--- Comment #2 from Arcadiy Ivanov (arca...@ivanov.biz) --- I'm saying: a. The intel_brightness values change, but the brightness doesn't except to turn off. a. The ACPI errors occur every time the brightness is changed via keyboard combo. I just edited brightness directly by writing to it - it didn't change, but ACPI errors also didn't appear. So the ACPI errors are artifacts of pressing the key combination. To answer your questions: 1. Kernel is 5.1.18-300.fc30.x86_64. I'll be trying the drm-tip for https://bugs.freedesktop.org/show_bug.cgi?id=111179 anyway. 2. Yes, but (a) it's not active as no NVidia Linux driver supports T2000 in 5540 (b) it's Bumblebee'd anyway, so the device is off. 3. I believe switchable graphics is ON but I'll recheck. 4. Any particular ACPI tables you want or all of them? -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
