#8457: Blank screen after boot on Radeon Mobility 4670 HD ------------------------------------------+---------------------------- Reporter: kvark | Owner: kallisti5 Type: bug | Status: new Priority: normal | Milestone: R1 Component: Drivers/Graphics/radeon_hd | Version: R1/Development Resolution: | Keywords: blank radeon Blocked By: | Blocking: Has a Patch: 0 | Platform: x86 ------------------------------------------+---------------------------- Comment (by anevilyak): Replying to [comment:2 kvark]: > Thank you anevilyak. It would be very useful if I could really force the resolution from the boot menu, regardless of the driver used. The reason it doesn't work that way is because it can't really. In the case of VESA the BIOS gives you a list of resolutions to choose based on an index value you pass in, and takes care of all the rest from there since it's all standardized. When using the actual driver, you no longer have the benefit of that, and consequently the driver has to actually compute the modelines, which entails computing constraints based on the monitor, etc., and consequently a lot more information potentially has to be supplied. -- Ticket URL: <http://dev.haiku-os.org/ticket/8457#comment:4> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
