scrambled display after entering "power saving?" state
Ladies & Gentlemen.
I am sorry if this should be posted in a different fourm
I need some advice on where to look to find the cause of a scrambled display.
This is a clean install. However, this is one of the reasons for the clean install.
What happens / happened:
HP dv9000 laptop
most recent nvidia driver
Debian Testing (this weeks image) (was suppose to default to kde but I got gonome)
I had the typical nvidia setup issues and after I got the dependencies installed the driver installed and the gui came up.
However, when I shutdown the xserver I get a scrambled display. What I mean. Sometimes it is divided into 4 sections (I have 4 virtual displays) and I can see the two on the left, one over the other, and on the right side of the screen I can see a portion of the other two. At other times I have two columns displayed with blue vertical lines and on the left side of each there is a columns that I can tell is displaying the shutdown messages but they are very small (pencil eraser size).
This happened with the previous install too, after I reinstalled the nvidia driver so that I could use the gui with the ~.22-3 kernel.
I just logged out and tried to do a console login and got a bunch of blue vertical lines but I could not see the prompt.
The display also enters this corrupt state if the display is allowed to enter what i think is a low-power state. But I have not enabled the screensaver or power management in the display configuration. I had thought that it should not enter this 'low-power' state.
It does not do this if I boot to single user mode from grub.
So, how do I determined if this is a bug or some kind of config problem?
Where do I look first?
This is outside the scope of my past experience.
I did find a post that said the frame buffer will conflict with the nvidia drivers and to change the vga= option in grub but that option is not set in my menu.lst.
My son's machine that is also a fresh Debian testing (older cd) install has a similar problem, haven't actually watched it, he only told me about it. He is using an intel processor where I am amd, but we are both using the most recent nvidia graphics driver from there site (169 something). His is desktop, mine is laptop. He is i686-32, I am amd64.
Still searching but not seeing very much that relates.
Thanks to all.
