Bug#687461: xserver-xorg-video-radeon: HD 6310 video gives only colored snow/black screen

Alex,

Thanks for your reply.  When I boot and append

radeon.modeset=0
I can get the display fixed, although Gnome 3 starts in failsafe (apparently classic) mode. This I can live with. 

$lsmod | grep firmware gives:

radeon                639188  0
ttm                    48725  1 radeon
drm_kms_helper         27227  1 radeon
drm                   167670  3 drm_kms_helper,ttm,radeon
power_supply           13475  1 radeon
i2c_algo_bit           12841  1 radeon
i2c_core 23876 5 i2c_algo_bit,i2c_piix4,drm,drm_kms_helper,radeon 

So I think the drivers were loaded as kernel modules.
Maybe this bug should be marked as 'solved' (if you consider it a bug at all)? 

Thanks,
Mike

Dear Alex,

Thanks very much for your reply.  I wasn't sure whether to reply-all of not,
so I didn't.

The live install includes firmware as follows:

$more binary.packages | grep firmware
firmware-linux-free     3.1

Should I see if I can compile in firmware-linux-nonfree as well?  But
according to
http://packages.debian.org/wheezy/all/firmware-linux-nonfree/filelist
this doesn't exist for wheezy?


I'm not sure how debian packages it, but you need the firmware to use
the card.  If you've compiled the driver into the kernel, you'll also
need to compile the firmware into the kernel.



There is an initrd in the live image:

$more binary.contents | grep initrd.img
/live/initrd.img

I grepped the build log for firmware and got the following (only warnings
having to do with networking):

$more log | grep firmware

[ and 23 more similar warnings about rtl*8168*.fw for module r8169 ]

In the build log these warning occur as update-initramfs is generating
/boot/initrd.img-3.2.0-3-amd64.

I also grepped the log for initrd and got the following:

$more log | grep initrd
update-initramfs: Generating /boot/initrd.img-3.2.0-3-amd64
update-initramfs: Generating /boot/initrd.img-3.2.0-3-amd64
update-initramfs: Generating /boot/initrd.img-3.2.0-3-amd64
update-initramfs: Generating /boot/initrd.img-3.2.0-3-amd64

Does this mean that the firmware is included in the initrd?

Excuse the simple question, but: is there a way I can pass an argument at
boot to get at least a non-X terminal window to do further diagnosis?


boot with radeon.modeset=0 on the kernel command line in grub.



Failsafe boot gives the same problem.  Maybe I will try generating a live
build without X, and then maybe we can troubleshoot by adding X to that
install (I do not yet know if a live-build on a usb stick can be modified
this way).


You can also append a non-X runlevel to the end of your kernel command
line in grub to boot to a non-X environment.  I'm not sure what
runlevel debian uses for non-X.

Alex



Thanks,
Mike

Dear Maintainer,

I get no video, only colored snow.  Boot seems OK up until X is started.
The system is then unusable.  (I am writing from a different wheezy
install).



Make sure you install the firmware package and that the firmware is
available in the initrd if you are using one.

Alex
