Hi Seife,
And on servers it is very useful to be able to blacklist drm, so that KMS does not kick in. VGA-over-serial emulation and other textmode consoles do not work in graphics mode.
maybe there is some magic parameter to stop drm from kicking in, but "vga=0" no longer helps.
Well, how do you "blacklist drm" exactly? My understanding is that drm is only a common helper module for all drm drivers (radeon, i915 etc.) so a "blacklist drm" statement should have no effect, should it?
"find /lib/modules -name drm.ko | xargs --no-run-if-empty rm" :-) This effectively fixes all attempts to load any kms module, because they all need drm. Oh -- and drm is *big*, so that's another reason to have it as a module. Loading a module from disk once the kernel is running is probably much faster than loading the bigger kernel from disk / network via the BIOS routines the boot loader is using.
Also KMS can be disabled with nomodeset=1 or whatever the exact boot command line syntax is these days.
If vga=0 no longer works as it used to, maybe this should be reported as a bug.
Well, it is working as before: the VGA driver does use 80x25, but in the good old times of vesafb it also did tell vesafb to not do anything, but this has changed now. If this is a bug -- I don't have the energy to discuss. All I know is I don't want kms on any server ever. Because this will force me into using Java or .NET consoles instead of using plain SSH to the management board.
* I suppose fuse is only used on desktop machines by default, for gvfs, so having it as a module seems OK.
You would not believe how many servers need to mount NTFS file systems :-) ntfs-3g is implemented with FUSE.
Well, if there is a consensus that almost all machines need fuse for one thing or another, I really have no problem having it built into the kernel, if there is no reason not to (KMP, blacklisting or anything else.) Miklos, can you think of any reason why having fuse built into the kernel would be a problem? -- Stefan Seyfried "If your lighter runs out of fluid or flint and stops making fire, and you can't be bothered to figure out about lighter fluid or flint, that is not Zippo's fault." -- bkw -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
