[ltp] ATI Driver 8.10.19 not working on DVI

[Paul R Streitman]

I get one or the other.  I did not try for dual head or simultaneous
display and do not know whether they are possible with ATI's driver and
DVI.  I have never been able to switch between external and internal
displays (without restarting X) with a Radeon chipset thinkpad.
Personally, I do not see it as valuable anyway as most external monitors
will not do 1400x1050 and I certainly would not want to run my thinkpad at
a lower distorted res.

Perhaps Alex will comment, but I have observed with both ATI's driver and
the xorg Radeon driver that attempting to run the thinkpad LCD in other
than native resolution results in a strange display with the image in the
upper left and 'bars' of color to the right and below it.  Also, neither
driver correctly detects what my external display is capable of providing
and I have to coerce it to the correct 1280x1024.  That is why I have two
layouts in the profile.

Thanks for the xorg.conf. Do you get display on both the laptop screen and
the
external LCD (connected via DVI) together? Or, do you get only one of them?

If you get only one of them, can you switch from one to another without
having to restart X?

thanks,
Osho
