Re: Video problems - NVidia/Nouveau
A couple of points
Check the temperature of the card too. Try and see if increasing the load on it can trigger the condition. Also compare the cards diagnostics in Linux and Windows.
I can do the first two, but not the third (no Windows around here).
nouveau-pci-4000 Adapter: PCI adapter temp1: +81.0°C (high = +100.0°C, crit = +120.0°C)
That's with the machine mostly idle.
As far as I am concerned that temps way to high for an idle video card, if its the cards real temp. Next time you turn the system on try to read the temp as soon as possible to see if starts out near room temp. Even being pushed with a lot of 3D work the temps on my system, video card being a Radeon 5870, rarely exceed 65 degrees C. If the temp is real may be the card has an air flow restriction, say to many cables around the place, or if it has a fan it requires cleaning and a drop of oil. Second point may be minor, I am slightly suspicious of the monitor not coming back after being switched off and on. I have struck some older monitors that will not sync to a high resolution signal when restarted but it would be rare these days. Using Linux now for a few months under twenty years, Lindsay
Agreed. This is why testing it in the environment it was (sadly only) engineered to work in ie. Windows would give a useful baseline. Can you try it with an Ubuntu live cd instead? Those guys do nice stable stuff with driver/setting combinations. On 20/03/13 20:05, zlinw@mcmedia.com.au wrote:

Yes, that's possible. The problem is that it's only intermittent, but I could try a number of reboots into the CD, I suppose, with a family member or friend watching the screen that I can't see... My other option is a kernel upgrade in case one of the Debian patches on the way toward their stable release is involved. I still have strong suspicions about the hardware though.
