To manage notifications about
That's a little too complex to explain here.
Instead please try booting Ubuntu 22.04 from USB to see if it has the same bug:
http://cdimage.ubuntu.com/daily-live/current/
If you are willing to also install 22.04, and the bug still isn't fixed
there, then the drm-tip kernel should install more
Can you help me out in installing the latest drmtip kernel.. Whenever I try to
install drmtip kernel it shows error like,
"linux-headers-***-generic depends on libc6(>= 2.34) however Version of libc6
on system is 2.31
Package libssl3 is not installed"
I think I will have to compile the latest
nomodeset really is a temporary workaround. It disables the GPU hardware
acceleration, and in some cases might prevent you from even getting the
correct screen resolution.

Ok I will try 'drmtip' kernel, and report it as well in case it's not
fixed.. But I would like to ask what if I use the "nomodeset"
parameter.. What compromises would be there in using nomodeset?

I don't think changing distro will fix it.
The final thing to try is the latest 'drmtip' kernel:
https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/
If the bug still isn't fixed in that latest kernel then you should
report it to the kernel graphics developers at:
Btw I am trying to install kernel 5.15.32.. Will let you know if things
change..

I would like to ask one more thing, Should I try some other liunx
distribution such as fedora or linux mint or something else that you can
suggest? Will changing the distro fix this issue? :(

If i use the nomodeset parameter what things would get disabled?
Will I get slow performance with nomodeset parameter?

My only remaining suggestions are:
* Try a newer kernel, or more simply try Ubuntu 22.04 which contains a
newer kernel: http://cdimage.ubuntu.com/daily-live/current/ ; or
* Use the nomodeset kernel parameter :(

Here is a screenshot of the grub file
Added parameter, updated the grub and rebooted but nothing has changed... The
flickering lines are still there
** Attachment added: "Screenshot from 2022-03-28 14-34-40.png"
Please try adding kernel parameter:
i915.enable_psr=0
which you can do in /etc/default/grub as part of the
GRUB_CMDLINE_LINUX_DEFAULT line. Then run:
sudo update-grub
and reboot.

So here's an update,
It seems like I don't have the 'Secure Boot' Option in my bios so I couldn't
test it.
I disabled UEFI devices from my bios and that forced it to use legacy boot
devices only (Sandisk Cruzer Blade in the above video is my bootable pendrive
from which I am installing ubuntu)
Ok I will try this just now and check the results.. Thanks for your
time..

In the past when people had trouble with HP all-in-one screens, the
solution was:
1. Beware! Backup you data! You will likely need to reinstall Ubuntu after
this.
2. Go into the BIOS and toggle the legacy mode/secure boot settings.
3. Reinstall Ubuntu.
