Hi,

you are probably using an Intel GPU.

Latest Ubuntu flavours default to the "modesetting" driver. Maybe the
"intel" driver is dropped completely, I don't know.

The reason for this is, that the "intel" driver is unsupported and not
working on kernel > 5.something. Some kernels > 5.something are still
ok, but at some version you can't use it anymore with the "intel"
driver.

On Arch Linux I stay with 4.19 realtime patched LTS kernels and the
"intel" driver, because on my Intel GPU based machine the "modsetting"
driver is a PITA, with at least some software, at very least Firefox.

When using Ubuntu live media, I stay with the "modesetting" driver. I
still can use Firefox, just the performance of Firefox is less good,
when using an Ubuntu live media.

Sorry, I don't want to search for links, but at least you now have got
some keywords, you could use to do some research on your own, assuming
you are on an Intel machine.

Regards,
Ralf
