Default Bug#585600: linux-image-2.6.32-5-686: KMS does not detect display resolutions

Package: linux-2.6
Version: 2.6.32-15
Severity: normal

Hi.

Since the latest radeon X driver has entered testing, KMS is enabled on my machine, which results in display resolution badly configured with my monitor. I used to have 1280x1024 and no longer have (the fallback 1024x768 is set).

The dmesg messages about EDID being wrong show the problem.

Maybe this is linked to a KVM display switch being present ?

In any case, this is all fine again if I change modesetting to off in /etc/modprobe.d/radeon-kms.conf.

Thanks in advance.

Best regards,

FYI, the following workaround allowed me to keep using 1280x1024. I've added the following lines to /etc/gdm/Init/Default :
xrandr --newmode "1280x1024_60.00" 108.00 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync
xrandr --addmode VGA-0 1280x1024_60.00

Now, I can select the preferred mode with gnome-display-properties and it is kept across session restarts.

Hope this helps.

Best regards,

That seems likely. Can you attach an X log with kms disabled?

Here you are.

Note that I had set
Option "IgnoreEDID" "on"
some time back... maybe for similar reasons...

Tell me if you need more details.

That would be a possible explanation, yes... however I'm not completely
sure... any way to try and confirm this diagnostic for sure ?

I'd be perfectly happy to have one bug less open on the kernel, but I
think there's a problem here that is not fixed at all. Of course, I
could manage to workaround by passing args to the kernel, but that looks
like a regression from end user perspective : how comes that without KMS
things work OK, and with, it doesn't ? Maybe it could be reassigned to
another faulty package ?

Maybe the problem is not with the kernel and with the X driver, then, as
I have :
Option "IgnoreEDID" "on"
Option "PanelSize" "1280x1024"
in /etc/X11/xorg.conf

If I get it right, with KMS, if 1280x1024 is not detected as a valid
mode by the kernel, but then, shouldn't the PanelSize setting be
observed anyway by the radeon driver ?

Should I reassign to xserver-xorg-video-radeon instead (I'm reopening
then) ?

Thanks in advance for your opinion.

Get rid of the KVM switch, or try a useful one.

They don't work ok without kms, if you need to override the panel size
and ignore edid.

I don't know. What does the X log look like with kms?

Well... thanks for this suggestion, but that's not very usefull to make
Debian better

[SNIP]

> What does the X log look like with kms?
>

Here are X logs with and without KMS in attachment.

Indeed option PanelSize doesn't seem to be used when KMS is on : the
driver probably doesn't mess with what the kernel has (not) detected.

Since xrandr allows to add another mode setting, no hope is lost I tend
to believe that the radeon X driver may be considered buggy here, then,
and PanelSize needs to be processed when with KMS ?

Thanks in advance.

Best regards,
