Summary: Framebuffer on boot causes brightness to go to minimum
on HP laptop
Product: Drivers
Version: 2.5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: low
Priority: P1
Component: Video(DRI - Intel)
AssignedTo: intel-gfx-bugs at lists.freedesktop.org
ReportedBy: dandart at googlemail.com
CC: intel-gfx-bugs at lists.freedesktop.org
Regression: No
Hi, FYI:
On my Pavilion G6 going into framebuffer causes the screen to dim to lowest
brightness setting.
I can manually increase it after this time using the buttons if I install the
modules (which all distros bundle).
Caused when going into framebuffer for the first time on boot.
Resolves itself sometimes when going into X.
product: HP Pavilion g6 Notebook PC (A9W47EA#ABU)

bus info: pci at 0000:00:02.0
version: 09
width: 64 bits
clock: 33MHz
capabilities: msi pm vga_controller bus_master cap_list rom
configuration: driver=i915 latency=0
resources: irq:42 memory:c0000000-c03fffff
memory:b0000000-bfffffff ioport:4000(size=64)
Not a regression afaik as I've always noticed it.
Low priority as easily worked around (just confusing why it happens).
Happens on any kernel (ubuntu, debian, homebuilt up to 3.6 - not tested on
3.7+).
Cheers
