Hi Lenz I think you need a special modeline for this. --> cvt Best regards, Stefan On Sun, Jun 03, 2007 at 08:26:18PM +0200, Lenz Grimmer wrote:

Hi,

I have an IBM Thinkpad T42 with a 1400x1050 internal screen connected to an ATI Radeon Mobility 9600 GPU, which I used in a dualhead configuration with an external Samsung SyncMaster 920T TFT screen. I enabled MergedFB with the following MetaMode and all worked well: "1400x1050-1280x1024".

Now I replaced this external display with another Samsung flatscreen: a SyncMaster 940BW, which is a wide-screen display with 1440x900 pixels. I added this new resolution to the Screen section and added an appropriate MetaMode for MergedFB: "1400x1050-1440x900".

However, the X server (X.org 7.2 on an openSUSE 10.2 installation, xorg-x11-7.2-146.7) does not accept this mode with the following message:

(WW) RADEON(0): Mode "1440x900" is not a supported mode for CRT2 (WW) RADEON(0): (Skipping metamode "1400x1050-1440x900")

It then falls back to the "old" mode (1400x1050x1280x1024), which does of course not look too good on this widescreen display.

I have toyed around with various other options and also tried to create a fresh xorg.conf file from scratch using SaX2, which did not really help or make a difference. I am stumped.

Does anyone have an idea what may cause this? Any help would be appreciated - pleased find my xorg.conf file and the Xorg.0.log file (gzipped) attached for details. Thanks!

Indeed, this did the trick! At least it's using its native resolution now - I added the following mode line to the Modes section (see new file attached):

Modeline "1440x900" 106.5 1440 1520 1672 1904 900 903 909 934

However, I now face one remaining problem: as the vertical resolution on the external display is lower than the one on the internal panel (900 vs. 1050 pixel), the screen on the second head now scrolls up and down when I move the mouse over the upper or lower screen border.

According to the radeon man page this should be fixed be enabling the MergedNonRectangular option, which I did:

Option "MergedNonRectangular" "true"

Unfortunately the screen still scrolls, which is slightly annoying. Strangely enough this worked fine with the previous monitor (which had 1024 pixel vertical). The X log file is attached - what could be the cause of this?

Try "MergedNonRectangular" together with Option "CRT2Position" "RightOf 150" Best regards, Stefan Public Key available ------------------------------------------------------ Stefan Dirsch (Res. & Dev.)
