Bug ID: 68471
Summary: Display extremely dark on Dell XPS 13 since 3.10
Kernel in EFI mode
Product: Drivers
Version: 2.5
Kernel Version: 3.13.0-0.rc7.git3.1.fc21.x86_64
Hardware: All
OS: Linux
Tree: Fedora
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - Intel)
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: dennisml at conversis.de
CC: intel-gfx-bugs at lists.freedesktop.org
Regression: No
Any kernel >= 3.10 results in the display ending up extremely dark and
brightness cannot be change using the keys when booting using UEFI.
After doing some research it seems there are various backlight issues but I'm
not sure which issue exactly I'm dealing with here and what to do about it.
Right now I cannot update my kernel or upgrade my distribution because of this.
