I beg to disagree. - Debian does have it enabled by default. - I have always used it on all my machines without any problems. - Both my laptops and my desktop suspend and resume perfectly with vesafb and X.Org. - Jesse Barnes seems to disagree with you. To quote from the BR cited above (comment #11): "and you're right, making things work with vesafb isn't unreasonable". I do know intelfb is considered to be terminally broken, but have always understood the use of vesafb to be accepted. > As I said having two drivers thinking they own the GPU is a recipe for > total disaster and thats why we've designed the new KMS code so you can > get cool bootup logos and avoid the insanity dance. Yes, and I really welcome the great progress being made there. But for me it's not yet an option as I run Debian stable on these boxes. > However we shall endeavour to fix this issues as it may be systemic of > something else going wrong in the new PAT/AGP code. Great. Thanks in advance, I do appreciate it. BTW, today I noticed another regression, but I have not yet looked into it deeply. When I suspend I normally see at least some console messages from the suspend procedure on the framebuffer console, but with .31-rc2 I only see a cursor. It does not really affect the suspend/resume. Could possibly be related. Will investigate further. Cheers, FJP
