Public bug reported:
Hello,
I am presently running Feisty Fawn fine on my ThinkPad T40. I have set
up a custom way for Ubuntu to detect an external screen on boot, and
then ask to ask me whether I wish to mirror or extend onto the external
screen.
As such it was with a great deal of interest to use the new Screen and
Graphics Preferences tool to see how it fared.
I have tried this using the detected graphics driver (ati (radeon)) in
the driver selection and not changed that. I have done this with the
external screen plugged in on boot and plugged in after boot.
When I chose my external display as a Generic 1024x768 LCD monitor
having booted with it plugged in, and chose 1024x768 for the resolution;
and chose mirroring, and clicked Ok, I got a crash report, unfortunately
I could not send it because I did not have my wireless key to connect to
my wireless network. I will try and submit it as soon as I have a
solution.
Trying to do the same having plugged the monitor in after booting, but
this time clicked Test. I got something on the external screen, but the
display was garbled badly on the laptop LCD, and after clicking cancel
on the OK to use it; the whole system froze and would only respond to a
power off.
The T40 has a 32MB Radeon 7500.
The external screen is in fact a 23" LCD JVC TV, but I have driven it
using 1024x768 at 60Hz on Ubuntu 7.04 and Windows 2000. In fact on
Ubuntu 7.04 I run it fine at its odd native resolution of 1360x768.
Any more details you need please ask but it would appear that this does
not work at all at present :(
I am booting and using this from the live CD if that is of use.
Good work otherwise!
Vicky
