[Bug 751453] Re: External monitor doesn't work on Toshiba Portege R600

 

Sorry for not responding to the comments sooner. I'm not now using the
R600 to connect to external displays, and I haven't got much time to try
out the latest ISO (especially if it would need to be installed on disk
- I  could run live it might be OK). So I'm happy to let this bug lie.

Title:
  External monitor doesn't work on Toshiba Portege R600

Status in The Linux Kernel:
  Incomplete
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  In summary, when an external monitor is not connected at boot, I can't
  get the laptop to drive an external monitor. This is a problem in
  Ubuntu Lucid (10.04) but it was not a problem in the Ubuntu Hardy
  (8.04).

  This appears to be a problem with the mainline kernel. I have
  submitted a report at:
  https://bugzilla.kernel.org/show_bug.cgi?id=31292

  WORKAROUND: In the BIOS change "Power on Display" from "auto-selected"
  to "LCD+Analog RGB".

  External monitor not connected at boot
  --------------------------------------

  * External monitor can be seen in "Monitor preferences", but laptop
    does not drive external monitor

  $ xrandr -q
  Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192
  VGA1 connected (normal left inverted right x axis y axis)
     1360x768       59.8
     1024x768       60.0
     800x600        60.3     56.2
     848x480        60.0
     640x480        59.9     59.9
  LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
     1280x800       60.2*+
     1024x768       85.0     75.0     70.1     60.0
     832x624        74.6
     800x600        85.1     72.2     75.0     60.3     56.2
     640x480        85.0     72.8     75.0     59.9
     720x400        85.0
     640x400        85.1
     640x350        85.1
  DVI1 disconnected (normal left inverted right x axis y axis)

  * "Mirror screens" in "Monitor preferences" appears to switch
    resolution, but the external monitor is not driven. In this case
    xrandr reports:

  $ xrandr -q
  Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
  VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
     1360x768       59.8
     1024x768       60.0*
     800x600        60.3     56.2
     848x480        60.0
     640x480        59.9     59.9
  LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
     1280x800       60.2 +
     1024x768       85.0     75.0     70.1     60.0*
     832x624        74.6
     800x600        85.1     72.2     75.0     60.3     56.2
     640x480        85.0     72.8     75.0     59.9
     720x400        85.0
     640x400        85.1
     640x350        85.1
  DVI1 disconnected (normal left inverted right x axis y axis)

  * I can't use toshset to connect external monitor:

  $ sudo toshset -video both

  This makes the screen go blank and the  external monitor is not
  driven. I can recover switching to VT1 and typing "sudo toshset -video int".

  * Changning the output using the proc file system does not appear to
    work as it should (See http://memebeam.org/toys/ToshibaAcpiDriver
    and http://memebeam.org/toys/ToshibaAcpiVideo) :

  # cat /proc/acpi/toshiba/video
  lcd_out:                 1
  crt_out:                 0
  tv_out:                  0
  # echo "crt_out:1" > /proc/acpi/toshiba/video
  # cat /proc/acpi/toshiba/video
  lcd_out:                 1
  crt_out:                 0
  tv_out:                  0

  Workaround: External monitor connected at boot
  ----------------------------------------------

  The external screen is driven automatically. The resolution of the
  laptop screen is adjusted to match the external monitor.

  It's not possible to turn off the monitor using the proc filesystem:

  # cat /proc/acpi/toshiba/video
  lcd_out:                 0
  crt_out:                 1
  tv_out:                  0
  root@bancroftmill:/home/dcs# echo "crt_out:0" > /proc/acpi/toshiba/video
  root@bancroftmill:/home/dcs# cat /proc/acpi/toshiba/video
  lcd_out:                 0
  crt_out:                 1
  tv_out:                  0

  It is possible to switch using the "Monitor preferences" tool.
