That's an overstatement, in my opinion. You can always pick the "Advanced" monitor selection method and enter whatever horizontal sync and vertical refresh parameters you want. > "/var/lib/dpkg/info/xserver-xfree86.config" has limitation of 75 Hz @ > 1024x768, why it gets 85 Hz I don't know, but my *Reflex FX*7200 model > 1792E [approx. ~ CTX-1785GM] monitor can do 117 Hz. > "xvidtune" picks up a max of 105 Hz: > > Vendor: , Model: > Num hsync: 1, Num vsync: 1 > hsync range 0: 30.00 - 95.00 > vsync range 0: 50.00 - 105.00 > "1024x768" 113.31 1024 1096 1208 1392 768 769 772 814 -hsync > +vsync Autodetction is a hard problem, for tedious technical reasons having to do with the DDC extension to VESA signaling standards, the multiple DDC implementations out there, the sometimes conflicting versions of those standards that monitors vs. display adapters choose to support, the real-mode x86 programming that is required to perform DDC probing, and so forth. Due to the above unholy mess, I plan to get Debian's X Window System packages out of the hardware detection business altogether. The X server's maintainer scripts will become a dumb interface to the configuration file, and it's going to be up to the installation system to get a hardware detection system in place on the system before configuring the X server. (Strictly speaking, that's already true, but the fact that the X server's maintainer scripts actually *try* to do detection today if it hasn't been done already tempts people to just leave the problem in the X packages' court.) The other advantage to decoupling as I propose is that we can just publish an interface (being a set of debconf templates), and as many "X detectors" as the Debian Project chooses to write and/or maintain can fight for supremacy and userbase. However, don't look for this overhaul before xorg-x11 6.8.2 enters unstable. -- G.
