#2675: Backlight turned off on Radeon Mobility X600 ---------------------------------------+--------------------------- Reporter: leavengood | Owner: euan Type: bug | Status: in-progress Priority: normal | Milestone: R1 Component: Drivers/Graphics/radeon | Version: R1/pre-alpha1 Resolution: | Keywords: Blocked By: | Blocking: 7662 Has a Patch: 0 | Platform: All ---------------------------------------+--------------------------- Comment (by euan): after the radeon hd docs where release a lot of info about the past cards could be deduced. One place in particular to look is the BIOS_x_SCRATCH (x = 0 to 8). Have a look at RADEONInitBIOSRegisters() in xf86-video-ati here: http://cgit.freedesktop.org/xorg/driver/xf86-video- ati/tree/src/radeon_driver.c I'm sure I made patches, or versions that used the latest info on the scratch regs, but not sure if I got feedback or not. I still don't rule out ACPI integration in the laptop though either. Though I never gained the knowledge to be able to rule it out or not. -- Ticket URL: <http://dev.haiku-os.org/ticket/2675#comment:7> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
