R600/r700 kms - no go

[netkas]

Ubuntu 9.04 system, hd4850

compiled/tried two kernels - latest from drm-next(few days old git) and 2.6.32-rc3-git3
xf86-video-ati from git

booting with argument - radeon.modeset=1 results in black screen as soon as X starts, system still working.

if i try to switch to console (ctrl-alt-f1) system seems to freeze (no reaction on caps lock pressing).

tried also with and without vesafb module builtin(with option vga=838)

no go at all.

what can I try ?

also tried to boot with single option then modprobe radeon, seems it worked once, for console

Are your libdrm and mesa also from git?

Are you sure you disabled all framebuffer devices?

[netkas]

yes, those from drm..

disabled all fb devices ?

vesafb and etc ? nop, it works if i boot without radeon.modeset=1, then modprobe radeon modeset=1

I have a screen this way, but X11 kills it when it starts

and no matter was vesafb loaded or not

Ahh, no I see, ./configure for ati driver says kms : no

so, Updated xorg server to 1.6.3 (xf86-video-ati configure output needs to be more imformative)

recompiled ati driver and all works fine, except that i have to manualy make - modprobe radeon modeset=1 , otherwise black screen when X starts

if I add radeom modeset=1 to /etc/modules, then i get half of screen visible, and another half is black, system freeze.

without passing vga=838 options to kernel - freeze as soon as radeon modeset=1 loaded

you need to load fbcon to get console once the drm loads.

console is working when drm loaded, but sometimes (rarely) it gets me black screen.

When booted with radeon.modeset=1 (or radeon modeset=1 added to /etc/modules, or another way to load module automaticaly) - i get black screen when X starts up

Only way to get it working - boot with option - single, then modprobe radeon modeset=1, then resume booting.

I'm having the same problem. I use Ubuntu 9.10 with xorg-edgers and kernel 2.6.32-rc6 from Kernel PPA, with a Radeon HD2400.

When using KMS (through "option radeon modeset=1" in /etc/modules), as soon as X starts, I get a blank screen and the system freezes.

[netkas]

tried 2.6.32-rc7.

All the same, even worse, with rc5 if I run xinit glxgears -- /usr/bin/Xorg -ac -config /etc/X11/xorg.conf , with previously loaded radeon (modeset=1) - it always was woeking.

Now with rc7, half of time I'm getting system freeze with lower half of screen showing some pic with colored snow.

[agd5f]

you might try Dave's drm-radeon-testing branch.

[d2kx]

agd5f (or some other dev),

do you already know if you will be able to enable KMS by default in Linux 2.6.33 or 2.6.34?

I am asking because Ubuntu Lucid will be using Linux 2.6.33.

[bridgman]

KMS is already enabled by default in Fedora 12, and it looks like the bulk of the KMS fixes are making it into 2.6.32, so it *seems* likely that 2.6.33 would be suitable.
