thanks
Since this bug has gone unacknowledged for 10 months, and the package
is still unusable (fixed freq monitor, remember? And it is getting
increasingly hard to keep xorg 6.8 installed with the dependancy
demands of the rest of the system), I am reassigning it to the ati
driver which now explicitly exists, as well as marking important, in the
hope that this gets noticed.
Summary: X6.9 and 7.0, and 7.1 all completely ignore the presence of the
modelines I supply, even when I supply Option "Display" "CRT"
It doesn't even apparently read it in, so when I ask for a specific
modeline to be used, I get told
(II) R128(0): Not using mode "IBM_mode_1" (no mode of this name)
even though it has just told me it is ok with the user supplied
hsync/vsync range:
(II) R128(0): IBM: Using hsync range of 50.00-120.00 kHz
(II) R128(0): IBM: Using vrefresh range of 50.00-160.00 Hz
It does happily tell me however that it is going to use the LCD panel as
soon as it acknowledges that it realises that I asked for the CRT display:
(**) R128(0): Using external CRT for display
(II) R128(0): Primary Display == Type 2
(II) R128(0): Panel size: 1024x768
(II) R128(0): Panel ID: Samsung LT141X8-L02
(II) R128(0): Panel Type: Color, Single, TFT
(II) R128(0): Panel Interface: LVDS
(II) R128(0): PLL parameters: rf=2700 rd=12 min=12000 max=27000; xclk=10500
Indeed, when I start up X with the external layout:
startx -- :1 -layout IBM
I get a garbled output on the CRT (it's garbled because a 1280x1024 fixed
freq monitor doesn't like 1024x768). When I use the bios hotkey on the
laptop to switch over to LCD display, it displays the 1024x768 screen on
the 1024x768 display -- ie, it never attempted to allocate a 1280x1024
screen.
Log and config files are included in earlier messages. If you need an
updated copy, fine, but I seem to recall the debian bug tracking system
balks at large attachments?

You're saying cats are the opposite of bijectiveness?
