I installed 6.2 on a test system that uses an LCD monitor that uses 1280x1024 at 60-70 Hz with a max horizontal sync rate of 64 kHz. This is a typical 19" LCD. On 6.1, the video was outside of the monitors sync range and I got no display. Changing the xorg.conf file fixed the display once UT was up (techniques already documented on this forum). The vga= mode needed to be changed on the grub boot line to get video during boot and shutdown.
On 6.2, the grub vga mode worked ok, but the Xserver configuration was out of sync range, just as with 6.1. This problem has become unsoluble: the xorg.conf file is no longer used when configuring the Xserver. There is a new file, unique to untangle (xorg-untangle-...??.conf) that drives the Xserver, and that file is re-created at every boot. Changes to xorg.conf were ignored. The standard resolutions did no go down far enough to ever allow me to see the whole virtual screen on my display. So configuration was very difficult.
So, how am I supposed to customize the video modes for X? Further, why should I? Why let Debian choose a video mode beyond the sync capability of most UT customers as a default? Why not set the Xserver to use a set of lower resolutions more typical for a monitor on a server rack.
