I'm not sure this is necessarily a related issue to your earlier one. When you say you "got the unlock dialog", are you saying that video was working fine, you locked the screen, came back later and tried to log back in? If this is correct, was the PC, hard drive and/or monitor asleep? If this is also correct, then the issue involves power-management which is a whole different ballgame. I ask because you appear to have an Nvidia chipset of which I know little. Are nvidia chipsets well supported in Linux?Silent Observer wrote:Well, I thought that had solved things -- the screen behaved very well for a little while, but then it started acting up again. I get the unlock dialog promptly, but after unlocking I usually get 10-15 seconds of continued screen saver, and either a prompt screen refresh with a delayed cursor appearance, or an off-white screen (less bright than a full white on this monitor, with a little buff tone -- no idea of the significance of that) lasting 10-15 seconds, followed by a desktop load but with no mouse cursor for up to a minute. I still don't see anything that really jumps out in logs, but I do see multiple logs with this (no time stamp):
This strikes me as likely to be related; nvLock looks like a function possibly related to nVidia drivers...
Code: Select all
nvLock: client timed out, taking the lock
And would you clarify something for me? Is this the motherboard in your sig? I ask because the P6NGM-L is an MSI motherboard not Asus.
