[opensuse-factory] manual for console modes while KMS=yes
Now that my Factory is using (32 bit) 2.6.32-desktop, apparently using KMS by default, my i845G consoles, after starting in their usual vga=0x305 1024x768 mode, jump into some lowfi mode that is or approximates 640x480. I get same result with i915.modeset=1. No man pages for randr, framebuffer or kms, and man page for kernel does not address kms. Nomodeset on the kernel line makes consoles behave OK, but X cannot find any screens with a usable configuration (no kernel modesetting driver detected). How do I keep whatever benefits I'm supposed to get from KMS and yet initialize tty[1-6] back the way I'm used to, and have them stay that way, or can I? Is KMS broken for older Intel chips? (currently I have X starting @ 1600x1200x16bpp) Note, it seems pae kernel does not yet have KMS. If I boot it instead, vga=0x305 works as before, but X cannot find any screens. With desktop kernel, i915.modeset=0 on kernel line causes same behavior as pae kernel. http://en.opensuse.org/Special:Search?search=kms&go.x=0&go.y=0&go=Go got me only 4 hits, none of which seem to be docs in an expected form, but did point me to Eich's KMS announcement post on this list, where I found we using openSUSE are to use nomodeset instead of nokms like with other distros' KMS kernels. -- "Our Constitution was made only for a moral and religious people.

I assume it's 800x600.

No, I've been using it on older chips and it works fine. Could there be a problem with DDC readout? Either on your monitor or the cable might be bad. You could make a bugzilla entry which can be passed on to Intel.

I don't know what you are talking about. There are other distros which use nomodeset. Cheers, Egbert. -- Egbert Eich (Res. & Dev.)
