Hello again,
I eventually have the i915/Intel HD4000 work along the 3.8 kernel: one
must pass "i915.invert_brightness=1" kernel parameter
# lspci -vvv -nn -s 00:02.0
00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core
processor Graphics Controller [8086:0166] (rev 09) (prog-if 00 [VGA controller])
Subsystem: Dell Device [1028:0589]
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B- DisINTx+
Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort-
<MAbort- >SERR- <PERR- INTx-
Latency: 0
Interrupt: pin A routed to IRQ 44
Region 0: Memory at c0000000 (64-bit, non-prefetchable) [size=4M]
Region 2: Memory at b0000000 (64-bit, prefetchable) [size=256M]
Region 4: I/O ports at 2000 [size=64]
Expansion ROM at <unassigned> [disabled]
Capabilities: <access denied>
Kernel driver in use: i915
Kernel modules: i915
As for the Cypress Trackpad, it got even worse: it is now recognised a
"ImPS/2 Generic Wheel Mouse", which is a regression compared to Quantal
3.5 Kernel:
# xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Atmel Atmel maXTouch Digitizer id=9 [slave pointer (2)]
⎜ ↳ ImPS/2 Generic Wheel Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
[...]
