| |
Hello all,
Somewhere between v3.6.8 [vanilla] and 3.7.0-rc7 the ability to control the LCD brightness was broken on this laptop [details below]. Basically it locks the brightness as full brightness and cannot be changed. It works properly in v3.6.8 though [and below...].
Details:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Dell Device 056e Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at c3000000 (64-bit, non-prefetchable) [size=4M] Memory at b0000000 (64-bit, prefetchable) [size=256M] I/O ports at 5000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [a4] PCI Advanced Features Kernel driver in use: i915
This is on a Dell Vostro 3560/0C05GV
I have the discrete radeon turned off [via vgaswitcheroo]. I have dell_wmi and dell_laptop loaded. I use the same kernel config between the two builds.
Tom
