Aha, I see that the relevant code for this is here, in ddcprobe.c:
for(i = 0; i < 8; i++) {
...
switch(edid_info->standard_timing[i].aspect) {
case 0: aspect = 1; break; /*undefined*/
case 1: aspect = 0.750; break;
case 2: aspect = 0.800; break;
case 3: aspect = 0.625; break;
}
x = (xres + 31) * 8;
y = x * aspect;
printf("ctiming: [EMAIL PROTECTED]", x, y,
(vfreq & 0x3f) + 60);
So like pheeror says, the 1 aspect ratio is being returned in the case
where EDID is failing.
I see in ddcprobe.sh, it has this code to check for a return value of 1:
...
DDCPROBE="$(ddcprobe 2>/dev/null)"
...
if [ "$?" = "1" ]; then
exit 1
fi
But I imagine there is some code somewhere (maybe in xserver postinst?)
which is not properly checking for this?
Perhaps better logic would be to skip outputting the mode at all in this
case? E.g. something like...
for(i = 0; i < 8; i++) {
...
switch(edid_info->standard_timing[i].aspect) {
case 0: continue; break; /*undefined*/
case 1: aspect = 0.750; break;
case 2: aspect = 0.800; break;
case 3: aspect = 0.625; break;
}
