> > Also, another issue, I have pluymouth enabled with FRAMEBUFFER=y. After using the gmux patches, the size of the theme has become too tiny for an initial few seconds, then it gets normal. I tested this by compiling a kernel without these patches, and the bug got fixed. I also tried using acpi backlight using command line (that made me discover the `acpi_backlight=video` not working bug). Is that also related to some upstream bug? Hi Hans It turns out that Apple-gmux had to be loaded in the initramfs for Plymouth to work properly. So, it actually was my mistake. Also I noticed that the respond to your patch for me to test didn’t reach since it was an HTML email. So, yes, your patch honours `acpi_backlight=video`
