Investigating Display Stability Issues on Intel Tiger Lake (HP 15t-dy200) PART -1

Laptop: HP Laptop 15t-dy200  
Core i7  
Graphics card: Intel Iris Xe Graphics. TGL GT2

Where it started:
Windows 11 suddenly showed a blank screen after logging in. I had to force shutdown. 
This happened multiple times, and refused to be fixed.

ATTEMPT 1: Reinstalling Windows. 

Issue: Windows 11 installer can't detect drives and partition

The hard disk didn't show up while installation of windows

✅Fix: Install RST driver

Steps:

1. Go to intel official website and download Intel Rapid Storage Technology Driver.
   [https://www.intel.com/content/www/us/en/download/19512/intel-rapid-storage-technology-driver-installation-software-with-intel-optane-memory-10th-and-11th-gen-platforms.html]

2. Extract the driver

   • open cmd locate downloaded RST.exe file on cmd (named SetupRST.exe)
   • extract .exe file contents into a folder cd dir_name
   • locate the VMD folder `SetupRST.exe -extractdrivers RST

3. Copy VMD folder to the Bootable Windows 11 USB (main folder)

4. When asked for drivers, select 'Load Drivers >> Browse' and browse to VMD folder

5. Select the 1st driver (Intel RST VMD Controller)

6. Now the partitions should appear 

7. Select partition and install driver

This worked until the wifi wasn't switched on. 

After switching on wifi, due to auto-updates happening, it would crash again....

ATTEMPT 2: Installing Ubuntu 24.04

Issues: while installing, the screen flickered after installing, screen still flickered a lot.

Fix: switching off panel screen refresh, and preventing it from entering deep power saving modes. 

Steps:

1) enter grub
sudo nano /etc/default/grub

2) change the line: 
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=1 intel_idle.max_cstate=1"

3) ctrl + o → save

4) ctrl + x → exit

5) updating grub
sudo update-grub

6) reboot system
sudo reboot

Issue: while doing this, i had formatted and changed the partition and overwritten windows 11 with Ubuntu. 

This leads to space issues in the future when i try installing Windows again.

Also, all drives were now in Ubuntu format.. not the FAT nor NTFS as required by Windows

may be because of the fact that Iris XE graphics is not supported as much anymore. but we don't know.

Note:
This issue has not been solved yet. Further additions will be added as I discover more about this issue.
