switching between graphic drivers (Intel & Radeon)

I would like to use my Radeon GPU for ever. I have followed these steps. But seems it's not working for me. Here is the output of lspci after doing that steps:

$ lspci -nnk | egrep -i --color 'vga|3d|2d' -A3 | grep 'in use'
    Kernel driver in use: i915

What i tried is:

for configuring SWITCHEROO, I replaced GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=1" in /etc/default/grub.

And after that I ran these commands:

$ sudo update-grub
$ sudo su
# sudo echo DIS > /sys/kernel/debug/vgaswitcheroo/switch
# reboot

but after rebooting and checking lspci. I saw that current kernel driver in use is still i915 which is my Intel HD Graphic!

I'm sure that SWITCHEROO is configured correctly (Based on the docs).

Edit:

I have a laptop with hybrid graphics (Asus R540). which has a Intel HD Graphics 620 and a Radeon HD 8550M / R5 M230.

here is the full output of lspci -k:

What is the GPU model that you have? Do you have a laptop with hybrid graphics or is this a desktop computer with a truly dedicated GPU? Please edit your question and include more details about your hardware so that we can understand the problem more completely.

Hybrid graphics laptops often need to have the GPU enabled/disabled in firmware. Have you checked with the documentation for your laptop to make sure that the GPU is enabled? If it is disabled at the firmware level, Ubuntu won't be able to use it.

What version of Ubuntu are you using? Are there any BIOS updates available for your device?

I'm using Ubuntu 21.10. And please don't ake me about updating BIOS. Because I updated the BIOS once and because other versions of the BIOS were not compatible with my laptop, my laptop did not turn on and I had to reinstall the default BIOS from the motherboard.

Well you **never** use a BIOS for a different model. You should **always** follow the manufacturers directions to flash a BIOS and don't interrupt a BIOS flash. You are very lucky that you did not brick your board. In any case, your device may require an updated BIOS for hardware compatibility. If there is a BIOS update available for your model then you should update. Make sure you download the correct file for your exact model and follow their instructions carefully and completely

So do you think the only way to fix this issue is updating BIOS? Is there no less risky way?

It's not risky if you obtain the correct file and follow the instructions. If your BIOS is outdated and you are having problems hardware detection or compatibility, then you should update it

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
