I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. The laptop has a Intel 4500 video card. I've tried two approaches:

  1. Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing.
  2. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes.

In both cases the only way to turn off the laptop is holding the power button.

I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result.

Any hints?

Possibly fixed in newer kernels. – codeape Oct 25 '11 at 9:21
@codeape I'm with the last kernel shipped with 11.10, still have the same problem – Felipe Hummel Dec 22 '11 at 18:39

I am having the same issue with my Vaio VGN-FW351J. I originally was using ubuntu with the gnome desktop and thought it was an issue from the upgrade to 11 and installed kubuntu over it. It had the same issue, freezing up when plugging in the hdmi. I wonder if this is a problem with Vaio drivers for hdmi output. Anyway, let me know if you find a fix.

A workaround I found out is to set the laptop to stand by, wait, connect hdmi, and wake it up. And do the same thing to remove the cable. – Felipe Hummel Jan 7 '11 at 4:34
