Bug#290664: [ati] driver does not recognize that the external display is no longer connected
Package: xserver-xfree86
Version: 4.3.0.dfsg.1-10
Severity: normal
Hi there,
most likely this is for the upstream developers, but they are at 4.4 and
as far is I heard Sarge will never go there anyways.
I use an IBM Thinkpad A20m. When I connect to an external display a clone
doesn't work since the refresh rate is only 60hz, which is insufficiant
for a CRT. With the option "nopanel_display" in XF86Config-4 as described
in http://www.xfree86.org/current/ati5.html#16 the internal TFT of the
laptop is switched off allowing for greater resolution and for higher
refresh rates, which is much more important.
When I disconnect the external CRT and restart the X server the internal
display does not come back. Even if I power off the notebook completely
and turn it back on the internal display remains blank on X. I have to
comment out the option "nopanel_display" in XF86Config and restart the X
server in order to get the internal display back on.
This all does not apply to the console, which can be used without any
problems and also reacts to Fn-F7 which switches between internal,
external and display on both. Fn-F7 does not do anything in X.
Thank You,
Malte Schmidt-Tychsen
