This bug was triggered by different color depths in the two screens driven by the same MGA card. Is it even possible to configure the new version that way? The HowToRandR12 page recommends defining only a single screen in xorg.conf and then configuring multiple outputs while the X server is running. Has the bug been fixed by removing the feature? Being unable to define different screens is a problem because it makes xsm (of x11-utils 7.3+1) divide its window halfway between the two monitors. The window manager would normally prevent this, but it is not yet running at that point because xsm will start it as part of the session, thus allowing me to have different window managers for different sessions. One of the monitors I am using is a fixed-frequency HP A1097C, which does not support DDC. It thus appears I now have to set the modes in /etc/X11/xdm/Xsetup (attached). There are a few other problems with the new versions (xserver-xorg-video-mga 1:1.9.100.dfsg.1-1 and xserver-xorg 1:7.1.0-7) as well: - I don't get a mouse cursor on the second monitor. At first I thought it might be some presentation feature, activated when the monitors are displaying the same picture otherwise. However it also happens when they are configured side by side. - If I configure "Virtual 2648 1024" to snugly fit the 1280x1024 and 1368x1024 pixel outputs side by side, the Debian logo in the xdm login window appears correct but the window itself is badly sheared, appearing as a centimeter-wide strip that wraps thrice through the sides of the screen. - The DoubleScan flag seems to be ignored on the VGA2 output. I am not entirely sure it worked in the previous version either. However, the same mode works correctly on the VGA1 output.
