Hello, upgraded from ubuntu 23.10 to 24.04, when at the first time I saw flickering.
some attempts: 1) sudo gedit /etc/modprobe.d/i915.conf options i915 enable_psr=1 (0 value was what I found there) 2) sudo gedit /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=guided quiet splash options i915 enable_psr=0" this resulted in unknown parameter: 3) sudo gedit /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=guided quiet splash options i915.enable_rc6" this is what (it seems up to now that) worked: 4) sudo gedit /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=guided quiet splash intel_idle.max_cstate=1" for attempts 2-4 grub was updated and then rebooted.
