Comment 10 for bug 1268151

Have not tried that. it's kind of difficult to reconnect it that way.

The thing is that this has worked perfectly from ubuntu 10.10 (Maverick Merkeet) all the way to Saucy Salamander. so perfectly fine with a nVidia card and an Onkyo receiver for more than 3 1/2 years.

I upgraded the video card from an older GT 220 to a GT 640 late last year. But that setup was working fine for months with Saucy Salamander.

The trouble only started from two Saturdays ago (22nd March 2014) when I upgraded to Trusty. The "new" trusty nVidia driver (version 3.31) was working fine in Saucy as well (as I needed to upgrade to that to support the GT 640).

I've tried the following in Trusty with no results

1) tried the ubuntu and xorg-edgers version of the nvidia 3.31 driver. also tried the nvidia-331-updates package from ubuntu as well

2) tried the nvidia 3.34 driver from xorg-edgers

3) disabled all power management using xset, commands in xorg.conf and installing xscreensaver and setting it to disabled. this is working as the screen never goes off.

4) rebooted into the saucy linux kernel (3.11-20) that used to work. same effect as the trust 3.13 kernel.

5) updated everything from xorg-edgers

not sure what else to try. I doubt this is a hardware issue as the same setup just used to work with the previous ubuntu version. no cables, hardware etc. have changed. except for the software upgrade.

Any ideas?
