Public bug reported:
I have just installed Ubuntu 14.04 64-bit on my Toshiba Portege R600-10Q
laptop (a model from 2009). I am now trying to display the desktop on a
BenQ Senseye3 22" monitor, via the vga output, but it's not working -
the monitor says "No Signal Detected!".
What I've done:
I have gone into "Screen Display", where I can see the monitor is detected by
the laptop.
The monitor has a 1920 x 1080 native resolution, which I have tried to use, but
I have also set it to lower resolutions, e.g. 1024 x 576.
I have tried to use the monitor in dual screen, mirrored and single screen mode
- none work.
I have tried pressing Fn + F5 to get single screen output - the laptop screen
goes blank, but still no output on the monitor.
I have tried several monitors (of the same type, and also of a different make),
so I don't think it's that.
If, and only if, the monitor was plugged in to the PC's vga output
during boot up, then the display outputs to the monitor correctly. But
if I plug the vga cable in after boot up, then the monitor receives no
signal.
The laptop has the Intel® GS45 Express chipset for graphics
acceleration. I installed mesa-utils and ran glxinfo in a terminal.
Amongst the output was:
OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset
Also, in the "About This Computer" window I see:
Graphics: Mobile Intel® GM45 Express Chipset
I wonder if the problem is that my chipset is GS45 not GM45.
One last thing. The output of "sudo lshw -C video" is:
