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