Hello All,

I have been noticing lately that when I increase my laptop's brightness with the keyboard (Fn + Brightness Up), it lags. the more I increase in one go, the more it lags or even freezes for 30 seconds. Like, it takes about 20-30 seconds to get back to normal.

However, this does not happen when I decrease the brightness.. it gets decreased easily.

I am trying to find solution online but no luck. I did get close to similar problem but now I cant seem to find that article/forum.

Please help me fix this issue.

Here are the details; Linux ubuntu 5.19.0-35-generic #36~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Feb 17 15:17:25 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
Thank you.
