Bug Description

Binary package hint: xserver-xorg-video-ati

testing ati driver for gutsy
6.7.192-1ubuntu1

I have a laptop with an lcd screen of 15"
the native resolution is 1400x1050 it is correctly detected, but see the list
of resolutions:
1400x1050 60.2*+
  1280x800 60.0
  1280x768 60.0
1024x768 60.0
800x600 60.3
640x480 59.9

1280x800 & 1280x768 should not be there, sine they are not for 4:3 screens and
should be substituted by 1280x1024 (I think)

Changed from what? You haven't attached your config. Anyway, it looks like what's going on is that the server is attempting to add the various server modes, many of which (including the 1280x1024 modes) are being rejected for various reasons. The 1280x800 and 1280x768 modes are being validated and allowed. This isn't really a problem a per se as any mode other than 1400x1050 will use the panel scaler.

Changed in the sense that there were no additional options in the section Device. I don't have here my notebook so I cannot attach xorg.conf

I didn't understand why 1280x1024 is rejected and 1280xother not, since they are not "native" for 15" 4:3 panels.

PS: I need to use 1280x1024 when I attach the external screen since the maximum resolution of the screen is 1280x1024. and if I keep my panel to 1400x1050 the image in the external screen is truncated at the bottom and right (because it has a smaller resolution)

the only mode that is "native" is 1400x1050. Everything else is scaled. it makes no difference to hw. besides you might want to match your modes to another output device (beamer on a VGA port for example) that supports that mode. The log says why the 1280x1024 modes were rejected:
(II) RADEON(0): Not using default mode "1280x1024" (hsync out of range)
(II) RADEON(0): Not using default mode "1280x1024" (vrefresh out of range)
(II) RADEON(0): Not using default mode "1280x1024" (vrefresh out of range)

you can add 1280x1024 to the modes line in your screen config or add the mode at runtime using xrandr
xrandr --addmode LVDS 1280x1024

Some conclusion from upstream :) Actually, I don't know, but we have been told by the bug squad to take the bug out of "New" as soon as it has been looked at and commented to. I guess it should at some point be confirmed as a bug, or closed as an invalid one. Upstream doesn't really think it is a bug, from what I can see.

still present in 6.7.194

I really don't understand why upstream thinks this is not a bug...
Have you understood?
If the resolution does not match with my panel size it must not be added!

Tormod Volden (tormodvolden) wrote : Re: 6.7.192 resolution not correctly detected

Well, xrandr lists all possible modes, whether they make for a stretched picture or not. This is actually useful, in case you want to clone it to an external, different screen.

ok, now I understood, but I still not understand why X thinks that
1280x1024 is a wrong resolution:

(II) RADEON(0): Not using default mode "1280x1024" (hsync out of range)
(II) RADEON(0): Not using default mode "1280x1024" (vrefresh out of range)

I don't see the detected hsync/vrefresh ranges in your log, but apparently they exclude the 1280x1024 modes. Please attach your xorg.conf, and try also without one. Is this with the "-tv2" ati driver?

I am wondering a little about the HOverplus value in your log, mine for instance is 24.

(WW) RADEON(0): LVDS Info:
XRes: 1400, YRes: 1050, DotClock: 108000

well, I don't know what it is. Can this value be viewed in windows xp,
so we can do a comparison?

Can you attach the log from using the attached package? It includes a bit more LVDS info.

Looking at the log in the original bug report in https://bugs.launchpad.net/bugs/137626 I can see some strange HOverPlus value of 32808. Is it wrong in the BIOS or is it decoded wrongly by the driver? Can this exclude otherwise acceptable modes?

In my newbee opinion, LCD monitors have their own screen resolution so gutsy sometimes shows out of the square mainly the scrolling bar on firefox is dificult to point with the mouse. I always have to proceed with auto adjustment for colors, brightness and screen position.
I wonder if this is not one of the reasons that radeon cards (RV350 mine) sometimes scrambled the screen or display a black screen.

I mean in some parts of the Xorg.0.log file xorg.conf defines Radeon display dimensions as (380, 300) mm but there are different size in other parts.
Ex. (**) RADEON(0): Display dimensions: (380, 300) mm
      (II) RADEON(0): Setting screen physical size to 376 x 301

Yes, "Setting screen physical size" sounds like the best hack ever :) This small deviation shouldn't cause any problems though.

Thanks for taking the time to report this bug and helping to make Ubuntu better. In the development cycle for Intrepid there have been some vast improvements in the open source ati video driver and we could use your help testing them. Could you please download the latest Alpha CD image of Intrepid and test this particular bug just using the Live CD? You can find the latest image at http://www.ubuntu.com/testing . Your testing can help make Ubuntu and the open source ati driver even better! Thanks in advance.

I don't have an ati card any more. Now I have an intel, and a widescreen.
The resolutions offered are 1280x800 (which is native) and 1024x768,
800x600 and 640x480
maybe this is not a problem because 4:3 resolutions can be viewed in
16:10 screens too

I think this bug should be closed, since showing also non-native
resolutions could be a wanted behavior
