Even using the maximum brightness, it is much darker than previous (3.9.x kernel) darkest setting. In /sys/class/backlight/intel_backlight "cat max_brightness" gives "15625", trying to set "brightness" to a higher value results in "write error: Invalid argument". Additionally, setting a too small value results in a black display. Reproducible: Always No other package was updated. lspci -qbkvt -nn -[0000:00]-+-00.0 Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub [8086:27a0] +-02.0 Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] +-02.1 Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller [8086:27a6] +-1b.0 Intel Corporation NM10/ICH7 Family High Definition Audio Controller [8086:27d8] +-1c.0-[02]----00.0 Marvell Technology Group Ltd. 88E8055 PCI-E Gigabit Ethernet Controller [11ab:4363] +-1c.1-[03-04]-- +-1c.2-[05]----00.0 Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] +-1d.0 Intel Corporation NM10/ICH7 Family USB UHCI Controller #1 [8086:27c8] +-1d.1 Intel Corporation NM10/ICH7 Family USB UHCI Controller #2 [8086:27c9] +-1d.2 Intel Corporation NM10/ICH7 Family USB UHCI Controller #3 [8086:27ca] +-1d.3 Intel Corporation NM10/ICH7 Family USB UHCI Controller #4 [8086:27cb] +-1d.7 Intel Corporation NM10/ICH7 Family USB2 EHCI Controller [8086:27cc] +-1e.0-[08-10]--+-03.0 O2 Micro, Inc.
