<div dir="ltr"><div><div><div><div><div><div><div><div><div>Hi there.<br><br></div>I did an update to my ubuntu 12.04LTS box yesterday. Small update...<br></div>While it's usual for major ubuntu upgrade to break stuff (but that's another topic)<br>
<br></div>It upgraded nvidia drivers from 295.40 to 304.88 ; which was quite surprising as usually it never do such a big steps in LTS release.<br><br>Anyhow: it is very broken.<br></div><div>This is on my main backend, which is also used as a frontend in my cinema room (plugged to a cinema projector)<br>
<br></div>As soon as I turn off the projector, when I turn it back on I get no signal from the PC. I must then restart X / Window manager to get video signal going.<br></div>Interestingly, if from the command line I start a VDPAU playback, signal comes back again (sometimes, not always), without having to restart X.<br>
<br></div><div>Reverting back to 295.40 fixes all issues and for now, I've locked that version<br><br></div>my xorg.conf hasn't changed much in years. I use the CustomEDID command so I can boot the PC even if the projector is off.<br>
<br></div>Anyone has experienced similar issues with 304.88?<br></div>I'd like to find the problem with those drivers because sooner or later, I would have no choice but upgrade :(<br><br></div>Thanks<br></div>
