Comment 3 for bug 1950088

According to Apple Mac OS X info this hardware is as follows:

MacBook Pro (15-inch, Mid 2010)
CPU: 2.53 GHz Intel Core i5
RAM: 4 GB 1067 MHz DDR3
GPU: Intel HD Graphics, 288 MB

The hardware *also* has NVIDIA GeForce GT 330M connected (according to OS X self-diagnostics) via 16x PCIe and it has 256 MB of RAM (Mac OS X cannot tell if this is dedicated RAM or part of system RAM like with integrated intel graphics).

I believe that the OS X automaticaly switches between these GPUs according to system needs. I would guess that this is also tried by Jammy livecd and it hangs. I guess for this old hardware, automatically turning off the NVIDIA GPU and using just the Intel Graphics could be a good option if the switching is not stable.

According to /proc/cpuinfo the Linux kernel successfully run the CPU up to 3.1 GHz so CPU frequency control did work absolutely fine.

All the above tests were done with jammy nightly build from date 2021-11-05 obtained here: http://cdimage.ubuntu.com/ubuntukylin/daily-live/current/ and I did write the ISO image to USB memory stick using Ubuntu "Startup Disk Creator" software. I know that some newer MacBooks no longer support booting from USB memory simply by holding down ALT while booting the computer but for this hardware that still appears to work just fine.
