[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #30 from [email protected] --- I can confirm this bug with a Precision 5540 with vanilla 5.4.11. In kernel 5.1.x I was able to adjust my backlight by poking intel_backlight in sysfs. After updating to 5.3.x I lost this ability. I believe there is a regression here. The ACPI messages appear to be an independent issue from the backlight control issue. I've always gotten the ACPI messages, even when backlight control used to work correctly. I have tried building a kernel with CONFIG_ACPI_CUSTOM_METHOD and following Zhang's instructions. There was no change in behavior. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
