
