2013-08-17 21:26:02 penalvch 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 More details are below: 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.
