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)
Created attachment 11488 [details] Xorg.0.log
can you post your config as well?
Well, I only changed Option "GartSize" "64" Option "XaaNoOffscreenPixmaps" "true" and Virtual 1400 1050

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)

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) > > 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) > you can add 1280x1024 to the modes line in your screen config or add the mode at runtime using xrandr xrandr --addmode LVDS 1280x1024
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?
Can you try again with ati 6.7.19x or ati git master?
I'm using 6.7.195 and I'm on ubuntu gutsy. I don't know if there are updated packages... I will try to update to the pre-alpha version of ubuntu to see if it helps

is this still an issue with a newer xserver/driver?
I don't have anymore that monitor.
Closing this bug as it can't be confirmed anymore.
